Published: August 2021

AbstractAeroengine manufacturers need to better include assessment of risk and cost for realising the novel products needed to meet the ambitions sustainability driven targets for air transport. Radical technologies are needed that simultaneously require critical manufacturing processes to be assessed already in conceptual design.In this paper, a multi-domain framework for conceptual design and evaluation is proposed that provide the ability to interactively explore the concepts that simultaneously allow a wider range of architectures can be assessed and still include weldability of the concepts.It has been demonstrated how high level, and function driven conceptual design alternatives can be modelled and evaluated to analyse risk and resilience of architectures. Geometrical concepts generated for the most interesting regimes using design of experiments covering a desired design space. For each CAD-model the welding process can be simulated to assess feasibility and lead time for welding, and return quantified results to be included in an integrated results data set for interactive decision making. The paper is the first report from a research project that improve concurrent design of product and production concepts.
NOVICE DESIGNERS' USE OF PARTITIONING STRATEGIES TO NAVIGATE THE PROTOTYPING PROCESS
Authors: Hansen Camilla Arndt , Deininger Michael 
Published: August 2021

AbstractPrototypes can be used to create value in all phases of the product development process. Prototyping strategies that determine how prototypes are developed should therefore be considered for the prototyping process as a whole. In this paper, we analyse how partitioning strategies were used by ten novice design teams to navigate their prototyping processes during a three-week mechatronic development project. Using the ‘ProtoMapping’ method, their prototyping strategies were visualized and five different types of strategies identified. Four of the ten teams formally planned how to divide their product into modules that could be prototyped in parallel or planned when to integrate prototypes to test the full product. Still, the ProtoMaps showed that most of the teams used some partitioning strategies during their project even when they did not formally decide to do so. Novice designers should be supported in making such strategies for the prototyping process deliberately. Therefore, prototyping tools should be expanded to support not only individual prototyping activities but also the prototyping process.

Published: August 2021

AbstractOver the last ten years, several stakeholders from the higher education sector have been involved in the area of student activation. This is due to the fact that, among other things, lecturers can get better feedback from the learners through active learning and thus can make the lecture more goal-oriented. Due to technological progress and currently available learning platforms, interactive methods are often used, which can be carried out with the help of online tools. Among the most commonly used methods are Peer Instruction (PI) and Just in Time Teaching (JiTT).All kinds of Mixed Reality are increasingly used in industrial and social context, such as product development processes. Through Augmented Reality (AR) technology and the constant availability of powerful mobile devices, 3D-based content can be virtually linked to the real environment. This enables teaching complex content efficiently, which is otherwise difficult to achieve using conventional methods.This paper shows an example on the creation of an AR-Experience to activate students even in a situation, that prevents attandence learning. The procedure is explained along the design and calculation of a non-switchable clutches within the lecture "machine elements".

Authors: Dharani Pragada Venkata Aditya , Banerjee Akanistha , Venkataraman Srinivasan 
Published: August 2021

AbstractAn efficient general arrangement is a cornerstone of a good ship design. A big part of the whole general arrangement process is finding an optimized compartment layout. This task is especially tricky since the multiple needs are often conflicting, and it becomes a serious challenge for the ship designers. To aid the ship designers, improved and reliable statistical and computation methods have come to the fore. Genetic algorithms are one of the most widely used methods. Islier's algorithm for the multi-facility layout problem and an improved genetic algorithm for the ship layout design problem are discussed. A new, hybrid genetic algorithm incorporating local search technique to further the improved genetic algorithm's practicality is proposed. Further comparisons are drawn between these algorithms based on a test case layout. Finally, the developed hybrid algorithm is implemented on a section of an actual ship, and the findings are presented.
OVERCOMING AUGMENTED REALITY ADOPTION BARRIERS IN DESIGN: A MIXED PROTOTYPING CONTENT AUTHORING TOOL SUPPORTED BY COMPUTER VISION
Authors: Piñones Eduardo , Cascini Gaetano , Caruso Giandomenico , Morosi Federico 
Published: August 2021

