Authors: Revfi Sven , Kaspar Jerome , Vielhaber Michael , Albers Albert 
Published: July 2019

AbstractShortening product development cycles while improving cost efficiency and quality epitomize a key challenge in today's competitive market environment. Integrated approaches simultaneously taking into account a conceptual design, material and processing definition methodologically facilitate the progress of promising product solutions most effectively. However, assorted approaches in the field of lightweight design as well as material selection mostly trying to cover alternative solutions on a component-specific level exclusively, yet.Thus, this contribution outlines a cross-component material selection for function-based lightweight design within the Extended Target Weighing Approach covering the identification and evaluation of lightweight design potentials. The developed method is based on Ashby's material selection additionally taking into account project objectives for mass, costs and CO2 emissions in individual functional design spaces. Resulting in material combinations fitting to clearly stated project targets, the product engineer is already supported in an early phase of product development when initially assessing feasible materials for the overall system development.

Published: July 2019

AbstractThe Engineering Design field is growing fast and so is growing the number of sub-fields that are bringing value to researchers that are working in this context. From psychology to neurosciences, from mathematics to machine learning, everyday scholars and practitioners produce new knowledge of potential interest for designers.This leads to complications in the researchers’ aims who want to quickly and easily find literature on a specific topic among a large number of scientific publications or want to effectively position a new research.In the present paper, we address this problem by using state of the art text mining techniques on a large corpus of Engineering Design related documents. In particular, a topic modelling technique is applied to all the papers published in the ICED proceedings from 2003 to 2017 (3,129 documents) in order to find the main subtopics of Engineering Design. Finally, we analyzed the trends of these topics over time, to give a bird-eye view of how the Engineering Design field is evolving.The results offer a clear and bottom-up picture of what Engineering design is and how the interest of researchers in different topics has changed over time.
A Matrix-Based Approach to Investigate the Geometrical Dependencies between Non-Driving-Related Tasks and Future Vehicle Concepts
Authors: Seebach Niko , Rück Marcel , Arlt Frank , Bender Beate 
Published: July 2019

AbstractCaused by the technology of automated driving the user is temporarily released from driving and can perform non-driving-related tasks (NDRTs), such as sleeping or working. The aim of this paper is to describe the geometrical interdependencies between NDRTs and different vehicle types, to be able to integrate them in the geometric package of the early phase of the vehicle conception. To address the objective a literature based study of existing approaches for vehicle conception and NDRT-studies was carried out. Additionally interviews with n=15 experts from the automotive conception department and a databased analysis of n=259 vehicles was conducted. Based on these investigations 91 geometrical characteristics for NDRTs and vehicle types werde determined and combined through a matrix-based approach. By analysing the approach highly connected characteristics such as the torso angle were identified and equations were set up to describe the relations. The approach can be used for different NDRTs such as relaxing and working and different vehicle types such as sporty cars or SUVs in order to integrate them into the package.
Towards Holistic Energy-Efficient Vehicle Product System Design: The Case for a Penalized Continuous End-of-Life Model in the Life Cycle Energy Optimisation Methodology

Published: July 2019

AbstractThe Life Cycle Energy Optimisation (LCEO) methodology aims at finding a design solution that uses a minimum amount of cumulative energy demand over the different phases of the vehicle's life cycle, while complying with a set of functional constraints. This effectively balances trade-offs, and therewith avoids sub-optimal shifting between the energy demand for the cradle-to-production of materials, operation of the vehicle, and end-of-life phases. The present work describes the extension of the LCEO methodology to perform holistic product system optimisation. The constrained design of an automotive component and the design of a subset of the processes which are applied to it during its life cycle are simultaneously optimised to achieve a minimal product system life cycle energy. A subset of the processes of the end-of-life phase of a vehicle's roof are modeled through a continuous formulation. The roof is modeled as a sandwich structure with its design variables being the material compositions and the thicknesses of the different layers. The results show the applicability of the LCEO methodology to product system design and the use of penalization to ensure solution feasibility.
Development of a Configure-to-Order-Based Process for the Implementation of Modular Product Architectures: A Case Study
Authors: Seiler Florian Michael , Greve Erik , Krause Dieter 
Published: July 2019

