DEALING WITH EXTREME REQUIREMENT VALUES: WHAT METHODS TO DESIGN SCHOOL CHAIRS AND OFFSHORE WIND TURBINES HAVE IN COMMON
Authors: Haselsteiner Andreas Florian , Thoben Klaus-Dieter , Blessing Lucienne 
Published: June 2023

AbstractMany designs are “driven” by requirements that describe maximum or minimum values of high- variability variables that must be considered. In ergonomics, minima and maxima of anthropometric variables like body height shape the design of a product. Similarly, in structural design, the highest environmental loads that can be expected during the lifetime of a product drive the design. Consequently, a wide range of methods that help designers deal with extreme requirement values has been developed. In this paper, we review these methods and propose a model for the process of dealing with extreme requirement values. The model comprises two broad stages. In the first stage, requirement values are statistically defined and in the second stage, a design is synthesized and evaluated against the requirement values. Throughout the paper, we use two examples: the design of an ergonomic chair and of an offshore wind turbine. We focus on how requirement values are defined for these two products and how they are used throughout the design process. Although these products are vastly different, both are designed by statistically deriving requirement values and then systematically designing against these values.

Published: June 2023

AbstractEndotracheal intubation is performed to provide ventilatory support to a patient of any age. Every medical procedure that requires general anesthesia requires intubation, and for this reason, it is a life-saving procedure. This maneuver is a challenge in pediatric patients between 0 months and 12 years of age, since their anatomy and oxygen consumption differ compared to an adult.In patients with difficult airways, where there is no good visibility of the structures, a videolaryngoscope is used. It has higher success rates compared to a conventional laryngoscope. Its use has become widespread since the COVID-19 pandemic, as it reduces exposure to respiratory secretions.This article presents the design, manufacture and testing of a low-cost pediatric videolaryngoscope, for patients between 6 and 12 months, and which are intended to respond to the low availability of this type of equipment in Colombian health care centers. The BioDesign Innovation Process methodology was adapted for its creation. The prototypes were manufactured using 3D printing. Validation was performed by 28 experts using simulators and the results were promising, obtaining a success rate of 98.8% for the designed device.

Published: June 2023

AbstractIn the IT landscape, DevOps is the preferred approach for developing and maintaining rapidly evolving systems that require continuous improvements. Yet, DevOps frameworks do not entirely prevent the accumulation of Technical Debt (TD), and under certain circumstances DevOps can even contribute to generating TD. This paper focuses on a specific type of TD, Entangled Technical Debt (ETD), that corresponds to the implicit complexification of a system's design and the appearance of unintentional couplings in its architecture over time. Our work seeks to inform methods for Diagnosing and Locating ETD in DevOps frameworks. Through a research partnership with Ubisoft's IT branch, an experimental case-study was conducted. It takes the form of an assessment of 6 innovative IT projects and a subsequent in-depth architecture analysis of an individual IT system, which enabled the characterization of the mechanisms linking DevOps to ETD. This allowed us to develop and test practical methods for diagnosing and locating ETD in IT systems.

Published: June 2023

AbstractHumans are able to perform skilful movements by coordinating muscles throughout the body. It has been revealed that not only neural mechanisms but also direct and dynamic interactions between body parts contribute to muscular coordination. Tensegrity, accurately biotensegrity, can be considered to the basic mechanism for the interactions. Tensegrity structures are composed of tensile and compressive components, and are lighter and more flexible than existing rigid structures. The authors investigated designing wearable tensegrity structures for extending human motor ability, especially assisting in carrying heavy objects. Based on Flemons' spine model, we devised a columnar tensegrity structure that can be expanded to the size of the whole body, and connected each of four columns to the front and back of the body on right and left side. The wearable tensegrity structures can deform flexibly due to tension distribution when external force is applied, and follow the human motions in twisting trunk and walking. Experimental results in carrying heavy objects showed that some muscle activities around hip and knee tended to decrease by using the structures when those joints extended.

