DIGITAL TWINS - DEFINITIONS, CLASSES AND BUSINESS SCENARIOS FOR DIFFERENT INDUSTRY SECTORS
Authors: Wilking Fabian , Schleich Benjamin , Wartzack Sandro 
Published: August 2021

AbstractOver the recent years, several attempts were made to define the concept of the Digital Twin and to create a generic view for utilizing it within the industry. Still, many industry sectors are not able to transfer a generic definition into their product portfolio, as Digital Twins differ from each other to the same degree as physical products differ from each other. Hence, it is crucial to enlarge the definition towards a classification and business scenarios which enable sector specific views on the concept of the Digital Twin and help SME to utilize the concept towards their products. Future engineers will have to design physical products besides a digital counterpart and therefore have to identify interdependencies between these two products during the development. This paper discusses a generic definition of a Digital Twin that can be applied throughout different sectors as well as a classification for Digital Twins to enable the implementation of the concept on several maturity levels regarding the constraints of the product portfolio. In addition, these classes are viewed in different business scenarios and an outlook is given to further increase the usability of Digital Twins within new industry sectors.
A LOOK INTO CIRCULAR ECONOMY RESEARCH: EXPLORING THE BIO AND TECHNO CYCLES AND THE NEED FOR DUAL CIRCULARITY
Authors: Metic Julija , McAloone Tim C. , Pigosso Daniela C. A. 
Published: August 2021

AbstractThis study undertakes a systematic analysis of literature within Circular Economy (CE) in an industrial perspective, with a focus on understanding the consideration of the biological and technological cycles, as well as dual circularity. The paper articulates the key research differences, gaps and trends on the basis of publication evolution, key subject areas, influential journals and keywords co-occurrence mapping. The analysis shows the increasing publication trend with dominance of technological cycle and a wide variety of subject areas incorporated in CE biological, technological and dual cycles. Due to the multidisciplinary and transversal nature of CE, as well as its diverse interpretation and applications, an expansion and consolidation of the subject areas and journals are expected in the years to come. Analysis of co-occurrence on the authors' keywords underlined a limited focus of a business perspective research within the biological cycle, heterogeneous and proactive technological cycle but fragmented research on dual circularity. Further analysis of synergies and limitations is necessary to enhance business effectiveness towards enhanced sustainability.
ECO-DESIGN ACTIONS TO IMPROVE LIFE CYCLE ENVIRONMENTAL PERFORMANCE OF FACE MASKS IN THE PANDEMIC ERA
Authors: Boix Rodríguez Núria , Marconi Marco , Favi Claudio , Formentini Giovanni 
Published: August 2021

AbstractFace masks are currently considered essential devices that people must wear today and in the near future, until the COVID-19 pandemic will be completely defeated through specific medicines and vaccines. Such devices are generally made of thermoplastic polymers, as polypropylene and polyethylene and are single use products. Even if in this period the sanitary emergency must have the maximum priority, the world society should not completely forget the environmental problem that are causing more and more obvious climate changes with correlated damages to ecosystems and human health. Despite the well-known correlation among anti-COVID protective equipment (or more generally medical devices) and environmental issues, the Life Cycle Assessment (LCA) and eco-design-based studies in this field is very scarce. The present study aims to derive the most important environmental criticalities of such products, by using LCA and product circularity indicators of five different common masks. The final aim is to provide eco-design guidelines, useful to design new face masks by preventing negative impact on the environment.
ESTIMATING DESIGN EFFORT NEEDS OF PRODUCT DESIGN PROJECTS USING CAPTURED EXPERT KNOWLEDGE – A PROPOSED METHOD
Authors: Holliman Alexander 'Freddie' , Thomson Avril , Hird Abigail 
Published: August 2021

AbstractThe quick and accurate estimation of design effort can be make or break for all but the largest of product design consultancies. Traditional design project planning see designers being taken away from the metaphorical drawing board to spend time assessing project briefs and estimating workloads. Typically these designers base these estimates on their tacit knowledge and experience, and for the most part, they are accurate. However, this is time-consuming and therefore (indirectly) costly, as time spent planning, is not time spent designing. Many more sophisticated approaches for estimating design effort have been developed, but many require large bodies of past data and sophisticated analysis, such as artificial neural networks; and others have highly-specific use cases.This paper proposes a new method to develop a design effort estimation tool for product design consultancies. This method captures the tacit knowledge and experience of design team members and the tool replicates it quickly and effectively; graphically modelling factors that influence design effort needs in product design projects.
A MODEL OF CREATIVE HERITAGE FOR INDUSTRY: DESIGNING NEW RULES WHILE PRESERVING THE PRESENT SYSTEM OF RULES
Authors: Harlé Honorine , Le Masson Pascal , Weil Benoit 
Published: August 2021

