Abstract: The luxury fashion market is rapidly expanding worldwide, and the demand for designer pyjamas is on the rise. Pyjamas originated in South Asia as loose, lightweight trousers or two-piece suits for sleeping and lounging, and evolved into swishy palazzo-like pants and jumpsuit styles popular in Europe. Over time, pyjamas have undergone multiple functional and aesthetic changes while the luxury fashion goods purchasing power of Chinese millennials who were born in a rapidly evolving digital world has increased fast. However, limited academic research on luxury pyjamas and scarce information on this specific consumer group are available. This study examines the main aesthetic factors that influence Chinese millennial consumers' purchase intention of luxury pyjamas and specifically evaluates the importance of design elements such as artistry, colour, texture, fit, silhouette, innovation, and craftsmanship. An online survey was conducted with 124 Chinese participants via the Chinese social media platform WeChat to determine their aesthetic preferences for luxury pyjamas. The findings reveal that Chinese millennial consumers regard pyjamas as functional items and mainly wear them at home. Aesthetic considerations are the main purchase driver of sleepwear, with the visual texture of pyjamas as the most important aesthetic factor for Chinese millennial consumers, emphasizing the need for product developers to choose exquisite and appealing fabrics. Colour and artistic elements, such as colour collocation and pattern print, also have a significant impact on their purchase intention. This study provides valuable insights for luxury sleepwear developers seeking to enhance the aesthetic design aspects of their products to meet the needs and preferences of Chinese millennial luxury consumers.

Abstract: Successful professionals are expected to adapt to current requirements at all times and keep their knowledge up to date. The Smart Textiles field poses a particular challenge in this respect - in addition to their own specialist knowledge, the focus here is on interdisciplinarity and thinking outside the box. The focus will be on E-Textiles, the combination of electronic with textile products. For this purpose, a flexible Smart Textiles Experience kit called Flex‑STEx is developed using a design thinking approach and involving future users in the development process. This application-oriented construction kit is intended to help extend the limits of individual knowledge, stimulate creativity and provide the ability to initiate product development. A further added value for students will be a deeper understanding of innovation and interdisciplinary challenges. This paper gives an insight into the work in progress concerning the development of this novel kit.

Abstract: The paper presents a development methodology for a new bio-composite medical device used in extensive anatomical reconstructions. Current surgical techniques and devices include auto transplant, surgical meshes or even acellular devices. Due to the high degree of reconstruction and large amount of exposed tissue, the surgeries tend to have high re-intervention rates, leading to severe complications and even death. A functional approach is proposed to develop an improved medical device for the treatment of these severe traumatic lesions. A six step methodology is presented, validating the first three with the development of several concepts. The general need is accurately identified using the APTE instrument and a FAST diagram is constructed for one product existence stage. Nine concepts are generated using the proposed methodology and three were preliminarily kept for development. Further research will be undertaken for manufacturing and testing of the final selected concept.

Abstract: Load-carrying systems often suffer from unexpected disruptions which can cause damages or system breakdowns if they were neglected during product development. In this context, unexpected disruptions summarize unpredictable load conditions, external disturbances or failures of system components and can be comprehended as uncertainties caused by nescience. While robust systems can cope with stochastic uncertainties, uncertainties caused by nescience can be controlled only by resilient load-carrying systems. This paper gives an overview of the characteristics of resilience as well as the time-dependent resilient behaviour of subsystems. Based on this, the adaptivity of subsystems is classified and can be distinguished between autonomous and externally induced adaption and the temporal horizon of adaption. The classification of adaptivity is explained using a simple example of a joint brake application.

Abstract: This contribution firstly presents results gathered during the development of a lightweight multifunctional trailer made of composite material. Focusing on various cross country activities, such as mountain biking, hiking or trail running, significant technical improvements compared to existent products were obtained. This includes technical features like an integrated design to reduce accelerated mass, increase flexibility and provide shock suspension for the child carried during sports activities. As a key feature of the trailer, an agile steering system was engineered to both fit the specific requirements during the trailer’s use as a stroller and as a baby jogger. Due to the integrated design the weight of the single child prototype trailer was reduced by up to 50 % compared to conventional models and the driving comfort was considerably increased. To evaluate both the safety of the carried child during sports activities and the comfort for the adult as well as - last but not least - the resulting fun of those both users during sports activities a series of test rides was conducted. Selected results of the developed measuring setup and test track design are presented in this paper. Finally gathered measurement data are discussed and further design improvements are derived.

Abstract: A new approach for the analysis of high pressure die casting geometries concerning form filling is introduced. It enables the reduction of simulation cycles needed in the product development process, as they are highly time and cost intensive. Therefore, we developed an analysis tool, which uses shortest paths from each part of the geometry to the chosen ingate surfaces. This way, and by evaluating the information given by basic filling simulations, we can evaluate the usability of a given geometry for a high pressure die casting process and are able to suggest useful strategies to place ingates and to design a filling system.

Abstract: From a technological point of view Industry 4.0 is already at an advanced stage. However, it still needs time to implement aspects of Industry 4.0 into the everyday life of project work. A major cause is the lack of methodologies in this area. Production-related areas must be prepared to identify the requirements and needs of Industry 4.0, right from the planning phase of the project. This paper describes an approach to create an Industry 4.0 Project-Roadmap as a base of important strategical decisions. Using the VDMA industry 4.0 toolbox, innovative ideas are developed, structured and finally prioritized considering effort and costs. The result is a roadmap, which allows the design of basic Industry 4.0 equipment of the project as well as to integrate further features as options. Due to different target groups and a very specific expectation the workshop procedure is modified to the already by the VDMA published guideline and presented in detail below.

Abstract: The increasing demand for product individualization and the challenges of globalization force manufacturing companies to expand their product range while keeping internal expenses low. To tackle the dichotomy between economies of scale and economies of scope, companies make use of modular product platforms and carry-over-parts. To improve the modular platform performance, it is crucial to define its structure in the early planning phase. In vertical direction, the modular platform structure defines considered technical solutions, whereas in horizontal direction, it is characterized by the products that use these solutions. When introducing or adapting modular product platforms of complex product portfolios, companies often make upfront decisions regarding the modular platform’s structure based on expert intuition. This mainly results from a lack of time, organizational restrictions and missing systematic approaches. The sheer number of product data associated with the products in the portfolio as well as the often missing transparency regarding existing components and interfaces force decision makers to decide in an intuitive approach. However, this hinders an optimal design of modular platforms and reduces the optimal performance exploitation. In order to increase modular platform performance and hence the company´s profitability, a holistic approach prior to the actual platform design process is required to determine the optimal modular platform structure for a complex product portfolio. The basis for this methodology is a generic descriptive model, which helps to describe current and planned products of a serial manufacturer’s portfolio in a structured way. The introduced methodology determines optimal modular platform scopes through systematic identification of anchor products by aid of Data Mining.

Abstract: Today’s manufacturing companies are exposed to the challenge of fulfilling constantly growing and heterogeneous customer expectations. Simultaneously, the demand for delivering the highest quality in shortest time increases strongly. One way to handle these requirements is the highly iterative product development approach. By distributing development processes in short and iterative sub-processes, this method generates customer oriented and marketable products. However, most producing companies fail by trying to adopt the short-cycled concept without considering the suitability of these methods for the respective project. According to that fact, this paper aims at the presentation of a methodology which shows how to evaluate and select highly iterative product development methods for individual development scopes. A first application of this methodology indicated affirmative results regarding to the practicability within a startup enterprise. Still, there is need for further research, especially in the field of implementation.
