Abstract [en]

The present study explores the adoption of electroencephalography andeye tracking to assess physiological differences between divergent and convergentthinking. In neuroscientifi c literature alpha power synchronization in the rightparietal lobe has been associated to top-down inhibition of task-irrelevant cognitiveprocesses occurring during divergent thinking, but fi ndings in oculometric studiesseem to suggest a bottom-up process operated by active visual-gating. In the presentstudy, 14 male engineering students performed an adaptation of the AlternativeUses task under two experimental conditions. During the task brainwaves andocular activity were collected using electroencephalography and eye tracking, butresults did not reach statistical signifi cance. Improvements in the experimentalsetting and analysis method to overcome similar problems are presented. Futurestudies should further delve into the infl uences on results of experimental settingsand of analysis methods to increase comparability among physiological studies.

Abstract [en]

Additive Manufacturing (AM), and more specifically Powder Bed Fusion, offers design freedom, functional integration, and cost efficient manufacturing of customised products. These design and manufacturing capabilities are relevant for the space industry with its characteristic low production volumes, high-performance products, pursuit for low weight, and a recent need for cost reduction due to increased market competition. At the same time, the space industry is characterised by products in harsh environments without room for failure, nor the possibility to repair broken parts in service. Product qualification is therefore an important part of the product development process in the space industry, with the purpose of showing that the product design and its manufacturing process fulfils the technical requirements. Qualification is a challenge for AM that currently exhibits a sensitivity in part mechanical properties based on geometry and build orientation, as well as a variability in process outcome. As with other manufacturing processes, design engineers have to take process capabilities into account during product design to render a manufacturable product (Design for AM), but also to achieve the right quality and function (Design for Excellence). Apart from manufacturability, product qualification has to be considered early in the product development process of AM parts. Given the lack of understanding of AM process characteristics, design engineers are in need of design supports to facilitate the qualification of critical AM parts. This paper presents a Design for Qualification process model for development of AM components in critical space systems. The model is proposed based on research performed in the space industry with several case companies.

Abstract [en]

Additive Manufacturing (AM) has the potential to remove boundaries that traditional manufacturing processes impose on engineering design work. The space industry pushes product development and technology to its edge, and there can be a lot to gain by introducing AM. However, the lack of established qualification procedures for AM parts has been highlighted, especially for critical components. While the space industry sees an advantage in AM due to expensive products in low volumes and long lead-times for traditional manufacturing processes (e.g. casting), it also acknowledges the issue of qualifying mission critical parts within its strict regulations. This paper focuses on the challenges with the qualification of AM in space applications. A qualitative study is presented where conclusions have been drawn from interviews within the aerospace industry. The results highlight important gaps that need to be understood before AM can be introduced in critical components, and gives insight into conventional component qualification.

Abstract [en]

Early involvement of production can on the one hand create products better adapted for realization, but on the other hand introduce the risk that incremental adjustments of existing operations and processes is favoured at the expense of more radical ones. The research reported in this paper aims to explore how innovative projectteams manage this paradox of early production involvement and innovativeness. Results show that a number of separation strategies at the micro level in the organization play an important role in practice.

Abstract [en]

Ideas and concepts are the carriers of innovation, which many regard as a critical source of competitive advantage. At the same time, an initial idea is untested and unrealized, i.e., it is always surrounded by a lack of knowledge. The purpose of this paper is to investigate how different types of ideas develop and interact with knowledge, by focusing on remediating activities performed by design teams. Results are based on a retrospective interview study involving respondents from eight projects, all selected for their high degree of innovativeness. The analysis emphasized two types of ideas (product ideas and concept ideas) and three spaces of design knowledge (the why-space, the what-space, and the how-space). The results reveal two possibilities: either the content of the knowledge space differs depending on the type of idea, or different knowledge spaces exist. Moreover, activities conducted to improve the idea have different characteristics depending on the type of idea. It is thus important to distinguish between different types of ideas and to choose corresponding mitigation activities to support idea development.

Abstract [en]

Additive Manufacturing (AM) is a fast developing manufacturing technology that brings many opportunities for the design teams at companies working with product development. One industry that has embraced this is aerospace, and more specifically within space applications (satellites and launchers). Although there are huge possibilities with this technology, there are also several challenges that need to be overcome. This paper is based on interviews, study visits and a state of the art review from the current literature. The focus of this work has been to map the opportunities and challenges with AM in space applications and to highlight the research gaps that have been found. There are few documents available that address AM and/or innovation within space applications. The results show that design for AM, as well as product and process qualification, are areas that need to be further investigated.

