OBSERVATIONS ON THE IMPLICATIONS OF GENERATIVE DESIGN TOOLS ON DESIGN PROCESS AND DESIGNER BEHAVIOUR
Authors: Saadi Jana , Yang Maria 
Published: June 2023

AbstractDevelopments in artificial intelligence (AI) are opening the possibilities for the development of more advanced design tools. An example of these innovations are generative design tools, in which the generation of complex and high performing products is possible. This study investigates the use of generative design tools and how they may influence the design process and designer behaviour. Six interviews of interdisciplinary designers were conducted to understand the implications of using generative design tools. It was observed that generative design tools primarily allow for quantitative inputs to the tool while qualitative metrics, such as aesthetics, are considered indirectly by designers. The subjectivity of the designer and how they incorporate the quantitative and qualitative metrics in the generative design tool can lead to differing outcomes between designers. Notable differences in tool usage are also observed between expert and novice computational designers. Additional studies should be conducted to further understand the extent generative design tools impact the design process, designer behaviour, and design outcomes.
ON THE TREATMENT OF REQUIREMENTS IN DFAM: THREE INDUSTRIAL USE CASES
Authors: Endress Felix , Rieser Jasper , Zimmermann Markus 
Published: June 2023

AbstractOptimization-driven design offers advantages over traditional experience-based mechanical design. As an example, topology optimization can be a powerful tool to generate body shapes for Additive Manufacturing (AM). This is helpful, when (1) load paths are non-intuitive due to complex design domains or boundary conditions, or (2) the design process is to be automated to minimize effort associated with experience-based design. However, practically relevant boundary conditions are often difficult to put into a formal mathematical language to, for example, either feed it into a topology optimization algorithm, or provide precise quantitative criteria for CAE-supported manual design. This paper presents a survey of three industry use cases and identifies three types of requirements: the first can be directly cast into parts of an optimization problem statement (∼ 40%), the second is considered indirectly by adapting the optimization problem without explicit reference to the requirement (∼ 20%), and the third is only assessed after the design is finalized (∼ 40%). For categories 2 and 3 we propose directions of improvement to support formulating complex design tasks as unambiguous design problems.

Published: June 2023

AbstractThe product engineering process as part of the product life cycle includes product and production system development as well as production. In integrated product and production engineering (PPE), knowledge transfer is an important success factor. Optimizing the efficiency and effectiveness of knowledge transfers can, for example, support the avoidance of costly, production-related changes to the product design. The current state of research describes different models of knowledge transfer as well as factors that influence it. Some results show how the speed and quality of knowledge transfer can be improved by implementing so-called interventions. However, those models either represent abstract contexts of knowledge transfer or focus only on product engineering. Therefore, a literature analysis is conducted to identify the system of objectives for a method, that supports the improvement of knowledge transfer in PPE. Subsequently, the system of objectives is operationalized to provide the basis for the InKTI – Interdepartmental Knowledge Transfer Improvement Method, which is applicable, supports the user in improving knowledge transfers in PPE, and aims to increase the quality and speed of knowledge transfers.

Published: June 2023

AbstractThe transportation sector is responsible for a relevant share of the total emissions and offers great potentials. It is necessary to implement as many zero-emission mobility systems as possible in the shortest time. For fast ferries, which are a relevant transport manner for a large share of the global population, technical issues could be solved and the successful operation was demonstrated. Up to today high-speed ships have been fully individually designed because physical effects demand for an individual optimisation for each use-case. Specifically for battery electric ships the overall efficiency is crucial to ensure not only an ecological but also economical operation.With today's methods the design and production of such an individual designed ferry does take too long. To cover the rising demand, new approaches for mass production need to be established.In this paper we describe a method for designing a platform for ships with the example of a battery electric fast ferry. The focus is on the actual modularisation, as other aspects like requirements or results of our example case are published elsewhere and are therefore just included briefly.The method is validated on the world's first battery powered high-speed ferry.
PREVENTING THE OVERCONSUMPTION AND DISPOSAL OF REFILL AT HOME FAST-MOVING CONSUMER GOODS – INTERVENTIONS THAT SUPPORT CIRCULAR CONSUMER JOURNEYS
Authors: Tassell Catriona , Aurisicchio Marco 
Published: June 2023

