THE ROLE OF DESIGN IN INTERDISCIPLINARY PRODUCT DEVELOPMENT – CHALLENGES, RESEARCH APPROACHES AND FURTHER RESEARCH NEEDS
Authors: Stöhr Bernd , Koldewey Christian , Dumitrescu Roman 
Published: June 2023

AbstractIn global competition, companies are continuously searching for a competitive advantage. A growing number of companies have identified the design of their products as a major success factor. The promises for companies associated with outstanding design are extremely attractive, ranging from better customer experience to higher sales growth. But even though the advantages of design seem to be compelling, companies are still having difficulties in leveraging the benefits of design.In this paper, we want to identify the underlying challenges that explain this gap. We are especially interested in the role and challenges of design in interdisciplinary product development. Therefore, we perform a literature review that clarifies terminology, analyses research approaches and identifies challenges. We determine seven key challenges for design in interdisciplinary product development. Furthermore, we observe a limited scope of research approaches in the reviewed literature. Based on these findings, we propose three further research directions to strengthen the role of design in interdisciplinary product development in the future.
THE ROLE OF STORYTELLING AS AN ANALYTICAL TOOL IN SCIENTIFIC RESEARCH
Authors: Singh Vishal , Tomar Reet 
Published: June 2023

AbstractThis paper reports the preliminary findings from ongoing research on the potential role of storytelling as an analytical framework in assessing a research project. It is noted that most existing research on storytelling in science is focused on science communication. There is limited research on storytelling as an analytical tool for analyzing and synthesizing research plans and design. This research is based on the premise that the assessment of a research project and design is based on reviewing one or the other form of research communication, whether it is a research plan, a research report, or a presentation. Thus, the assessment is mediated by how well the research plan, proposal, report, or presentation, communicates the research to the reviewer and how well it connects the dots. The reported findings are based on studies with two different storytelling frameworks applied to assess research representations made by doctoral researchers as part of their annual research progress review. The paper reports the details of the research approach, the empirical study, and preliminary findings from the collected data.
A NEW RESEARCH PROTOCOL FOR USING SYSTEM MAPS IN SYSTEMIC DESIGN RESEARCH
Authors: Moons Stine , Noëth Esther , Du Bois Els , Jacoby Alexis 
Published: June 2023

AbstractSystem maps are established tools in design practice and education as well as non-design research, both as a process and an outcome of systemic analysis and synthesis. Applying causal loop diagrams (CLD's) in (systemic) design research could be of great value to tackle the growing societal complexity. At this moment there is, however, no clear research protocol to include the rich data necessary for systemic research and ensure a scientifically valid system map in the context of design research. In this paper, we propose a protocol using CLD's as a research method and outcome in design-inclusive research. The protocol synthesises rich data from qualitative research in a way that the representation yields higher validity compared to the regular approach to systems mapping, using a process of reflection and iteration on boundary setting. An iterative process of qualitative research methods with lean validation methods was used to come to a conceptual proposal. The protocol can support systemic design researchers and practitioners to include a scientifically grounded CLD in the explorative research actions phase, thus bridging the research towards a phase of creative design actions.
THE STUDY OF COGNITIVE DIFFERENCES BETWEEN DESIGNERS AND USERS BASED ON SCHEMA THEORY
Authors: Guo Su , Fan Shengxi , Meng Yichen 
Published: June 2023

AbstractThis study is grounded upon the cognitive process and knowledge representation, analyzes the differences in perceptions between designers and users by applying schema theory. Per design process, we disassembled the semantic words that represent the design concept, and re-construct the representative visual imagery library. We experimented the imagery library with selective designers and users, and through their selections of the images, we uncovered: 1. The differences largely exist in concept interpretation and imagery selection between designers and users, which has strong relationship with their different schema; 2. The experiment revealed the fact that designers are inclined to understand the concept by disassembling the elements, and have obvious tendency of professionalism, while users’ interpretation prefers complete forms and life-oriented; 3. As compared with users, designers relatively prefer brand-new, creative elements in selecting visualized representation.
THE USE OF ORGANIC RESIDUES TO DEVELOP PACKAGING: TESTS IN MOLDED PULP

Published: June 2023

AbstractAt the end of its life the packaging may become a residue if it is not correctly discarded, becoming a visible component of the waste produced on the planet, with a defined shape and communicating with the world. In the same way, large-scale agricultural production generates organic residues that, although representing fiber-rich materials, are discarded, such as rice husk, coconut husk, wood fibers, among others. To contribute with solutions to minimize the environmental impact of packaging and organic residues, the present study aims at performing preliminary tests of molded pulp packaging manufacturing from organic residues, in a circular economy context. Action research was used as the method to guide the collective construction (project team and partner companies), and the direction of the preliminary tests of packaging to be manufactured. The tests performed on coconut fibers in transfer molding and thermoforming were promising, but they required the addition of binder substances like byproducts from starch, especially in the transfer molding method. Besides using fibers from alternative sources to cellulose, the proposed packaging is potentially compostable and may replace non-renewable material like oil-based polymers.
TOWARD A HUMAN SYSTEMS INTEGRATION APPROACH TO THE DESIGN AND OPERATION OF A REMOTE AND VIRTUAL AIR TRAFFIC CONTROL CENTER
Authors: Disdier Alexandre , Masson Dimitri , Brethomé Thomas , Jankovic Marija , Boy Guy-André 
Published: June 2023

