Une tradition d’innovation: Les Annales dans le paysage transnational des revues d’histoire, 1990-2020

Cet essai examine les Annales au prisme de revues d’histoire comparables et, parfois, concurrentes. En se concentrant sur leurs choix éditoriaux, notamment sur les titres de leurs numéros spéciaux et thématiques, il met en évidence la circulation transversale et transnationale des approches et des sujets de recherche. Une dizaine de revues provenant de différents pays sont analysées sur les trente dernières années ; elles partagent avec les Annales une même pratique, celle d’afficher leurs ambitions conceptuelles et leurs choix thématiques par le biais de mots-clefs et de titres. Considérées ensemble, ces revues d’histoire construisent un vaste texte où se trame l’agenda de l’historiographie internationale. De nouveaux thèmes de recherche comme la micro-histoire, l’histoire du quotidien, les identités religieuses et ethniques, les relations genrées et les inégalités sociales ou encore l’histoire globale et le changement climatique sont ainsi mis en circulation dans le dialogue et la compétition. Au sein de ce paysage dynamique, les Annales ont poursuivi et maintenu leur tradition d’innovation.

Published: August 2021

The COVID-19 pandemic has demonstrated that emergency departments (EDs) need to reorganize their operations rapidly. This study investigated the impact of the pandemic on structural and logistical issues at EDs and the measures taken. Belgian EDs were surveyed on the implemented changes at the start of the pandemic in relation to the 4 S’s in disaster medicine: Structure, Staff, Supplies, and System. The study demonstrated that Belgian EDs felt largely unprepared for this pandemic, but nevertheless dynamically restructured their organization. A 46% increase in ED beds was created in different types of structures and more than 50% of all ED beds were reserved for COVID-19 care, but overall the number of patient presentations dropped by 29%. EDs deployed extra personnel, additional training, and psychological support. More than 50% reported an acute shortage of personal protective equipment, and several reported a shortage of ventilatory equipment and medications.

Authors: Duong Minh Cuong , Nguyen Hong Trang , Duong Bich Thuy , Vu Minh Thuy
Published: August 2021

Objective:

Effective handwashing practices help prevent the spread of coronavirus disease 2019 (COVID-19). This study examined the knowledge, frequency, and characteristics of handwashing practices among Vietnamese university students.

Methods:

An analytic cross-sectional study was conducted on all students enrolling at Phenikaa University in Vietnam. A self-developed questionnaire was used to collect information on the participants’ knowledge regarding the effectiveness of handwashing as a COVID-19 preventive measure, the moments for hand hygiene, the most appropriate practices in different situations, and frequency.

Results:

Among 728 study participants, 460 (63.2%) were from health-related faculties. Almost (97.9%; 713/728) all participants knew that handwashing could protect against the spread of infection, but less than half performed handwashing often in a normal day (47.4%; 345/728), after sneezing or coughing (48.9%; 356/728), and 7.4% (54/728) only washed hands when hands are visibly dirty. Health students used alcohol-based handrub in all situations, including those requiring handwashing with water and soap (P < 0.05).

Conclusions:

The levels of knowledge regarding the effectiveness of handwashing among study participants are high, but actual practices of handwashing are suboptimal. It is crucial to improve community education to help reinforce correct hand hygiene behaviors, including when to wash hands and which method should be used.
DESIGNING A DATA VISUALISATION AND ANALYSIS TOOL FOR SUPPORTING DECISION-MAKING WITH PUBLIC TRANSPORTATION NETWORK
Authors: Vallet Flore , Khouadjia Mostepha , Amrani Ahmed , Pouzet Juliette
Published: August 2021

Massive data are surrounding us in our daily lives. Urban mobility generates a very high number of complex data reflecting the mobility of people, vehicles and objects. Transport operators are primary users who strive to discover the meaning of phenomena behind traffic data, aiming at regulation and transport planning. This paper tackles the question "How to design a supportive tool for visual exploration of digital mobility data to help a transport analyst in decision making?” The objective is to support an analyst to conduct an ex post analysis of train circulation and passenger flows, notably in disrupted situations. We propose a problem-solution process combined with data visualisation. It relies on the observation of operational agents, creativity sessions and the development of user scenarios. The process is illustrated for a case study on one of the commuter line of the Paris metropolitan area. Results encompass three different layers and multiple interlinked views to explore spatial patterns, spatio-temporal clusters and passenger flows. We join several transport network indicators whether are measured, forecasted, or estimated. A user scenario is developed to investigate disrupted situations in public transport.
A FUZZY FRONT-END PRODUCT DEVELOPMENT FRAMEWORK FOR START-UPS
Authors: Martins Pacheco Nuno Miguel , Vazhapilli Sureshbabu Anand , Nürnberger Masaru Charles , Durán Noy Laura Isabel , Zimmermann Markus
Published: August 2021

