Authors: Bos Mikaël Ivar , Karahanoğlu Armağan , Haarman Juliet , Nizamis Kostas 
Published: June 2023

AbstractHome hand rehabilitation for stroke is becoming increasingly important due to logistic and financial challenges. Developing Daily-life Integrated Hand-rehabilitation Products (DIHP) aims to enable the application of at-home rehabilitation. The materials of these products are essential for their success, however, selecting materials for DIHP has not been investigated yet. Previous research on material selection showed that it is done strictly on material properties or based on a human-centered approach. Hence, in this study, we propose a hybrid model for choosing materials for DIHP. To achieve this, we first combined the findings of previous material selection processes into a comprehensive material selection model. We applied this model in a case study, in which we first selected three materials based on their properties. Following, we 3d printed a DIHP out of the chosen materials and tested the feeling of the materials with multiple expert groups. Our findings suggest that the proposed material selection method is promising and highlights that our comprehensive model provides more insights when compared to a strict material property-based selection.
UNCERTAINTY MANAGEMENT IN CIRCULAR BUSINESS MODEL INNOVATION – THE CASE OF CIRCULAR PLASTICS
Authors: Stingl Verena , Fuglsig Linea Vibe , Hoveling Cecilie 
Published: June 2023

AbstractThe transition towards circular economy means a radical systemic shift that requires re-design and innovation of business models. However, this radical systemic shift also creates high levels of uncertainty, which pose challenges to the circular business model innovation (CBMI) process. Using the transition towards circular plastics as a case context, this study aims to conceptualize different forms of uncertainty affecting CBMI, and to link them with approaches for managing these uncertainties. Based on interviews with incumbent manufacturing firms that have transitioned to circular plastics, or are in the process of doing so, we identified three domains of uncertainty: goal uncertainty, development uncertainty, and outcome uncertainty. We discuss the nature and sources of these uncertainties, and present different approaches chosen by manufacturers to manage these uncertainties in the context of their business. Our findings highlight the complex nature of uncertainty, and the importance of a nuanced consideration of uncertainty as a factor in the CBMI process. Moreover, our mapping of core uncertainties for CBMI and approaches to manage these uncertainties can guide practitioners in the innovation process.

Published: June 2023

AbstractThe product development process faces several challenges, such as an increasing and differentiated number of customer requirements, increasing product complexity, and shortened time-to-market. To address these challenges, the implementation of automation approaches in form of machine learning (ML) algorithms appears promising. However, companies lack the implementation of these approaches in their processes, inter alia due to inadequate knowledge and experience in this field. Therefore, the aim of this paper is to develop a structured formulized way of characterising ML algorithms, which can support non-experts in identifying the optimal algorithm to solve a given problem. First, existing approaches covering the determination of appropriate ML algorithms for a given task are examined. Based on this, a pattern language approach is introduced to characterise ML algorithms and problems, allowing matching to be performed to identify the most suitable one for a given task. Due to their broad application, the concept is demonstrated by creating patterns for decision trees and artificial neural networks. A study is conducted to prove that the proposed concept is appropriate to support the ML algorithm selection.
UNDERSTANDING UPCYCLING AND CIRCULAR ECONOMY AND THEIR INTERRELATIONSHIPS THROUGH LITERATURE REVIEW FOR DESIGN EDUCATION
Authors: Sung Kyungeun 
Published: June 2023

AbstractDesign and engineering are fundamental activities in shaping the world we live in. Educating new generations in design and engineering, therefore, is crucial to build a better and more sustainable world. The changes in education for the transition from a linear economy to a circular economy, in particular, has become a priority for many educators. Aligned with the circular economy, a promising umbrella concept and practice called 'upcycling' is emerging. The concepts and practices in the circular economy and upcycling overlap depending on the definitions of the terms in various disciplines and sectors in different parts of the world. This has caused some confusion and misunderstanding. For educators aiming to teach students about sustainable design, production and consumption, it is beneficial to distinguish between these two concepts. Understanding the relationships (or interrelationships) between them in theory and practice is important for the educators to offer clear guidance and recommendations to future designers and engineers. This paper provides literature review on upcycling and circular economy, compares these two concepts, and visualises their interrelationship as draft teaching materials for design education.
USE CASES FOR A HYBRID AUGMENTED REALITY COMPUTER WORKSTATION IN CAD WORKFLOWS
Authors: Harlan Jakob , Goetz Stefan , Wartzack Sandro 
Published: June 2023

