Abstract: Aiming at the problem that the existing design reuse was inclined to geometry and topology of product reuse,which could not accomplish the demand-varying design,the method for function reuse and variation of design history based on Function-Effect-Solution (F-E-S) mapping was proposed in response to the local demand-varying.The information model of design history was established by using F-E-S mapping,and the process model of design history's function reuse and variation was constructed by combining with the design requirements of desired product.The local demand-varying design was realized from the perspective of function reuse and variation.The feasibility of proposed method was verified through the example of forklift drive axle.

Key words: function-effect-solution, function reuse, function variation , local demand-varying, product design
