Systematic Inventive Thinking Method Based on Theory of Constraints

This paper aims to develop an effective and widely applicable creative design method. First, the relationships of integration between systematic inventive thinking (SIT) and theory of constraints (TOC) were analyzed. According to the analysis, a new model of SIT based on TOC was constructed. Next, the detailed creative design steps of this method were explained and a strategy to upgrade an old system or develop new systems based on an existing one was proposed in terms of this creative method. Then, an example was demonstrated to validate the method. This proposed creative design method is different from conventional approaches, which uses the elements in the design environment, and introduction of new element is avoided.