AbstractMany immersive approaches for design activities show a great potential for their specific use cases, but still overall usage of extended reality technology in product developers day-to-day work is little. The user's workflow between classical desktop work environment and its immersive counterpart is interrupted by both a data gap and an interface gap. The three-dimensional product data usually needs preparation and the user has to physically change the interface in use. The hybrid augmented reality computer workstation aims to close these gaps. A hologram of the current model is visualized next to the screen in reach of the user for intuitive inspection and spatial interactions. In this paper we present use cases for this novel immersive workstation in the CAD workflow. An explorative user study of the typical product designer`s workflow reveals the most common activities. Guided by those, eight uses cases are formulated and classified into fundamental, drafting, and modelling CAD tasks. These cases include novel hybrid augmented reality interactions derived from literature, which are assessed with respect to their applicability.
USING LIKELIHOOD RATIO TABLE AND NAÏVE BAYES CLASSIFIER METHOD TO HOLISTICALLY ASSESS CODESIGN PROGRAMMES AND METHODS
Authors: Siew William , Silva Arlindo , Rai Bina 
Published: June 2023

AbstractThe concept of inclusivity involved an understanding of people, programmes and places, embedded with complex issues. 21 student designers took part in a first-of-its-kind five-day codesign programme to develop solutions for inclusive and engaged communities with residents. This quasi-experimental study aimed to develop a value-based approach using likelihood ratio table and a Naïve Bayes classifier method to assess the success of a codesign programme, in comparison to past programmes with different design challenges. Methodology proposed a systematic investigation to evaluate this programme holistically. Students discussed with stakeholders to uncover the complexities of human and environmental factors in design at early stage of ideation, and semi-structured participants’ observation tasks were considered instead of researcher's observations in the method of assessment. Selected teams were introduced to two new design methods to empathise better with seniors, i.e., Care Circle and See and Shoot. Findings revealed that these teams showed greater levels of critical inquiry when overcoming three key challenges, i.e., (1) identifying key personas, (2) examining potential use environment, and (3) access to market.
VEGETABLES AND FRUITS IN A CIRCULAR ECONOMY: PACKAGING CHALLENGES AND DESIGN OPPORTUNITIES
Authors: Broucke Juliette , Noeth Esther , Du Bois Els 
Published: June 2023

AbstractPackaging of potatoes, vegetables and fruits (PVF) currently deals with the fragile opposition of food waste reduction and packaging resource consumption. In order to understand how designers can rethink this always negative balance and outcome of waste creation, research was done to understand packaging and preservation of PVFs from both a technological and consumer perspective. A mixed research approach was applied, including literature study, expert interviews, packaging analyses, consumer survey and photo study. In sum, we concluded that the main function of packaging is preservation, including both protection from outside influences and conservation in best possible conditions. Optimal preservation should consider each PVF's respiration and transpiration needs, and ethylene sensitivity. Consumers are mostly not aware of correct preservation methods. However, on the other hand, their awareness evokes an important tendency to ban plastics without considering their positive impact on food preservation. In the paper, design opportunities are formulated for new reusable packaging, reducing waste creation and offering higher quality in food preservation and consumer experience.
VIBRATION REDUCTION OF A HAMMER DRILL WITH A TOP-DOWN DESIGN METHOD
Authors: Le Philip , Xu Duo , Vazhapilli Sureshbabu Anand , Zimmermann Markus 
Published: June 2023

AbstractDesigning vibrating systems is challenging due to component interaction. One approach to reduce the resulting complexity is top-down design where requirements on components are formulated such that the overall system achieves the design goal. Previous work showed how to derive quantitative and solution-neutral requirements on components of a vibrating system, expressed as permissible ranges of impedance. This work adapts the methodology to a practical use case and provides a concrete technical solution: A hammer drill that can cause white finger syndromes to users is equipped with an appropriate vibration absorber. The hammer drill is represented by a lumped mass model and validated using experimental data of a reference design. Solution-neutral and quantitative component requirements on the overall dynamics of the vibration absorber expressed by impedance are derived. They provide a clear target for the component design. A vibration absorber in form of a Tuned Mass Damper (TMD) is designed accordingly. The final design is validated experimentally and shown to reduce the vibration by 47%.
WHAT DETERMINES VR INTEGRATION IN DESIGN PRACTICE? AN INVESTIGATION OF INDUSTRIAL DESIGNER'S ACCEPTANCE OF VR VISUALISATION TOOLS

