AUTOMATED PART DECOMPOSITION FOR PRODUCT ARCHITECTURE MODELING
Authors: Redeker J. , Gebhardt P. , Reichler A.-K. , Türck E. , Dröder K. , Vietor T. 
Published: June 2020

AbstractThis paper presents an algorithm that contributes to an automatic decomposition of a mechanical part based on geometric features and methods of unsupervised machine learning. For the development of the algorithm, existing techniques of 3D shape segmentation, especially surface-based part segmentation procedures are reviewed and important areas of activities are revealed. The developed multi-step approach results in an abstract product model. This representation leads to a new way of designing and redesigning parts for the novel hybrid manufacturing concept Incremental Manufacturing (IM).
WHAT IS A DIGITAL TWIN? – DEFINITIONS AND INSIGHTS FROM AN INDUSTRIAL CASE STUDY IN TECHNICAL PRODUCT DEVELOPMENT
Authors: Trauer J. , Schweigert-Recksiek S. , Engel C. , Spreitzer K. , Zimmermann M. 
Published: June 2020

AbstractOver the last two decades, a concept called Digital Twin has evolved rapidly. Yet, there is no unified definition of the term. Based on a literature study and an industrial case study, an overarching definition of Digital twins is presented. Three characteristics were identified – representation of a physical system, bidirectional data exchange, and the connection along the entire lifecycle. Further, three sub-concepts are presented, namely: Engineering Twin, Production Twin, and Operation Twin. The presented paper thus formulates a consistent and detailed definition of Digital Twins.
MODELLING THE GENERATIVE POWER OF SERVICE DESIGN PRACTICE THROUGH THE REFINED LANGUAGE OF THE “C-K THEORY”
Authors: Dragicevic N. , Lee W. B. , Tsui E. , Chew E. 
Published: June 2020

Abstract“C-K theory”, a theory of reasoning in design, offers a formal modelling language with the power to describe the unfolding of creativity and the generation of new innovative objects as integral parts of design practice. However, the theory has limited ability to analyze and describe the particulars of design practice when the target area is service. To address this question, the purpose of this paper is to refine the “C-K theory” by embedding service relevant constructs and exploring strategies for enhancing the creative engagement resulting in the innovative service concepts.

Authors: Montero J. , Weber S. , Bleckmann M. , Paetzold K. 
Published: June 2020

AbstractAdditive Manufacturing is doing its first steps in the production of spare parts. Usually the spares belong to legacy systems, and the tooling to produce them is no longer available. Re-designing spares that are designed for a previous industry mindset can be sometimes challenging. In this study a rather classic design approach is compared to a functional driven approach. Four case studies from different clients are reported, remarking the benefits and drawbacks of using design for additive manufacturing practices in Laser Powder Bed Fusion.

AbstractThe maintenance of an industrial plant is mainly based on analogue and manual methods and processes. In the future, the maintenance data of the real object should be determined digital and transferred to a PDM system in real time. This is made possible with a digital method of component identification. This publication presents a system-based component identification using Mixed Reality. Coordinates are determined by the terminal device and compared with a reference structure. After successful identification, maintenance data can be determined and automatically transferred to a PDM System.
CONCEPTION OF A DIGITAL TWIN IN MECHANICAL ENGINEERING – A CASE STUDY IN TECHNICAL PRODUCT DEVELOPMENT
Authors: Schweigert-Recksiek S. , Trauer J. , Engel C. , Spreitzer K. , Zimmermann M. 
Published: June 2020

AbstractA Digital Twin as a virtual representation of a physical system is becoming a key technology. While potential benefits are evident, there is no approach in literature or practice comprehensively supporting its introduction. In an industrial case study, a generic procedure model for the conception and implementation of a Digital Twin was developed. The relations between use cases, usage data, and virtual models resulted in a target concept as well as requirements for the implementation. Thereby, companies can access the potentials of a Digital Twin taking into account their specific situation.
DESIGN THINKING TO ENHANCE REQUIREMENTS ANALYSIS IN SYSTEMS ENGINEERING
Authors: Batista J. , Hassan A. , Bonjour E. 
Published: June 2020