Published: June 2023

AbstractDigital Twins are one of the most trending topics. However, there are still open issues in the development of Digital Twins. One of these impediments is formulating a clear and valid value proposition of a Digital Twin. Therefore, this paper presents a novel business modelling approach for Digital Twins. Based on a literature review and an academic case study, different business modelling approaches and techniques were systematically compared, selected and adjusted in order to develop a new framework suitable for describing the value of Digital Twins. It consists of 10 steps – (1) describe a basic development concept of the DT, (2) identify the customer segments, needs and pain points, (3) derive a value proposition (4) identify revenue streams and values created, (5) identify key activities, (6) resources needed, and (7) necessary partners. (8) Adapt the organization to fit the business model and (9) evaluate the cost structure of the project. In the end, document and communicate the new business model (10). Each step is supported by auxiliary methods, tools and procedures. The approach was applied to a scientific case study. In an initial evaluation the overall applicability and usefulness of the approach were confirmed.

Published: June 2023

AbstractEnvironmental sustainability represents an unavoidable design driver. The consciousness of the importance of tackle the topic of environmental sustainability since the first stages of the product lifecycle is slowly spreading through enterprises. However, although they reach this grade of awareness, it is hard to introduce additional considerations to the traditional drivers of functionality, manufacturability, assembly, cost, etc. Therefore, it is crucial to identify methods and tools to support companies in efficiently integrating environmental sustainability issues in their design process. This paper proposes an approach to identify the inputs, functionality and outputs suitable to each industrial reality. Its core is the eco-design tool matrix, that estimates the tool implementation time and suggests proper outputs; from this the necessary inputs and functional blocks are derived. The approach is applied to the cases of two Italian industries, very different one another. This proves the wide applicability of the approach. The definition of a validation procedure represents the next steps to identify the benefits of the approach.
DESIGN SPRINT: USE OF DESIGN METHODS AND TECHNOLOGIES

Published: June 2023

AbstractThis paper analyses the use of design methods and information and communication technology (ICTs) tools in design sprint (DS) activities. Team members, team leaders, and coaches of five international student teams were interviewed (40 interviews in total) regarding their use of design methods and ICT tools during three DS activities: problem definition, conceptual design, and embodiment design. The results show that teams utilise various methods through three approaches: one method for the task, several methods for the task, or adjusting methods. Teams considered several aspects when deciding which method to utilise: the possibility of work distribution, the time needed to execute the method and their prior experience in using the method. The results on using ICT tools suggest that teams mainly use the collaborative whiteboard and Computer-aided design (CAD). In this context, tools that enable continuous sharing of the work in progress (e.g., cloud-based tools) show great potential for DS activities. Finally, the results show a potential to integrate various tools in order to enable easy transition between tasks (e.g., a transition from collaborative whiteboard to CAD modelling).
DESIGNING FOR HUMAN FACTORS: DEVELOPMENT AND EVALUATION OF A HARMONISTIC KNOWLEDGE-BASED DESIGN DECISION SUPPORT TOOL
Authors: Agius Sean , Farrugia Philip , Francalanza Emmanuel 
Published: June 2023

AbstractDual ontological products are a physical construction and an emotional construction. Multitude of human factors must be considering when designing dual ontological products. To increase the product's impact and reach, designers should also understand the requirements of potential users. A design stage conflict exists between the emotional construction and the physical construction of a product when considering human factors. Designers find it difficult to achieve the right compromise between these constructions and hence, the balancing of the two is crucial. This research therefore contributes a novel harmonistic knowledge-based framework which makes designers aware of design stage conflicts and consequences of commitments made on human factors in the use-phase of the artefact. This approach was implemented in a machine learning based computational tool which exploits harmonistic knowledge and information collected from potential users to proactively assist, guide, and motivate product designers. This paper also presents a descriptive study for the evaluation of the framework and its implementation as a computer-based prototype tool. Results show the necessity and beneficial use of the tool for design engineering practice.
DESIGNING SERIOUS GAMES TO UNDERSTAND THE CHALLENGES OF THE ANTHROPOCENE