Start-ups tend to form with a central idea that differentiates them from their competitors in the market. It is crucial for them to efficiently transform the idea into a marketable product. Prototyping helps to iteratively achieve a minimum viable product and plays a crucial role by enabling teams to test their ideas with limited resources early on. However, the prototyping process may have wrong focus leading to a suboptimal allocation of resources. Previously, we proposed role-based prototyping for fuzzy front-end development in small teams. It supports (1) resource allocation, (2) the definition of responsibilities, and (3) structuring the development process with milestones. In recent research this was a promising yet incomplete approach. We extend the previous work by refining the prototyping process by adding a prototyping matrix with two dimensions (purpose and lens), a prototyping cycle (plan, execute, test, reflect, assimilate), and a modified Kanban board (Protoban) for planning, managing, and reflecting cycles. This process, named PETRA was tested with a start-up developing an autonomous trash picking robot. The extended approach supported the team significantly in providing a clear idea of what to do at what time.
DIFFERENCES BETWEEN BEGINNING AND ADVANCED STUDENTS USING SPECIFIC ANALOGICAL STIMULI DURING DESIGN-BY-ANALOGY
Authors: Xu Jiang , Lu Han , Jiang Yu
Published: August 2021

Studies reported the effects of different types and different levels of abstraction of analogical stimuli on designers. However, specific, single visual analogical stimuli on the effects of designers have not been reported. We define this type of stimuli as specific analogical stimuli. We used the extended linkography method to analyze the facilitating and limiting effects of specific analogical stimuli and free association analogical stimuli (nonspecific analogical stimuli) on the students' creativity at different design levels. The results showed that: (1) Advanced students focused on exploring the depth of the design problem while beginning students tended to explore the breadth of the design problem. (2) Nonspecific analogical stimuli enhanced the creativity of beginning students. However, its impact on advanced students is less pronounced. (3) The specific analogical stimuli attract the students into design fixation. Furthermore, it has a more pronounced effect on advanced students. These results illustrate the differences in the effects of specific analogy stimuli on the students at different design levels. It clarifies the use of analogical stimuli in design and the teaching of analogical design methods in design education.
DIGITAL TRANSFORMATION TYPES FOR PRODUCT-SERVICE SYSTEMS
Authors: Kim Yong Se
Published: August 2021

Digital transformation has become a mega trend topic for many enterprises globally. For some companies, customer interactions have been digitalized. But many companies still rely on physical interactions of customers with their products in the core value creation processes. Thus the key challenges for digital transformation efforts would be associating product-centered value propositions with digitalized services. In other words, the transformation of product-centered values into experience values co-created by customers with services supporting customers. The research goal of this paper is to identify different strategies for digital transformation in product-service systems (PSS) design so that diverse paths for digital transformation can be considered in designing PSSs. Three types for digital transformation strategies have been identified from PSS design cases conducted in a manufacturing servitization support framework project where PSSs have been designed for 15 manufacturing companies including SMEs and large companies with varying levels of digital technology. A classification for digital transformation strategies could be postulated with three primary dimensions and two supplementary dimensions.
DYSLEXIA AND SELF-DEVELOPMENT; A PRODUCT FOR PRIMARY SCHOOL CLASSROOMS TO ENCOURAGE SOCIAL INTERACTION WITH THE INTENT OF IMPROVING SELF-ESTEEM.
Authors: Laschok Zac Michael , Lim Younghun
Published: August 2021

