APPLICATION OF DOMAIN INTEGRATED DESIGN METHODOLOGY FOR BIO-INSPIRED DESIGN- A CASE STUDY OF SUTURE PIN DESIGN
Authors: Velivela Pavan Tejaswi , Letov Nikita , Liu Yuan , Zhao Yaoyao Fiona 
Published: August 2021

AbstractThis paper investigates the design and development of bio-inspired suture pins that would reduce the insertion force and thereby reducing the pain in the patients. Inspired by kingfisher's beak and porcupine quills, the conceptual design of the suture pin is developed by using a unique ideation methodology that is proposed in this research. The methodology is named as Domain Integrated Design, which involves in classifying bio-inspired structures into various domains. There is little work done on such bio-inspired multifunctional aspect. In this research we have categorized the vast biological functionalities into domains namely, cellular structures, shapes, cross-sections, and surfaces. Multi-functional bio-inspired structures are designed by combining different domains. In this research, the hypothesis is verified by simulating the total deformation of tissue and the needle at the moment of puncture. The results show that the bio-inspired suture pin has a low deformation on the tissue at higher velocities at the puncture point and low deformation in its own structure when an axial force (reaction force) is applied to its tip. This makes the design stiff and thus require less force of insertion.

REVIEW OF DESIGN HEURISTICS AND DESIGN PRINCIPLES IN DESIGN FOR ADDITIVE MANUFACTURING
Authors: Valjak Filip , Lindwall Angelica 
Published: August 2021

AbstractThe advent of additive manufacturing (AM) in recent years have had a significant impact on the design process. Because of new manufacturing technology, a new area of research emerged – Design for Additive Manufacturing (DfAM) with newly developed design support methods and tools. This paper looks into the current status of the field regarding the conceptual design of AM products, with the focus on how literature sources treat design heuristics and design principles in the context of DfAM. To answer the research question, a systematic literature review was conducted. The results are analysed, compared and discussed on three main points: the definition of the design heuristics and the design principles, level of support they provide, as well as where and how they are used inside the design process. The paper highlights the similarities and differences between design heuristics and design principles in the context of DfAM.
SUPPORT-FREE METAL ADDITIVE MANUFACTURING: A STRUCTURED REVIEW ON THE STATE OF THE ART IN ACADEMIA AND INDUSTRY
Authors: Weber Sebastian , Montero Joaquin , Bleckmann Matthias , Paetzold Kristin 
Published: August 2021

AbstractEspecially in the Laser Powder Bed Fusion (L-PBF) technology for metals, current manufacturing systems require the use of support structure to withstand recoater forces and lower thermal induced stresses. These support structures set limitations on the design freedom and affect the surface quality, part cost and lead-time in an undesirable manner. Complex parts, which were not possible with conventional manufacturing methods, can be produced without these limitations. While some companies claim to print parts with horizontal overhangs without the use of support structure, academic research seems to deal with these limitations by defining design guidelines rather than eliminating them. In order to highlight the discrepancies between academia and industry, a structured review is presented. As result, severe differences in knowledge were discovered, which might emerge from the use of unconstrained cutting-edge systems in industry. Eventually support-free L-PBF is not yet fully developed, but the use of support structure can be drastically reduced by optimizing the build process.
SURFACE ROUGHNESS CONSIDERATIONS IN DESIGN FOR ADDITIVE MANUFACTURING - A LITERATURE REVIEW
Authors: Obilanade Didunoluwa , Dordlofva Christo , Törlind Peter 
Published: August 2021

AbstractOne often-cited benefit of using metal additive manufacturing (AM) is the possibility to design and produce complex geometries that suit the required function and performance of end-use parts. In this context, laser powder bed fusion (LPBF) is one suitable AM process. Due to accessibility issues and cost-reduction potentials, such ‘complex’ LPBF parts should utilise net-shape manufacturing with minimal use of post-process machining. The inherent surface roughness of LPBF could, however, impede part performance, especially from a structural perspective and in particular regarding fatigue. Engineers must therefore understand the influence of surface roughness on part performance and how to consider it during design. This paper presents a systematic literature review of research related to LPBF surface roughness. In general, research focuses on the relationship between surface roughness and LPBF build parameters, material properties, or post-processing. Research on design support on how to consider surface roughness during design for AM is however scarce. Future research on such supports is therefore important given the effects of surface roughness highlighted in other research fields.
SYSTEMATIC ANALYSIS OF CHANGING VEHICLE EXTERIOR DIMENSIONS AND RELEVANT VEHICLE PROPORTIONS
Authors: Holder Daniel 
Published: August 2021