AbstractContext and problem: Reuse is positioned as a strategy capable of countering single-use overconsumption and disposal. For refill at home FMCGs, consumers are responsible for carrying out behaviours that enable this, such as keeping and using products for a prolonged period. However, it is not known if consumers actually fulfil these responsibilities. Aim: This research aims to understand the extent to which consumer reuse behaviours supports the intended reduction in impact and, if not, consider how best to improve it. Method: In-depth interviews with 15 consumers were conducted where the behaviour chain method was used to map resource journeys for 31 refill at home offerings. Results: Five models of consumer behaviour increased the impact of reuse. The critical moments which led consumers to carry out these behaviours were identified, uncovering intervention areas. Conclusions: The behaviour models and critical moments offer a first attempt to systematically analyse how and where actual consumer behaviour can increase the impact of refill at home FMCGs. The results call for focussed interventions across the consumer journey that support reuse components as part of a system.

Published: June 2023

AbstractThe climate change and the new regulations imposed to slow down this process have pushed major actors around the world to apply sustainable measures in order to meet governmental obligations. The packaging industry has a major role in fighting climate change and the environmental social and financial disasters. In fact, packaging requires substantial number of natural resources and is often disposed of in ways that harm the environment. Supply chain managers realized that packaging design is the root to solve all the problems packages create throughout their entire life cycle. Therefore, a thorough study about influencing the design process should be prioritized. This paper provides a systematic review of industrial packaging eco-design applied to the supply chain. It aims to conceptualize the definition of industrial packaging eco-design and supply chain sustainability to categorize main parameters to its implementation and to identify the limitations of current research and its prospects.
REDUCING PROTOTYPE FABRICATION TIME THROUGH ENHANCED MATERIAL EXTRUSION PROCESS CAPABILITY

Published: June 2023

Abstract3D printing is a widely used technology for automating the fabrication of prototypes. The benefits are wide reaching, and include low required expertise, accurate geometric form and the processibility of many materials. However, production of certain forms – especially large forms – can be slow. From review of the sub-systems, the hotend is commonly found to be the limiting factor. To improve this, a modified nozzle design is considered that incorporates a flat copper plate within the flow stream. Analytical simulation was used to guide this design before experimental methods validated the modifications. The maximum volumetric rate for the standard hotend nozzle is 14 mm3/s. The best performing modified nozzle increased the maximum volumetric flow rate to 26 mm3/s – an 86% increase. A series of popular parts were further considered, demonstrating a maximum ∼48% fabrication time reduction, and a mean of ∼23%. This enables 3D printed prototypes to be made more efficiently – both with regards to the design cycle and energy use – and allows designers to use the technology more rapidly than previously possible. By extension, this improves the efficiency of the design process.

Published: June 2023

AbstractProduct design is one of the key features of intellectual and creative abilities of humans. Activities of product design have attracted not only experts, but also those without any design training. Many people - working in metalworking microenterprises in the informal sector of developing countries - engage in the activities of designing and manufacturing products. However, since extant design research is mainly undertaken in developed countries, there is scarce knowledge about design activities in informal metalworking microenterprises in developing countries. This paper aims to address this issue by uncovering some aspects of design processes in such microenterprises. In particular, we explored: various product attributes that these microenterprises consider in designing products, the process steps they follow in requirements identification and solution generation, and resources (e.g., design methods, training, etc.) available to them. To explore these aspects, we conducted semi-structured interviews in 24 informal metalworking microenterprises in Tanzania. The findings have important implications for supporting their design activities.

Published: June 2023

AbstractThe design of Product-Service Systems (PSS) is challenging due to the inherent complexities and the associated uncertainties. This challenge aggravates when the PSS being considered has a longer lifespan, is expected to encounter a dynamic context, and integrates many novel technologies. From systems engineering literature, one of the measures for mitigating the risks associated with the uncertainties is incorporating means in the system to change internally as a response to change externally. Such systems are referred to as value-robust systems, and their development largely relies on Tradespace exploration and synthesis. Tradespace exploration and synthesis can be challenging and a time-consuming task due to dimensionality. In this light, this paper aims to present an approach that enables the population of the Tradespace and then, supports the synthesis of such a Tradespace using a clustering algorithm for support changeability quantification in PSS. The proposed method is also implemented on a demonstrative case from the construction machinery industry.