Published: June 2023

AbstractEmerging visualisation tools based on eXtended Reality (XR) platforms offer designers new possibilities and benefits, attracting increasing interest from academia and industry. However, as the users and consumers of these tools, practising designers' perceptions of XR visualisation tools need to be further verified as they shape the tools' acceptance and integration in the industry. This paper investigates industrial designers' acceptance of VR visualisation tools using the Unified Theory of Acceptance and Use of Technology (UTAUT) model. Semi-structured interviews were undertaken with 12 designers from 3 countries to discuss their attitudes, motivations, experiences, and expectations regarding adopting VR visualisation tools as professional tools. The study highlights key opportunities to promote VR integration in industrial design as the tools' practical capabilities to support design performance and the social influence of stakeholders and peer designers on the professional use of VR. The main barriers lie in designers' expected effort to learn and use the tools and the investment and upkeep of VR systems and facilities in the industry. The paper concludes with recommendations for reaping benefits and overcoming barriers.
WILL MODEL-BASED DEFINITION ACCELERATE THE INSPECTION PHASE IN THE MANUFACTURING PROCESS?
Authors: Uski Pekka , Nieminen Joni , Ellman Asko 
Published: June 2023

AbstractModel-Based Definition provides several benefits for communicating between engineering and other downstream stakeholders. Particularly, semantic PMI information included in 3D models benefits both CAM programming and inspection phases. However, the efficiency of generating CAM- and CAI codes automatically according to the semantic PMI information varies due to the compatibility of different systems. This paper focuses on the experiment that we made on inspecting three different parts with the Coordinate Measuring Machine (CMM). We compared four different programming methods and found that the efficiency of inspecting depends on the serial size of the parts. The completely automatic CAI-programming method does not necessarily produce the most effective CAI code compared to the competent human programmer. This is notable, especially in large series due to achieved cumulative time savings in the inspection of each part. With small series, fully automatic PMI method and human-assisted automatic PMIfp method provide significant benefits in the inspection process due to time savings in CAI-programming work.
A BOUNDARY OBJECT FOR MAPPING, COMPARING, AND INTEGRATING PRODUCT DESIGN METHODS
Authors: Velleu Jesse , Brei Diann , Gonzalez Richard , Luntz Jonathan 
Published: June 2023

AbstractThere are innumerable design methods that exist across a wide spectrum of disciplines, ranging from engineering, to marketing, to psychology. However, the organic, multidisciplinary nature of methodological development in design leads to challenges in comparing or combining methods. Disciplinary perspectives can create conceptual 'boundaries' that may not align with the fluidity of the problems that designers may need to address. It is challenging to work between the boundaries of these design methods due to the unclear delimitation of exactly where and how methods may be integrated. Nomenclature is unstandardized and different terminologies may describe similar phenomena. To address this, a boundary object—the Actor-Abstraction matrix—is developed to recontextualize each of these divergent methods onto a common scale so they may be better understood in reference to their peers. A meta-analysis of four established design methods is performed to demonstrate the flexibility of this conceptual device. With this tool, existing design methods may be more easily examined to identify points of compatibility and gaps in their coverage, and could also serve as a powerful platform for the creation of new design methods in the future.
A VALUE-DRIVEN DESIGN APPROACH FOR THE VIRTUAL VERIFICATION AND VALIDATION OF AUTONOMOUS VEHICLE SOLUTIONS
Authors: Bertoni Marco , Thorn Stefan 
Published: June 2023

AbstractAutonomous vehicle solutions (AVS) are regarded as a major enabling technology to support the realization of 'total site solutions' in the construction equipment industry. Their full-scale deployment is hindered today by the need to test autonomous driving capabilities against the varying conditions an AVS is expected to be exposed to during its lifetime. Therefore, using virtual simulation environments is common to overcome the cost and time limitations of physical testing. A caveat in this virtual verification and validation (V&V) work is how to trade off the ‘realism’ of the V&V output (using high-fidelity models across many scenarios) against computational time. This research investigates expectations and needs for value-driven decision support in the virtual V&V process, proposing an approach and a tool to raise awareness among decision-makers about the value associated with using selected simulation models/components in the virtual verification and validation task for AVS. Verification activities performed on the initial prototype show that its main benefit lies in facilitating cross-domain negotiations and knowledge sharing when negotiating the desired features of the virtual simulation environment.
ACCESSIBLE SOLAR ENERGY TECHNOLOGY FOR DOMESTIC APPLICATIONS IN THE UK: EDGE SOLAR
Authors: Heaton Alex , Sung Kyungeun , Isherwood Patrick 
Published: June 2023

AbstractRenewable energy is increasingly used and promoted. In the UK, for example, large scale renewable energy farms have been used to supply electricity with great effect. Given the large number of homes, there is considerable impact to be made by small scale residential renewable energy systems. Despite solar panels being the most common form of residential renewable energy technology, only 4% of buildings in the UK support solar technology of any kind. For direct electricity generation, silicon-based photovoltaic (PV) arrays are the most utilised, and when used in a residential setting, they are typically mounted on the sloped roofs. This is where the problem lies. The technology comes with a high cost, and there is further financial burden of installation and maintenance, making solar energy inaccessible for many UK homeowners. This paper presents a research and design innovation project to make PV technology more accessible in the UK. Edge Solar, the innovative, affordable, new PV system concept for UK homes may become a promising solution to significantly improve the accessibility to the PV technology and renewable energy at the household level in the UK and beyond with further development and commercialisation.

