INNOVATIVE DESIGN FOR PATENT AVOIDANCE OF SLUDGE DRYER BASED ON TRIZ AND DFSS
In order to solve the problem that traditional patent avoidance design lacks a reasonable process of excacating and solving problems,its design scheme may have potential failure modes.Combining TRIZ and Six Sigma design,a new patent avoidance innovative design method was proposed and applied to the patent avoidance innovative design of sludge dryer.Excavate and analyze the target patents,identify the needs,and then determine the direction of circumvention,innovative and optimize the design.The patent of the existing sludge dryer has been successfully evaded and innovated,which makes the innovative sludge dryer have the advantages of high drying efficiency,energy conservation and environmental protection,effective wall adhesion prevention and automatic feeding.The feasibility of the proposed method is verified,which provides a reference for the patent avoidance design of enterprise products.