AbstractSystems Engineering (SE) is becoming increasingly relevant in industrial application since more stakeholders are involved in engineering activities. To implement SE, companies have to adapt existing engineering processes and methods. This adaption requires knowledge about new methods as well as their integration into the engineering activities. In order to ensure goal-oriented identification of methods for different SE activities in this contribution an action field profile and the Systems Engineering Method Matrix are proposed. The development of both tools is driven by the assumption that most SE activities and methods can be described based on the artefacts the deliver. In order to get feedback about the proposed tools, semi-structured interviews with two industry partners were conducted, focussing on the tool's usability. These interviews underline the basic usability of the tools and their support to identify SE activities to be supported by (new) methods. Moreover, requirements for further development and adaption are derived from the interviews.
SYSTEM VALUE ANALYSIS: MODEL AND EXAMPLE
Authors: Lavi Emilia , Reich Yoram 
Published: June 2023

AbstractSystems design, being a socio-technical discipline, is highly affected by available technologies, the global economy, the state of the environment, and social issues. Hence, in recent years, the ultimate objective of design started to shift from best-performance systems to ones providing value to customers, enterprises, and society. This paper presents a holistic concept of system value, equipping the stakeholders participating in the design process with a broad view of this measure. The contribution of this paper includes a proposal for general system value taxonomy, which can be used as a foundation for a comprehensive, case-specific, system value model (SVM). As an all-round perspective of value is possible only when all stakeholders are represented, we suggest deploying the PSI framework for mapping the relevant stakeholders. The system value analysis of Tesla's Model Y electrical vehicle is demonstrated, as a test case for SVM application. We conclude that a detailed analysis of SVM, performed by a carefully chosen group of diverse stakeholders, highlights less conventionally discussed aspects of the system during design decision processes, hence is expected to improve the system's overall value.
THE SITUATEDNESS OF DESIGN CONCEPTS: EMPIRICAL EVIDENCE FROM DESIGN TEAMS IN ENGINEERING
Authors: Gero John , Milovanovic Julie 
Published: June 2023

AbstractSituatedness in design suggest that designing is situated within the design process or the cognitive actions taken by the designer, the designer's expertise and know-how, the designer's experience generally and the interactions in the specific design task being undertaken as well as the interactions with the design artefact generated. In this paper, we analyzed the situatedness of design concepts generated by teams of professional engineers during a design task. The method combines protocol analysis, Natural Language Processing and network theory to provide a representation and a measurement of design situatedness overtime. Providing empirical evidence of the situatedness of concepts has been overlooked in design research. The method and results presented in this paper outlines the foundation to empirically explore design situatedness.
THE SYSTEMATIC FEEDBACK METHOD FOR IDEATION MODE IN WORKSHOPS
Authors: Akaki Mayu , Maeno Takashi 
Published: June 2023

AbstractTo encourage creativity through ideation mode in design thinking, we conducted three workshops dealing with regional challenges with 44 participants. The systematic feedback method applied to the workshops supports the multi-disciplinary participants to feedback during the ideation mode to diverge ideas from diverse perspectives. The method is composed of feedback cards and the process of using them. Two kinds of cards encourage communication within the team. The next three cards aim to diverge the viewpoints of the feedback systematically to support the team to imagine the possibility of the idea evolving from a bird's eye view.Through quantitative analysis of the survey, we identified the significant and positive correlations between acceptance of the team's idea and team creativity, the effectiveness of the method on team creativity, and the team's characteristics that firmly realized the effect of the method. By categorizing the free comments, we indicated the valid functions and improvements that need further research in the future. Identified valid functions were not only diverging minds and perspectives but encouraging communication and understanding of the team members leading to acceptance and creativity.

