Item type:Publication, Access status: with files , Optimization of the potting design using an approach for load path optimized designs of sandwich structures(Cambridge University Press (CUP), 2024-05); ; In sandwich structures, mass can be reduced or mechanical properties increased if the challenging local load distribution can be improved. Through numerical optimizations, novel designs can be determined and investigated in physical and virtual tests. This paper presents an approach for load path-optimized design of sandwich structures and novel design concepts. The approach is applied to the design concept of honeycombs filled with potting compound. Due to the shown transferability to higher structural levels, it can be used as a basis for the design optimization of any sandwich structure.Publicationtype: Conference Paper14 87 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Systems engineering in design practice: a guideline for development service providers(Cambridge University Press (CUP), 2024-05); To handle the increased complexity within the automotive industry, this paper introduces a guideline, which aims to support development service providers to examine the introduction and if applicable support the introduction of systems engineering. The initial verification was performed through applying the guideline at Porsche Engineering as an exemplary service provider. As a result, the success factors "knowledge basis" and "knowledge transfer" have been improved by two points on a 1-5 Likert-scale by introducing a SE process-specific knowledge platform and a defined knowledge transfer.Publicationtype: Conference Paper26 40 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Supporting modular product family representations by methodically utilising meta-models(Cambridge University Press (CUP), 2024-05); ; ; Due to the rising multidisciplinarity and connectivity of products especially modular product families, a sophisticated handling of the information is crucial for reducing complexity during the development. System modelling techniques have evolved to assist engineers with managing information. However, nowadays, it is rarely focusing on modular product families. This paper introduces a meta-model based on an ontology, which improves the creation and management of modular product family and its occurring data. The meta-model is presented using the example of a Passenger Service Unit (PSU).Publicationtype: Conference Paper37 46 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Data-driven life cycle assessment for mechatronic systems: a comparative analysis of environmental impact assessments(Cambridge University Press (CUP), 2024-05); ; ; ; The growing emphasis on sustainability integrates eco-design and life cycle analysis into product development. Despite the value of LCAs, data limitations lead to assumptions, impacting accuracy. This study compares an estimation-based LCA with a data-driven approach, focusing on a laser machine's operational phase. The significant influence of resource consumption during operation underscores the necessity of optimization. Applying a data-driven approach reveals a 24% difference compared to the estimation-based method, emphasizing the challenges in obtaining accurate data for effective LCAs.Publicationtype: Conference Paper67 77 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Enhancing design representations of information and knowledge of complex and long-living assets by applying system modelling techniques(Cambridge University Press (CUP), 2024-05); ; Managing general domain knowledge and asset-specific information in the form of digital representations is especially important and challenging when focusing on long-living and complex assets. Implicit knowledge and existing structures need to be captured and digitalised, ideally without introducing unnecessary complexity through unfamiliar wording or new structures. To achieve this, a methodical approach that utilises ontologies as well as system modelling techniques and focuses on early-stage model instantiation is presented and applied to the cabin retrofit of aircraft.Publicationtype: Conference Paper24 37 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Applying a product modularization approach on the case of a battery pack(Cambridge University Press (CUP), 2024-05); ; ; ; Hein, EugenWhen designing battery packs, opposing target-conflicts and design goals arise due to the different disciplines involved in the development process. Looking at the available technologies for battery pack design, different solutions can be found on the market. The development of a battery pack for use in various scenarios therefore presents an interesting use case to evaluate product modularisation approaches. Hence, this paper discusses the application of the Integrated PKT Approach based on a fictious use case of a modular battery pack to derive potential starting points for its improvement.Publicationtype: Conference Paper47 57 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Product changes from various viewpoints along the product lifecycle – an empirical studyFrom an economic perspective, the appeal of a product diminishes over time. However, volatile markets and divergent technological advancements make it challenging to anticipate when and to what extent changes will be necessary. Therefore, it is important to be able to integrate changes after a product's launch. This paper provides an overview of different perspectives on the product lifecycle. In addition, the paper presents an empirical study on implementing changes at an automobile manufacturer.Publicationtype: Conference Paper29 41 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Towards a method for human-centred analysis of external varietyAddressing VUCA challenges in product development, the Human-Centred Analysis of External Variety (HAV) method is introduced. Focusing on the early stages of new product development, HAV provides a structured approach, reducing uncertainty through quick market analysis, customer engagement, and goal setting. HAV is illustrated using a cargo bike product family case study and emphasizes its role in aligning human-centred methods with project goals. The first steps of the HAV method are presented, but also the need for further action towards a validated and elaborated method is discussed.Publicationtype: Conference Paper18 41 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Printing study and design guideline for small hollow structures in medical technology(Cambridge University Press (CUP), 2024-05); ; ; In recent years, interest in additive manufacturing has increased. To overcome challenges such as the correct use of the technology, guidelines are needed to help the user in the fabrication process. However, such guidance is not currently available for all applications. This paper dives into design methods in AM and their transfer to an application example in the field of medical technology. The aim of this paper is to analyse the transferability of a design method for vessel models to small vessel models. To this end, an initial printing study is carried out on simplified hollow structures.Publicationtype: Conference Paper23 39
