The contradiction matrix is the most popular tool of the Theory of Inventive Problem Solving (TIPS, rus. TRIZ). It consists of 39 engineering parameters and 40 principles. Intersecting a parameter that is improving with one that is deteriorating automatically produces a technical contradiction (TC) that is successfully overcome if an adequate TRIZ principle is used. The same result can be obtained if two parameters are displayed in the space-time (LT) system as units whose multiplication (conjugation) produces the product in the form of a new LT-unit leading to an ideal final solution (IFS) of TC. It was found that 18 of the 39 TRIZ parameters can be represented as basic LT units, while the remaining 21 TRIZ parameters and all 40 TRIZ principles represent complex state expressions. The paper demonstrates the existence of synergies in finding an inventive problem IFS more effectively if both methodologies are used simultaneously.
