Exploration and Application of the Operator STFC Based on the Operator STC

Abstract

The operator STC (Size-Time-Cost), as a kind of innovative thinking method in the TRIZ (Theory of Inventive Problem Solving), conducts extreme thinking regularly from three dimensions, namely size, time and cost, so as to find a solution to the problems. In order to expand the dimension of analysis and problem solving, an operator STFC (Size-Time- Degree of freedom- Cost) is constructed in this paper based on the operator STC, and the degree of freedom (F) dimension is added to make the operator STC theory more complete. At the same time, the process and application steps of the operator STFC are given to solve problems, meanwhile the application of the operator STFC in technical and non-technical fields is discussed with examples, which provides application steps and case reference.
