ABSTRACT
This chapter reviews three examples of the use of design of experiments(DoE) in product design: mechanical one and two electrical ones. DoE can be used in product design in exactly the same way as it is used in process design and improvement. The important design factors are determined and evaluated, and those which produce the lowest-cost, highest quality, and most reliable product are selected. Product design is viewed by many as a discipline where intuition and inspiration are the most valuable commodities, and efforts to systematize and organize these skills are viewed as attempts to stifle creativity. Seven design features were chosen as factors in the fuel rail design using a Taguchi L8 array. DoE in product design is the digital input board, in which the experimenters wanted to set the low and high threshold voltages at levels that would assure no false readings.
