According to Rikard Söderberg the formula is commitment, business drive, patience and a focus on the end user.</b></p><div>The Wingquist Laboratory is a centre for digital product realisation. Its research has led to software that can perform all types of calculations, from the magnitude of the deviation that can be accepted during mass production of a product or how to design a component so that it is easy to replace from a purely ergonomic perspective, through to how to improve the factory environment where cars are built. </div> <div><br /></div> <div><b>Success factors</b></div> <div>One of the success factors is its close collaboration with industry, which involves the joint identification of new problems and the formulation of research topics – for the benefit of many. Research is conducted in four areas: Systems Engineering Design, Geometry Assurance &amp; Robust Design, Geometry &amp; Motion Planning and Automation.</div> <div>“Since our inception 20 years ago, we have produced <b>770 scientific publications</b>, carried out <b>150 research projects</b> and taken research out to Sweden’s shop floor, through the <b>56 doctoral students</b> who have passed via us out into industry,” says Rikard Söderberg, Director of the Wingquist Laboratory. “In addition, some <b>180 companies</b> have adopted our research into their daily operations in various ways, via our software, methods and other results.”</div> <div><br /></div> <div>The anniversary celebrations will begin on <b>2 December </b>through a digital campaign which includes technology videos, case studies, interviews and discussions. But first let’s take a look back – how and why was the Wingquist Laboratory founded?</div> <div><br /></div> <div><a href="https://www.linkedin.com/company/wingquist-laboratory/?viewAsMember=true" target="_blank" title="link to Wingquist page on Linkedin"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" /> Follow the Wingquist Laboratory’s celebrations</a></div> <div><br /></div> <div><b><img src="/SiteCollectionImages/Centrum/Wingquist%20laboratory/Gerbert-1.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />Challenges of globalisation</b></div> <div>In the 1990s Sweden was strongly impacted by its accession to the EU, the new competitive conditions of globalisation and the fact that digitalisation took off. </div> <div>“This really shook up Swedish industry, especially the motor industry. Ford’s acquisition of Volvo Cars and GM’s acquisition of Saab caused great concern that product development and production would disappear from the country,” says Söderberg.</div> <div>In order to meet the challenges, Nutek (Vinnova’s predecessor) launched a multidisciplinary IT project in the engineering industry. The aim was to investigate how the engineering industry could benefit from academic research into IT and production. Söderberg ran one of the subprojects:</div> <div>“In my ‘3D tolerance management’ projects, we thought a lot about how we in the academic world could support industry. We focused on how we could retain the areas we were good at in Sweden whilst also increasing the use of IT in industry.”</div> <div><em>Above photo: The then Dean of the Mechanical Engineering Section, Göran Gerbert, came up with the idea of starting a product and production development centre focusing on computer-aided simulation and launched an initial preparatory steering group with Hans Johannesson, Anders Kinnander and Rikard Söderberg. </em></div> <div><br /></div> <div><b>Inspired by a Swedish industrialist </b></div> <div>Söderberg, who had recently returned to Chalmers after a spell in industry, was asked if he would like to head up a new centre. The aim was to support product realisation, product development and manufacturing. In addition, industry’s need for production systems with shorter lead times, a faster time-to-market and a high level of preparedness for integrated development should be met. </div> <div>“We agreed to focus on virtual development for manufacturing industry,” Söderberg explains.</div> <div>The centre was named the Wingquist Laboratory after the man who discovered the spherical roller bearing and founded SKF, Sven Wingquist. </div> <div><br /></div> <div><b><img src="/SiteCollectionImages/Centrum/Wingquist%20laboratory/690x-828_industri-forskningspartners.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px 10px;width:395px;height:474px" /><br />Close collaboration with industry</b></div> <div>The essence of the Wingquist Laboratory’s research is close collaboration with industry. Today the laboratory has nine industrial partners. Volvo Cars, AB Volvo and GKN (previously Volvo Aero) have been involved from the outset. Other industrial partners are Scania, Sandvik, Ikea, Saab, IPS and RD&amp;T Technology. Initially Söderberg and his colleagues put a lot of work into talking to industry about their needs.</div> <div>“They thought it was hard to grasp what Chalmers could offer. They got a bit here and there from various departments but there was no single entry point to Chalmers,” he says. “Today the Wingquist Laboratory is an arena where Swedish industry can collaborate with Chalmers in strategic areas for product realisation.”</div> <div><br /></div> <div><b>VINN Excellence Centre</b></div> <div>At about the same time as the Wingquist Laboratory was founded, a rumour went round about a future call for proposals via SSF (the Swedish Foundation for Strategic Research). Söderberg and his team, Johan S Carlson, Bengt Lennartson and Hans Johannesson, did some thorough preparatory work.</div> <div>“The call for proposals was for a total of SEK 70 million,” he says. “We succeeded in getting all three projects approved and managed to secure SEK 28 million, despite stiff competition.”</div> <div>Then, in 2004, when the first call for proposals came for Vinnova’s competence centre, the Wingquist Laboratory could showcase the successful strategy used on the projects and the benefits the centre provided. Out of 160 applicants, the Wingquist Laboratory was selected as one of 15 VINN Excellence Centres and an important milestone had been attained.