With an ever-increasing body of primary school children and the degradation of mental health among young people, the development of a high self-esteem at a primary school level has been recognised as a huge driving force towards the wellbeing of the next generation. Although the poor mental health of young people in their teenage years is widely talked about and addressed, it is often missed that this stems from a much younger age. The people most likely to suffer with a lower self-esteem at a young age are those with a learning differences, weather mild, diagnosed or undiagnosed. This paper will explore how emerging cognitive differences, and positive social interaction can help steer a child’s self-development away from problems later in life such as anxiety and depression. Using these findings, a physical classroom-based game was conceived, designed and tested on the end users in the classroom environment.
EMBRACING NEW VISUALISATION TOOLS IN EDUCATION: HOW THE LEARNING EXPERIENCE OF DIGITAL SKETCHING INFLUENCES ITS USE IN DESIGN PRACTICE
Authors: Zhang Wenwen , Ranscombe Charlie
Published: August 2021

Numerous visualisation tools based on digital and cross-reality (XR) platforms are emerging in industrial design. They offer new possibilities and promising advantages to the designers but also raise challenges for design education. This study investigates the learning experience of emerging tools in education and its influences on tool-use behaviours and attitudes in design practice. Digital sketching is selected for the case study as the emerging tool compared to more established tools (e.g., traditional sketching and CAD). Semi-structured interviews were conducted with 12 practising designers to compare their learning experience of digital sketching versus traditional sketching and CAD modelling in formal education. Results indicate that designers’ learning experience in education can have an influence on not only their skill sets but also attitudes towards engaging with emerging visualisation tools as they progress in their careers. The study suggests that embracing emerging design visualisation tools in education now is essential for helping our future designers be more resilient and flexible with tool selection and use in their future design practice.
A MODELLING FRAMEWORK FOR DATA-DRIVEN DESIGN FOR SUSTAINABLE BEHAVIOUR IN HUMAN-MACHINE INTERACTIONS
Authors: Montecchi Tiziano , Becattini Niccolo'
Published: August 2021

As the society is already permeated by data, a data-driven approach to inform design for sustainable behaviour can help to identify misbehaviours and target sustainable behaviours to achieve, as well as to select and implement the most suitable design strategies to promote a behavioural change and monitor their effectiveness. This work addresses the open challenge of providing designers with a model for Human-Machine Interactions (HMI) that helps to identify relevant data to collect for inferring user behaviour related to environmental sustainability during product use.

We propose a systematic modelling framework that combines constructs from existing representation techniques to identify the most critical variables for resources consumption, which are the determinants of potential misbehaviours related to HMI. The analysis is represented as a Behaviour-Inefficiency Model that graphically supports the analyst/designer to link user behaviours with a quantitative representation of resources consumption.

The paper describes the model through an example of the use of a kettle and an additional application of the same approach to a washing machine, in order to point out its versatility for modelling more complex interactions.
A RELIABILITY INSPIRED STRATEGY FOR INTELLIGENT PERFORMANCE MANAGEMENT WITH PREDICTIVE DRIVER BEHAVIOUR: A CASE STUDY FOR A DIESEL PARTICULATE FILTER
Authors: Doikin Aleksandr , Campean Felician , Priest Martin , Lin Chunxing , Angiolini Emanuele
Published: August 2021

The increase availability of operational data from the fleets of cars in the field offers opportunities to deploy machine learning to identify patterns of driver behaviour. This provides contextual intelligence insight that can be used to design strategies for online optimisation of the vehicle performance, including compliance with stringent legislation. This paper illustrates this approach with a case study for a Diesel Particulate Filter, where machine learning deployed to real world automotive data is used in conjunction with a reliability inspired performance modelling paradigm to design a strategy to enhance operational performance based on predictive driver behaviour. The model-in-the-loop simulation of the proposed strategy on a fleet of vehicles showed significant improvement compared to the base strategy, demonstrating the value of the approach.
A STUDY INTO DESIGNING AN AMBIENT WATER BOTTLE THAT SUPPORTS USERS' WATER-INTAKE TRACKING PRACTICES
Authors: Coskun Aykut , Yildiz Mert , Yilmazer Hakan , Genç Hüseyin Uğur
Published: August 2021

Taking on the challenge of motivating users to drink water regularly, we designed a smart water bottle that can track water intake behavior and inform users about this behavior through ambient feedback. We then conducted two studies to explore the bottle's feedback design from the perspective of users and designers. First, we conducted semi-structured interviews with 10 prospective users and found that they would like to receive personalized, precise, gamified and reminding feedback. Second, we conducted a design workshop with 13 professional designers to explore the range of visualizations that can be used to give feedback. Analyzing these visualizations, we identified three reminder types (augmenting, restoring and balancing) and six visualization styles grouped according to three dimensions of ambient displays (representation fidelity, notification level, aesthetic emphasis). In this paper, we first explain our water bottle concept along with existing solutions. Then, we report the results of these studies. Finally, we discuss the potential implications of the results for our own work as well as for designing ambient displays aimed at supporting users' water intake tracking practices.

