In this research project, modularization will be investigated in the field of different engineering disciplines and in its interdisciplinary impact. Various experts are interviewed to reconcile academic research and modularization in practice as part of this research project. On the one hand, different strategies and tools are presented and on the other hand, metrics for the optimization of modular architectures are shown. This research project aims at the comparison of different modularization approaches and the discussion of interdisciplinary modularization supported by views from several experts.
The challenges of customizing production, meeting shorter innovation cycles, anticipating volatility in demand patterns that are diffcult to predict, and selling products at competitive production costs in different local markets are forcing companies to adopt innovative production concepts. Modularization is an essential way to reduce internal complexity and costs and represents a central strategy for today's companies by dividing a whole into parts called modules. The increasing diversity in production and the growing influence and interconnectedness of different engineering disciplines within the product architecture make modularization a multidimensional optimization problem. Numerous different strategies and tools come into the picture during the formation of modular product structures.

Excerpt from the Book
2.4.1 Functional and Physical Independence
A possible distinction of modular product architectures results when considering the two dimensions of functional and physical independence. Functional independence means that a component performs a specific function independently of the other components. Physical independence describes the fact that interfaces can separate components physically. Four cases can arise with regard to low and high functional or physical independence (Figure 2).
Modular product architecture comprises closed units that are both physically and functionally independent. A typical modular product is the traditional personal computer. Here, various components such as the screen, keyboard and hard drive each represent relatively functionally and physically independent units. The integral product architecture is the opposite of the modular product architecture. Components of integral products show strong functional and physical dependencies. Product components each fulfill several functions and have interfaces that are difficult to separate. The tablet computer is an excellent example of such an integral product. Here, the screen performs several functions and it is usually not possible to separate the components physically. In the physical modular product architecture, the product has separable interfaces and functions can only result from the interaction of the components. When components have a strong physical connection, but the functions are relatively independent, a functional-modular product architecture is present. Multifunctional tools typically exhibit this phenomenon. The bottle opener of a Swiss Army knife can be used as a screwdriver at the same time.