</div> <div>The Wingquist Laboratory’s time in VINN Excellence (Vinnova’s research programme) extended over a ten-year period with steady funding and recurring evaluations. Research was conducted on three themes: Platform-based Development, Smart Assembly and Perceived Quality. </div> <div>“The evaluations were quite tough, but it strengthened us both scientifically and industrially,” Söderberg says. </div> <div><br /></div> <div><b>Interlinked methodology</b></div> <div>A successful model based on some key interlinked aspects was used from the outset (below):</div> <div>In order to launch a project in Wingquist there had to be a scientific challenge and an industrial need. “If these match up, we launch a project,” Söderberg says. “A project is normally concluded with a demonstrator, in other words a form of prototype, modified working method or industrial evaluation. In the Product and Use phase the results are implemented in industry, for instance through customer-specific solutions and training.</div> <div>“The fact that we as researchers see industry’s needs and develop constructive solutions together with the companies is only one of the strengths we can demonstrate. But we learn a great deal though collaboration and ensuring that our expertise and industry’s needs are matched up.” </div> <div><img src="/SiteCollectionImages/Centrum/Wingquist%20laboratory/690x390_Research%20implementation%20model.jpg" alt="" style="margin:5px" /><br /><br /><b style="background-color:initial">Competing companies share knowledge</b><br /></div> <div>The fact that they compete in their everyday operations is not something that has prevented Scania and AB Volvo from participating in the centre.</div> <div>“AB Volvo has its headquarters in Gothenburg and is a very obvious partner. Being able to include Scania later on, is something we are proud of. We see it as proof that we are developing things that are of great benefit to both of them. Both companies now use the RD&amp;T and IPS software which we commercialised.” </div> <div>The research has primarily benefited the motor industry, but more recently several companies have joined the centre, including IKEA. Söderberg explains: </div> <div>“We have a joint project on geometry assurance, in other words getting all the parts to fit together. Regardless of whether it’s an aircraft engine or a Billy bookcase to be assembled, the parts must fit together.</div> <div>“You come across these problems everywhere and the technology can be applied to many different types of products. Since the motor industry is highly competitive, it has been quicker to take interest in this research area. But we’re seeing increased interest from more sectors now,” he says.</div> <div><br /></div> <div><b>Global breakthrough</b></div> <div>Over the years several software applications have been further developed in the Wingquist Laboratory. Two of them have been commercialised. Since Chalmers does not develop and sell commercial software, a company, RD&amp;T Technology (simulation for geometry assurance) was founded, which sold its first licence to Volvo Cars back in 1998. IPS (Industrial Path Solutions) is another software application that was commercialised in 2004.</div> <div><br /></div> <div>“Work done in the spin-off companies falls outside the Wingquist Laboratory and does not directly provide scientific added value. However, the software takes the research out to the factory floor where it provides benefits and is utilised by thousands of users globally in large companies. This is also an important mechanism for finding out what works and what is needed next.”</div> <div><br /></div> <div><b>Satisfaction from running a centre</b></div> <div>The Wingquist Laboratory has delivered research of a recognised high quality and has produced 770 scientific publications since its inception. But Söderberg is most proud of the fact that the research is put to use in industry. </div> <div>“I’m motivated by developing something that is ‘for real’ and used industrially – by putting an idea into practice! My personal objective has always been to ensure that there’s ultimately a customer that wants what we offer.” </div> <div>“I wanted to create diversity when I built our team: to find people who complemented one another and could work together. Essentially you have to have similar core values. But you have to give everyone the chance to shine in their own area, while ensuring they contribute to the project as a whole,” he says.  </div> <div><br /></div> <div><b>Industrial needs keep evolving</b></div> <div>Platform technology, systems, product development, geometry assurance, motion planning for robots and automation are such key areas for industry that they are still relevant research areas. But companies are now asking for more and more automation and for the support of digital tools for various types of optimisation, analysis and visualisation. </div> <div>Söderberg says: “They also want digital information flows, brought from earlier development phases, to be taken throughout the entire chain. They are also asking for the aftermarket, maintenance and so on to be taken care of in the future.” He continues:</div> <div>“Many are also looking for the real-time adjustment and optimisation of production. It can be compared to a control system in which digital twins deal with the different mechanical and physical phenomena and variations that arise in real life.” </div> <div><br /></div> <div><b>Smart and environmentally sustainable factories</b></div> <div>There is an example of this in the SSF project Smart Assembly 4.0 which has a vision of the self-compensating factory.</div> <div>“This may involve matching up the right bits, adjusting fixtures and equipment and choosing the right sequence in spot welding, for example,” he explains. “Our methods can already reduce variation by an additional 50%. Apart from the financial return, it’s also more environmentally sustainable, since it reduces both waste and the use of materials.”