Among creative and innovative problem solving algorithms, TRIZ solves difficult problems by finding contradictions of the problems. In TRIZ, there are two types of contradictions. One is a technical contradiction and the other is physial contradiction. A technical contradiction occurs between two desirable functions of a system. We call it a trade-off contradiction. On the other hand, a physical contradiction appears when two opposite properties are required from the same part of a system. In TRIZ, the ARIZ has been developed by Altshuller for reducing trial-and-error while solving problems. It is known as an inventive problem solving. It transforms difficult technical contradictions of a given problem into the corresponding physical contradiction to solve the problem easily. However, ARIZ-85c, the most recent version of the ARIZ, has inefficient and time-consuming features that cause trial-and-errors. In this paper, we propose the Butterfly algorithm based on the Butterfly diagram to reduce trial-and-error features by giving the right solution strategy based on propositional logic when selecting technical contradictions and physical contradictions for a given problem. The Butterfly algorithm can systematically find the solution strategy for the problem, and thus it helps to solve contradictions efficiently.
