Item type:Publication, Access status: with files , Effects of product personalization : considering personalizability in the product architecture of modular product families(American Society of Mechanical Engineers (ASME), 2024-04-01); ; The modularity of a product architecture with standard, variant, and optional modules can be measured by the characteristics of commonality and combinability. Positive and negative effects of a more communal or more combinable structure are summarized and visualized in an impact model. However, due to the megatrend of personalization, the solution space of a modular product architecture needs to be extended to include personalizable modules. What remains unclear till now is how personalization impacts the different life phases. Therefore, this article derives an impact model considering product personalization. First, the modularity property of personalizability is derived, in order to then specifically investigate the effects occurring in the different life phases. Therefore, a literature review is conducted. New effects are found, and the existing effects of commonality and combinability are examined for their validity for personalizability. The findings are then combined with the known effects of commonality and combinability to create a holistic impact model of modular product families. This new model takes personalizable modules into account and can support companies in defining the goals and focus of a modularization project.Publicationtype: Journal Article21 56 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Analyzing Dependencies between Product Architecture and Module DriversA company's business model focuses on delivering personalized products or changing its offering to a Product-Service System impacts the underlying product architecture. Depending on the aim, different product architectures need to be designed. Therefore, modularization utilizing module drivers offers the advantage that additional objectives can be addressed. This contribution identifies module drivers focusing on the architecture design of personalization, collaboration, or PSS, which are not yet known. Analyzing existing literature and empirical findings, dependencies between different module drivers and product architectures are identified. As a result of this contribution, an extended view of module drivers in various product architecture applications is given.Publicationtype: Conference Paper33 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Identifying potentials of product personalization(2022-08); Adapting components and modules within the context of product personalization promises exact fulfillment of individual customer requirements. However, personalization should only be used where it is valuable and manageable. The design of product architectures with personalizable modules has so far received little methodological support. Therefore, a method for personalization-oriented product design is to be developed in the long term. In a first step, it is important to systematically derive potentials for personalization, which can then be examined in terms of value and workload. The aim of this paper is to identify indicators that promote personalization. Additionally, it will be presented how these indications could be applied for a product family. Based on an analysis of the aim of personalization as well as research on variety indicators in the literature and a comprehensive analysis of product families where personalization is already applied, personalization indicators are derived. Personalization is particularly relevant where engineer-to-order solutions are used before, for components already having a high variety and where fit and appearance play a role. With the help of an adapted Module Interface Graph (MIG), the analysis results can be documented and visualized in order to derive personalization potentials. Thus, the approach presented in this article represents a significant element of personalization-oriented product architecture design.Publicationtype: Conference Paper33 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Comparing friction of additively manufactured materials with animal blood vesselsThe replication of blood vessels for training and research purposes is possible with the help of additively manufactured (AM) models. However, a meaningful evaluation of the quality of the haptics, here concentrating on friction characteristics, of additively manufactured blood vessel models compared to human vessels is difficult and often only based on subjective assessments. To enable an objective comparison of friction of different AM materials, tests were performed in which a braided stent was pulled through straight test tubes. The force required to do so was measured. The same test setup was used to examine animal blood vessels so that these results could be compared with the findings of the AM materials. In addition, physicians were asked for their assessment of the haptics concerning friction of different materials. Summarizing the results, for the tested Formlabs materials Flexible 80A and Elastic 50A, it can be stated that Flexible 80A is strongly recommended for the replication of blood vessels - even though it is comparatively smooth. The Elastic 50A should only be used for training with increased difficulty since the models are stickier and a flipping of instruments is possible. Coating the materials only involve effort that is not reflected in the benefits.Publicationtype: Journal ArticleScopus© Citations 1 65 309 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Challenges of modular product families and product personalization - An interview studyModular product architectures have so far solved the conflict between the differentiation demanded by the customer and the standardization preferred by the company. However, customers