Published: June 2023

AbstractSustainability in engineering sciences is of rapidly growing importance. However, its integration into engineering education is still in its infancy. This paper is based on the finding that, in addition to conventional cognitive learning outcomes, affective outcomes like mindset and attitude play a major role in teaching sustainability effectively. We present the didactical theory behind this and the evaluation of two university courses which serve as practical examples and research objects. These course puts high importance on affective learning outcomes, teaching not only design and assessment methods but also encourages students to reflect sustainability goals in broader contexts. We describe the theoretical course design following the principle of constructive alignment and conducted a quantitative and qualitative evaluation of the learning outcomes. The evaluation results confirm the importance of affective learning goals but also point out the need for further improvements to the course, which were implemented and re-evaluated.
A CASE STUDY OF MULTIFUNCTIONAL NON-PNEUMATIC TIRE DESIGN FOR THE VALIDATION OF META-LEVEL DESIGN PARAMETER IN DOMAIN INTEGRATED DESIGN (DID) METHOD
Authors: Velivela Pavan Tejaswi , Letov Nikita , Kong Lingchen , Zhao Yaoyao Fiona 
Published: June 2023

AbstractThe work introduced two novel multiscale multifunctional tire designs developed using the Domain Integrated Design (DID) method and modelled with the LatticeQuery geometric modelling software. Furthermore, this research validates the meta-level parameter “interaction area” proposed for selecting biological analogy in the DID method. These two use cases were simulated with Abaqus. The concepts covered in this work are an example of multi-functional design. The obtained results validate the meta-level parameter derived from the DID methodology.
AN APPROACH FOR THE INCLUSION OF LOADING CONDITIONS IN A POLYHEDRAL-BASED METHOD FOR EARLY VARIATION MANAGEMENT
Authors: Restrepo Garcia Carlos Andres , Teissandier Denis , Anwer Nabil , Ledoux Yann , Delos Vincent , Pierre Laurent , Garcia Gomez Sonia Carolina 
Published: June 2023

AbstractThe variation management and product quality processes are important tasks to guarantee the assemblability of the systems, the scrap reduction and to avoid delays on production and launching. The compound of activities in Geometric Dimensioning and Tolerancing (GD&T) are necessary, especially in the early design stages, to take into account variations of different nature and from different sources. In this paper, an approach for considering the loading conditions in a polyhedral-based approach in tolerancing design is presented. The load boundary conditions are represented as additional displacement restrictions in the deviation space. The restrictions imposed by the physical limits of a system, the ones coming from the loading conditions and the degrees of freedom (DoF) can be all described and represented with a single polyhedron operand. The approach is illustrated using a simplified 2-D model for both ideal and non-ideal geometry. A 3-D model describing an unilateral contact is presented as a case study using Skin Model Shapes. By taking into account geometrical form defects, external loads, and the kinematics of the system, its sensitivity to variations can be reduced even from early design stages.
AN SE BASED MARITIME VESSEL DEVELOPMENT FRAMEWORK FOR CHANGEABLE PROPULSION SYSTEMS
Authors: Sullivan Brendan , Rossi Monica 
Published: June 2023

AbstractReducing Greenhouse Gas Emissions from vessels is one of the greatest challenges the maritime industry is currently facing. International Maritime Organization has set the goal of reducing CO2 emissions from international shipping by at least 40% by 2030, compared to 2008. Emissions regulations are also leading to a progressive reduction of ships life span, together with a decrease in economic value. To cope with these challenges, the preferred strategy suggested by IMO for new vessels -Energy Efficiency Design Index- aims at increasing the energy efficiency over time by stimulating innovation and continuous development of technical elements. In this context, ship builders are indirectly led to develop vessels that will be “changeable” in terms of propulsion systems over time. This paper presents a conceptual framework to maritime vessels for propulsion system changeability, which integrates contributions from literature review with the knowledge of design thinking experts and precious insights of maritime industry professionals. The aim of this framework is support the integration of renewable fuel sources for vessel propulsion systems through an extended value approach, while improving propulsion efficiency over time.
