Technology often conflicts with environment. Design engineers always make efforts to obtain the balance between technical innovation and environmental protection despite full of hard tasks. This paper presents the conflict-problem-solving CAD software, Eco-Design Tool, which integrates TRIZ into the eco-innovation idea. Design engineers can acquire the most feasible solution and inspiration through the proposed software. Eco-Design Tool possesses five major functions: eco-design targets search by the analytic hierarchy process technique, product evaluation, TRIZ engineering parameter recommendation reflecting eco-efficiency elements, TRIZ inventive principle exploration by the statistic technology, and TRIZ inventive principle interpretation. Successful product examples have demonstrated the applicability of 'Eco-Design Tool'.
