The article presents some of the author's developments in the field of TRIZ - the theory of solving inventive problems. The developments are expected to be turned into an assistant program intended for a wide range of users and a wide range of tasks. A model for setting the problem is proposed, in the form of an extended scenario analysis, then the complexity that hinders the implementation of this scenario is identified, and ways to resolve contradictions are proposed. Basically, the proposed methodology for setting and solving the problem corresponds to the theory developed and developed by G.S. Altshuller and his students. New is a model that unites different “branches” of TRIZ theory and practice.
