摘要：Product innovation can be achieved by analyzing leading products patents in the *** methods have been proposed for design around patent,commonly using the elimination or replacement of a single patent element However,the existing research fails to restore the position and function of the design around object in the original patent portfolio of enterprises,which often leads to the phenomenon of evading one patent and violating *** paper proposes a method for design around patent through using the fusion of technologies of the evolution theory and bundle-type patent portfolio analysis in the initial stage of product *** object system is analyzed to select technical opportunities through the evolutionary path of technologies and functional trimming methods to achieve circumvent barriers of bundle-type *** bundle patent portfolio is analyzed for the product evolution with a radar *** technological evolution path is combined with the TRIZ innovation method to identify and solve the design *** of the new design is evaluated using the patent system rules for innovative scheme difference from the original patent *** method is verified in a case study for the design of a glass-wiping *** design solution has been patented.
