Abstract
The research for significant cost-saving effects that characterize major process to simplify products. This research presents a systematic methodology for product simplicity design through an integration of the Theory of Invention Problem Solving (TRIZ) with Value Engineering. Application of this combined approach is illustrated through case studies of a safety buzzer and a multifunctional climbing stick. The contributions of this research include: 1) Presenting a systematic methodology for product simplicity design through an integration of the Theory of Invention Problem Solving (TRIZ) with Value Engineering, and identifying the simplicity priority with the mathematical method objectively; 2)Establishing a novel Function Statement Form thoroughly describing the relationship of all the system components of each other ; 3) Integrating different sub-systems with familiar attributes as a whole new product effectively for decreasing cost, adding product value, and the future analytical studies of the patent evasion.