AbstractFor the user perception of vehicles and consequently the success of automobile design, the body layout and especially the proportions of vehicles are pivotal. In the present study, the SAE main dimensions length (L108), wheelbase (L101), height (H100) and width (W103) of 697 vehicles from different OEMs were examined. The analysis reveals a tendency of increasing length, wheelbase and especially width of vehicles in recent years. Regarding the ratios of these dimensions there are clear correlations, as revealed by an analysis with linear regression. We find particular strong synchrony in the increases of the pairs W103 - L108 and L101 - L108 and lesser so between the ratio E = L108/L101 and the vehicle length. The latter can be explained by vehicles with a high L108 being less compact, i.e. the proportion E increases. Finally, it is discussed whether technological changes lead to revolutionary or evolutionary changes in dimensions. The historical development and the moderate proportional changes of BEVs indicate a measurable but evolutionary development. In contrast, disruptive technologies such as automated driving can significantly change the vehicle layout and thus encourage a more revolutionary change in proportions.

Published: August 2021

AbstractThe healthcare sector is facing significant challenges that require a systems approach, resulting in a rapid growth in the application of systems approaches in healthcare since the beginning of the 21st century. Consequently, healthcare practitioners and policymakers now desire to understand the evidence-base for the approach, but little evidence of the kind desired exists. This paper is a first step in conducting a narrative review of the application of systems approaches in healthcare based on a systematic review of the academic and grey literature. First, the emergence of the approach in healthcare is explored. Second, specific examples of applications of systems approaches in healthcare are examined to identify any missing elements in current practice. Third, fourteen reviews of the approach in healthcare published in the last ten years are analysed. The results suggest that the use of the approach in healthcare will most likely continue to increase, however, significant work remains for the design and systems community to demonstrate the effectiveness of systems approaches, specifically in providing convincing measures of impact on patient and service outcomes.

AbstractToday we live a high increasing digitalization in industry 4.0. As part of the evolution of CAD solutions on the market, there is a particular interest in new generation software which are distributed as Software-as-a- Service (SaaS) such as Onshape, 3D Experience, Fusion 360, etc. In order to prepare engineering students for integrating such software within the Université de Technologie de Compiègne (UTC), a further practicing study is carried out in this paper. This study aims to identify, analyze, experiment, evaluate and compare the capacities of Cloud-based CAD solutions on the market and in scientific research work in order to define potential benefits for their implementation in mechanical engineering education. Therefore, we tested two use scenarios of the two Cloud-based software; Onshape and Fusion 360 on a case study. Then, we discussed the comparison results.

Authors: Milovanovic Julie , Hu Mo , Shealy Tripp , Gero John 
Published: August 2021

AbstractThe research presented in this paper explores features of temporal design neurocognition by comparing regions of activation in the brain during concept generation. A total of 27 engineering graduate students used brainstorming, morphological analysis, and TRIZ to generate concepts to design problems. Students' brain activation in their prefrontal cortex (PFC) was measured using functional near-infrared spectroscopy (fNIRS). Temporal activations were compared between techniques. When using brainstorming and morphological analysis, highly activated regions are consistently situated in the medial and right part of the PFC over time. For both techniques, the temporal neuro-physiological patterns are similar. Cognitive functions associated to the medial and right part of the PFC suggest an association with divergent thinking and adaptative decision making. In contrast, highly activated regions over time when using TRIZ appear in the medial or the left part of the prefrontal cortex, usually associated with goal directed planning.
TEN TRANSFORM EMERGENCY NOW! - FACING COVID 19 WITH OPEN AND FRUGAL INNOVATION

Published: August 2021

AbstractAgainst a pandemic, speed is crucial, and open innovation (OI) helps to empower the human capital distributed around the world to tackle the disease and to launch rapid testing of possible solutions. This article aims at showing an OI program - called “TEN” Transform Emergency Now! - ideated and developed by the University of Bologna to identify, design, and implement useful solutions to tackle specific issues coming from pandemics. With an action research-innovation management approach, the University developed two iterations to identify what elements to take into account to define a program that works for this effort. In TEN, Frugal Innovation (FI) principles were injected in a 10 days hackathon to favor the use of locally available resources and raw materials and exclude non-essential features. Results show that Frugality can become an element of OI by (1) pushing the team towards basic functionality and minimal features of the solutions and low-cost implementation. (2) Designing, in parallel with the solution, an ‘implementation network’, with a specific process design and program's organizational perspective. We believe that TEN has the potential to be an OI approach designed for emergencies.

