Abstract: To satisfy the requirement of patent design around,the design constraint conditions were analyzed by taking mechanical products as the example,the patent rights scope figure of products was proposed and the around route muster based on function tailor was established.From the present technological view,the central patent identification of products and competitors'four dimensionalities patent portfolios were elaborated to build strategies of patent around.Based on analytical and solution tools of TRIZ,the corresponding solution methods aiming at different problems were proposed,and the around design projects were obtained.To guarantee the success of patent around,the projects were evaluated by system constraints.The example patent of mechanical product was chosen as target to design around,and the proposed patent technologies and the patent system constraints were verified reliably and effectively.

Key words: inventive problem, invention problem solution theory, patent design around, technical constraints, system constraints