</div> <div><br /></div> <div><b>Continued contribution to digitalisation</b></div> <div>Söderberg thinks that this is only the start and that the Wingquist Laboratory will continue to contribute to industry’s digitalisation, both in terms of the flow of information and the relevant engineering activities, towards a more or less automated process.</div> <div>“Over our 20 years of existence we have continuously evaluated ourselves to ensure that our research is relevant and is at the cutting edge. This is crucial in order to deliver peak performance academically while continuing to be relevant to industry,” he says. “And, hopefully we can continue to do so for at least another 20 years,” concludes Söderberg with a smile.</div> <div><br /></div> <div><br /></div> <div><a href="https://www.linkedin.com/company/wingquist-laboratory/?viewAsMember=true" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Follow the Wingquist Laboratory on Linkedin</a></div> <div><a href="https://twitter.com/WingquistLab" title="link to twitter account" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Follow Wingquist Laboratory on Twitter​</a></div> <div><br /></div> <div><br /></div> ​Thu, 19 Nov 2020 00:00:00 +0100https://www.chalmers.se/en/departments/ims/news/Pages/What-will-product-development-look-like-in-2040.aspxhttps://www.chalmers.se/en/departments/ims/news/Pages/What-will-product-development-look-like-in-2040.aspxWhat will product development look like in 2040?<p><b>​What will product development look like in 2040, and what part will the engineer play? In a report, authored by researchers Prof Ola Isakson from Chalmers and Prof Claudia Eckert from the Open University, over twenty representatives from leading companies and academia give their view on the future of product development.</b></p><div>​Even though new technology is often hyped up, there are clearly visible trends - both in society and technology - that will change the way products are developed, manufactured and consumed. The report <a href="https://www.designsociety.org/publication/43268/Product+Development+2040">Product development in 2040</a> is based on interviews and a workshop with experienced European engineers across Europe.</div> <div> </div> <div>Companies will become solution providers rather than manufacturers. Greater emphasis will lie on integrated systems where products can fulfil many needs. A car battery can for example be used for energy storage, but have the car and battery been designed to be used in this way? Modularization will play an important role to meet the needs of different applications and users. Digitalization will permeate every part of our lives and as products are becoming more connected a systems approach becomes even more important. Products will be to some extent cyber-physical systems based on an open architecture, which enables and requires both continuous product development. The means of design will shift significantly, in particular when considering how technological aids can be utilized. </div> <div><br /> </div> <div> </div> <h3 class="chalmersElement-H3">Who should read this report and why?</h3> <div>—  We can see that many of technological trends now are coming together. For the industry it is important to be aware of how these likely changes play out in the long run so that they can use the full potential and adapt their recruiting and business models. As a researcher it is important to be able to develop relevant tools and methods, and educators must be ready to put the necessary skills in place. Digital literacy will become a key factor with enormous importance, and I fear that there will be a competence shortage in this area, says Claudia Eckert.</div> <div> <img alt="Product development 2040" src="/SiteCollectionImages/Institutioner/IMS/Produktutveckling/Figur%209.jpg" style="margin:5px" /><br /><em>Complementary dimensions of future product development</em></div> <div><em></em><br /> </div> <h3 class="chalmersElement-H3">What will be the major changes in product development?</h3> <div>—  It’s not about the development of one or two new groundbreaking technologies. It’s about the integration of many different technologies into a coherent system, and designers will be in the focus to make this happen, says Ola Isaksson.</div> <div> </div> <div>—  The report covers many aspects of product development, but I would like to mention how additive manufacturing will probably break up the way supply chain is working today. There will also be a mixture of modern and old systems that are being kept alive because we don’t have the resources to replace them due to environmental reasons, says Claudia Eckert.</div> <div> </div> <div>—  There are evidence and incentives for a shift from linear to circular economy. Governments stimulate this change and the market behavior expect these changes and seek to satisfy and maturing the new technologies. The exact pace of this shift will depend on the pressure from society and companies’ ability to adapt into new business models, says Ola Isaksson. </div> <div> </div> <h3 class="chalmersElement-H3">What will the engineering profession look like in 2040?</h3> <div>—  We can see that there is a major trend of diminishing boundaries between the engineering disciplines, and a greater need for mathematical and statistical skills. Generalists are more likely to stay within the same company while specialist expertise is bought on demand, says Claudia. <br /></div> <div> </div> <div>—  There will be a need for both generalists and specialists, but engineers must be better systems thinkers. I think that the key question is how we can use deep specialist knowledge to create an overall effect, says Ola. </div> <div><div> </div> <h2 class="chalmersElement-H2">​​Read the full report</h2></div> <div> <div>The report can be downloaded here:<a href="https://www.designsociety.org/publication/43268/Product+Development+2040"> <br /></a></div> <div><a href="https://www.designsociety.org/publication/43268/Product+Development+2040">https://www.designsociety.org/publication/43268/Product+Development+2040</a><br /></div></div> <div><h3 class="chalmersElement-H3">The authors</h3> <div><a href="/en/Staff/Pages/iola.aspx">Ola Isaksson</a> is professor in Product Development and leader of the Systems Engineering Design research group at Chalmers University of Technology.  <br /></div> <div> <br /></div> <div><a href="http://www.open.ac.uk/people/cme8">Claudia Eckert</a> has been Professor of Design at the Open </div> <div>University since 2013.</div> <div><div>  </div> <h2 class="chalmersElement-H2">Funding and support</h2></div> <div> <div>This research was supported by a project funded by eSTEeM – The OU centre for STEM pedagogy, Project Reference 18E-CE-EI-01’ and Chalmers University of Technology via the Area of Advance Production.</div> <div><img alt="Funding and support" src="/SiteCollectionImages/Institutioner/IMS/Produktutveckling/Funding%20and%20support.JPG" style="margin:5px" /><br /><br />Published by: The Design Society, Glasgow, United Kingdom<br /></div></div></div> <div><img class="chalmersPosition-FloatLeft" alt="Design society" src="/SiteCollectionImages/Institutioner/IMS/Produktutveckling/designsocietylogo_web.jpg" style="margin:5px;width:265px;height:80px" /><br /><br /><br /> </div> <div> </div> ​​Tue, 29 Sep 2020 00:00:00 +0200https://www.chalmers.se/en/departments/ims/news/Pages/Systematic-Analysis.aspxhttps://www.chalmers.se/en/departments/ims/news/Pages/Systematic-Analysis.aspxSystematic Analysis of Engineering Change Request Data<p><b>Ívar Örn Arnarsson​, Doctoral student at Product Development IMS, defends his doctoral thesis &quot;Systematic Analysis of Engineering Change Request Data - Applying Data Mining Tools to Gain New Fact-Based Insights​&quot;.</b></p><div><span style="background-color:initial"><img src="/SiteCollectionImages/Institutioner/IMS/Övriga/div%20nyheter%20o%20kalender/Ívar%20Örn%20Arnarsson%20200x218.png" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br />Ívar will defend the thesis (online) on May 29, 13:00.

They driver for a change can be e.g. related to quality, safety, changes in external circumstances or regulation. These engineering changes often referred as Engineering Change Requests (ECRs) are largely generated through product development projects and are often stored in database while worked and later for some form of knowledge management purpose. </div> <div>Despite ECR being captured and stored it is often cumbersome for product developers to identify historical ECRs due to the vast amount of them. Historical ECRs might contain valuable knowledge relevant to a current design and it is often wondered if the ECR content might be analyzed in a new way insightful way. The content of ECR data must contain information permitting identification of the types of errors and changes made, including part title, part name, part number, problem description, root cause, solution and test results. </div> <div>This thesis primarily focuses on ECR data in combination with three components necessary to perform data mining and data analytics: exploring and collecting ECR data, collecting domain knowledge about ECR information needs, and applying mathematical tools for solution design and testing. </div> <div>Results show a list of engineering information needs related to ECRs, examples of visualizations based on unstructured data, industrial case study where complex product development processes are modeled using the Markov chain Design Structure Matrix, and studies that investigate how advanced searches based on natural language processing techniques and clustering within engineering databases.</div> <div><br /></div> <a href="https://research.chalmers.se/en/person/?cid=varo" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" /></a><a href="https://research.chalmers.se/en/person/?cid=varo" target="_blank">Read more</a><br /><a href="https://www.linkedin.com/in/ivararnarsson/" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />​Ívar Örn Arnarsson on Linkedin​</a></div></div></div></div> <div><a href="https://chalmers.zoom.us/j/63685389250" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Zoom link​</a></div>Fri, 08 May 2020 00:00:00 +0200https://www.chalmers.se/en/areas-of-advance/production/news/Pages/Looking-back-at-2019.aspxhttps://www.chalmers.se/en/areas-of-advance/production/news/Pages/Looking-back-at-2019.aspxHighlights from 2019<p><b>Two new large EU-projects and a strategic partnership with Ikea.

Congratulations to Maria Siiskonen, who was awarded a grant of SEK 50,000 from the Chalmers Foundation and Göran Wallberg&#39;s Memorial Fund in 2019, which will give funding for a four-month stay in Copenhagen, Denmark.</b></p><br /><div>
The Chalmers alum Göran Wallberg (VV-45) generously donated 2 million with the aim of helping students and younger researchers to gain international experience during their studies. The grant covers the areas of ICT (Information and Communication Technology), Production Technology and Environmental Technology.
</div> <div>&quot;It's a very nice Christmas present,&quot; says Maria Siiskonen, PhD student at the Department of Industrial and Materials Science, Chalmers. “I will use the grant for a research stay at the Technical University of Denmark, DTU, to learn more about adaptable manufacturing systems for personalized medicines.”</div> <div><br /></div> <div><strong>
Looking for solutions
</strong></div> <div>Maria Siiskonen's previous research has focused on product design and how different functionalities can be incorporated into medicines, for example in tablets. It makes it possible to adapt the medicine to the needs of the individual patient and thus optimize patients' treatments against a number of different diseases. 
