EXPLORING SYSTEMIC FORCES THAT INFLUENCE SUSTAINABLE DESIGN TRANSITIONS
Authors: Watz Matilda , Hoffenson Steven , Hallstedt Sophie. I. 
Published: August 2021

AbstractIn this research some systemic forces to sustainable design are described and mapped out, along with key areas, dimensions and stakeholders. These results are visualized in a causal loop diagram (CLD), which was the outcome of a group model building approach supported by a literature review. Within the proposed system model, represented by the system-level variables and their relationships within the CLD, some potential leverage points that can help make product design better contribute to sustainability are identified and described. These can be found in the balancing and reinforcing feedback loops of the CLD as well as the mapping to societal dimensions of sustainability transitions and stakeholder groups. Among the stakeholder groups, business managers, scientific researchers and engineering designers can be tied to the design community. Future research is proposed to build on these initial results to deepen the knowledge about the systemic drivers and barriers and leverage the contribution of design practice to sustainable development.
EXPLORING THE COMBINED USE OF SOLICITED DIARIES AND PHOTOGRAPHY BY OLDER PATIENTS IN THEIR PROCESS OF SELF-CARE WITH MEDICATION PACKAGING
Authors: Carli Lorenzini Giana , Olsson Annika 
Published: August 2021

AbstractDesign has the potential to include or exclude people, depending on how user needs are translated into products. Design exclusion has been vast in design for health care. Medication packaging design is a common example. It does a good job of protecting the product but can result in creating difficulties when used, especially for those who are older. Research in this area lacks an inclusive and user-centered approach because potential users have been studied outside of their context of living and with methods that limit participation. The aim of this study was to explore the combined use of solicited diaries and photography to engage and include older users in gathering data and reflecting on their day-to-day experiences of using multiple medications and the medication packaging. Our findings show key learnings of using this combined method, as well as related methodological challenges, and provide recommendations to tackle these challenges. The use of solicited diaries with photographs taken by participants is deemed to be relevant in interdisciplinary fields of research and practice, where designers and other professionals aim to better understand the reality of older people and create meaning in their experiences of self-care.
EXTENDED TARGET WEIGHING APPROACH (ETWA): IMPACT AND RISK ANALYSIS OF LIGHTWEIGHT CONCEPTS IN THE PRODUCT-PRODUCTION SYSTEM-CO-DESIGN
Authors: Albers Albert , Stürmlinger Tobias , Revfi Sven , Behdinan Kamran 
Published: August 2021

AbstractLightweight design in interconnected systems becomes more and more complex as the interdependencies cannot be overseen by the product developer. Varying one component might not only influence the interfaces to other components but also the underlying production systems.Therefore, this contribution focuses on the product/production interdependencies and how they can be supported within lightweight design. Based on a functional description of the product it is possible to derive new lightweight design solutions and also to evaluate the change propagation in the production system. For this, a method for the impact and risk analysis is integrated in the lightweight design method Extended Target Weighing Approach (ETWA). By doing so, a risk value for the adapted production system can be calculated and different design concepts can be compared.The application of the developed method on a simplified use-case shows great potentials when evaluating the impact of a newly developed lightweight design solution on an already existing production system supporting the product development in decision making.
GEOMETRICAL BENCHMARKING OF LASER POWDER BED FUSION SYSTEMS BASED ON DESIGNER NEEDS

Published: August 2021

AbstractCommercially available metal Laser Powder Bed Fusion (L-PBF) systems are steadily evolving. Thus, design limitations narrow and the diversity of achievable geometries widens. This progress leads researchers to create innovative benchmarks to understand the new system capabilities. Thereby, designers can update their knowledge base in design for additive manufacturing (DfAM). To date, there are plenty of geometrical benchmarks that seek to develop generic test artefacts. Still, they are often complex to measure, and the information they deliver may not be relevant to some designers. This article proposes a geometrical benchmarking approach for metal L-PBF systems based on the designer needs. Furthermore, Geometric Dimensioning and Tolerancing (GD&T) characteristics enhance the approach. A practical use-case is presented, consisting of developing, manufacturing, and measuring a meaningful and straightforward geometric test artefact. Moreover, optical measuring systems are used to create a tailored uncertainty map for benchmarking two different L-PBF systems.
HANDLING OF EXPLICIT UNCERTAINTY IN REQUIREMENTS CHANGE MANAGEMENT
Authors: Gräßler Iris , Pottebaum Jens , Oleff Christian , Preuß Daniel 
Published: August 2021

