An essential reference work with valuable practical knowledge for designers and product developers. At the beginning of every product development lies an idea or a customer request. During the subsequent stages of conceptualization, design, and elaboration, designers face numerous decisions that determine all aspects of a product, from functionality to cost. Thus, every designer navigates a complex process, resulting in their preferred solution amidst many options. This handbook, now in its second edition, comprehensively supports designers in all their tasks and decisions. The following topics await you: Part I (Fundamentals) presents a compilation of materials, elements, and properties that play a role in technical products. Part II (Developing and Designing) addresses how even higher requirements can be implemented.
