Abstract
Abstract This article presents tools used in the Theory of Inventive Problem Solving (TRIZ) which are useful when assessing the evolution direction of technical systems. The following matters are discussed: the S-shaped curve, laws (trends and lines) of the evolution of technical systems, multi-screen diagrams, as well as analysis of evolutionary potential. Inventive laws formulated by Gienrich Altshuller as well as laws previously formulated by a Polish writer and promoter of knowledge, Aleksander Głowacki, writing under the pen name Bolesław Prus, have been presented. Finally the innovation roadmaps have been shown. The use of individual tools has been supported by practical examples taken from research performed by the authors, and the usefulness of individual methods was evaluated. All methods have been compared and evaluated.
Highlights
TRIZ is the acronym from the Russian Теория Решения Изобретательских Задач, i.e. “Theory of Inventive Problem Solving” and constitutes an extensive methodology for solving complex technical, marketing, and organizational problems
The creator of this methodology is the Russian inventor and engineer, Gienrich Altshuller (1926-1998). When he worked in the Inventions Section of the Caspian Navy, and analysed many patents, which led him to the conclusion that, since technical systems evolve according to certain rules, these rules can be discovered and used to create algorithms for solving inventive tasks [12]
In his work [1], which according to [33] is considered to be the most important of Altshuller's publications, the creator of TRIZ stated that the laws of technical systems' evolution are real, constant, and repetitive relations exist between elements inside the system and those in the external environment
