A knowledge management model for product design process

A tremendous amount of useful information is generated during the process of designing, but often only the final result is recorded. To effectively manage knowledge can help engineers rapidly redesign another similar product by modifying the original design process. This article brings forward a model to manage knowledge generated from the design process. This model supports the reuse of these design process knowledge through mapping the product composition and variation relation in practical product design to the product design process knowledge in effect. This article also gives an example of product design to validate the model