Abstract [en]

For students to develop independent learning strategies, it is essential to have anunderstanding of what it is they are aiming for. For this reason, every educational programme in Sweden has learning outcomes as stated by the Swedish Higher Education Authority.However, these are rather formal and sometimes described in a way that is not easy, either for teachers or for students, to implement in teaching and learning activities. A challenge is to both apply CDIO-standards and comply with the Swedish Higher Education Authority’s stated learning objectives. At the same time, we should uphold students’ motivation to develop their competences and teachers’ understanding of which teaching and learning activities are relevant, and how and what to assess in students’ learning to contribute to all of these approaches. The aim of this paper is to describe the development of a competence profile. The idea is primarily based on the Vitae Research Development Framework, but with inspiration from several other frameworks and approaches. The competence profile is designed to support students´ individual professional industrial design engineering competences. It allows the students themselves to map their knowledge, skills, experiences and qualities, and also provide support for teachers’ feedback and assessment. In other words,the student competence profile is used to describe what students are supposed to be able to do (prior to courses), what the learning activities are supposed to contribute to (during courses) and for formative and summative feedback of how well it has been done (during and after courses). It also allows a visualisation on how different courses contribute to the overall programme objectives.

Abstract [en]

Global cooperation is a reality for most engineering design teams today, and even though the core group is co-located, they are forced to cooperate with subcontractors or experts with complementary knowledge and skills. The design process can be seen as an integration of a technical, cognitive and social process, and such process is clearly multidisciplinary. This review presents research challenges and emerging directions for future research and focuses on interpersonal communication in collaborative design – small teams of interdisciplinary stakeholders who work jointly toward a common goal that would not otherwise be accomplished by the individual participants themselves.

Abstract [sv]

På nittiotalet, då jag utbildade mig till industridesigner på HDK vid Göteborgs Universitet, var det inte många som visste något om det yrket, de frågade ”... menar du kläder?”. Vilken skillnad jämfört med nu när alla verkar veta och tycka något om designade prylar och använder många olika digitala tjänster.Som nyanställd på ett konsultföretag upptäckte jag att inte heller i näringslivet var design speciellt känt. Jag fick ofta prata med kunderna om vilken möjlighet designtänkande kunde vara för dem och deras produkter. Det grundlade en övertygelse hos mig om behovet av strukturerade metoder och ett arbetssätt som kommunicerar väl med kunden. Jag ville arbeta mer med det så 2001 beslutade jag mig för att börja undervisa. Under fem år som lärare i industridesign på HDK och tio år vid Teknisk design på Chalmers har jag använt många böcker med olika inriktningar och möjlighet till fördjupning. Jag har saknat en bra översikt som studenterna kan komma tillbaka till i projekt och som de senare i yrkeslivet kan använda för att visa helheten för andra, tills jag blev inkopplad på den här boken. Det finns idag många olika utbildningar och yrkesvarianter av designers. Fler och fler upptäcker att design är något av det viktigaste som finns. Det påverkar ju oss dagligen, avgör om och när vi väljer något och hur vi använder det. Design är också, som du kommer att märka när du läser boken, mycket mera än bara sakerna vi ser. Ja egentligen kan allt som skapas och formuleras på något sätt vara designat. Men det är skillnad på design och design, ibland är den bara en fördyrande detalj eller uppsnyggning av något, ibland är den innovativ och tar hänsyn till själva användningen och användaren. Det svåraste för de som betraktar eller ska introduceras till design brukar vara förhållandet mellan det objektiva och det subjektiva - vad är sant för alla och vad är bara sant för en utvald grupp? Och vad är den viktigaste delen av design; är det tekniken, nyhetsvärdet, utseendet eller funktionen? Efter att ha sett tusentals projekt och lösningar är jag övertygad om att de lösningar som överlevt, och kommer att överleva längst, är designade av människor som förstått vilka som ska använda deras lösningar och hur användarens behov av form och funktion är. En optimal designlösning är olika för olika människor och olika situationer, när du kan hantera det har du kommit långt som designer. En vanlig missuppfattning om design är att det är något som fixas till i slutet eller att det är en rent konstnärlig process där man väntar på inspiration. Det bästa resultatet kommer när designtänkandet är strukturerat och finns med tidigt. Många av dagens produktsystem är svåra att förstå och använda. Här kan olika professioner hjälpas åt eftersom en av designerns viktigaste uppgift är att analysera och visualisera behov, gränser och innovationsmöjligheter för och tillsammans med andra. Därför behövs förståelse för designtänkande mer än någonsin inom många yrken, såväl tekniskt som socialt. Det är, som jag brukar säga till studenterna, enkelt att göra något svårt men svårt att göra något enkelt - det gäller att hitta essensen av någots existens. Det har varit mycket roligt att få vara en del i framtagandet av den här boken. Här finns en helhet som är sällsynt. Författarna har i Design:process och metod lagt mycket arbete och efterforskningar på att strukturera och ta fram en unik sammansättning av olika synsätt och metoder för alla som vill förstå designarbete och beprövade designverktyg som en helhet. Genom att studera och prova dessa kan den som läser få en korrekt start, bli mer kreativ, göra en bättre presentation av sitt eget designarbete eller förstå andra som arbetar med design. Det här är en bok som borde vara obligatorisk läsning för alla som handskas med utvecklingsprojekt.