AbstractIn industry, there is at once a strong need for innovation and a need to preserve the existing system of production. Thus, although the literature insists on the necessity of the current change toward Industry 4.0, how to implement it remains problematic because the preservation of the factory is at stake. Moreover, the question of the evolution of the system depends on its innovative capability, but it is difficult to understand how a new rule can be designed and implemented in a factory. This tension between preservation and innovation is often explained in the literature as a process of creative destruction. Looking at the problem from another perspective, this article models the factory as a site of creative heritage, enabling creation within tradition, i.e., creating new rules while preserving the system of rules. Two case studies are presented to illustrate the model. The paper shows that design in the factory relies on the ability to validate solutions. To do so, the design process can explore and give new meaning to the existing rules. The role of innovation management is to choose the degree of revision of the rules and to make it possible.

Published: August 2021

AbstractVirtual Reality (VR) is progressively adopted at different stages of design and product development. Consequently, evolving interaction requirements in engineering design and development for VR are essential for technology adoption. One of these requirements is real-time positional tracking. This paper aims to present an experimental design of a new real-time positional tracking device (tracker), that is more compact than the existing solution, while addressing factors such as wearability and connectivity. We compare the simulation of the proposed device and the existing solution, discuss the results, and the limitations. The new experimental shape of the device is tailored towards research, allowing the engineering designer to take advantage of a new tracker alternative in new ways, and opens the door to new VR applications in research and product development.

Published: August 2021

AbstractPhysical prototyping during early stage design typically represents an iterative process. Commonly, a single prototype will be used throughout the process, with its form being modified as the design evolves. If the form of the prototype is not captured as each iteration occurs understanding how specific design changes impact upon the satisfaction of requirements is challenging, particularly retrospectively.In this paper two different systems for digitising physical artefacts, structured light scanning (SLS) and photogrammetry (PG), are investigated as means for capturing iterations of physical prototypes. First, a series of test artefacts are presented and procedures for operating each system are developed. Next, artefacts are digitised using both SLS and PG and resulting models are compared against a master model of each artefact. Results indicate that both systems are able to reconstruct the majority of each artefact's geometry within 0.1mm of the master, however, overall SLS demonstrated superior performance, both in terms of completion time and model quality. Additionally, the quality of PG models was far more influenced by the effort and expertise of the user compared to SLS.

Published: August 2021

AbstractThe strive for design principles, qualitative and quantitative design tools, and product development methodologies that enable and support the design of robust products, that is products which are insensitive to noise and variation, is an ongoing challenge for both practitioners and academics. This paper reviews and classifies recent research efforts dedicated to robust design originating from the design society and carves out important challenges and potentials for future research. The main novelty of the paper can be found in the structured analysis and classification of recent robust design efforts as well as in the systematic elaboration of future research challenges, which seeks to stimulate a discussion on future tasks and challenges in robust design research.
A STUDY OF GRAPHICAL REPRESENTATIONS OF UNCERTAINTY IN LCA GUIDE
Authors: Tensa Melissa , Wang Jenna , Harris Roscoe , Faludi Jeremy , DuPont Bryony 
Published: August 2021

AbstractThis study user-tested different data visualizations for highly uncertain life cycle assessments (LCAs) to determine what best supported decision-making. Precise LCAs can only be performed once designs are finalized, due to the information necessary to complete them, but design changes in such late stages are costly. If designers could have environmental impact data earlier in the process, sustainable design choices could instead be built into the initial designs. We compiled LCAs for various product categories, finding the best means of visualizing the data for online and printable dissemination. Because this LCA data varied widely within each product category, it was necessary to display uncertainty and require users to acknowledge the uncertainty. Here, four different data visualizations were tested with engineering, design, and STEM students and professionals; both quantitative and qualitative analysis determined what visualizations were most favored and forced users to consider uncertainty. We hope that this research helps LCA data be more accessible to designers and engineers in the early phases of design, allowing those without the resources or ability to perform LCA to benefit from it and design more sustainably.
A STUDY ON STUDENT: ASSESSING FOUR CREATIVITY ASSESSMENT METHODS IN PRODUCT DESIGN
Authors: Yin Yuan , Han Ji , Huang Shu , Zuo Haoyu , Childs Peter 
Published: August 2021