Published: August 2021

Integrated Natural Resource Conservation and Development (INRCD) Projects are efforts at worldwide locations to promote economic development of local communities consistent with conservation of natural resources. This umbrella term includes Integration Conservation and Development Projects (ICDPs) introduced by the World Wide Fund to combine social development and conservation s through the use of socio-economic investments, and the Integrated Natural Resource Management (INRM) research and development efforts that have employed a systems approach for quantitative modeling and optimization. In the spirit of the INRCD framework, we describe the development of a system-level agriculture and energy model comprising engineering and economic models for crop, irrigation, and energy subsystem designs for a community in Central Uganda. The model architecture is modular allowing modifications for different system configurations and project locations. We include some initial results and discuss next steps for system optimization, refining model assumptions, and modeling community social benefits as drivers of such projects.
A SYSTEMATIC COLLECTION OF NATURAL INTERACTIONS FOR IMMERSIVE MODELING FROM BUILDING BLOCKS
Authors: Harlan Jakob , Schleich Benjamin , Wartzack Sandro
Published: August 2021

The increased availability of affordable virtual reality hardware in the last years boosted research and development of such systems for many fields of application. While extended reality systems are well established for visualization of product data, immersive authoring tools that can create and modify that data are yet to see widespread productive use. Making use of building blocks, we see the possibility that such tools allow quick expression of spatial concepts, even for non-expert users. Optical hand-tracking technology allows the implementation of this immersive modeling using natural user interfaces. Here the users manipulated the virtual objects with their bare hands. In this work, we present a systematic collection of natural interactions suited for immersive building-block-based modeling systems. The interactions are conceptually described and categorized by the task they fulfil.
A USER-CENTRED DESIGN FRAMEWORK FOR THE DEVELOPMENT OF SPEECH AND LANGUAGE THERAPEUTIC TOYS
Authors: Balzan Emanuel , Farrugia Philip , Casha Owen
Published: August 2021

Therapy in early childhood is facilitated through toys and play. While mainstream toys are designed for children, therapeutic toys need to satisfy requirements from clinicians, caregivers, and children. The study presented in this paper investigated the challenges that 22 international toy designers encounter during the design process and whether support is required when developing products for speech and language therapy, through a mixed-method approach. Results show that considerable challenges are encountered during the early design stages. Nonetheless, the toy design process remains unsupported, while no support is available for designers to consider therapeutic needs. Based on the feedback received, eleven requirements were identified upon which a user-centred design support framework was proposed to assist toy designers during the task clarification stage, taking into account the affordances that therapeutic toys should have without inhibiting the creative process.
ADDITIVE MANUFACTURING – ENABLING DIGITAL ARTISANS
Authors: Rautray Priyabrata , Eisenbart Boris
Published: August 2021

New technologies have always been disruptive for established systems and processes. Additive Manufacturing (AM) is proving to be one such process which has the potential to disrupt handicraft and its manufacturing processes. AM is customisable, adopt multiple materials and is not restricted by the manufacturing process. Our research discusses this global phenomenon with case studies to highlights the growth of a new kind of professionals known as ‘Digital Artisans’. These artisans will assimilate the latest technologies with the cultural practices of the societies to create a new genre of products. The evolution of such artisans will be majorly led by people who have an equal inclination towards art and science and can act as the bridge between the handicrafts and technology. The development of such artisans will be supported by academics that will serve as a cradle and expose them to AM, design and handicraft. Its will also help in paving the growth of contemporary artisans who will utilise the strength of algorithms, artificial intelligence, CAD software and traditional aesthetics to create handicrafts of the future.
EXPLORING LOCAL RECIRCULATION OF PAPER WASTE THROUGH UPCYCLING AND ARTISTIC RECYCLING
Authors: Rohsig Lopez Nicole Sofia , Faucheu Jenny
Published: August 2021

