Abstract: In order to meet the demand of innovative design for desktop multiplication, an innovative design method integrating TRIZ(the solution theory of invention problem) and Extenics is proposed. Firstly, the contradiction problem in the innovative design is analyzed by using the extenics contradiction method, then the contradictory parameters are standardized, the TRIZ contradiction matrix is searched, the appropriate invention principle is selected to establish the feasible solution, the extenics transformation is implemented, and the innovative design scheme is obtained, according to the superiority evaluation method. Through the combination of crank-slider mechanism and crank-connecting rod mechanism, the contradiction of doubling the desktop area and keeping the desktop shape unchanged is solved. Finally, the specific mechanism design is expanded and analyzed, and the square table design scheme with variable area is established.

Key words: TRIZ, Extenics, variable area square table, integrated innovation, combination mechanism, innovation design
