This paper describes an innovative design thinking process with simplified TRIZ that can be used to resolve contradictions in all domains with words such as “dilemma”, “conflict”, “contradiction” and “paradox”. The design thinking process that have been used at d.school at Stanford and Potsdam University are popular as a human-centered innovation process with “Empathy” and “Define” stages for human-centered problem finding. However, many results may be not innovative because it uses mostly “Group brainstorming” at “Ideate” stage.TRIZ users have complained that the Russian conventional TRIZ is so difficult to learn and apply. They consider that it is useful in manufacturing and mechanical fields mostly. This paper suggests an innovative design thinking process with simplified and generally usable the step-by-step TRIZ. Its effectiveness of the innovative design thinking process with the simplified and step-by-step general TRIZ is explained in the development case study, a smart wind free air conditioner.
