From Product to Dust: Looking at the Ways to Regenerate Value in Product Life Cycle
Authors: Menu Baptiste , Jenny Faucheu , Valérie Laforest , Jean-François Bassereau 
Published: July 2019

AbstractThe shift from linear to circular patterns is on the way and rise many questions. In the last ten years, reuse and upcycling are gaining more attention. Since reduce and reuse were describe as a priority by the European Union, some leading projects are unveiled in different countries. Scale and quality of those projects push the reuse issue out of the shadow, far from original prejudices who associate waste and reuse to « poverty » and « Do It Yourself ». Although Reuse emerge as a prominent question, the idea and boundaries of « what is reuse » appears to be blur and not clearly understood. This situation lead to general incomprehension, even for professionals. Reuse, repurpose, upcycling and recycling are usually considered to wear the same meaning despite a huge difference on what it implies.In this paper we will examine these different notions through a pedagogical case study. We will draw the different ways to regenerate value at all steps of product life cycle in a precise manner. This allows to better insight the meaning of those issues in the case of student design education. In the same time, it aims to be a tool for teaching sustainable design and waste management.
A Modeling Approach for Elastic Tolerance Simulation of the Body in White Hang-On Parts
Authors: Zheng Hanchen , Litwa Frank , Reese Benjamin , Li Chenyang , Bohn Martin , Paetzold Kristin 
Published: July 2019

AbstractComputer aided tolerancing (CAT) in the automobile industry is implemented by CAD tools. These tools analyze the manufacturability of complex assemblies with rigid single parts in an early stage to reduce the product development time and the cost for hardware prototypes. This paper proposes an approach to implement tolerance simulation for a compliant assembly, which includes manufacturing processes such as clinching, bolting and hemming by applying tolerance simulation tool. The fender- BIW system is simulated as a compliant–rigid system and the simulation model is applied to two production scenarios. The simulation results are compared with real measurement data, which demonstrates the efficacy of using simulation in early production as opposed to prototyping or other methods of design by showing the strong correlation between simulation results and as-built products.
MBSE-integrated Parametric Working Surfaces as part of a PLM Design Approach
Authors: Katzwinkel Tim , Löwer Manuel 
Published: July 2019

AbstractThis paper demonstrates a concept for a cross-domain strategy for the sustainable processing and dissemination of product information. Important functional product features are explicitly mapped as working surface information in different domain tools with the help of the contact channel method and are integrated using a model-based systems development approach. The approach uses established state of the art design tools and can be integrated into existing product development processes, knowledge based engineering concepts and product (system) lifecycle management strategies.
Doing it Right - Critical Success Factors for Design Thinking Implementation
Authors: De Paula Danielly , Dobrigkeit Franziska , Cormican Kathryn 
Published: July 2019

AbstractProficiency in design thinking (DT) can contribute to the success of many companies. Successful implementation of DT can be achieved by identifying its Critical Success Factors (CSFs). Critical success factors are items or actions that should be present in a particular project or situation in order to be successful. However, to date, there has not been any formal study on synthesizing the critical success factors for a successful DT implementation based on existing research. In light of this, the aim of this paper is to develop a conceptual framework that proposes factors that may play a role in influencing the success of the DT implementation. Based on best practices and protocols from thematic analysis, we analyzed and synthesized extant literature in order to recognize research topics from the selected papers and categorize them into specific themes to build a framework. This study significantly contributes to the body of knowledge related to DT by offering the first attempt to identify CSFs for DT implementation, which can allow companies to take required precautions to elude failures or problematic areas and be able to increase the success rate of implementing DT
Feature Engineering for Design Thinking Assessment
Authors: Arlitt Ryan , Khan Sumbul , Blessing Lucienne 
Published: July 2019

AbstractAs design and design thinking become increasingly important competencies for a modern workforce, the burden of assessing these fuzzy skills creates a scalability bottleneck. Toward addressing this need, this paper presents an exploratory study into a scalable computational approach for design thinking assessment. In this study, student responses to a variety of contextualized design questions – gathered both before and after participation in a design thinking training course – are analyzed. Specifically, a variety of text features are engineered, tested, and interpreted within a design thinking framework in order to identify specific markers of design thinking skill acquisition. Key findings of this work include identification of text features that may enable scalable measurement of (1) user-centric language and (2) design thinking concept acquisition. These results contribute toward the creation of computational tools to ease the burden of providing feedback about design thinking skills to a wide audience.
Semantic Measures for Enhancing Creativity in Design Education
Authors: Georgiev Georgi V. , Casakin Hernan 
Published: July 2019