Published: June 2023

AbstractThe challenges of the Anthropocene require a deep transformation of the world's economic organization. In order to manage such a change, it is necessary to have a systemic vision of the resources, processes at stake and their interdependencies. One possible approach to modeling part of this complexity is biophysical flow accounting. One of the challenges is to involve populations in participatory processes. It is therefore important to understand the systemic effects. However, biophysical accounting tools remain too complicated.This is why we have designed serious games to present the issues in a simple way, to articulate them with concrete experiences already lived by citizens and to take a step back, by mobilizing their participation, their emotions and the discussions.The first game was designed to show the geographical transfer of pressure through the description of the steps leading to the purchase of a chicken, starting with the vegetable culture allowing to feed it.The second game was designed to show the competition of use between resources. Designed as a board game, it also involves reflection on the cooperative and competitive aspects of many societal situations.
DEVELOPMENT OF A 2D BIOMECHANICAL MODEL TO SIMULATE SEATED MULTIDIRECTIONAL ARM STRENGTH OF PEOPLE WITH C5-C7 TETRAPLEGIA
Authors: Stilwell George , Symons Digby , Gooch Shayne 
Published: June 2023

AbstractPeople living with tetraplegia experience a significant loss of sensory and motor function; with the severity depending on their injury level and completeness. To complete tasks independently, people with tetraplegia often rely on assistive devices. To avoid upper extremity pain, designs should not require applications of force near the limits of the user's physical strength. This paper establishes a 2D biomechanical model using static equilibrium and joint torque limits to predict multidirectional strength patterns in the sagittal plane for people with C5 to C7 tetraplegia in a seated position. The results from the biomechanical model highlight the areas and directions of high strength. The strength patterns observed in this paper provide an opportunity for designers to evaluate strength requirements and take advantage of areas and directions of high strength and ensure that users are not required to apply force near their physical limit. In doing this, designs such as assistive devices can be developed that enable users with a reduction in strength to operate them independently.
DEVELOPMENT OF A NOVEL DIABETIC FOOT RISK ASSESSMENT FOR LOW-RESOURCE HEALTHCARE SETTINGS: A CASE STUDY OF LEAN DESIGN
Authors: Reddie Madison , Frey Daniel 
Published: June 2023

AbstractInterest in applying a “lean” philosophy to design has been slowly growing in recent years, but there are still few broadly applicable methodologies and illustrative cases published in the literature to guide lean design processes. Lean approaches promise cost reduction and increased product value, which could be particularly beneficial in product development for low- and middle-income country markets, where value demands are high. We use the clinical need of efficient diabetic foot risk assessment in lowresource healthcare settings to present an example of lean early-stage design of a medical device. The background of existing medical literature and commercial products is intentionally leveraged throughout the design process to streamline development and minimize the need for independent validation of product strategies and design features. Our approach resulted in an efficient design process that generated a novel, purely mechanical plantar pressure evaluation device that can indicate high risk of diabetic foot ulcer in resource-constrained settings. This case provides a practical example of how design processes can be adapted to be leaner where there are large gains from minimizing design cycle time and cost.
DIMENSIONS OF PRODUCT COMPLEXITY FROM DESIGNERS’ PERSPECTIVES
Authors: Holliman Alexander ′Freddie′ 
Published: June 2023

AbstractThe perceived complexity of a product (product complexity) is doubtless an influential phenomenon in a design project. Insight into this factor and how it can be measured, is key to understanding its influence, supporting project planning and resource demand estimation. Opinions on product complexity vary greatly, with many definitions, scales and techniques to measure product complexity available; many of which draw their conclusions from engineering design research. Yet the field of product (or industrial) design companies, whose designers work across a vast range of product types, from domestic to industrial remains under researched. These designers have a tacit understanding of many influences over their projects, of which product complexity is one.This paper presents an analysis of the dimensions (or measures) of product complexity found in literature and compares its findings to the measures defined by practicing product designers. This paper will demonstrate the process used to identify these dimensions and the scales developed to assess product complexity in a practical way and will make conclusions on the perspectives held on product complexity by product designers.

