Contemporary product designers seek to create products that are not only robust for the current marketplace but also flexible for future changes, adaptations, and evolutions. This type of product flexibility is distinctive from mass customization, product architecture of singular products, and product families. The intent is to design products that intrinsically enable future changes even though such changes may not be known or planned in the current product offering. To accommodate product flexibility of this type, research advancements are needed in terms of fundamental design principles and evaluation methods for predicting and improving the flexibility of a product. This paper presents advancements in both areas. We first present the systematic enhancement of a flexibility assessment tool referred to as CMEA, Change Modes and Effects Analysis. CMEA provides the basic ability to assess the flexibility of a product, with analogous features to the well-known Failure Modes and Effects Analysis. Our enhancements extend the method to provide for intuitive and more repeatable measures of flexibility. We then use the enhanced CMEA to investigate a variety of consumer products with the goal of inductively deriving product flexibility principles. Concrete applications are shown for these principles from the domain of power yard tools, such as hedge trimmers, weed trimmers, and leaf blowers. Also, the applications are used to demonstrate the value of the CMEA enhancements.

The design of modular product families enables a high external variety of products by a low internal variety of components and processes. This variety optimization leads to large economic savings along the entire value chain. However, when designing and selecting suitable modular product architecture concepts, often only direct costs are considered, and indirect costs as well as cross-cost center benefits are neglected. A lack of knowledge about the full savings potential often results in the selection of inferior solutions. Since available approaches do not adequately address this problem, this paper provides a new methodological support tool that ensures consideration of the full savings potentials in the evaluation of modular product architecture concepts. For this purpose, the visual knowledge base of the Impact Model of Modular Product Families (IMF) is used, extended and implemented in a model-based environment using SysML. The newly developed Sys-IMF is then applied to the product family example of electric medium-voltage motors. The support tool is dynamic, expandable and filterable and embedded in a methodical procedure for knowledge-based decision support. Sys-IMF supports decision makers in the early phase of interdisciplinary product development and enables the selection of the most suitable modular solution for the company.

AbstractBy developing and using modular product families, large savings can be achieved through reuse and combinability along the entire value chain of a company. Since these potentials often have a very long-term character, the lifetime of a modular product family should be as long as possible. Change drivers, such as changing customer and production requirements, however, result in changes having to be made to the initially developed modular product family, which not only causes a great effort but also prevents the long-term benefits from being fully exploited. With the Change Allocation Model, we introduce a tool that makes it possible to align the essential future changes to the product architecture and to identify and redesign the change-critical components taking into account the existing component variety of the product family. This enables future changes in variety to be considered in the product architecture and a future robust modular product family to be developed. The new visualization is illustrated using the example of a product family of pressure regulating valves and is finally discussed with regard to further potentials and challenges.

AbstractOne of the arguments against an increased use of repair is that, due to the constantly growing progress, an often already outdated component would be restored. However, refurbishment also allows a component to be modified in order to upgrade it to the state of the art or to adapt it to changed requirements. Many existing approaches regarding Design for Upgradeability are based on a modular product architecture. In these approaches, however, only the upgradeability of a product is considered through the exchange of components. Nevertheless, the exchange and improvement of individual component regions within a refurbishment has already been successfully carried out using additive processes. In this paper, a general method is presented to support the reengineering process, which is necessary to refurbish and upgrade a damaged component. In order to identify which areas can be replaced in the closed system of a component, the systematics of the modular product architecture are used. This allows dependencies between functions and component regions to be identified. Thus, it possible to determine which functions can be integrated into the intended component.

Product modularization aims to improve the overall design, manufacturing, operational, and post-retirement characteristics of products by designing or redesigning the product architectures. A successful modular product can assist the reconfiguration of products, while reducing the lead-time of design and manufacturing and improving the ability for upgrading, maintenance, customization and recycling. This paper presents a new modular design method called the House Of Modular Enhancement (HOME) for product redesign. Information from various aspects of the product design, including functional requirements, product architecture and life cycle requirements, is incorporated in the method to help ensure that a modularized product would achieve the objectives. The HOME method has been implemented in a software system. A case study will be presented to illustrate the HOME method and the software.

Companies producing in high-wage countries are increasingly challenged due to the necessary differentiation and cost pressure. The modular product platform approach is more and more used by these companies for structuring their product range in order to realise and deploy commonalities. This type of product architecture enables companies to produce nearly individual products without losing economies of scale across the product range. Economies of scale due to communalities result in decreased process costs, reduced development lead-time by uncoupling the development of modules and products as well as the augmentation of the technical product robustness. However, the design of modular product platforms itself causes new challenges regarding the product structuring, the process and organizational design. Recent approaches for the development of communalities through modular product platforms are focusing only the product itself. Since costs are mainly determined in the development phase but caused later in the production phase both product and production have to be taken into account. Furthermore, modular product platforms have a higher variety and diversity of elements since they represent the components, modules and functions of the entire product program. This paradigm shift from an integral product design to a modular product structure cannot be controlled with existing models and methods. Our paper confirms commonality has to be optimized by focusing both the product and production. Therefore we have designed a descriptive framework (commonality model) to display and optimize the commonality both in the product and the process. Furthermore, a product architecture development process that is superior to the individual product development processes was developed for the systematic design of commonalities. The approach presented in this paper focusses on the interactions between product and process parameters. In our approach these interactions will first be displayed based on the graph theory and then be optimized applying sensitivity analysis. By varying relevant parameters both on the product and process side constitutive features can be derived determining product and process standards in order to enhance the overall commonality level.

Optimal Set

The architecture of a product is determined by both the elements that compose the product and the way in which they interact with each other. In this paper, we use the design structure matrix (DSM) as a tool to capture this architecture. Designing modular products can result in many benefits to both consumers and manufacturers. The development of modular products requires the identification of highly interactive groups of elements and arranging (i.e. clustering) them into modules. However, no rigorous DSM clustering technique can be found in product development literature. This paper presets a review of the basic DSM building blocks used in the identification of product modules. The DSM representation and building blocks are used to develop a new DSM clustering tool based on a genetic algorithm (GA) and the minimum description length (MDL) principle. The new tool is capable of partitioning the product architecture into an “optimal” set of modules or sub-systems. We demonstrate this new clustering method using an example of a complex product architecture for an industrial gas turbine.