AbstractAs todays’ global market trends lead to an increasing demand for individualised products, manufacturers need to cope with a high degree of internal and external variety, which has a severe impact on complexity and therefore -costs. When implementing modular product architectures, it becomes obvious, that the actual Engineer-to-Order (ETO) processes cannot cope with the requirements of such a product architecture. It is crucial to develop a complying Configure-to-Order (CTO) process in order to make full use of its suppled benefits. As there is no existing approach about how to methodically change an existing ETO process into an adequate CTO process, we intend to fill this gap with this paper by showing an approach for the development of a CTO process for modular product architectures. Furthermore, we show the application and evaluation of this approach in a case study with a special equipment manufacturer (SME), that is already implementing modular architectures.
Towards an Uncertainty Framework for Product Service Systems of Systems
Authors: Fakhfakh Sarra , Hein Andreas Makoto , Jankovic Marija , Chazal Yann 
Published: July 2019

AbstractProduct Service Systems (PSS) are increasingly complex and collaborative. For instance, manufacturing companies, service providers, and other companies collaborate and jointly develop and operate a PSS (ex: smart grid), where its constituent elements are managed and operated independently. Managerial independence and operational independence are commonly considered key characteristics of a System of Systems (SoS). Hence, a collaborative PSS exhibits System of Systems (SoSs) characteristics. These systems have previously been introduced as Product Service Systems of Systems (PSSoSs). In this paper, we propose to identify relevant uncertainties in the PSSoS design process. For this purpose, we go beyond the PSSoS concept definition and propose a comprehensive framework for PSS and PSSoS characterization. Moreover, based on both a literature review and an industrial diagnosis, we identify PSSoSs-specific design uncertainties.
Bio-Inspired Design for Additive Manufacturing - Case Study: Microtiter Plate
Authors: Hashemi Farzaneh Helena , Angele Ferdinand , Zimmermann Markus 
Published: July 2019

AbstractBio-inspired design is an innovative methodology for transferring biological solutions into technical solutions, for example for the design of weight- and load-optimized components. Bio-inspired design therefore offers great potential for meeting the challenges of designing additively manufactured components, such as avoiding warpage, supporting structures and material minimisation. Nevertheless, apart from bio-inspired topology optimization tools, bio-inspired design is rarely used in industrial practice because for many companies the practical applicability up to the prototype is not obvious. The aim of this work is therefore a practical approach to the search for biological systems, analysis, abstraction and transfer of analogies. We apply bio-inspired design on the design of a microtiter plate manufactured by stereolithography, whose dimensional accuracy is impaired by warpage. Here, the venus’ flower basket, a deep-sea sponge, can serve as a model. It has a hierarchical structure of silicate needles whose elements are abstracted for bio-inspired transfer. We show and evaluate the transfer of different analogies using a prototype.

Published: July 2019

AbstractBuilding construction is one of the fastest growing industries in India and it puts a huge burden on its limited natural resources. Fired clay bricks are one of the major constituent materials for the construction industry and it produces a huge amount of greenhouse gases. This research tries to highlight the use of alternative materials and how they can be modulated to suit the Indian construction industry. Bio-brick or agro-waste based brick is one such material that has the potential to be a sustainable and cost-effective solution. It acts as good heat and sound insulator and at the same time has overall negative carbon footprint. Additionally, it also acts as a deterrent to stubble burning, prevalent in northern India which causes severe air pollution. Due to its low density, it reduces dead load in high rise structures, thereby making RCC construction more economical. The study also highlights the use of Bio-brick in various areas of a structure. Another important objective of this research is to inspire and motivate architects, designers, researchers and builders to encourage and support the development of such sustainable and eco-sensitive material in construction industry.

Published: July 2019

AbstractThis paper provides an overview of the state-of-the-art research about creative work and learning environments. We conducted a systematic literature search within the Scopus database and identified a total of 70 relevant sources discussing creative spaces within academic, practice, or other innovation environments. Among the included sources are 48 academic publications and 22 sources from company research and illustrative coffee-table books that are discussed separately. We analyse the academic sources regarding their theoretical contribution, as well as regarding their scope. Finally, the included sources are categorized according to three areas of interest: (1) the addressed space types for different creative activities, (2) abstracted requirements for creative spaces, and (3) concrete characteristics and configurations of a creative space. The results provide an in-depth insight into the current state of research on the topic of creative spaces. Practitioners, educators, and researchers can use the presented overview to investigate the possible impact of creative workspace design and to identify research gaps for conducting further research in the field.
Engineers’ and Biologists’ Roles during Biomimetic Design Processes, Towards a Methodological Symbiosis
Authors: Graeff Eliot , Maranzana Nicolas , Aoussat Améziane 
Published: July 2019