</div> <div>A consequence from product customization is the accelerating number of product variants and previous studies indicate that current pharmaceutical production systems are not flexible enough to enable production of customized product in an economically feasible manner.
 </div> <div>“I want to take a closer look at how the production systems for individualized medicines to find how they should be designed, both from an economic and sustainable perspective. My focus will be on the adaptability and flexibility of the systems to meet the demand for patient-adapted product variants.”

 </div> <div><br /></div> <div><strong>Strong research at DTU attracts
</strong></div> <div>Maria explains that DTU's research group has a good reputation in the research area, in terms of the field of product customization and strategic approaches to product portfolio design.</div> <div>“Being here for a couple of months, will give me excellent opportunities to get a first-hand insight into their methods, discover new tools and hopefully get optimized product development methods to bring home with me. I think this will be an excellent opportunity to develop as a researcher”, concludes Maria.

A Novel Framework and Evaluation Methodology.&quot; on February 6, 2020. Opponent: Prof. Thomas J. Howard, Centre for Technology Entrepreneurship, Technical University of Denmark, Denmark Examiner: Prof. Rikard Söderberg IMS ​​</b></p><strong>Popular description</strong><div><div><div>Average consumer sees a car’s quality as a fancy mixture of a reliability, performance, design, aesthetics, and own previous experiences, unlike as a combination of mechanical parts, software pieces, advanced materials, cutting-edge manufacturing processes, with technical knowledge, skills and high production volumes – all ingredients involved into the modern car creation. Quite often, “humans do not see and act on the physical qualities of things, but on what they mean to them.” Closing the door of a Mercedes-Benz S-Class limousine produces signature sound with a vault-like thunk, making us react by generating multisensory images within ourselves. Handling certain premium quality wood panels gives a more sophisticated tactile impression than with a cheap plastic. The first olfaction, when entering a new Cadillac vehicle, creates a feeling of luxury, very different from that in a used car sold by a nearby car dealer shop.</div> <div><br /></div> <div>As one can see, understanding human’s perception of quality is a big challenge for researchers and practitioners. “What product features require the most attention for successful car design?” – The question engineers and designers need to answer under the pressure of shrinking product development time, a boost of available technologies, and financial limitations. Not to mention, the answer is expected to be given in numbers to sustain a fierce competition in the automotive industry. In that case, if a car manufacturing company wants to secure the ability to meet the consumer’s expectations, there is a need to control the perceived quality. Easy to say, hard to do.</div> <div><br /></div> <div>Perceived quality is a complex, multifaceted adaptive system - a system where a human is the main agent. Therefore, many perceived quality attributes are difficult to define explicitly. This fact creates a “wicked problem” for any car manufacturer. </div> <div><br /></div> <div>To confront the problem, we need to name it. For this reason, the perceived quality in engineering science has been defined and structured as the Perceived Quality Framework (PQF), in the form of a two-dimensional typology: (i) Technical Perceived Quality (TPQ), encompassing intrinsic attributes - everything that is part of a product and can be controlled by design and/or engineering specifications; (ii) Value-based Perceived Quality (VPQ), including extrinsic attributes - such as brand image, brand heritage, affective consumer judgments, design, hedonic or social values, the impact from other global attributes, advertising, and marketing promotion techniques. </div> <div><br /></div> <div>The perceived quality domain is a place where the product meaning, form, sensorial properties, and their execution intersect with human experience. Such an experience is driven by the interplay between product quality and its context. The ultimate goal is to find the trade-off between perceived quality elements. This resulted in the creation of the Perceived Quality Attributes Importance Ranking (PQAIR) method. The novel methodology was created to assist the engineer or designer in the decision-making process regarding the relative importance of perceived quality attributes for the final product. The PQAIR method illuminates the interplay between technical characteristics of the product and customer perceptions. The successful implementation of the method can help find an answer to the question, “What makes you, as a consumer, to fall in love with a specific car?” This is, after all, a very “expensive” question. Billion-dollar decisions in the automotive industry often rely on predictions and assumptions about how a customer will perceive and evaluate such a complex product as a car. The ontology of PQF and its principles shifts the perceived quality evaluation processes towards the objective and reproducible side. </div></div> <div><br /></div> <div></div> <div>Keywords: perceived quality, automotive, product development, product quality, premium, luxury,</div> <div>knowledge management, design, aesthetics, engineering;</div></div> <div><br /></div> <div><a href="https://research.chalmers.se/en/publication/514275"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read the thesis</a></div> <div><a href="https://www.linkedin.com/in/kostas-stylidis/"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Kostas Stylidis on LinkedIn</a></div> <div><br /></div> <div><div><strong>Public defence</strong></div> <div>2020-02-06 09:00</div> <div>Virtual Development Laboratory (VDL), Chalmers Tvärgata 4C, Johanneberg Campus, Gothenburg</div></div> <div><br /></div> ​Wed, 15 Jan 2020 00:00:00 +0100https://www.chalmers.se/en/areas-of-advance/production/news/Pages/ICED-conference-to-Chalmers.aspxhttps://www.chalmers.se/en/areas-of-advance/production/news/Pages/ICED-conference-to-Chalmers.aspx​World-leading product development conference to Chalmers<p><b>​In August 2021, Chalmers University of Technology will host the world&#39;s largest scientific conference in product development, the 2021 International Conference of Engineering Design (ICED21).</b></p><div><span style="background-color:initial">The first ICED conference took place in Rome in 1983.

