Abstract: To integrate two single-function products into a multi-function product,a matrix-based conceptual solution generation approach was proposed.The overall function of a product was decomposed into meta-functions,and the meta-functions were represented by the functional basis and divided into three classes of primary function,application function and auxiliary function.The function similarity matrixes were constructed and the filter rules as well as the calculation rules were defined.The total function similarity matrix of two single-function products was acquired by their input-flow similarity matrix,function similarity matrix and output-flow similarity matrix,and it was simplified according to the filter rules.The component-component matrix of the two products was acquired by the calculation of the function-component matrices and their total function similarity matrix.The component correlation relationships were analyzed and the components were respectively removed,modified and reserved according to the correlation index.Consequently,the design solution of a new multi-function product could be obtained.As an example,a new shaver's conceptual solution was acquired under the help of provided approach by analyzing the functions of a shaver and a portable cleaner.