AbstractAnalysing verbal data produced during the design activity is helpful to gain a better understanding of design creativity. To understand exchange of information in terms of creative outcomes, a semantic analysis approach was used to measure the semantic content of communications between students and teachers. The goal was to use this tool to analyse design conversations, and to investigate their relation to design creativity, assessed in terms of originality, usability, feasibility, aesthetics, elaboration, overall value and overall creativity. Abstraction, Polysemy, Information Content and Semantic Similarity were employed to explore 35 design conversations from the DTRS10 dataset. Main findings suggest that a significant relationship exists between Information Content and Originality, and between Information Content and Overall creativity of the produced design outcomes. Significant relations were also found between Abstraction, Polysemy, Information Content, and Feasibility, as well as between Semantic Similarity and Overall Value of the outcomes. Implications for the use of semantic measures for encouraging creativity in the design studio are discussed.
Roadmap to Consider Physiological and Psychological Aspects of User-product Interactions in Virtual Product Engineering
Authors: Wartzack Sandro , Schröppel Tina , Wolf Alexander , Miehling Jörg 
Published: July 2019

AbstractTo successfully facilitate user-centred design, a multitude of different aspects has to be considered, from purely physiological to psychological-emotional factors. The overall aim is to increase the customer satisfaction by enhancing the fit between products and their users in the respective context of use. Further virtualisation of user-centred design processes holds the potential to convey the concepts of frontloading and predictive engineering from classical product engineering. Our vision is to facilitate a comprehensive consideration of user-product interactions in virtual product engineering operationalised by the mission to develop methods and tools to assess and design user-product interactions according to physiological and psychological aspects. A variety of work has already been done to model musculoskeletal user groups, to configure, predict, simulate and optimise physical user-product interactions, to integrate such models into CAD or to map individual subjective values to product design. Nevertheless, there are still research areas to be addressed to enable a comprehensive implementation of the mentioned approach. These are discussed in the present contribution.
A Research through Design Framework from the Evaluation of a Meta-Design Platform for Open and Collaborative Design and Making Processes
Authors: Menichinelli Massimo 
Published: July 2019

AbstractThe democratisation of technologies, knowledge and activities have been changing the world of designers, blurring the boundaries between amateur and professional designers, especially within the connected phenomena of the Maker Movement and Indie Designers. Within this context, how can be collaborative design processes documented, analysed, managed, shared? This article investigates the role of meta-design digital tools for the facilitation of distributed systems of creative agents, formally trained and informal amateurs that collaboratively design and produce artefacts. It documents a research study organised for testing a digital meta-design platform with users and the researcher as meta-designer: the results provide insights for improving the platform but also for building a comprehensive research through design framework that connects meta-design research and practice for exploring the role and nature of meta-design and meta-designers in facilitating collaborative design processes starting from their description with digital ontologies.
Experimental Evaluation of a Debiasing Method for Analysis in Engineering Design
Authors: Nelius Thomas , Matthiesen Sven 
Published: July 2019

AbstractDuring analysis in engineering design, systematic thinking errors - so-called cognitive biases - can lead to inaccurate understanding of the design problem. With a simplified version of the Analysis of Competing Hypotheses - ACH method and a simplified decision matrix, the confirmation bias in particular can be minimized. To evaluate this method, it was taught to experienced design engineers and mechanical engineering students. During the experimental evaluation the participants analysed a real technical problem. The procedures and results were compared with a previously conducted study with the same task. The design engineers have not changed their approaches and could not further improve their analysis success. The students profited considerably from the training. They have mentioned twice as much supporting evidence and six times as much contradicting evidence through the training indicating a more extensive analysis. As a result, the students showed significantly fewer signs of confirmation bias than without training. The findings suggest that debiasing strategies should be introduced early in engineering design education.
Teaching and Learning Design Methods: Facing the Related Issues with TRIZ
Authors: Fiorineschi Lorenzo , Frillici Francesco Saverio , Rotini Federico 
Published: July 2019