AbstractRemote and virtual centers have been studied for the past twenty years as an alternative to the traditional air traffic control tower environment. Designing such complex sociotechnical systems requires a systems engineering approach that appropriately integrates the human element as well as the technological and organizational components. In this paper, we identify the challenges of implementing this human-systems integration in the design of complex systems. We present the feedback we obtained from a series of semi-structured interviews with people involved in the development of military air traffic solutions. The participants' responses helped us establish methodological guidelines for designing and building a disruptive remote and virtual air traffic control center. We discuss how virtualized human- in-the-loop simulations in particular should help designers analyze user activity and be more flexible in system acquisition.
TOWARDS REALISTIC NUMERICAL MODELLING OF THIN STRUT-BASED 3D-PRINTED STRUCTURES
Authors: Dash Satabdee , Nordin Axel 
Published: June 2023

AbstractThe as-built geometry and material properties of parts manufactured using Additive Manufacturing (AM) can differ significantly from the as-designed model and base material properties. These differences can be more pronounced in thin strut-like features (e.g., in a lattice structure), making it essential to incorporate them when designing for AM and predicting their structural behaviour. Therefore, the aim of this study is to develop a numerical model with realistic characteristics based on a thin strut-based test artefact and to use it accurately for estimating its compressive strength. Experiments on test samples produced by selective laser sintering in PA 1101, are used to calculate geometrical deviations, Young's modulus, and yield strength, which are used to calibrate the numerical model. The experimental and numerical results show that the numerical model incorporating geometrical and material deviations can accurately predict the peak load and the force-displacement behaviour. The main contributions of this paper include the design of the test artefact, the average geometrical deviation of the struts, the measured material data, and the developed numerical model.
TRANSPORT EFFICIENCY OF DELIVERY TRUCKS: A STUDY OF COUPLING VEHICLE DESIGN AND TRANSPORT SYSTEM THROUGH FUNCTIONAL MODELLING AND OPTIMISATION
Authors: Shahrezaei Khashayar , O'Reilly Ciarán J. , Lähivaara Timo , Göransson Peter 
Published: June 2023

AbstractTo enable the emergence of new and efficient vehicle design from the transport system perspective, a formulation of a multifunctional vehicle-transport design optimisation problem is presented. System- wide measures of transportation and vehicle efficiency measures are conceptually considered in an integrative design approach to drive the transport solutions towards more resource-efficient and eventually more sustainable solutions. Considered efficiency measures associated with the system-wide aspect are namely, productivity and service efficiency, and measures associated with vehicle attributes are namely mass and shape efficiency. The conflicting nature of these measures is balanced using optimisation methodologies through multiple transportation scenarios with varying transport demand and deterministic drive cycles. The obtained optimisation results demonstrated that there is a strong interconnectivity between the vehicle's overall configuration and transportation aspects. Thus, conceptually demonstrating how the inclusion of various transport-vehicle efficiency measures simultaneously in an integrative design approach during the early vehicle design may yield a more efficient and better overall system performance.
TRASH TALK: WHO USES WHICH REUSABLE PRODUCT? USER INSIGHTS AND DESIGN OPPORTUNITIES FOR SINGLE-USE ALTERNATIVES
Authors: Herweyers Laure , Du Bois Els , Moons Ingrid 
Published: June 2023

AbstractSingle-use products often end up in the environment as waste, threatening ecosystems and human life. This indicates a need to transition towards sustainable reuse routines. In this study, we investigate to what extent reusable products are already established in society and what design properties users require. We compare the results between user clusters and countries. To create a meaningful list of reusable products to investigate, we distinguish four categories based on typical barriers by means of focus groups (n=3) and interviews (n=32). Next, we did a survey (n=3000) in three countries (Belgium, Russia, U.S.) to define user clusters and investigate product usage and design requirements. Most established products are hard-material products such as lunch boxes, while intimate hygiene products, such as menstrual cups, are not established yet. Multifunctionality and compactness are the most indicated product requirements. There are significant differences between countries and clusters for both research questions. We conclude that different types of users have different needs: while a sharing system might work for one group, a customizable option would be more suitable for others.
UNCERTAINTY MANAGEMENT IN PRODUCT DEVELOPMENT PORTFOLIOS: THE IMPACT OF GLOBAL SUSTAINABILITY AGENDAS
Authors: Filipovic Andy Mattulat , Welo Torgeir , Willumsen Pelle Lundquist , Oehmen Josef 
Published: June 2023