Local recirculation of materials is a key aspect for a green transition, as it enables materials to be reused in new life cycles locally. In this article, we use the material “paper” as a case study to explore how this material recirculates at the local scales. This article aims at observing and evaluating upcycling scenarios as part of an expansion of local end-of-life possibilities compared to the current situation where paper end-of-life is reduced to a few recycling plants in France and abroad. This work relies on interviews and questionnaires that aim at understanding how paper is used and explored by artists to be recirculated in products. Indicators were tested to provide a methodology to compare different material circulation scenarios in terms of material use, environmental impact and value perception. Collaboration among multiple actors, artists, community centres, schools and industrial players is crucial for scaling up such recirculation loops.
EXPLORING SYSTEMIC FORCES THAT INFLUENCE SUSTAINABLE DESIGN TRANSITIONS
Authors: Watz Matilda , Hoffenson Steven , Hallstedt Sophie. I.
Published: August 2021

In 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

Design 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

Lightweight 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
Authors: Montero Joaquin , Weber Sebastian , Petroll Christoph , Brenner Stefan , Bleckmann Matthias , Paetzold Kristin , Nedeljkovic-Groha Vesna
Published: August 2021

Commercially 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

Innovation 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.
HOW COVID-19 ENABLED A GLOBAL STUDENT DESIGN TEAM TO ACHIEVE BREAKTHROUGH INNOVATION
Authors: Elfsberg Jenny Victoria , Johansson Christian , Frank Martin , Larsson Andreas , Larsson Tobias , Leifer Larry
Published: August 2021

This 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.
HUMAN AND PLANET CENTERED APPROACH: PROSPERITY THINKING IN ACTION
Authors: Vignoli Matteo , Roversi Sara , Jatwani Chhavi , Tiriduzzi Margherita
Published: August 2021

This 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
Authors: Steffan Kay-Eric , Fett Michel , Kurth Daniel , Kirchner Eckhard
Published: August 2021

Additive 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
Authors: Burleson Grace Ellen , Herrera Sean Vincent Salazar , Toyama Kentaro , Sienko Kathleen H.
Published: August 2021

Engineering 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

Integrated 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
Authors: Mbow Mouhamadou Mansour , Marin Philippe René , Perry Nicolas , Vignat Frédéric , Grandvallet Christelle
Published: August 2021

In 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

This 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

Design, 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

Contrary 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.

Published: August 2021

The 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.

In 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.

In 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

This 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.

The ever-increasing competitiveness, due to the market globalisation, has forced the industries to modify their design and production strategies. Hence, it is crucial to estimate and optimise costs as early as possible since any following changes will negatively impact the redesign effort and lead time.

This paper aims to compare different parametric cost estimation methods that can be used for analysing mechanical components. The current work presents a cost estimation methodology which uses non-historical data for the database population. The database is settled using should cost data obtained from analytical cost models implemented in a cost estimation software. Then, the paper compares different parametric cost modelling techniques (artificial neural networks, deep learning, random forest and linear regression) to define the best one for industrial components.

Such methods have been tested on 9 axial compressor discs, different in dimensions. Then, by considering other materials and batch sizes, it was possible to reach a training dataset of 90 records. From the analysis carried out in this work, it is possible to conclude that the machine learning techniques are a valid alternative to the traditional linear regression ones.
PART ORIENTATION AND SEPARATION TO REDUCE PROCESS COSTS IN ADDITIVE MANUFACTURING
Authors: Reichwein Jannik , Kirchner Eckhard
Published: August 2021

Additive manufacturing offers great potential in geometric design through the layer-by-layer production of components. This is often used in the development of additively manufactured components to make components lighter. An even greater reduction in mass is possible if several components are combined into a more complex component. However, as complexity increases, so do the manufacturing costs, due to a higher demand for supporting structure, reworking and longer production time. Especially for complex components, which make poor use of the space available in the additive manufacturing system, component separation can be a useful way of reducing manufacturing costs. Therefore, a procedure for automated component separation is presented, which determines an optimal cutting plane with respect to the manufacturing costs. The presented procedure is evaluated using two exemplary components where a reduction of manufacturing costs up to 54 % could be achieved.