AbstractSystems engineering (SE) is a general methodological approach that includes all relevant activities to design, develop and verify a system. This work was based on the need to enhance the integration of the customer needs into the design phases of SE. A joint methodology was proposed integrating the SE approach with the Design Thinking (DT). An analysis was conducted as part of a case study proposed by IBM Corporation for the development of a security system for a building. The results confirm that the insertion of the DT in the SE has a significant impact on the generation of concept solutions.
A METHODICAL APPROACH TO INTEGRATED PRODUCT DEVELOPMENT IN TOTAL HIP ARTHROPLASTY
Authors: Ley P.-P. , Wirths L. , Oleff C. , Jungreitmayr F. , Vajna S. , Paetzold K. , Borg J. C. 
Published: June 2020

AbstractHip joint arthroplasty is considered to be a safe, successful and cost-effective procedure to restore hip joint functionality. However, a successful hip joint arthroplasty affects different stakeholders e.g. patient and surgeon and depends on various influencing factors within the product life cycle as well as the applied technological opportunities. Due to the complex dependencies between influencing factors, technological opportunities and stakeholders, this contribution introduces an IPD-based approach to improve the quality of total hip arthroplasties.
AN INVESTIGATION OF A GENERATIVE PARAMETRIC DESIGN APPROACH FOR A ROBUST SOLUTION DEVELOPMENT
Authors: Li H. , Brockmöller T. , Gembarski P. C. , Lachmayer R. 
Published: June 2020

AbstractThe main design activity in engineering practice is to adapt existing designs or to create variants of existing products to new demands, which require a robust model against both parametric and topological changes. To design such a kind of model becomes a big challenge, especially in the development of structural components due to the number of load application points, variable load cases and restrictions from manufacturing technologies. Thus, the generative parametric design approach is applied to generating high dynamic product models, allowing them to be adjusted for changes feasibly.

Authors: Gräßler I. , Thiele H. , Scholle P. 
Published: June 2020

AbstractAs time-to-market is getting shorter, customer needs have to be identified as early as possible in product development. Correctly applied, corporate foresight can give a glimpse into the future to anticipate such needs and thus gain a competitive advantage. A support tool to choose the appropriate method of foresight is not available yet. Thus, a literature study on foresight methods in industry is performed and a novel decision support tool is proposed which avoids high entrepreneurial risks. Based on the findings, potentials for future work are identified for different types of methods.
IMPROVING SCENARIO-TECHNIQUE BY A SEMI-AUTOMATIZED CONSISTENCY ASSESSMENT BASED ON PATTERN RECOGNITION BY ARTIFICIAL NEURAL NETWORKS
Authors: Gräßler I. , Scholle P. , Thiele H. 
Published: June 2020

AbstractTo enhance the success of innovations, various methods for foresight have been developed. Automatization yields the potential of shifting effort away from the process to the actual in-depth analysis of resulting scenarios in scenario-technique. Within this paper, an approach based on a user-specific classification of input factors (consistency values) is presented. Generic consistency patterns used for a semi-automatized consistency assessment based on artificial neural networks are identified using a case study approach. Hereby, the effort for scenario-technique can be reduced significantly.

ACHIEVING SIMPLICITY: A CONSIDERATION OF A SYSTEMATIC APPROACH
Authors: Pilz F. , Vajna S. , Schabacker M. 
Published: June 2020

AbstractDesign principles from the field of design engineering require that a product be designed as unambiguous, safe and simple as possible. Simplicity results on the one hand from an objective product-relevant side, on the other hand from the experience and knowledge of the user. A product that is perceived as simple by one person may seem complicated to another. From this, the questions arise, with which attributes simplicity can be described and how these are to be captured. In this paper, an evaluation system for the subjective attributes of simplicity is created using the fuzzy sets approach.
SEMANTIC ANALYSIS OF ENGINEERING DESIGN CONVERSATIONS
Authors: Georgiev G. V. , Georgiev D. D. 
Published: June 2020

AbstractTo objectively and quantitatively study transcribed protocols of design conversations, we apply a semantic analysis approach based on dynamic semantic networks of nouns. We examined the applicability of the approach focused on a dynamic evaluation of the design problem solving process in engineering design educational settings. Using a case of real-world case, we show that the approach is able to determine the time dynamics of semantic factors such as level of abstraction, polysemy, information content, and quantify convergence/divergence in engineering design conversations.

