Abstract: In view of the problem that the indoor dust content is too high due to the use of chalk in the traditional face-to-face classroom, Extenics and computer aided innovation technology based on the theory of the solution of inventive problems (TRIZ) are used to innovate the existing dust-free blackboard products. Searching and selecting the dust-free blackboard patent as the research object, using the patent evasion module of computer-aided Innovation Software goldfire to complete the function analysis, a function model is established, the problem function in the model judged, and the function information expressed with the extension basic element model. After determining the circumvention path and using the extension transformation method to evade the replace components, the circumvention model is obtained. Combined with TRIZ solution tool and the divergence tree, the solution is obtained and its feasibility judged. The application of this process can provide reference for other products to design around patent.

Key words: dust-free blackboard, computer aided innovation, TRIZ, theory of the solution of inventive problems, Extenics