Range and Supply becomes new strategic partner for Chalmers<p><b>A new five-year agreement marks the start of a closer collaboration between Ikea Range and Supply  and Chalmers, in research, competence development and innovation. One of the goals is increased sustainability, primarily through utilising opportunities in recycling, new materials and new technologies, including digitalisation.​</b></p>​<img src="/SiteCollectionImages/Areas%20of%20Advance/Production/300x384-ikeaflaggor.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px 15px;width:275px;height:354px" /><span style="background-color:initial">The agreement lays the groundwork for broad collaboration within research, which is now being built up gradually. Chalmers and Ikea Ikea both have the opportunity to utilise each other’s physical environments for research and innovation. Chalmers will also continue to provide training for Ikea co-workers and give them opportunities for closer contact with students.</span><div><br />“I am really happy about this and see many exciting opportunities. Not least, that we can mobilise research from various subject areas around the challenges Ikea is facing. This is a long-term and broad agreement, like those we have in place already with some 15 other companies. It clearly indicates that Ikea should be perceived as a company building on increasing engineering capabilities, with good career opportunities for students from many different programmes,” says Stefan Bengtsson, Chalmers President and CEO.</div> <div><br /></div> <div>From Chalmers' side, the Production Area of Advance acts as the host for the collaboration, and the contact for both Ikea and Chalmers. Managing the planet's resources through production, and utilising those resources in as long-sighted and smart a way as possible, is of great importance for Ikea.</div> <div>“We want to disconnect from the old saying that sustainability has to cost more. If we are really to turn society in the right direction, we must ensure that sustainable solutions are implemented and produced at low cost, so they can be available to many people,” says Jeanette Skjelmose, Deputy Managing Director of Ikea Range and Supply.</div> <div>Increased utilisation of big data, machine learning, and AI are areas that can be further discussed, as well as digital tools in product development. Other areas of interest are bio-based plastics and recycling of residual production material.</div> <div>“I really look forward to working with Chalmers. I think we can learn from each other and be able to explore and develop new opportunities within new materials and technologies. The possibility to improve the competence of our employees and attract new talents through our collaboration is also an expectation,” says Jeanette Skjelmose.​</div> <div></div> <div><div><em><br /></em></div> <div><em>Text: Christian Borg / Carina Schultz</em></div> <div><em>Photos: Carina Schultz</em></div></div> <div><br /></div> <div><img src="/SiteCollectionImages/Areas%20of%20Advance/Production/750x440-arbetsgrupp-ikea.jpg" alt="" style="margin:5px;width:680px;height:398px" /><br /><br /></div> <div><em>On site at Älmhult, from left: Ruth Woie Svensson, Anders Wennberg, Susanne Waidzunas (Ikea), Malin Cullin (Ikea), Ulrika Lundqvist, Stefan Bengtsson, Jeanette Skjelmose (Ikea), Lars Nyborg, Ulrika Rosling (Ikea) and Na Lin (Ikea).</em><br /></div> <div><br /></div> ​Wed, 06 Mar 2019 00:00:00 +0100https://www.chalmers.se/en/departments/e2/news/Pages/Smoother-movements-reduce-power-peaks.aspxhttps://www.chalmers.se/en/departments/e2/news/Pages/Smoother-movements-reduce-power-peaks.aspxSmoother movements reduce power peaks<p><b>​By programming industrial robots to operate more smoothly, and thus avoiding heavy accelerations and decelerations, energy consumption as well as power peaks can be significantly reduced. Based on these results, researchers are now taking a step further to investigate how other production equipment containing moving devices can be optimized.</b></p>​D<span style="background-color:initial">esigning optimal processes, while considering energy and environmental aspects, is becoming an increasingly important concern for the manufacturing industry. In the long run, it provides a competitive edge in terms of reduced production costs and a stronger sustainability profile.</span><div><br /></div> <div>Since several years, the research group Automation at Chalmers University of Technology has collaborated with the automotive industry to reduce energy consumption in robotic systems used in manufacturing processes. The industrial robots are energy-intensive. For example, in automotive bodywork factories the robots' consumption amounts to about half of the total energy used in production.<img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Mjukare%20rörelser%20kapar%20effekttoppar/Bengt-Lennartsson_250px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><br /><br /></div> <div><div><strong>Lower energy demand and no production loss</strong></div> <div>”Our results show that the energy consumption can be reduced by 20-25 percent when industrial robots operate with smoother movements and avoid unnecessary starts and stops”, says Bengt Lennartson, Professor of Automation at the Department of Electrical Engineering. “And this without reducing the pace of production.”</div> <div><br /></div> <div>The reduction is even greater when it comes to the robots´ power demands – the power peaks can be decreased by as much as 60 percent. As the powerconsuming accelerations are greatly reduced, in favour of a more balanced mode of driving, not as large momentary power demands occur. This also has a positive impact on the life-span of the components.