AbstractEnhancing the appearance of physical prototypes with digital elements, also known as mixed prototyping, has demonstrated to be a valuable approach in the product development process. However, the adoption is limited also due to the high time and competence required for authoring the digital contents. This paper presents a content authoring tool that aims to improve the user acceptance by reducing the specific competence required, which is needed for segmentation and UV mapping of the 3D model used to implement a mixed prototype. Part of the tasks related to 3D modelling software, in fact, has been transferred to simpler manual tasks applied onto the physical prototype. Moreover, the proposed tool can recognise these manual inputs thanks to a computer-vision algorithm and automatically manage the segmentation and UV mapping tasks, freeing time for the user in a task that otherwise would require complete engagement. To preliminarily evaluate effectiveness and potential of the tool, it has been used in a case study to build up the mixed prototype of a coffee machine. The result demonstrated that the tool can correctly segment the 3D model of a physical prototype in its relevant parts and generate their corresponding UV maps.
APPLICATION OF MUNICH AGILE CONCEPTS FOR MBSE AS A HOLISTIC AND SYSTEMATIC DESIGN OF URBAN AIR MOBILITY IN CASE OF DESIGN OF VERTIPORTS AND VERTISTOPS
Authors: Salehi Vahid , Wang Shirui 
Published: August 2021

AbstractThis paper will adopt the Munich Agile Concepts (MAGIC) on the design of Vertistops and Vertiports (Verti-X) for Urban Air Mobility (UAM) Systems. Vertiports and Vertistops are single or multi-landing spaces for air taxis, which are electric-powered vertical take-off and landing (eVTOLs) aircraft. The target of this paper is to apply a holistic approach how to design so called Verti-X in a holistic and system of system method from the Requirement-, Function-. Architecture- and the Implementation phase. The MAGIC approach contains all of the requierd phases which are necessary to build up such a complex design of Verti-X. Therefore, based on the literature survey, we have determined the key components of the Verti-X design with a thorough requirement analysis. Then, we have followed the existed criteria and regulations to design a valid and verified Verti-X which fulfills all the requirement. Furthermore, the focus of this paper is to apply the first four phases of MAGIC regarding the requirement, function, architecture and the implementation of such Verti-X Design.

Published: August 2021

AbstractEurope's healthcare systems are under strain with an ageing population contributing to increased risk of strokes. Rapid technology adaption is needed to prevent, rehabilitate and manage symptoms. This paper identifies what technology platforms are most familiar and accessible to stroke patients to guide designers and engineers to develop future interventions. A survey was distributed to 100 inpatients at a stroke unit, identifying patients' accessibility and usage of personal technologies. Results showed that desktop/laptops and smartphones were most used as opposed to tablets and smartwatches. Different technologies were used for different tasks with a notable lack of devices used for personal health. The underlying reasons for this are discussed with recommendations made on what personal technology platforms should be implemented by designers and engineers in technology-based health interventions.
POTENTIAL MODEL - METHODICAL EVALUATION OF INDUSTRY 4.0 TECHNOLOGIES
Authors: Schneider David , Huth Tobias , Vietor Thomas 
Published: August 2021

AbstractWith regard to the currently perceptible technological, social and economic change, also known as the “Fourth Industrial Revolution” or “Internet of Things”, small and medium-sized enterprises (SMEs) in particular are confronted with various obstacles in their attempt of keeping pace. For example, there is a lack of orientation of which I4.0 technology is suitable for a target-oriented application. Furthermore, the actual or potential effects of I4.0 can only be estimated insufficiently and SMEs are at a disadvantage compared to large companies due to lower monetary and personnel capacities. In this publication these obstacles on the way to become an I4.0 company are taken up and the core elements of a methodical solution approach in the form of the “Potential Model” are explained in detail. Thereby the Potential Model is intended to support SMES at the rough-quantitative evaluation of I4.0 and the development of I4.0 implementation strategies with minimal monetary and time-related efforts needed.

Published: August 2021

AbstractThis paper examines the immediate effects of group methods in facilitating remote team collaboration. We recruited seven teams with prior experience working together. All teams completed two current, complex, and open-ended design challenges using remote tools. We examined design activities before and after teams were given a design method intervention. The interventions were a Brainstorming Method to promote divergent thinking and the Five-Whys method to promote analytical thinking. Using OpenFace, we observed changes in emotion by examining facial expressions. We found that the brainstorming intervention did not have a change in ideation performance and the problem analysis intervention had a decrease in ideation performance. Teams used digital media to facilitate communication but were constrained by the media's tools. Our results can inform teams in organizations interested in promoting divergent thinking to not expect immediate improvements in ideation performance following the introduction of a design method. Future research is required to identify relevant abilities and social skills needed to facilitate remote ideation through design methods.
SELECTION OF REFERENCE SYSTEM ELEMENTS IN THE MODEL OF PGE - PRODUCT GENERATION ENGINEERING: METHOD FOR THE INTEGRATION OF CUSTOMER AND USER SATISFACTION IN PRODUCT PLANNING

