Innovation design of existing product based on function recombination

The customers' need promotes the innovation of products, function innovation essentially, so analyzing functions of product first and recombining them can help us design new products. Axiomatic design theory provides a method for the design of products, it makes it possible to design structure and decompose function at the same time. This paper proposes one method that improves existing products based on axiomatic design, and takes bicycle for example, verifies the feasibility of this method in detail.