AbstractThe strength of biomimetics comes from its ability to draw from life mechanisms and strategies to design innovative solutions. In spite of recent methodological progresses, more specifically on tools and processes, biomimetics' implementation still faces strong difficulties. Among other things, design teams have a hard time finding and selecting relevant biological strategies. Facing these challenges, we consider an alternative, yet well recognized, approach: the integration of profiles having a training in natural science within biomimetic design teams. As biologists aren't used to work in design teams, there is a need for a process actually guiding their practice in biomimetics and determining the way they will interact with the “traditional” design team. After studying the literature and asking for experts' opinion on the matter, we introduced a biomimetic design process considering this new profile as an integral part of biomimetic design teams. With the final goal of making biomimetics implementable, this proposed theoretical process is currently tested in both a student and an industrial project in order to optimize our methodological contribution with practical feedbacks.
Transparency in Responsible Design: Avoiding Engineering Overconfidence and Supporting Societal Acceptance
Authors: Vermaas Pieter 
Published: July 2019

AbstractIn this contribution it is argued that in responsible design engineers should be transparent towards stakeholders about the goals they intend to realise with their designs. The emergence of responsible design in, e.g., value-sensitive design, design for values, social design, nudging and positive design, is to be welcomed. It has however the weakness of overconfidence which may lead engineers to suspend earlier commitments to society as given in engineering codes of conduct and ethics, and practices of seeking informed consent and taking blame. It is argued that these earlier commitments lead to the requirement that engineers should be transparent about the goals in responsible designs. Providing this transparency support moreover the societal acceptance of responsible design since it positions engineers doing responsible design as subscribing to values such as respect, honesty and trust. I illustrate the argument with a case of social design and a case of nudging.
An Overview and Classification of Tolerance Compensation Methods
Authors: Aschenbrenner Alexander , Schleich Benjamin , Wartzack Sandro 
Published: July 2019

AbstractTechnological advances as well as novel manufacturing and design paradigms, such as industry 4.0 and digitalization, offer new opportunities for innovative products. However, they also increase the product complexity and cause new challenges in the production process. Therefore, agile production approaches are crucial. Tolerance compensation provides more flexibility in the production process, as demands on dimensional accuracy of the components are reduced. As a result, tolerance compensation also offers the possibility of reducing production costs without compromising product quality. Nevertheless, tolerance compensation is often considered a reactive intervention to reduce the number of out-of-spec parts a posteriori instead of including it in the early stages of Geometrical Variations Management. The contribution tackles this issue by characterizing and categorizing different methods of tolerance compensation as well as providing design guidelines for the application of tolerance compensation methods. This enables design engineers to select a suitable tolerance compensation method for different applications.
Analysis of Approaches of Tolerance Allocation regarding to Economic Efficiency
Authors: Gust Peter , Sersch Alina , Steger Tobias , Schluer Christoph 
Published: July 2019

AbstractThe aim of this paper is to examine the current state of research on tolerance-induced costs in Germany. Through a literature research already existing approaches for the determination of costs related to tolerances during the specification of technical components are pointed out and possible approaches for the reduction of these costs are presented. In addition, the actuality of these approaches will be considered. One question that is supposed to be answered here is to what state of standard for the specification of components these approaches can be assigned to. On the other hand, it should be clarified whether the existing approaches are applicable to the currently valid standard system of the Geometrical Product Specification (GPS).Can the economic efficiency of the specifications selected for tolerancing be determined in a technical drawing during the product development process in accordance with GPS on the basis of the current state of research?
New Approach on the Allocation of Wear Allowances - A Case Study
Authors: Schubert Dominik , Rohrmoser Andreas , Hertle Sebastian , Wartzack Sandro , Hagenah Hinnerk , Merklein Marion , Drummer Dietmar 
Published: July 2019