AbstractIncreased focus on sustainability significantly impacts product development portfolio management in organizations. This paper focuses on the significant unaccommodated uncertainty caused by the green transition for current mid- and long-term portfolio management processes. These uncertainties arise in areas such as the regulatory environment, market demands, and technical capabilities. This paper makes four contributions: First, current product portfolio management literature is mostly employing deterministic practices. Uncertainties are incompletely addressed, and current methods fail to address the deep uncertainties of the green transition. Second, building a literature-based conceptual framework of the sources of uncertainty in 6 areas: Business Models, Technology, Regulation and Legislation, Finance and Insurance, Market and Consumer, and Organizational Context. Third, preliminary empirical evidence supports the usefulness of our model for product development portfolio management. Fourth, concluding with a suggested empirical research agenda to develop a deeper understanding of challenges towards method and theory development to support the green transition on the portfolio management level.
USING PLEASURABILITY TO COMPARE WRISTWATCHES AND IOT SMARTWATCHES: PROVIDING NOVEL INSIGHTS INTO UX DESIGN
Authors: Lin Zidong , Ahmed-Kristensen Saeema , Hall Ashley , Sommer Bjorn 
Published: June 2023

AbstractThe emergence of the Internet of Things (IoT) has brought more challenges for designers to fully understand networked objects and develop pleasurable user experiences (UXs). Due to the radical change of products when they are connected, traditional experience design theories may not be applicable in this new context. Based on two well-established UX design theories, this paper presents a survey study that investigated the pleasurability of IoT devices by comparing a representative IoT device (i.e., the smartwatch) and its conventional form (i.e., the wristwatch). An online questionnaire was deployed to gather feedback from parallel wristwatch and smartwatch users. Their experiences using both types of watches were quantitatively and qualitatively compared by data analysis. The results highlighted the differences in UXs between smartwatches and wristwatches in three types of pleasure and five psychological needs. The study revealed design opportunities to improve the pleasurability of smartwatches and provides novel design insights informing the development of pleasurable UXs for future IoT devices.
VIBRATION REDUCTION BY TUNED MASS DAMPERS INSIDE CAVITIES OF TOPOLOGY OPTIMIZED LATTICE STRUCTURES
Authors: Janousek Marc Konrad Bernd , Xu Duo , Vazhapilli Sureshbabu Anand , Zimmermann Markus 
Published: June 2023

AbstractTuned mass dampers may be used to improve vibrational behavior of structures. However, they require space to move. This paper presents an approach to incorporate tuned mass dampers into a lightweight-optimized structure without extra space requirement. It is based on (1) topology optimization (TopOpt) with unit cells and (2) vibration reduction with multiple tuned mass dampers (m-TMD) within the unit cells. The topology optimization is performed with a physics-informed penalty factor, unique to the chosen unit cell. Subsequently, the weight optimal density distribution is realized by populating the design domain with unit cells of ten different densities. To reduce the induced vibration, m-TMDs are placed inside the cavities of the unit cells in the grey scale regions. The effectiveness of the approach is demonstrated for the design of a 2-segment robot arm. The resulting unit cell robotic arm (UC-Arm) is 3.6% lighter than the reference model, maintains the same static performance, and shows a 60% smaller dynamic displacement in the observed frequency range. No extra space is required for the motion of the m-TMD.

Published: June 2023

AbstractProduct development stages are typically characterized by different forms of representations and degrees of specification, which potentially affect user's perception and evaluation. These effects are worth investigating more closely also because of the growing relevance of new technologies such as Virtual Reality (VR) in the design field. The objective of this paper is to elucidate the mutual relations between forms of representation, visual behaviour, and people's evaluations. The focus is on differences between virtual and physical prototypes. In the illustrated experiment, participants visited a tiny house in an immersive VR (360° images acquisition). The results were compared with a past experiment where the physical prototype of the same product was similarly evaluated. The dwell times on Areas of Interest (AOIs) pertaining to the tiny house were compared and correlated to variables concerning subjective evaluations. The results show just a few similarities of visual exploration in terms of gazed AOIs. Substantial differences in terms of how the duration of gazing affects evaluations have been found too. The larger number of significant correlations between observations and evaluations in the virtual exploration emerged.
VISUALISING AND REVERGING: UNDERSTANDING THE INTERSECTION BETWEEN CREATIVITY AND VISUAL THINKING
Authors: Jansen Alix , Heijne Katrina , van Oosterom Iren , Gonçalves Milene 
Published: June 2023