AbstractInnovation projects are characterized by numerous uncertainties. Typical concepts in development management like the application of safety coefficients imply limitations of the solution space. In contrast, explicit handling of uncertainties can support engineers in understanding the problem space and in utilising the full potential of the design space along iterative product development steps. As a result from literature analysis, there is a lack of a support for product development that addresses the specific problem of uncertainty and risk in the context of requirement changes. The aim of the contribution at hand is to enhance the efficient development of complex interdisciplinary systems by enabling uncertainty handling in requirements change management. Based on a classification of uncertainty types resulting in a descriptive model, risk management measures are identified to support requirements engineers. The proposed method includes identification & modelling, analysis, treatment and monitoring of risks and counter-measures. By applying this method, engineers are supported in adopting agile approaches and enabling flexible Requirements Engineering.

Published: August 2021

AbstractThis is a qualitative single case study of a geographically distributed student team that experienced a quite different graduate course, compared to previous year's. This was due to the restrictions placed upon them following coronavirus lockdowns. With already ongoing research, and continuous development of the course, the authors had documented individual reflections and identified patterns and behaviours that seemingly determined the quality of the end result, as well as the students expectations and experiences. Semi-structured interviews, surveys and the author's individual reflection notes were already in place as part of the larger research scope and when the student team during the covid-19 year showed unexpected performance and results, the authors decided to pause the larger research scope and focus on this unique single case and capture those learnings. Not knowing how the Covid-19 situation evolves and leaning on insights from previous years, as well as this unique year, the aim with this paper is to describe the unique Covid-19 year amd share knowledge that can help improve and evolve the development of this longlived collaborative graduate student course, and other similar distributed team contexts.

Published: August 2021

AbstractThis work aims to test Prosperity Thinking methodology in Action and assess whether this method would respond to the needs of designers, innovators, and change-makers that are willing to change the food system. Starting from the evolution of marketing design to human-centered design, we illustrate the importance of taking into account the planet's means in the design for Sustainability at the system level. We approached the problem starting from practice, with an Action Research Innovation Management Framework (Guertler, Kriz, and Sick, 2020). Results show that designers, innovators, and changemakers have an interest in a methodology that helps them to analyze and solve systemic challenges linking the micro (human) and macro (planet) through a participatory approach to achieve long-term impact of the designed solutions.
IDENTIFICATION OF OPTIMIZATION AREAS OF A TRANSTIBIAL PROSTHESIS THROUGH THE POTENTIALS OF ADDITIVE MANUFACTURING PROCESSES

Published: August 2021

AbstractAdditive manufacturing enables new possibilities for the design of end products. These are rooted in the potentials of the manufacturing technology, such as flexible, tool-free production. These potentials can be used for the economic and flexible production of customized products. To support the use of the potentials, a development method was created which identifies optimization areas within a product. Therefore, the complexity is reduced by using of product functions. Characteristic functions and structural configurations are used to identify optimization areas. This contribution describes the application of the new development method to an existing mechanical transtibial prosthesis. In doing so optimization areas are identified which may make use of the potentials provided by additive manufacturing. One area is the interface between the prosthesis and the ground. By analyzing walking environments and the gait cycle the need for walking assistance on deformable surfaces was identified. Significant improvements were achieved through a functional integrated, additive manufactured foot sleeve.
INITIAL CHARACTERIZATION OF NOVICE ENGINEERING DESIGNERS' CONSIDERATION OF CONTEXTUAL FACTORS

Published: August 2021

AbstractEngineering designers are encouraged to consider relevant contextual factors throughout their design processes. However, specific practices for incorporating context into design processes are lacking in the existing literature, and curricula related to the use of context during design processes is limited. As a preliminary step toward characterizing novice engineering designers' use of contextual factors, we qualitatively coded 10 mechanical engineering capstone design reports for contextual factors; half of the projects had domestic sponsors with varying themes, and the other half of the projects had international sponsors with a global health theme. Our findings showed that teams considered technological and institutional factors most frequently; other factors were considered less frequently. Global health themed design teams considered more contextual factors than non-global health themed teams. There was considerable variability among the contextual factors considered, as well as the stages during which they were considered. These outcomes have the potential to inform the development of pedagogical tools to support the acquisition of skills related to formally addressing context during engineering design processes.
INTEGRATED NATURAL RESOURCE AND CONSERVATION DEVELOPMENT PROJECT: A REVIEW OF SUCCESS FACTORS FROM A SYSTEMS PERSPECTIVE
Authors: Rajski Pauline Victoria , Papalambros Panos Y 
Published: August 2021