Published: August 2021

AbstractThe vehicle exterior design conveys a variety of visual information. Among these are the brand identity, assumed characteristics, and the vehicle's age or newness. While previous research focusses mainly on the first two attributes, we broaden the perspective by examining the age perception for vehicle model portfolios across brands.Information of age is embedded not only in branding but also in the entirety of a vehicle's exterior design features. Therefore, this paper examines how participants of a self-reported study perceive individual models inside successive product portfolios without typical branding. The stimulus patterns were derived from 12 different series of BMW, Mercedes-Benz and Audi and edited accordingly. A total of 67 models from the years 1968 to 2019 were presented and evaluated in terms of perceived age, model and brand recognition.The results show that most vehicles are perceived as newer than their actual age, successive model generations are clearly distinguishable and participants were able to sort all models in their correct chronological order. Finally, design-related age perception and knowledge-based age perception are introduced as possible underlying concepts of the visual perception of product age.
THE DARK SIDE OF METHODS – AN EXPLORATION OF THE NEGATIVE EFFECTS OF METHOD USE AND METHOD REFLECTION IN DESIGN
Authors: Hjartarson Björgvin , Daalhuizen Jaap , Gustafsson Karoline Fogh 
Published: August 2021

AbstractThe proper use of methods is increasingly important as design challenges are more complex and involve more stakeholders. Such work also demands high reflective ability from designers. Reflective thought processes do not necessary produce positive outcomes for the process and the individual involved. Positive reflection is goal oriented while negative reflection is typically self-oriented. In design education, reflection by students is often treated as rather trivial or only rudimentary support is offered. Research in cognitive science shows that poor reflection can hurt students' well-being, abilities and confidence over time. Thus, there is a need to better understand method use and reflection in design education more specifically when done poorly. We take a theory-building approach and interviewed 12 design students and recent graduates and investigated instances of method use where these led to negative experiences and effects. In doing so, we show different types of negative experiences that students have when using methods, the effects that these experiences have and how they relate to problematic use of methods and poor reflection practices. We end with implications for design education and design research.
TOWARDS A RESILIENCE ASSURANCE MODEL FOR ROBOTIC AUTONOMOUS SYSTEMS

Published: August 2021

AbstractApplications of autonomous systems are becoming increasingly common across the field of engineered systems from cars, drones, manufacturing systems and medical devices, addressing prevailing societal changes, and, increasingly, consumer demand. Autonomous systems are expected to self-manage and self-certify against risks affecting the mission, safety and asset integrity. While significant progress has been achieved in relation to the modelling of safety and safety assurance of autonomous systems, no similar approach is available for resilience that integrates coherently across the cyber and physical parts. This paper presents a comprehensive discussion of resilience in the context of robotic autonomous systems, covering both resilience by design and resilience by reaction, and proposes a conceptual model of a system of learning for resilience assurance in a continuous product development framework. The resilience assurance model is proposed as a composable digital artefact, underpinned by a rigorous model-based resilience analysis at the system design stage, and dynamically monitored and continuously updated at run time in the system operation stage, with machine learning based knowledge extraction and validation.
TRACING THE EMERGENCE OF DESIGN PROBLEMS AND THEIR IMPACTS ON THE COMPLEXITY OF ENGINEERING SOLUTIONS

Published: August 2021

AbstractThe design of ITER, a large-scale nuclear fusion reactor, is intertwined with profound research and development efforts. Tough problems call for novel solutions, but the low maturity of those solutions can lead to unexpected problems. If designers keep solving such emergent problems in iterative design cycles, the complexity of the resulting design is bound to increase. Instead, we want to show designers the sources of emergent design problems, so they may be dealt with more effectively. We propose to model the interplay between multiple problems and solutions in a problem network. Each problem and solution is then connected to a dynamically changing engineering model, a graph of physical components. By analysing the problem network and the engineering model, we can (1) derive which problem has emerged from which solution and (2) compute the contribution of each design effort to the complexity of the evolving engineering model. The method is demonstrated for a sequence of problems and solutions that characterized the early design stage of an optical subsystem of ITER.
TRANSFORMING DATA INTO ADDED-VALUE INFORMATION: THE DESIGN OF SCIENTIFIC MEASUREMENT MODELS THROUGH THE LENS OF DESIGN THEORY
Authors: Barbier Raphaëlle , Le Masson Pascal , Weil Benoit 
Published: August 2021