AbstractThis paper asked participants to assess four selected expert-rated Taiwan International Student Design Competition (TISDC) products using four methods: Consensual Assessment Technique (CAT), Creative Product Semantic Scale (CPSS), Product Creativity Measurement Instrument (PCMI), and revised Creative Solution Diagnosis Scale (rCSDS). The results revealed that, between experts and non-experts, the ranking results by the CAT and CPSS were the same, while the ranking results of the rCSDS were different. The CAT, CPSS, and TISDC methods provided the same results indicating that raters may return the same results on creativity assessment, and the results are not affected by the selected methods.If it is necessary to use non-experts to assess creativity and the creativity results are expected to be the same with that of experts, asking non-expert raters to use CPSS to assess creativity and then ranking the creativity score is more reliable. The study offers a contribution to the creativity domain on deciding which methods may be more reliable from a comparison perspective.

Authors: Schmitt Pascal , Zorn Stefan , Gericke Kilian 
Published: August 2021

AbstractAdditive manufacturing offers several potentials such as the freedom of design, part consolidation, function integration, or time and cost-savings. These potentials make AM interesting for industries such as aerospace, automotive and medical implants, and are also seen as enables for the creation of entirely new business models. Additive manufacturing has the potential to change the current manufacturing landscape substantially and has attracted much attention of industry and academia over the last decades.However, these developments require improvements concerning the technology itself and its successful implementation into the value creation chain. Driven by the promising market opportunities and upcoming technological developments, many research activities started.This paper presents a literature review of publications from the last 20 years. Based on this analysis, the evolution of the AM research landscape is portrayed. The research landscape is organised into four areas: machine and process, material, digital process chain and methodology. The paper summarises developments in each of these areas and concludes by presenting current and discussing future research topics.
A CONCEPTUAL MODEL FOR INTEGRATING DESIGN THINKING AND LEAN STARTUP METHODS INTO THE INNOVATION PROCESS
Authors: Marion Tucker , Cannon David , Reid Tahira , McGowan Anna-Maria 
Published: August 2021

AbstractDesign thinking is a methodology that comes from the industrial design realm and is centred on culling better needs insight from users. Another popular methodology is based gaining insight on the potential of an opportunity through experimentation, testing, and iterating with users. This is commonly referred to as lean startup methods. However, from a research perspective, we still do not know the most effective way to implement these user focused design methods within the innovation process within organizations, and which aspects of the design process are the most impactful in developing new opportunities. In this research, we propose a high-level conceptual process model on how user focused design methods such as design thinking and lean startup methods can be integrated into the up-front innovation process within organizations. We review the conceptual model, associated activities, and process considerations. The article concludes with thoughts on future research.
EXPLORING SUSTAINABLE PRODUCT DEVELOPMENT PROCESSES FOR A CIRCULAR ECONOMY THROUGH MORPHOLOGICAL ANALYSIS
Authors: Diaz Tena Anna , Schoeggl Josef-Peter , Reyes Tatiana , Baumgartner Rupert J. 
Published: August 2021

AbstractOver the last years, academic literature has made significant progress on the development of key concepts, identifying circular product typologies, developing assessment methods, and exploring the synergies with manufacturing trends such as digitalisation or environmental management. Nevertheless, less attention has been paid on describing process model changes necessary for the implementation of circular product development. For this reason, this paper presents the circular Sustainable Product Development (cSPD) morphological field, aimed at providing implementation guidance to business and industry. It describes possible reconfigurations of the Sustainable Product Development (SPD) process model to further integrate circularity R-strategies, design scopes, design guidelines, inter- and intra-organisational actors and criteria for evaluation. With this framework, we intend to identify the most defining parameters in the process model and assign them a discrete number of categorical values so that different combinations explain the generation of prevalent circular product typologies in the manufacturing of durable goods.

EXTENDING PRODUCT FAMILY DESIGN METHODS TO PRODUCT-SERVICE-SYSTEM FAMILY DESIGN
Authors: Rosen David , Choi Young Mi 
Published: August 2021

AbstractAlthough product family design methods are well established, little research has focused on Product-Service-System (PSS) family design. A PSS family design method is proposed in this paper that parallels methodology for designing product families. Separate platforms are proposed for products and for services. However, couplings between product and service platforms are identified and incorporated into the design method. Design problem formulations are proposed for PSS family platforms and for the PSS family itself, using a module-based approach, in contrast to a platform scaling approach. Alternative methods are investigated and compared for solving these problems. The application domain of Assistive Mobility (AM) is identified as a promising PSS family in this work. If smart technologies are integrated into AM devices, such as manual wheelchairs, powered wheelchairs, walkers, and rollators, then patient diagnosis and treatment, as well as device maintenance, services are enabled with these smart technologies, demonstrating that smart AM devices are a promising PSS family.
FORMULATING GUIDELINES FOR THE SYSTEMATIC SET-UP OF EXPERIENTIAL MATERIAL CHARACTERIZATION STUDIES: A CASE OF PLASTIC DEMONSTRATORS
Authors: Veelaert Lore , Moons Ingrid , Du Bois Els 
Published: August 2021

