Traditionally, the TRIZ contradiction table has been used to compare a desired “improving” feature” against a “gets worse” feature, optimizing the choice of which of the TRIZ 40 principles should be first used in attempting a solution to resolve the contradiction. Despite numerous advances in TRIZ problem solving tools and methodologies, the use of this process in reverse to determine the linkage between observed problem solving behavior and the underlying contradictions remains undeveloped. This type of analysis could be useful in analyzing competitive business strategies or in the analysis of criminal activities. This paper explores the use of the principles in reverse logic and offers a helpful methodology that can facilitate investigative and analytical research across many fields. The researcher or research group first determines the potential observed or hypothesized principle at work in an imminent organizational development, technical innovation, or behavior shift. In the next step, the research determines the underlying contradiction or contradictions which may be resolved by the principle at work. Through investigating the use of principles in reverse, competitor or criminal actions and innovations can be anticipated, analyzed, and pre-empted. Alternatively, the behavior or developments of neutral subjects may be further understood. In addition to expanding the use of TRIZ, the methodology illustrates that the classic 40 Inventive Principles and the Contradiction Matrix still continue to present innovative applications.

A tool to estimate the strength and life of a Patent

TRIZ (Theory of Inventive Problem Solving) classifies inventions into five novelty levels. At level 1 are slight modifications of the existing systems.  At level 2 are those inventions that resolve a system conflict or contradiction using usually inventive solution or inventive principle used to solve similar problems in other systems.    At level 3, the inventions change one subsystem or resolve the system conflicts in a fundamental way. At level 4, the invention gives birth to new systems using interdisciplinary approaches. The level 5 inventions are closer to a recently discovered scientific phenomenon. See article for a complete discussion.

Alexander Selyutsky - a key figure in the history of TRIZ!

Alexander Selyutsky

Selyutsky Alexander Borisovich was born April 6, 1933 to an intelligent Jewish family residing in Leningrad. During the World War II the plant where his father was working was evacuated to the Urals, and the family (the parents and Alexander) moved to Chelyabinsk. Here, Alexander graduated from high school. He wanted to go to a military school, but didn’t pass vision test and entered the Chelyabinsk Polytechnic Institute. In his first year he was forced to learn boxing (because of frequent anti-Semitic attacks) and became a Komsomol activist.

After graduation, he was sent to Petrozavodsk Onega tractor plant, where he worked as a designer. He continued leading a very active social life, organized and led voluntary militia patrolling the streets of the city because the situation was very criminal. In the search for more satisfying work he became interested in patenting, completed appropriate courses and became a patent agent.

In 1960, Alexander married Dolly Naumovna Audleys, and had a daughter Alla in 1961. The same year G.S Altshuller published a book " “Learn how to invent"[1] . After reading this book in 1965 Selyutsky wrote a letter to Altshuller. This letter started their acquaintance by correspondence. Since then, Alexander became one of the most dedicated Altshuller’s disciples and an active promoter of the emerging new science.

They finally met in 1968 in Dzintary (near Riga), at the seminar organized by the Central Board of VOIR (state leading inventors’ and innovators’ society) that invited Altshuller and several of his associates. It was the first time that Alexander and others got a chance to work under the direct guidance of Altshuller and to learn from him. Later, in 1983, Alexander participated as one of the instructors in the seminar conducted by G.S. Altshuller in Moscow at the Institute for continuous education for chemical and petroleum industries.