Authors: Heikkinen Teuvo , Juuti Tero 
Published: June 2023

AbstractResearch on partly configurable products is emerging. Key concepts of these types of products have been scarcely synthetized, as definitions of partly configurable products in high-variety, low-volume industrial context are limited. These products incorporate modular and integral designs, which calls for an overview on the relations of key concepts defining them. The problem is approached through an exploratory literature review, which allowed an overview of the key concepts over product modularity and partly configurable products. Those were synthetized further define partly configurable products. As a result, four types of partly configurable products are given. This review supports vantage over the key concepts and their relations for reuse with partly configurable products in academia. For practitioners the presented attributes and given examples support in understanding of concepts and their relations with partly configurable products.

Published: June 2023

AbstractResilience is a widely studied concept that is a key objective in the design and development of sustainable systems. This is especially true for the agricultural systems critical to food production, economic viability, and sustainability of our communities, as farmers seek to meet increasing demand in the face of shocks such as climate change and natural disasters. Although there is a rich body of work examining resilience, there is limited understanding of how the concept of resilience should be tailored for agricultural systems. This study seeks to address this gap by performing a systematic literature review of 50 papers selected from SCOPUS using the PRISMA protocol. A summary of research topics and characteristics by geographical region is presented. The paper also categorizes the types of shocks studied and the corresponding response methods. Results suggest that the focus of resilience research changes by region, which may indicate that design strategies and objectives should also differ by region. Furthermore, the work identifies a need for more simulation-based quantitative research into the impact of resilience.
UTILIZING THE EMBODIMENT FUNCTION RELATION AND TOLERANCE MODEL FOR ROBUST CONCEPT DESIGN

Published: June 2023

AbstractThe early use of Robust Design (RD) supports the development of product concepts with low sensitivity to variation, which offers advantages for reducing the risk of costly iterations. Due to the lack of approaches for early evaluation of product robustness, the embodiment-function-relation and tolerance (EFRT-) model was developed, which combines the contact and channel approach and tolerance graphs. The information exchange of both approaches offers a high potential for reliable robustness evaluation results. However, that potential currently relies unused, since the link between applicable robustness criteria and the extended information is missing. To solve this problem, four research steps were determined: (1) understanding of robustness, (2) collection of RD principles, (3) identification of EFRT-model information and (4) mapping of RD principles and information. The results show nine adapted RD principles, the identified model information for the robustness evaluation, the evaluation criteria as well as their mapping. Utilizing the mapping and the proposed criteria in this contribution, a more comprehensive robustness evaluation in early stages is enabled.

Published: June 2023

AbstractStakeholder perspective taking is a critical skill in early-stage problem exploration and framing. We examined stakeholder perspective taking within an early-stage design team of engineers at NASA to begin to understand in what ways and under what conditions designers adopt stakeholder perspectives in the context of professional engineering organizations. Our findings identify a spectrum of perspective taking during problem framing deliberations that ranges from (1) fully taking the stakeholder's point of view (POV), (2) interpreting the stakeholder's POV using the designer's POV, (3) implanting the stakeholder's POV into the designer's POV, to (4) fully taking the designer's own POV. We also identify and describe conditions that appeared to encourage or hinder perspective taking in this setting. These findings are significant because they suggest ways to gauge and encourage the skill of stakeholder perspective taking among professional engineers working on real-world design challenges with societal implications.
ALIGNING FUNCTIONAL ANALYSIS PROCESSES WITH DESIGNERS' NATURAL COGNITIVE FLOW
Authors: Reeling Hunter Scott , She Jinjuan 
Published: June 2023

AbstractEngineering design in new product development is a constant battle between creativity and strict structure. As researchers look to optimize the process, each stage is placed under a microscope to put designers in the best position to develop better products for companies in a cost effective manner. One idea in improving product development is the concept of incorporating the Human-centered Design into functional analysis. However, critiques of these functional analysis methods cite an unnecessary amount of resources needed to invest in these steps, a restriction in creativity, and a high necessary level of effort from the design teams. The goal of this research will be to address these critiques by incorporating theories from cognitive research and Human-centered Design into the functional analysis process. This work will propose a new method aimed to improve the quality of the function model of the design space, increase the creativity freedom of the designers, and be accessible to engineering students and industry engineers alike.