AbstractDesign methods are claimed to support designers but, although they are largely taught in academia, their industrial uptake is still lacking. Many reasons have been identified about this flaw and some potential suggestions have been proposed and discussed in literature to overcome the problem. However, a further evidence is that although many students learn such methods from years, they partially or totally abandon the learned methods in their professional careers. This could partially explain the gap between academic and industrial diffusion of design methods. Literature provides suggestions for improving the learning experience of students but different didactical contexts may need more tailored solutions. The work shown in this paper exploits the problem solving potentialities of the TRIZ toolset to provide hints for improving a course focused on teaching a systematic conceptual design method. A set of suggestions has been obtained together some guidelines for applying the considered TRIZ tools to other didactical contexts.
The Finnish Product Development Teachers’ Perceptions of their Pedagogical Content Knowledge in Higher Education
Authors: Mäkelä Elina , Auvinen Petra , Juuti Tero 
Published: July 2019

AbstractThe paper concerns the Finnish product development teacherś perceptions on their pedagogical content knowledge in higher education settings. The aim is to describe and analyse what kind of pedagogical content knowledge the teachers have and, therefore, to provide a better understanding of the type of knowledge unique to product development teaching. The model of pedagogical content knowledge used here includes the components of product development content knowledge, pedagogical knowledge and pedagogical content knowledge. Based on seven teacher interviews, the main content knowledge concerns the process of product development, its different phases and methods as well as the usage of different software programs. The teachers use diverse teaching methods and their attitude towards educational technology is mostly positive. Course learning outcomes and working life are acknowledged when planning teaching, but only a few teachers take curriculum into account and participate in curriculum design. Even though the teachers use different evaluation methods in teaching, new ways of evaluation are needed. This may be something that innovative educational technology tools can make possible.
A Design Case Study: 3D Printer Software Interface Design Based on Home Users Preferences Knowledge
Authors: Li Xuenan , Zhao Danhua , Zhao Jianghong 
Published: July 2019

AbstractThe rapid development of 3D printing technology has an impact on all aspects of modern manufacturing, design and society. However, the home use of 3D printers is still limited by the difficulty in deploying the software and the technology which both need professional understanding and training. How to enable non-technical home users to use 3D printers without the need for training, becomes an urgent problem for both academics and the industry. This paper is concerned in an investigation into home use of 3D printers, their needs and preferences, their impacts on the interaction design of 3D printing. First, a questionnaire survey supported by 127 non-technical users is conducted to understand their preferences on several key steps of the 3D printing procedure. Then, we integrate the survey results into the interaction design process to improve the usability of the 3D printing software. Finally, the advantage of our implementation is tested via the user satisfaction and feedback towards the post-use period. Our design project shows a simple method to extend 3D printing interactive software to non-technical users, and pushes forward the landscape of the home use of 3D printers.
A Methodical Approach to Support Conceptual Design for Multi-Material Additive Manufacturing
Authors: Watschke Hagen , Kuschmitz Sebastian , Heubach Julius , Lehne Guido , Vietor Thomas 
Published: July 2019

AbstractAdditive manufacturing (AM) opens new possibilities for innovative product designs. However, due to a lack of knowledge and restrained creativity because of design fixations, design engineers do not take advantage of AM's design freedom. Especially multi-material AM provides new opportunities for functional integration that hardly considered in ideation. To overcome barriers in the development of solution ideas and utilizing such new design potentials, new design methods and tools are needed. Therefore, in this contribution, a methodological approach for a function-oriented provision of solution principles specific to material extrusion is presented. A tool is developed to facilitate effective guidance in developing solution ideas and to foster a realistic concretization by providing a combination of opportunistic and restrictive AM knowledge. Besides general levers of AM, process-specific design opportunities support the design engineers in exploiting AM's potentials, especially those who are not familiar with Design for AM. Finally, the applicability of the methodological approach is evaluated in an academic study by means of redesigning a hand prosthesis with a grab function.

Published: July 2019

AbstractAdditive Manufacturing (AM) offers the potential to increase the ability to customise large-scale plastic components. However, a substantial amount of manual work is still required during the customisation process, both in design and manufacturing.This paper looks into how the additive manufacturing of mass customised large-scale products can be supported. Data was collected through interaction with industrial partners and potential customers in a case study regarding the customisation of kayaks.As a result, the paper proposes a model-based methodology which combines design automation with a user interface.The results point to the benefit of the proposed methodology in terms of design efficiency, as well as in terms of displaying results to the end user in an understandable format.
Hybrid Prototyping: Pure Theory or a Practical Solution to Accelerating Prototyping Tasks?
Authors: Mathias David , Hicks Ben , Snider Chris 
Published: July 2019