AbstractComplex research problems are increasingly addressed by interdisciplinary, collaborate research projects generating large amounts of heterogeneous amounts of data. The overarching processing, analysis and availability of data are critical success factors for these research efforts. Data repositories enable long term availability of such data for the scientific community. The findability and therefore reusability strongly builds on comprehensive annotations of datasets stored in repositories. Often generic metadata schema are used to annotate data. In this publication we describe the implementation of discipline specific metadata into a data repository to provide more contextual information about data. To avoid extra workload for researchers to provide such metadata a workflow with standardised data templates for automated metadata extraction during the ingest process has been developed. The enriched metadata are in the following used in the development of two repository plugins for data comparison and data visualisation. The added values of discipline-specific annotations and derived search features to support matching and reusable data is then demonstrated by use cases of two Collaborative Research Centres (CRC 1368 and CRC 1153).
ENVIRONMENT-BASED DESIGN (EBD): USING ONLY NECESSARY KNOWLEDGE FOR DESIGNER CREATIVITY
Authors: Yang Jiami , Dou Yi , Zeng Yong 
Published: June 2023

AbstractDesign is a highly nonlinear chaotic dynamic process with many possible solutions, which requires enormous knowledge for designers. This paper investigates how environment-based design (EBD) methodology can help designers use only necessary knowledge for their creativity based on three methods: information search, knowledge acquisition and knowledge application. The methods are applied in an aircraft pylon design, which is evaluated by two aerospace design specialists. The paper discussed the different roles of EBD for novice and expert designers in regard to overcoming emotion and knowledge barriers to achieving designer creativity.
EVOLUTIONARY PERSPECTIVE ON SYSTEM GENERATION ENGINEERING BY THE EXAMPLE OF THE IPHONE
Authors: Pfaff Felix , Götz Gregor Theodor , Rapp Simon , Albers Albert 
Published: June 2023

AbstractIndustrial practice shows that products are developed in generations. Innovation success with complex technical systems can only be achieved economically by using existing solutions as references. These references come from predecessors, competitors, and even industry-external sources. The model of SGE – System Generation Engineering describes these relationships. The iPhone is often used as an example of an innovative product developed in generations. Multiple studies have examined the iPhone. However, none of these studies systematically considers the influence of the product context on references and variations. In this contribution, an evolutionary descriptive model based on the model of SGE is applied to 15 iPhone product generations. The central result is an overview of the variation shares over the generations and the relationships between context factors, reference-based variation activities, and innovation success and hypotheses for causalities. This is one of a series of case studies to investigate these causalities. The study showed how the iPhone remained successful in its context: not through a high new development share, but through strategically placed variations and the use of references from various sources.
EXPLICIT ANNOTATED 3D-CNN DEEP LEARNING OF GEOMETRIC PRIMITIVES INSTANCES

Published: June 2023

AbstractIn reengineering technical components, the robust automation of reverse engineering (RE) could overcome the need for human supervision in the surface reconstruction process. Therefore, an enhanced computer-based geometric reasoning to derive tolerable surface deviations for reconstructing optimal surface models would promote a deeper geometric understanding of RE downstream processes. This approach integrates advanced surface information into a deep learning-based recognition framework by explicitly labeling geometric outliers and subsurface boundaries. For this purpose, a synthetic dataset is created that morphs nominal surface models to resemble the macroscopic surface pattern of physical components. For the detection of regular geometry primitives, a 3D-CNN is used to analyze the voxelized components based on signed distance field data. This explicit labeling approach enables surface fitting to derive suitable shape features that fulfill the underlying surface constraints.
EXPLORING HEALTH AND DESIGN EVIDENCE PRACTICES IN EHEALTH SYSTEMS’ DEVELOPMENT
Authors: Morales Ornelas Hosana Cristina , Kleinsmann Maaike , Kortuem Gerd 
Published: June 2023

AbstractEvidence-based practices play an essential role in the development of eHealth systems. Prior research has investigated the challenge of shared understanding between professionals from the fields of health sciences and design and has highlighted the need for effective alignment of development and research practices in eHealth. However, there is a limited understanding of epistemological differences between these fields and how professionals conceptualise evidence. In this paper, we investigate how healthcare and design professionals think about evidence and how they implement evidence practices in their work. We interviewed eight professionals and used reflexive thematic analysis to identify the challenges and strategies associated with their evidence practices. Our results identify five shared evidence practices between healthcare and design professionals: stakeholder-driven, process-driven, problem-driven, effect-driven, and solution-driven. These five evidence practices indicate opportunities for closer alignment of development and research practices among healthcare and design professionals and offer a basis to create a shared understanding of evidence between both fields.