Published: August 2021

AbstractIn the development of mechatronic systems, it is important to differentiate the products to be developed from those of the competitors, but also from the own product generations already available on the market. However, there are uncertainties regarding the correct features to be differentiated from the customer and user perspective and how these features should be designed. Nevertheless, despite the high impact, decisions must be taken early in the development process. Within this publication, a method to support in this respect was derived based on the findings of the Model of PGE - Product Generation Engineering and the Kano-Model. Therefore, experienceable product features and reference system elements as characteristics of these are evaluated according to the Kano-Model and thus made comparable with regard to the customers and user satisfaction. The objective is to select the product features to be differentiated and the corresponding reference system elements in such a way that a desired level of customer and user satisfaction is achieved. In order to evaluate the method, it was applied in a real development project. It was found that the application of the method led to a reduction of the existing uncertainty.

AbstractA comminution process is a material size reduction and separation process which is primarily used in the aggregates and the minerals processing industry. Knowledge related to equipment’s operation, raw material properties, operational strategies, control system, maintenance, etc. is needed to design a capable plant. New needs are arising from the industry for existing operational crushing plants such as investigation for improvements, upscaling, and downscaling of the capacity. The paper presents an application of simulation-driven development for a crushing plant in an existing gold processing plant. Due to the change in ore characteristics and the need for optimizing the cost of operation, it is required to investigate the opportunities for improvement and alternative options for downscaling the capacity of the plant. A systematic process for configuring, developing, and evaluating alternative concepts using a process simulation tool is presented. The results show the process of generating knowledge for alternative crushing plant operation settings and how the choices can be selected and eliminated using boundary conditions. The evaluation presents possible improvements and alternative concepts with their opportunities and pitfalls.
SIMULTANEOUS DEFINITION OF KEY CHARACTERISTICS IN ORDER TO FACILITATE ROBUST DESIGN IN EARLY PRODUCT DEVELOPMENT STAGES
Authors: Goetz Stefan , Horber Dennis , Schleich Benjamin , Wartzack Sandro 
Published: August 2021

AbstractThe success of complex product development projects strongly depends on the clear definition of target factors that allow a reliable statement about the fulfilment of the product requirements. In the context of tolerancing and robust design, Key Characteristics (KCs) have been established for this purpose and form the basis for all downstream activities. In order to integrate the activities related to the KC definition into product development as early as possible, the often vaguely formulated requirements must be translated into quantifiable KCs. However, this is primarily a manual process, so the results strongly depend on the experience of the design engineer.In order to overcome this problem, a novel computer-aided approach is presented, which automatically derives associated functions and KCs already during the definition of product requirements. The approach uses natural language processing and formalized design knowledge to extract and provide implicit information from the requirements. This leads to a clear definition of the requirements and KCs and thus creates a founded basis for robustness evaluation at the beginning of the concept design stage. The approach is exemplarily applied to a window lifter.

Published: August 2021

AbstractMaintenance decision making is an important part of managing the costs, effectiveness and risk of maintenance. One way to improve maintenance efficiency without affecting the risk picture is to group maintenance jobs. Literature includes many examples of algorithms for the grouping of maintenance activities. However, the data is not always available, and with increasing plant complexity comes increasingly complex decision requirements, making it difficult to leave the decision making up to algorithms.This paper suggests a framework for the standardisation of maintenance data as an aid for maintenance experts to make decisions on maintenance grouping. The standardisation improves the basis for decisions, giving an overview of true variance within the available data. The goal of the framework is to make it simpler to apply tacit knowledge and make right decisions.Applying the framework in a case study showed that groups can be identified and reconfigured and potential savings easily estimated when maintenance jobs are standardised. The case study enabled an estimated 7%-9% saved on the number of hours spent on the investigated jobs.
STUDY OF SYSTEM INTERFACES THROUGH THE NOTION OF COMPLEMENTARITY
Authors: Brovar Yana , Menshenin Yaroslav , Fortin Clement 
Published: August 2021