AbstractIntegrated Natural Resource and Conservation Development (INRCD) Projects is an umbrella term for a variety of Integrated Conservation and Development Projects (ICDPs), a concept first introduced by the World Wide Fund for Nature in the mid 1980s to target practice-oriented efforts in developing countries; and Integrated Natural Resource Management (INRM) research and development projects introduced as adaptive management for fisheries, wildlife, forest, and rangeland to target analysis-oriented efforts in developing and developed countries. Both efforts seek to balance economic development and natural resource conservation. This paper reviews the literature over the past four decades in an attempt to determine which planning and execution methods lead to greater success. A thematic analysis revealed three broad areas of importance: community inclusion and income diversification, inadequate training and management, and inability to properly quantify data. A systems design optimization approach for such projects is advocated to support project decision making in these areas of importance.
KNOWLEDGE-BASED EVALUATION OF PART ORIENTATION DESIRABILITY IN POWDER BED FUSION ADDITIVE MANUFACTURING

Published: August 2021

AbstractIn powder bed fusion (PBF) additive manufacturing, the definition of part orientation is one of the most important steps as it affects the quality, the cost and the build time of products. Different works already attempted to propose methodologies for the assessment of optimal build orientation based on criteria such as the minimization of support volume. Elicitation works with industry experts have shown that they use much more varied rules to determine the orientation of parts. For instance, they do not treat the different surfaces of the part the same way (e.g., experts state that “priority surfaces of the part must be oriented close to vertical”). Today, the available tools do not allow integrating these kind of specifications. This paper discusses a knowledge-based methodology for the evaluation of part candidate orientations in PBF. Desirability function approach is used to translate companies’ expertise in the form action rules into mathematical functions that are tested on geometries to provide metrics for assisting the decision-making. A case study is presented to illustrate the use of this desirability function approach on complex part orientation problem.
LIMITATIONS OF DESIGN SPACE-BASED INDICATORS FOR EARLY ROBUSTNESS ASSESSMENT
Authors: Juul-Nyholm Herle Bagh , Sigurdarson Nökkvi S. , Ebro Martin , Eifler Tobias 
Published: August 2021

AbstractThis paper seeks to address the gap between qualitative Robust Design principles and parameter optimization. The former often fails to consider the challenging amount of details in embodiment and configuration design, while the latter is the widely accepted main thrust in traditional Robust Design. The gap is addressed by exploring the value of five quantitative robustness indicators for Design Space Exploration based on variables, objectives and constraints: The set level indicators, Design Space Size and Pareto Set Dispersion, and the point level indicators, Neighbourhood Performance, Failure Rate and Distance to Failure. As a background for the discussion of the limitations of these indicators an industrial case is presented. The case is an incremental encoder and includes two configurations for comparison, five objectives, eight variables, and a range of constraints. The design spaces are sampled and they show conflicting objectives, dispersed spaces and variables dependencies. Based on this it is suggested that set level indicators are more suitable than point level indicators of early robustness evaluation, but the available indicators are limited in their considerations of design space discontinuity and conflicts.
MAPPING A SYSTEMS APPROACH TO EXISTING HEALTHCARE DESIGN, DELIVERY AND IMPROVEMENT METHODS
Authors: Günay Aslı , Ward James , Clarkson P John 
Published: August 2021

AbstractDesign, delivery and improvement processes in healthcare is of great challenge due to increasing pressures on healthcare systems alongside inherent complexities, resulting in limited benefits or unforeseen consequences. A recent Systems Approach framework has aimed at responding to the calls about implementing a more holistic approach. Though being an approach in its own right that can iteratively and systematically structure, guide, and/or facilitate design and improvement projects in healthcare, it can also augment existing approaches that have already place in healthcare designers' and improvement practitioners' agendas. Thus, the objective of this paper is to compare and contrast the questions, activities, and tools of the Systems Approach with processes of other major improvement approaches in healthcare to demonstrate their coverages, overlaps, and extended and new opportunities to pursue in the light of the Systems Approach.
METHOD ACCEPTED - FIELDS OF ACTION FOR INCREASING METHODS APPLICATION IN PRODUCT DEVELOPMENT
Authors: Wallisch Anne , Nicklas Simon J. , Paetzold Kristin 
Published: August 2021

