Product innovation design based on the theory of TRIZ and functional analysis

Functional analysis,ideal final result and S-Field analysis method are introduced.The process of product innovation design based on the theory of TRIZ and functional analysis is proposed.This process divides product innovation design into several stages:producting function analysis,abstracting ideal solution,establishing system S-Field model and sloving the problem functional model,which instructs the designer to start from the product function and rapidly realize the product innovation design.Reciprocating sealing of hydraulic cylinder is taked as an example to illustrate the effectiveness of the process.