AbstractTo maintain functional tolerances of gear sets over their lifetime, especially in polymer-seel gear sets, the wear behaviour must be considered. The state of the art in wear modelling does not take the run-in behaviour of polymer-metal contacts into account. This results in oversizing of wear allowances in the stationary wear phase and undersizing in the run-in phase. Therefore, a modified wear model is presented in this paper. With this method the issues of over- and undersizing can be eliminated.The method is then applied in a case study to show two things. Firstly, using the presented method the calculated necessary wear allowances were reduced by 30%. Secondly, the effect of surface structures on the wear behaviour was investigated. It is shown that the run-in process is not dependent on roughness in sliding direction, but on overall contact area. Thus, the state of the art, i.e. tolerating only the roughness in sliding direction, is insufficient. Considering the process-induced surface topology during design of gear sets can decrease run-in wear. Together with the optimised wear model, this allows wider manufacturing tolerances and thus lower costs during production.
Robustness Evaluation of Product Concepts based on Function Structures
Authors: Goetz Stefan , Hartung Jonas , Schleich Benjamin , Wartzack Sandro 
Published: July 2019

AbstractDue to the varying environment conditions as well as the manufacturing induced deviations, the properties of products vary. In order to still meet the increasingly tightening of functional requirements, tolerancing as well as Robust Design practices became integral parts of the product development. However, despite the fact that the robustness of a product is mainly determined by its conceptual design in early design stages, these activities are usually carried out at the end of the design process. In order to overcome this shortcoming, this contribution shows a method that supports the selection of robust principal solutions and thus contributes to the design of product concepts, which are less sensitive to variations. The novelty lies in the adaption and combination of robust design criteria for the quantitative robustness evaluation in the conceptual design stage. First the product characteristics, which are relevant for the product robustness are determined on the basis of the function structure. By using an adopted VMEA and a newly developed evaluation matrix, this allows a thorough robustness evaluation of product concepts. The method is exemplary shown for a lifting table.
Exploring the Role of Linguistic Abstraction in Idea-Generation Sessions
Authors: Antoniou Rafaella , Dekoninck Elies , Bonvoisin Jérémy 
Published: July 2019

AbstractFor many years, both academia and industry have been interested in increasing the efficiency of idea- generation meetings. Alex Osborne's (1953) rules for brainstorming are an early attempt to do so, and have extensively been used in engineering design, however their effectiveness has been questioned with recent research, and a need for fundamental research to establish which practices are useful arises. This study is an attempt in investigating linguistic abstraction in idea-generation meetings, in order to establish whether any best practices can be distilled from the language used. Engineering design group meetings were recorded and transcribed, and was analysed using a coding framework which was developed for analysing linguistic categories as well as the ideas that were generated during those meetings. More particularly, the study investigates the average abstractness/concreteness of speech throughout the duration of the meetings, as well as the switching between abstract and concrete language and vice versa while comparing idea-related discourse and non-idea related discourse switching. The coding framework proposed is considered robust enough to carry out further work.

Published: July 2019

AbstractIndustrial companies today must operate in an increasingly competitive world and need to rethink their organization accordingly. First, industrial strategies concerning technical management need to change and develop. If we consider the specific management of the product design process, managers use indicators during the lifecycle of the product concerning quality, cost and lead-times. For example, some new indicators concerning performance metrics related to cooperation issues among the design team are set up. Secondly, managers increasingly need to integrate the user in the early phases of the design process. The main benefit of this approach is that it allows designers to innovate more rapidly and robustly. The aim of this paper is to introduce a new approach making it possible to calculate a performance indicator concerning use design. The new indicator will help management drive the design process through the integration of use in the product, helping to enhance the usability of the future product, and consequently improve innovation.
User Stories Method and Assistive Technology Product Development: A New Approach to Requirements Elicitation
Authors: Zacharias Isabela Cristina Simões , Campese Carina , dos Santos Thiago Bertolini , da Cunha Lorena Pereira , Costa Janaina Mascarenhas Hornos 
Published: July 2019

AbstractRequirements elicitation for assistive technology (AT) product development must be collaborative and systemic. This process must ensure that the needs of all different users are identified. For this, UCD methods introduce different tools that seek user involvement and their needs identification. One method commonly used in software development is User Stories. The aim of this paper is to analyse the use of User Stories for requirements elicitation in an AT product development project. This method was applied with three types of users: patients, companions and occupational therapists. For the involvement of these users, the method was customized and two main adaptations were adopted: the stories were written by the development team and all user needs were identified through observations of interactions between patients and prototype. As a result, the development team was able to identify numerous product requirements to be used in later development phases. These requirements were generated by the user needs identified with User Stories. Thus, the method with necessary adaptations, was efficient for requirements elicitation in the AT product development process.