AbstractContrary to all agreement that methods can efficiently support design activities in the product development process, it can still be heard that notably complex methods often find little acceptance in industrial practice in terms of consistent use. Therefore, this concept paper aims to identify factors influencing the formation of acceptance to support a successful design and implementation of methods in product development. For this purpose, the first necessary step is to clarify the conceptualization of acceptance within this domain. Furthermore, the influencing variables, which are described in the acceptance models having been identified as development-relevant in a literature review, are first extracted and second newly structured using a behavioural model reflecting the mental stages from stimulus to behaviour. Third, the insights gained towards the factors' relevance throughout these stages are applied to the conditions of method application in engineering and design. In a subsequent step, basic assumptions towards central fields of action for concrete measures to increase acceptance concerning the use of methods in product development are derived.
METHODOLOGY FOR A TASK-SPECIFIC AND PERSONALISED DEVELOPMENT OF AN INITIAL EXOSKELETON DESIGN
Authors: Drees Tobias , Kunnen Steffen , Pluhnau Robin , Nagarajah Arun 
Published: August 2021

AbstractThe use of exoskeletons promises improved ergonomics, empowerment of users and prevention of musculoskeletal disorders. However, the development process is complex and a generic development methodology that will guide and assist designers through it is missing. The goal of this paper is to describe a methodological approach that will assist the conceptual design of exoskeletons. Based on derived methodological requirements, activities 1, 2, and 3 of the VDI 2221 (Methodology for the development of technical products) are specified to adapt the generic guideline to the development process of exoskeletons. These activities include the analysis and determination of the relationship between the use case, product requirements and motions, technical functions, and design solutions. For generating a list of product requirements designers must focus on the workers’ motions and needs for a for a task-specific and personalised development. Use case specific movements are generalised by using rotational and translational basic movements that result in six degrees of freedom and from which a function structure is derived. The method is critically reviewed based on the established methodological requirements.
MITIGATING COMPANY ADOPTION BARRIERS OF DESIGN-DRIVEN INNOVATION WITH HUMAN CENTERED DESIGN
Authors: Baha Ehsan , Ghei Taresh , Kranzbuhler Anne 
Published: August 2021

AbstractIn Design-Driven Innovation (D-DI) the meaning of a product or service is radically innovated to introduce a new paradigm that ideally can benefit people, companies, and society as a whole. However, due to the associated risks, most companies are hesitant to engage with and adopt D-DI. Human Centered Design (HCD) is preferred while innovation is limited to incremental change. This dichotomy is also reflected in design literature where D-DI is pitted against HCD. We propose the symbiosis of the two approaches as a strategy to create space for and the adoption of D-DI within companies. An instrumental design case study explores a design-driven service innovation and its adoption in a renowned airline. Results show an adopted D-DI where HCD evidence mitigates for the market and organization uncertainty while D-DI enabled a paradigm shift in the company’s current service operation. Advantages and limitations of this mitigation strategy are discussed. With this design precedent, we aim to encourage designers and companies to further explore the benefits of a symbiotic use of D-DI and HCD.

Published: August 2021

AbstractIn the medical education field, the use of highly sophisticated simulators and extended reality (XR) simulations allow training complex procedures and acquiring new knowledge and attitudes. XR is considered useful for the enhancement of healthcare education; however, several issues need further research.The main aim of this study is to define a comprehensive method to design and optimize every kind of simulator and simulation, integrating all the relevant elements concerning the scenario design and prototype development.A complete framework for the design of any kind of advanced clinical simulation is proposed and it has been applied to realize a mixed reality (MR) prototype for the simulation of the rachicentesis. The purpose of the MR application is to immerse the trainee in a more realistic environment and to put him/her under pressure during the simulation, as in real practice.The application was tested with two different devices: the headset Vox Gear Plus for smartphone and the Microsoft Hololens. Eighteen students of the 6th year of Medicine and Surgery Course were enrolled in the study. Results show the comparison of user experience related to the two different devices and simulation performance using the Hololens.
ON FORMATION OF STRUCTURES: DESIGN EXAMPLES AND DISCUSSION
Authors: Hou Yuemin , Ji Linhong 
Published: August 2021

AbstractThis paper discusses the formation of structures by taking the process of gene transcription and translation as the template. The hypothesis of this paper is that the gene transcription and translation process can describe the formation of structures both in engineering design and in biology. The paper first presents design examples including integrated circuit (IC) chambers, flapping wings of bird robots, and typical mechanisms and formulate the formation patterns of the design process as four steps: information interpretation, selection of building blocks, the connection of building blocks, and formation of structures. The key step of the formation process is to assemble building blocks for structures both in engineering and in biology. Building blocks in biology are amino acids while they are structures in design. The autonomous degree of the formation process depends on the level of building blocks. The reuse degree of the building blocks depends on the level of building blocks too. In biology, structures of proteins are self-organized, so one way towards design automation is to use lower-level building blocks.