AbstractWe investigate reverging - the phase between the diverging and converging steps in a creative process - in the context of a visual thinking agency. Creative facilitation literature advocates for such a phase, aimed at revisiting and rearranging ideas generated during diverging, to prepare for converging. However, in practice this step is often neglected or not performed well, resulting into a sense of increased complexity or lack of client ownership.Two studies were used to investigate reverging in context: a preliminary study consisted of interviews and observations to better understand reverging in current visual thinking practices. The follow-up study focused on co-creating a tool to solve the problem identified in the preliminary study.While the preliminary study revealed the need to involve clients in both diverging and reverging phases, the follow-up study resulted in the creation of the Whiteboard Canvas. The tool was tested in practice and several benefits of reverging in visual thinking practices emerged.The tool empowers visual thinking practitioners to involve their clients more actively in reverging, resulting into a more deliberate creative process and an increased sense of client ownership.

Published: June 2023

AbstractDigital media are a means to deliver products and services, but also a channel to interact with consumers and a source of information on users’ preferences. Data shared by customers on the web, the User-Generated Content (UGC), can give entrepreneurs a detailed perspective of the market. This work examines an application of Natural Language Processing techniques on UGC to discover insights on users' opinions. We collected more than 13.000 reviews of software from digital stores and review website to gather information on the customers’ perspective and their response to a given marketing strategy in two case studies on digital product's launch. The objective is to give support to two Italian companies in the process of business model development through data-driven evidence. We aim to discover who are the users and which are their needs using a lexicon-based approach to mine unstructured text. The results provide qualitative and quantitative descriptions of the market segments. We propose a method to examine UGC and to explore customers’ behavior on social media. The findings helped managers for the development of their business model, enhancing an informed decision-making process.
WHEN IS A ROBOT A COBOT? MOVING BEYOND MANUFACTURING AND ARM-BASED COBOT MANIPULATORS
Authors: Guertler Matthias , Tomidei Laura , Sick Nathalie , Carmichael Marc , Paul Gavin , Wambsganss Annika , Hernandez Moreno Victor , Hussain Sazzad 
Published: June 2023

AbstractCollaborative robots (“cobots”) have attracted growing attention in academia and industry over the last years. Due to in-built safety features and easy programming, they allow for close human-cobot collaboration and support e.g. flexible manufacturing. However, the lack of a common understanding what a cobot is along with its traditional focus on arm-based cobots complicates further research and industry adoption. Thus, this paper analyses the variety of definitions in literature incl. standards and practice examples to derive a consistent and holistic definition and taxonomy of what a collaborative robot is. Aside from contributing a structured overview of various forms of human-robot collaboration, this builds an important foundation for future research as it systematically differentiates different cobot types. Companies and other organisations will benefit by a better understanding of what type of cobot they need and how to ensure safe collaboration.
WORK IN PROGRESS: DEVELOPMENT OF EDUCATIONAL KIT FOR TEACHING ADDITIVE MANUFACTURING
Authors: Valjak Filip , Kapetanović Ana , Taradi Ivona , Bojčetić Nenad 
Published: June 2023

AbstractAdditive Manufacturing (AM) is a unique manufacturing technology that is being rapidly accepted in various industries, leading to increased demand for experts who know to work with AM and how to design AM products. This led to a broader adaptation of AM in an educational context with various research on how to teach AM. However, most approaches are focused on teaching advanced AM application and Design for AM (DfAM), including both restrictive and opportunistic approaches, with little attention to specialised educational tools to show and teach the basic principle, possibilities and characteristics of AM. This paper presents the development of an Educational Kit for AM to address the gap and help teachers to explain the basics of AM, with a current focus on the material extrusion process. The Educational Kit is made of 17 models and accompanied cards explaining the essential characteristics of AM through short textual explanations, graphics, examples and manufacturing data. The Educational Kit for AM is intended to be used in introductory lessons on AM, so the novices in AM can quickly grasp the characteristics of AM and the basic terms used in AM before advancing to other AM and DfAM topics.
WORKING AGILE TO SPEED UP RESEARCH WITH INDUSTRY: FIVE INDEPENDENCE PRINCIPLES
Authors: Panarotto Massimo , Isaksson Ola , Söderberg Rikard 
Published: June 2023

AbstractOne of the obstacles to the ability of research to make an impact on industry resides on the research process itself. Today, there is a need to accelerate the means for research to support industrial transformation. At the same time, there is the need to maintain scientific rigorousness, which often requires time. To solve this trade-off, this paper evaluates existing research approaches through the lenses of agile development. The analysis is based on a simulation of research process architectures, and on observations made over several research projects with industry. The results of this analysis highlight five light-but-sufficient rules of research project behavior to keep momentum, motivation and trust when doing research with industry. The paper demonstrates the use of these five rules in a “research sprint” conducted iwith two automotive OEMs.