AbstractUnderstanding emergence is an important goal of system thinking, as it can express both desirable and negative properties of products and systems. Emergence has also a special importance as it has a direct link to the performance of products and systems, and thus has a direct relationship with the quality of life and thus sustainability in our societies. Emergence and system thinking are closely related to engineering design methodologies. In our paper, we develop a more precise definition of emergence through the core principles of systems complementarity that are similarity, irreducibility and sophisticated relationships expressed through the interfaces between systems, subsystems or product components.We demonstrate the utility of the approach based on an aircraft pylon case study by presenting a detailed definition of an interface design matrix and analyse how pylon subsystems influence emergence. The results have shown that the product can be perfectly represented by a model-based approach supporting interface management and the assessment of system complementarity. In turn, this approach allows to go beyond a qualitative definition of emergence, as it proposes a quantitative approach through the assessment of complementarity.
SUBDIVISION SURFACE MID-SURFACE RECONSTRUCTION OF TOPOLOGY OPTIMIZATION RESULTS AND THIN-WALLED SHAPES USING SURFACE SKELETONS
Authors: Denk Martin , Rother Klemens , Paetzold Kristin 
Published: August 2021

AbstractPolygon meshes and particularly triangulated meshes can be used to describe the shape of different types of geometry such as bicycles, bridges, or runways. In engineering, such polygon meshes can occur as finite element meshes, resulting from topology optimization or laser scanning. This article presents an automated parameterization of polygon meshes into a parametric representation using subdivision surfaces, especially in topology optimization. Therefore, we perform surface skeletonization on a volumetric grid supported by the Euclidian distance transformation and topology preserving and shape-preserving criterion. Based on that surface skeleton, an automated conversation into a Subdivision Surface Control grid is established. The final mid-surface-like parametrization is quite flexible and can be changed by variating the control gird or the local thickness.
SURVEYING DESIGN SKILL DEVELOPMENT IN WORK-INTEGRATED LEARNING EXPERIENCES: A REVIEW OF THE LITERATURE
Authors: Litster Gregory , Hurst Ada , Pretti T. Judene 
Published: August 2021

AbstractWork-integrated learning (WIL) is an educational approach that intentionally scaffolds work experiences throughout undergraduate education. This approach has been proven to provide many benefits to students, including increased grade point averages, better job prospects after graduation and skill development. As such, we expect WIL experiences to contribute to engineering student's ability to design, a central aspect of both engineering education and practice. We found little evidence of research related to WIL experiences in the design literature, so we conducted a secondary data analysis on 33 publications from engineering education literature focusing on student WIL experiences with design. The review found evidence of students using a design process and recognizing the importance of designing within context, focusing on health, safety and ethical concerns of being an engineering designer. However, there was little evidence found of what students actually designed (i.e., components, systems or processes). We highlight some interesting areas for future research, specifically for design researchers to investigate how student work experiences are contributing to their development of design knowledge, skills and abilities.
SUSTAINABILITY THROUGH THE DIGITALIZATION: EXPLORING POTENTIALS AND DESIGNING VALUE CO-CREATION ARCHITECTURES FOR PRODUCT-SERVICE-SYSTEMS
Authors: Scholtysik Michel , Reinhold Jannik , Koldewey Christian , Dumitrescu Roman 
Published: August 2021

AbstractDigitalization and sustainability are major challenges for today's manufacturing industry. While digitalization is characterized by the incorporation of digital technologies in the products and services as well as the value creation architectures, sustainability requires them to balance economic, environmental and social issues. In both areas, especially Product Service Systems (PSS) are constantly gaining importance. This results in so called smart PSS that integrate digital technologies as well as sustainable PSS which aim at a positive impact on sustainability. Both two concepts cannot be clearly delimited since smart PSS might be designed for sustainability as well and sustainable PSS might be used with digital technologies. This paper aims to investigate the interrelations. To that, digitalization patterns of products and services are evaluated regarding their sustainable impact. The evaluation is conducted by a survey in research and industry. Furthermore, the design of the underlying value creation architecture is investigated. Here, a methodology is proposed enabling companies to optimize their value creation architecture.

Published: August 2021

AbstractPackaging waste has become a significant problem in China. The paper stems from growing awareness of packaging and environmental protection.To explore the perception of Chinese consumers on packaging and sustainability, the research takes Wuzhen as a case, based on the economic situation, industrial advantages and potential for implementing sustainable measures. It also investigates the current situation of packaging design in the town. By using empirical analysis in the form of questionnaire and semi-structured interview, the survey was carried out from three aspects: tourist attitude towards shopping products in Wuzhen, tourist perceptions of packaging characteristics, tourist perceived importance of sustainable. In the end, the paper discusses the packaging design of Wuzhen from the perspective of materials, function and design. This research is aimed to explore Chinese consumers' views of packaging and environmental sustainability and provide insights to the packaging industry to further enhance the effectiveness of environmentally packaging.
