Who invented TRIZ?

TRIZ was first proposed by Russian scholar G.S.Altshuller (also translated by Genrich Archischuller) and his colleagues in 1946. At first, 40,000 of the 200,000 patents were taken out as the most effective solutions to various invention problems. From these most effective solutions, they abstract the basic methods of TRIZ to solve invention problems, which can be widely applied to new invention problems and help people get the most effective solutions of these invention problems. At present, more than 2.5 million outstanding patents have been studied internationally, which greatly enriched the theory and method system of TRIZ. Some companies have established computer-aided innovation systems based on TRIZ and patent database, which makes the automation of invention and innovation dawn. However, TRIZ is more of an idea or method, and people should master it through a lot of practice. Computers can't completely replace the role of people. Alikh Schulier began to establish TRIZ theory in 1946, and one of the important theories is the evolution theory of technological system. There are eight evolutionary rules in this theory, which can be used to solve difficult problems, predict technical systems and generate and strengthen creative problem-solving tools. These eight laws are: 1) the evolution law of S-curve of technical system; 2) Perfecting the ideal degree rule; 3) the law of unbalanced evolution of subsystems; 4) Evolution law of dynamics and controllability; 5) the rule of increasing the integral first and then simplifying it; 6) Evolution law of subsystem coordination; 7) Laws applied to micro-level and growth field; 8) The evolutionary law of reducing human intervention.