AbstractPhysical prototyping is critical activity in the produce development process, but the cost and time required to produce prototypes hinders it use in the design process. Hybrid prototyping through coupling LEGO and FDM printing is presented as an approach to address these issues. After establishing the separate design rules for FDM printing and LEGO, this paper created new set of rules called Design for Fabrication (DfF) for hybrid prototyping. These cover the three main considerations (Technical, Process, and Design) that the designer and process planning must include to practically implement LEGO and FDM hybrid prototyping. The DfF rules were considered in a prototype of a computer mouse. While the fabrication time was not reduced as expected, it showed that the rules could be practically implemented in a real-world example. Additional considerations were identified that are to be included in the DfF rules.Further work is required to realise the predicted step-change reduction in fabrication time. The first approach is to leverage multiple printers to parallelise the printing. The second is to reduce fidelity while maintaining high fidelity in key regions of interest.
Methodical Approach for Process Selection in Additive Manufacturing
Authors: Wortmann Nadine , Jürgenhake Christoph , Seidenberg Tobias , Dumitrescu Roman , Krause Dieter 
Published: July 2019

AbstractIn recent years, rapid technical progress has led to additive manufacturing achieving a high degree of technological maturity that enables a broad range of applications. This is reinforced in particular by the advantages of the technology, such as the production of complex components, smaller quantities and fast reaction times. However, a lack of knowledge of the various process techniques, such as insufficient potential assessment, specific design guidelines or even of process restrictions, often lead to different errors.This paper presents a methodological approach to support designers in the manufacturing process selection of specific parts at an early stage of product development. In a four-stage procedure, potential part candidates are first identified and part classes formed on the basis of characteristics. Building on this, AM thinking is to be stimulated, for example, with the aid of design guidelines. A comparison between conventionally and additively manufactured parts can be made using a simplified cost model. The results are incorporated into a process model that supports companies in the systematic selection of manufacturing processes.

Authors: Richter Alina , Kessing David , Fischer Fabian , Pelzer Lukas , Dilger Klaus 
Published: July 2019

AbstractThe biggest advantage of Additive Manufacturing is the individualization of products. Mass Customization is well known as a promising future application. The use of Additive Manufacturing for assembly groups is mostly not reasonable, however combining it with conventional manufacturing processes can lead to new opportunities.This paper works out concepts to join, by using similar material combinations, an injection molded part with an additive deposited geometry by the Fused-Deposition-Modeling (FDM) process. Therefore, two of the main industrially used polymers, acrylonitrile butadiene styrene (ABS) and polypropylene (PP), are selected for further study. In particular, this investigation focuses on the procedural potentials and surface preparation of the injection molded part. By the variation of adhesive bonding, the fusion of similar materials can be identified and tested in several series of testing.First in general a direct joining function by the FLM process will be tested. After proving this hypothesis, the results will be summarised in a recommendation of joining similar materials, which are manufactured in different ways.
Alarm Compliance in Healthcare: Design Considerations for Actionable Alarms (In Intensive Care Units)
Authors: Sanz-Segura Rosana , Manchado Pérez Eduardo , Özcan Elif 
Published: July 2019

AbstractIntensive care units are technologically advanced environments that are designed to safeguard the patient while their vitals are stabilized for further treatment. Audible and visual alarms are part of the healthcare ecology. However, these alarms are so many that clinicians suffer from a syndrome called ‘alarm fatigue’ and often do not comply with the task alarm is conveying. Measuring compliance with rules in the workspace and determining the success of a system belongs to the field of ergonomics and is based on data collected through task observations and scoring. In this paper, we will explore compliance with critical alarms by not only from their potential success or failure perspective but also from the perspectives of the clinician capacity, needs, and motivations to comply with alarms in critical environments. We will finally, reflect on further possible design strategies to increase compliance in critical care that are beyond following rules per se but through intrinsic motivation.
An Affordable Insulin Pump for Type-1 Diabetic Patients: A Case Study of User-in-the-Loop Approach to Engineering Design
Authors: Karia Deval , Nambiar Rohit S , Arora Manish 
Published: July 2019

AbstractContinuous subcutaneous insulin infusion using an insulin pump has been documented to have significant clinical benefits as a treatment plan for type 1 diabetes mellitus patients. However, despite this, adoption in resource constrained settings like India is severely limited. This is often attributed to the costs associated with the device.The usage of such a device is closely associated with a patient's lifestyle and its design demands a more user-centric approach to engineering design. The stakeholder involvement is needed for validation and guiding the product development direction. In this paper, we've outlined a user-in-the-loop approach to engineering design using the design of an insulin pump as a case study.
