Solving, TRIZ is its Russian acronym), which is a systematic methodology system summarized by the research team headed by the inventor Archischuler of the former Soviet Union through analyzing and refining 2.5 million high-level invention patents, to guide people to innovate and solve engineering problems.
TRIZ theory is guided by dialectics, system theory and epistemology, based on the research results of natural science, system science and thinking science, and based on the evolution law of technological system, including basic concepts such as technological system and technological process, contradiction (arising from the evolution process of technological system), resources (used to solve contradictions) and idealization (the evolution direction of technological system). TRIZ theory provides methods to analyze engineering problems, including contradiction analysis, function analysis, resource analysis and material field analysis, and also provides corresponding problem-solving tools, including technical contradiction innovation principle, physical contradiction separation principle, scientific principle knowledge base and standard solution of invention problems. TRIZ theory provides a creative problem solving algorithm (ARIZ) for solving complex problems. At the same time, TRIZ theory also includes some innovative thinking methods, such as nine-screen method, intelligent villain method, goldfish method and so on.
