The application on engineering and technology problems with computeraided innovation software Pro/Innovator based on TRIZ was studied. Aiming at the current problem that the hand device of track inspection car can not be commutated conveniently, which lead to the inefficiency of operating, TRIZ and computeraided innovation software Pro/Innovator were applied to find where conflicts exist through system components' functional and causal analyze. Combined with the innovative solutions Library the software provided, and according to the corresponding innovation principles, the solution of the problem was presented. The results show that the working efficiency is improved and the function of convenient commutation is achieved after improve the reversing device.