are becoming increasingly demanding and individual needs can be met less and less adequately with predefined modules. The interview study presented in this paper examines in more detail whether and in how far companies also consider this as a challenge and whether and in how far the strategy of targeted product personalization is a solution. This study shows, in particular, that the expansion of size series through individual parameterization is indeed often carried out, but is not planned and marketed as product personalization. The two greatest challenges of product personalization are seen in the reorganization of the company's structure, strategy and processes, and the targeted planning of personalization scopes in the product architecture. Personalization only succeeds if it is profitable and the implementation costs can be paid off. However, there has not yet been sufficient support for investigating the potentials of personalization for the own product family. The need for future research is highlighted.Publicationtype: Conference Paper50 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Tools for the Variety-Oriented Product-Service System Design(2021-11); ; Megatrends such as globalization and technological advances increase the pressure on manufacturing companies. A possible way out is to provide customized combinations of products and services. These so-called Product-Service Systems (PSS) enable companies to access new markets and can be used to differentiate themselves from competitors. However, providing PSS also creates challenges for companies, for example, an increase in complexity within the company, resulting in higher costs. In the first part of this paper, a literature review is used to identify drivers of complexity in the context of PSS. One of the identified main drivers is a rising variety of components and processes within the company. In order to reduce this internal variety and thus also the variety-induced complexity, new tools for the design of variety-oriented PSS are presented in the second part of this paper. The objective of the tools is to reveal the variety and help to reduce the internal variety of product and service components and processes without restricting the external variety of offerings. The newly developed tools are presented schematically and then the application of the tools on an industrial example is discussed. Finally, an outlook on further research topics is given.Publicationtype: Conference Paper87 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Characteristic-Oriented Complexity Cost Analysis for Evaluating Individual Product Attributes(2021-11); ; Product personalization respectively product individualization promises the exact fulfillment of individual requirements for each customer. In contrast to the customer benefit, a company has to deal with numerous internal product and process modifications due to repeated, customer-specific product adaptions. In this context, product adaptions can affect one or more product characteristics whose attributes need to be adapted according to individual needs. At this point, it is essential to understand and evaluate the personalization workload and the resulting costs caused by a specific adaption of a product characteristics’ attribute. So far, the literature offers little support in the cost-based evaluation of potentially personalization-relevant product characteristics. What is missing is the evaluation of the cost increase, if, instead of variant and customer-anonymously developed attributes, now individualized, customer-specific attributes would be realized. Therefore, a framework for a characteristic-oriented complexity cost analysis for the evaluation of customer-specific attributes is developed in this paper to support the decision-making process for or against the personalization of a product characteristic.Publicationtype: Conference Paper57 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Design of personalized devices—the tradeoff between individual value and personalization workload(Multidisciplinary Digital Publishing Institute (MDPI), 2021-01-01); ; ; ; Personalized medical devices adapted to the anatomy of the individual promise greater treatment success for patients, thus increasing the individual value of the product. In order to cater to individual adaptations, however, medical device companies need to be able to handle a wide range of internal processes and components. These are here referred to collectively as the personalization workload. Consequently, support is required in order to evaluate how best to target product personalization. Since the approaches presented in the literature are not able to sufficiently meet this demand, this paper introduces a new method that can be used to define an appropriate variety level for a product family taking into account standardized, variant, and personalized attributes. The new method enables the identification and evaluation of personalizable attributes within an existing product family. The method is based on established steps and tools from the field of variant-oriented product design, and is applied using a flow diverter—an implant for the treatment of aneurysm diseases—as an example product. The personalization relevance and adaptation workload for the product characteristics that constitute the differentiating product properties were analyzed and compared in order to determine a tradeoff between customer value and personalization workload. This will consequently help companies to employ targeted, deliberate personalization when designing their product families by enabling them to factor variety-induced complexity and customer value into their thinking at an early stage, thus allowing them to critically evaluate a personalization project.Publicationtype: Journal ArticleScopus© Citations 11 204 256