</div> <div><br /></div> <div>“The power demand being reduced to such high extent is a positive side effect of the energy saving we initially intended to achieve. So far, the power balance in the Swedish energy system has been good, but in the future, if the country is facing a situation where power shortage may occur, it will be expensive for industries whose electricity consumption is characterized by high power peaks.”</div> <div><br /></div> <div><strong>Bringing the method forward</strong></div> <div>“Our method for optimizing the robots has proved to be both simple and efficient,” says Bengt Lennartson. “The optimization never changes the robot’s operation path, only the speed and sequence. We collect data from the real robot and process it in an optimization program. The result is improved control instructions that are directly fed back to the robot.”</div> <div><br /></div> <div>The research group has now started to apply their method in other fields of engineering as well, where there are moving and energy-intensive systems. This could include automated guided vehicles, conveyor systems and numerically controlled machining tools.</div> <div><br /></div> <div><strong>The production system of the future</strong></div> <div>The research on energy efficiency conducted by the Automation research group is a good example of computer-driven optimization methods. This type of optimization, combined with artificial intelligence, AI, is about to make its entry into industrial production to form what is known as Intelligent Manufacturing. It is about smart machines and connected manufacturing systems that interact and communicate with each other.</div> <div><br /></div> <div>“Not least in China, there is a great interest in intelligent and sustainable production systems,” says Bengt Lennartson, who recently has participated as invited speaker in several research conferences on this topic. “Sweden is often mentioned as a good example of how sustainable and energy efficient manufacturing systems can be designed, and I agree that it really is our strength.</div></div> <div><br /></div> <div>Text: Yvonne Jonsson</div> <div>Photo: Malin Ulfvarson and Oscar Mattsson</div> <div><br /></div> <div><div><strong>More about the research</strong></div> <div><a href="/en/departments/e2/news/Pages/Smooth-robot-movements-reduce-energy.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Smooth robot movements reduce energy consumption by up to 40 percent</a></div> <div><a href="/en/projects/Pages/Automation-and-Robotics-for-EUropean-Sustainabile-manufacturing.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Automation and Robotics for EUropean Sustainabile manufacturing (AREUS</a>)</div> <div><a href="/en/projects/Pages/Sustainable-motions---SmoothIT.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Sustainable motions, SmoothIT</a></div> <div><a href="/en/projects/Pages/ITEA3Q-Smart-Prognos-av-EnergianvQndning-med-resursfQrdelningQ.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Smart prognos av energianvändning med resursfördelning, SPEAR​</a></div> <div><br /></div> <div><strong>For more information, please contact:</strong></div> <div>Bengt Lennartson, Professor of Automation, Head of Division System and Control, Department of Electrical Engineering, Chalmers University of Technology, Sweden</div> <div>+46 31-772 37 22,<a href="mailto:%20bengt.lennartson@chalmers.se"> bengt.lennartson@chalmers.se</a></div></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Mjukare%20rörelser%20kapar%20effekttoppar/Energy-robot_power_consumption_500px.jpg" class="chalmersPosition-FloatLeft" alt="Power consumption industrial robot" style="margin:5px" /><br /><br /><br /></div> <div><span style="background-color:initial">​</span><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><br /></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">Reducing power peaks through minimizing accelerations in the robot movements.</span><span style="background-color:initial">​</span><br /></div>Thu, 24 Jan 2019 07:00:00 +0100https://www.chalmers.se/en/centres/wingquist/news/Pages/The-future-of-research-in-design-processes---report.aspxhttps://www.chalmers.se/en/centres/wingquist/news/Pages/The-future-of-research-in-design-processes---report.aspxThe future of research in design processes -

For example, chemical propulsion (used to propel the space shuttle in 1969) is too costly and has the big disadvantage to consume a lot of propellant to reach long distances. Electric propulsion represents a promising alternative, since we can use much less propellant. Furthermore, we can make use of the only energy source available in the solar system: the sun.    </div> <div><br /></div> <div>At the same time, the space industry is in the middle of a transition. New actors such as <a href="http://www.oneweb.world/">OneWeb</a> are planning to launch thousands of satellites around the earth to provide low cost - yet fast - internet to the whole world.

There are major societal challenges where research collaboration with industry is important. Since Sweden has the ambition to become the world's first fossil-free welfare state, it requires development in many areas. The research on lightweight materials and lower fuel consumption is an example.”<br /><br />What issues are relevant now, given the situation in the outside world?