AbstractMaterials can be considered from a technical and experiential perspective. However, the latter perspective is more complex to study systematically. Four intertwined experiential levels describe the overall materials experience: sensorial, interpretive, affective, and performative level. Building upon the need in experiential material characterization for comparable physical material representations to enable within-material-class comparisons and the inclusion of extensive user aspects, this paper sums up the reasoning process regarding the understanding and design of an experimental set-up and its parameters of a specific case. The case objective is to formulate guidelines for the designer/researcher to set up experiential material characterization experiments with (i) plastic demonstrator forms and (ii) by consumers. Following elements are discussed: Assessors, Stimuli, Interaction Modalities, Dependent variables, Method, and Practical considerations. Next, future experiments can be carried out in order to generate holistic plastic material data on a larger scale, that can be collected in an experiential database and used by designers throughout the design process.
FROM REQUIREMENTS TO PROTOTYPING: APPLICATION OF HUMAN-SYSTEM INTEGRATION METHODOLOGY TO DIGITAL TWIN DESIGN
Authors: Camara Dit Pinto Stélian , Masson Dimitri , Villeneuve Eric , Boy Guy , Urfels Laetitia 
Published: August 2021

AbstractIndustrial digital transformation is bringing a need for new tools and concepts. However, designing such complex tools and concept requires methods to be correctly implemented. These methods are studied as part of system engineering to satisfy various identified goals, and more specifically human-system integration, which is the topic of this paper. This article introduces the method used to define key elements of human perception of reality called reality anchors to design scenarios to be tested in a digital twin prototype. This method goes from regulation study to user cognitive function analysis on the specific case of digital twin designing in oil-and-gas industry. This method highlighted the differences between theoretical process and the followed process as well as tools and competencies used to identify reality anchors. This knowledge will then be used to implement a new process to be implemented with a digital twin and scenarios to test the prototype using realistic simulation.
FROM THE DEFINITION OF USER EXPERIENCE TO A FRAMEWORK TO CLASSIFY ITS APPLICATIONS IN DESIGN
Authors: Berni Aurora , Borgianni Yuri 
Published: August 2021

AbstractThe concept of User Experience (UX) dates back to the 1990s, but a shared definition of UX is not available. As design integrates UX, different interpretations thereof can complicate the possibility to build upon previous literature and develop the field autonomously. Indeed, by analysing the literature, UX emerges as a cauldron of related and closely linked concepts. However, it is possible to find recurring attributes that emerge from those definitions, which are ascribable to two foci: the fundamental elements of the interaction (user, system, context) and typologies of experience (ergonomic, cognitive, and emotional). Those are used to build a framework. We have preliminarily investigated how UX is dealt with in design by mapping a sample of UX-related experimental articles published in design journals. We classified UX case studies based on the framework to individuate the UXs that emerge most frequently and the most studied ones in the design field. The two-focus framework allows the mapping of experiments involving UX in design, without highlighting specific favorable combinations. However, comprehensive studies dealing with all elements and UX typologies have not been found.
HOW FAMILIARITY IMPACTS INFLUENCE IN COLLABORATIVE TEAMS?

Published: August 2021

AbstractIndividual traits strongly impact team composition and the biases arising from them can also impact design activities. One such bias highlighted in the study is the familiarity bias (i.e., a bias that might be present between the two individuals due to their prior acquaintance). In order to detect the familiarity bias, participants from 4 universities who evaluated their peers and rated them for (1) their perceived degree of influence, (2) trust, (3) the amount of agreement they had with the other team member and (4) the amount of agreement the other individual in the team had with them. It was found that familiarity bias exists in collaborative teams. Its impact on the four variables, especially on influence, was discovered. In the end, the study briefly highlighted the importance of studying the factors (like the one revealed in this study) that affect influence in design teams as it eventually impacts design outcome. It was found that the individuals who explore most idea clusters, are less likely to be perceived influential and teams having the most influence produced a smaller number of idea clusters. Overall, the study contributes to understanding the factors affecting human cognition and behaviour in the design teams.