AbstractTransforming data into added-value information is a recurrent issue in the context of “big data” phenomenon, as new sources of data become increasingly available. This paper proposes to offer a fresh look on how data and added-value information are linked through the design of specific models. This investigation is based on design theory, used as an analysis framework, and on a historical example in the Earth science field. It aims at unveiling the reasoning logic behind the design process of models combining data science and domain knowledge in specific ways, especially involving not only knowledge about the physical phenomena but also on the measuring instrument itself. More specifically, this paper shows how specific efforts on exploring the originality of the new instrument compared to existing ones can result in designing performant models to transform new sources of data into information. This also suggests several important competencies to be involved in the model-design process: (1) a detailed understanding of the limitations of existing models (2) the ability to explore both the originality of the new source of data compared to existing ones (3) the ability of leveraging independent data sources.
TRANSPARENCY OF DESIGN AUTOMATION SYSTEMS USING VISUAL PROGRAMMING – WITHIN THE MECHANICAL MANUFACTURING INDUSTRY
Authors: Heikkinen Tim 
Published: August 2021

AbstractOne challenge with design automation is system transparency with adjustable granularity because of the many different forms of representation from multiple disciplines. Previous research has focused on visualization through the generation of graphs, packaging into electronic books, and model highlighting. The research presented in this paper focuses instead on a visual programming approach, commonly applied in the building industry, where design assets and external references are wrapped into visual components and managed on a canvas with information input/output relations displayed. This entails additional documentation efforts, but the visualization is arguably more useful as groups and levels of granularity are adjusted by the engineers themselves as a part of the development work. To explore visual programming and its potential benefits as a way of enabling transparency with adjustable granularity of DA systems within mechanical manufacturing industry, an existing textual design automation system was transformed into a visual one using Grasshopper® (a visual programming environment) and discussed with respect to DA system transparency, feature-based CAD, and DA system development.

Published: August 2021

AbstractThis paper analyses the use of information and communication technologies (ICTs) in a distributed product design project-based learning (PBL). The paper presents the ICT use of five international student teams during three product design phases: identification of opportunities, conceptual design, embodiment design. General results show that student teams used around 30 different ICTs for both taskwork and teamwork. Students reported that they used previously known ICTs or ICTs properly introduced to them during the initial course workshop. Results also show that team members often work individually on their tasks and use various procedures to share their results. Also, teams conduct some activities synchronously, suggesting the need for teams to have a collaborative workspace. Cloud-based collaborative ICTs (e.g. whiteboard, computer-aided design, document editor, task management) showed huge potential for individual and team tasks. Hence, educators and teams should carefully consider which ICTs to implement and learn, as it might greatly impact the execution of the product design PBL course.

Published: August 2021

AbstractModel-Based Systems Engineering (MBSE) is an efficient approach to support product development in order to meet today's challenges. The MBSE approach includes methods and, above all, modelling approaches of the technical system with the aim of continuous use in development. The objective of this paper is to use the potential of the MBSE models and to show the added value of such models on the system level when used as a single source. With this objective, this paper presents a three-step approach to systematically identify and apply meaningful modelling approaches within MBSE, based on the needs during the development process. Furthermore, an FMEA example is included in this paper to elaborate the use of MBSE in the system failure analysis.

AbstractHow to enhance creativity, especially by applying new technologies to creativity methods, is a question posed continuously by researchers. One reason for this is that creativity is an important part of people's daily lives and an essential component of society. Therefore, many methods to enhance creativity have been created, especially brainstorming, which is one of the most popular and effective tools that inspire individuals to generate ideas, hence enhancing creativity. Moreover, technologies, such as virtual reality (VR), provide an opportunity for individuals and groups to be creative. In response, recent studies have adopted VR in brainstorming to enhance creativity. However, there is a lack of systematic analysis of experimental approaches and creativity measures employed in this context. Addressing this question, this study categorized existing articles on the topic related to categories of avatars, environments, interfaces, or applications. The findings elaborate on trends, measures employed to evaluate creativity and idea generation, identified categories, and results of these studies.