<br /><br />&quot;The worst threat right now is whether we enter a trade war. Sweden is very dependent on exports and about half of our GDP come from exports. In addition, 70% of the export go to the EU's internal market, so when Britain leaves, it becomes an extremely difficult challenge for Sweden. For example, the UK is our largest exporting country for services. And cooperation between universities and industries will also be complicated.”

<br /><br />&quot;What I've heard about today has been incredibly exciting. I hope I get the opportunity to visit Chalmers again, Ann Linde concludes.<br /><br /><em>Text and photo: Carina Schultz</em><br />Thu, 06 Sep 2018 00:00:00 +0200https://www.chalmers.se/en/departments/ims/news/Pages/rikard-soderberg-fellow-cirp.aspxhttps://www.chalmers.se/en/departments/ims/news/Pages/rikard-soderberg-fellow-cirp.aspxProfessor honorable appointed to CIRP Fellow<p><b>​Professor Rikard Söderberg has been appointed as Fellow of the International Academy of Production Engineering, CIRP.

It can have different purposes and is therefore supplied with various real-time data. The digital twin is connected wirelessly to databases and physical devices and is predicted to be common in future production systems.</div> <div>At the same time, the development of simulation models for geometry assurance has been going<span><span></span></span> on for many years. It has gone from simpler simulation where details have been assumed rigid, to more advanced finite element (FEM) based simulations.</div> <div>-    The work of recent years has been aimed at driving simulation models for non-rigid geometry as digital twins in the future. It could mean an ability to control both the production process and product development in a more efficient way, says Professor Söderberg.<br /></div> <h5 class="chalmersElement-H5">Faster algoritms demands</h5> <p class="chalmersElement-P">However, in order to fully exploit the simulation models for geometry assurance as digital twins - both in production and in early stages of development - it is necessary to develop further. The project is therefore divided into three parts: <span></span></p> <div>The first part project focuses on better material models and finding faster algorithms for real-time use. This means refinement of the digital twin to handle more advanced material properties as multi-material solutions, i.e. solutions in which different materials are used in the same subassembly or the same component. Residual stresses, depending, for example welding details, also affects the geometrical deviation and variation and must therefore also be included in the simulations.</div> <div>-    This means more complex and demanding calculations. Therefore, we need to develop high-speed algorithms for real-time use, says Söderberg.<br /></div> <div><h5 class="chalmersElement-H5">Visualization necessary for decisionmaking</h5> <div>To use the digital twin as a decision tool, you need to visualize the variation as realistic as possible. Therefore, in the second part of the project, you enhance the simulation models with Raytracing, 3D scanning / point clouds and digital environments.</div></div> <div>Raytracing means increased realism when visualizing manufacturing variation and can be used to support decision-making in the early stages. Scanning results as point clouds are currently used to measure and verify components and products with great accuracy. Point clouds can be used to compare variations in batch details, but the method requires faster and more efficient algorithms due to the large amount of data.</div> <div>Finally, there is a need for models of digital environments visualizing the impact of manufacturing variations on perceived quality.<br /></div> <div>-    To effectively visualize geometric variation, models are required, as well as design and data to be combined into scenarios that then are evaluated. If we manage to automatically generate those models, we would significantly rationalize the geometry insurance process. We benefit greatly from the research on visual evaluation conducted by the department within the research area Percieved Quality, says Rikard Söderberg.</div> <div>In the third and final subproject, a preliminary study of a digital information flow, a so-called “Digital Thread”, is being planned. It will predict how the future digital geometry assurance process might look.<br /></div> <div><h5 class="chalmersElement-H5">Industrial co-operation and advanced mathematics</h5> <div>The DigiGeo project, which started at the beginning of the year, extends over two years and brings together academics, research centers and industry. </div></div> <div>-    We carry out this project in cooperation with Fraunhofer Chalmers Center, who has the required advanced competence in industrial mathematics for the development of algorithms, says Söderberg, and continues:</div> <div>-    The project would not be possible without collaboration with industry partners such as Volvo Cars, IKEA, GKN, VA Automotive and RD&amp;T Technology.<br /><br /><em>Text: Carina Schultz</em><br /><em>Photo: Shutterstock (large image) and Anna-Lena Lundqvist (portrait) </em></div> <div> <br /></div> <div><strong><a href="https://research.chalmers.se/en/project/?id=8173" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Digital Twin for Geometry Assured Production (DigiGeo)</a></strong></div> <div><strong>Project leader: </strong>Professor Rikard Söderberg, Department of Industrial and Materials Sciences</div> <div><strong>Project time: </strong>2018-2019</div> <div><strong>Financing: </strong>Vinnova / 5 MSEK<br /><br /><a href="/en/departments/ims/research/product-development/Pages/default.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read more about the Division of Product Development</a><br /><br /><br /></div> <div> </div> <div> </div>Mon, 21 May 2018 14:00:00 +0200