Authors: Beste C. , Welo T. , Olsson N. 
Published: June 2020

AbstractThere is little tolerance for deviation in time, budget and quality in the execution of product development projects. On the other hand, the project environment is gaining complexity. Changes on project scope are daily business. We set up an initial hypothesis, that unplanned changes -newness- has negative impact on projects. We developed and executed therefore a survey about factors belonging to innovation, complexity and newness to test their perceived impact on project success. Our data show a positive correlation between unsuccessful projects and newness, which is discussed in the paper.

Authors: Aflatoony L. , Lee S. J. 
Published: June 2020

AbstractThere are currently limited guidelines on how to design complex assistive technologies (ATs), which necessitates expertise beyond that possessed by designers, occupational therapists (OTs), or end-users. To address this issue, we conducted a series of four participatory workshops to study various configurations of OT-designer-user collaboration in co-designing do-it-yourself (DIY) ATs for an older adult with mobility impairment. We then proposed a specific co-design framework for such OT-designer-user collaboration.

PARTITIONING TYPES IN PRODUCT MODULARISATION
Authors: Pakkanen J. , Lehtonen T. , Juuti T. 
Published: June 2020

AbstractAlternative ways to divide the product into modules, partitioning types, have been identified. The research material consists of the modularisation exercise at the university. Students modularised LEGO wheel loaders for product configuration. We began to see certain basic principles for partitioning the product into modules. From these, we compiled a collection of partitioning types. Similarities between the identified partitioning types and the literature exists. Future research is concerned with whether identified partitioning types would also support modularisation in industrial projects.
SIMULATION OF GRADIENT-BASED INDIVIDUAL DESIGN BEHAVIOUR IN DISTRIBUTED DEVELOPMENT PROCESSES
Authors: Wöhr F. , Stanglmeier M. , Königs S. , Zimmermann M. 
Published: June 2020

AbstractAs current vehicle development processes in the automotive industry are highly distributed, the interaction between design teams is limited. In this paper we use a simulation in order to investigate how the rate of design team interaction affects the solution quality and development cost. Results show, that in case of no limiting constraints, a low rate of interaction yields the best results regarding solution quality and development cost. If design activities are affected by constraints, however, the rate of interaction is subject to a conflict between solution quality and development cost.
CONCEPTUAL MODEL FOR (SEMI-) AUTOMATED DERIVATION OF EVALUATION CRITERIA IN REQUIREMENTS MODELLING
Authors: Horber D. , Schleich B. , Wartzack S. 
Published: June 2020

AbstractRequirements act as a limitation of the solution space, which represents the stakeholders’ needs and guides the whole product development process. Therefore, forgotten requirements can lead to wrong decisions when using them as a basis for decision-making. This contribution introduces a novel approach to link the requirement and evaluation criteria models to address this problem. For setting up those criteria consistently, the requirements are classified using natural language processing and derived by a ruleset based on a developed mapping between requirement classes and criteria types.
CONCEPT COMPARISON: A FUNCTION INTEGRITY INDICATOR
Authors: Wichmann R. L. , Eisenbart B. , Gericke K. , Lux B. 
Published: June 2020

AbstractComparing the propensity for risk in concepts with little commonality, such as different working principles, different number of functions and components, is challenging to achieve in a systematic and traceable manner. This paper builds on the Function Integrity Diagnosis and Documentation method to introduce a Function Integrity indicator as a means to quantitatively compare dissimilar design concepts based on risk assessment. The proposed indicator is intended to support designers converge on a suitable design concept based on considerations of risk to concept functions.

USING KINEMATIC ANALYSIS TO DEVELOP A NEW TOOTH SYSTEM FOR GEARINGS WITH VARIABLE SHAFT ANGLE
Authors: Grafinger M. 
Published: June 2020

AbstractThe belt units of an omnidirectional treadmill need to be connected for a continuous rotational transmission with variating axes angle. Torus gearing is not appropriate due to kinematic reasons, therefore a crown gearing with cone-shaped teeth is proposed. Parameter analysis on a virtual kinematics model show that depending on the cone angle, overlaps occur at different axis angles. Consequently, the shape of the teeth is modified with tip and foot relief and optimized so that no overlapping of the teeth occurs while a large path of contact is provided.
