The example of the new PSD-30 pressure switch from Wika illustrates the product design cycle, and shows that good design and high functionality need not con- tradict one another; instead, form follows function. EUGENGASSMANN In the German language the word “design” has a fairly narrow meaning: The product must meet the demands of the target application, so the conscious design of the look of things. In exact knowledge of the application and the user environment is vital. English, on the other hand, “design” applies to both functional construction and external appearance. This linguistic separation of external appearance and internal function is that good design is nothing less but the highly formalized, also involves emotions and still present in the minds of many design translation of functional specifications.
