Underlying Method Common to Most Techniques

Brief History of TRIZ•Genrikh Altshuller – 1926 - Uzbekistan (USSR)•First patent in 10th grade•At age 20 he started studying patents and categorized common solutions•Two key discoveries:• Breakthrough invention is the result of overcoming conflicts.• Technical systems evolve toward increasing ideality.

•Proposed to Stalin that he use TRIZ to help the country, which sent him and his colleagues to 25 years in coal mine labor camp above the Arctic Circle.•In prison, he studied and advance the TRIZ concepts.•After 7 years, Stalin died, Altshuller and comrades were released and wrote TRIZ articles.•Altshuller also wrote several popular science fiction novels using TRIZ to help invent futuristic devices.•In 1989 he became president of the International TRIZ Association.•Died in 1998 after writing 20 books and 400 papers.

•The driving function is growth rate (population growth rate, ideas/time, patents/yr, models/yr, etc…)

The S-Curve is summation (integral) of a growth function (MPV, population, indicator).

Conflict Resolution

•Separate Contradictory Demands• Separation in Space - move conflicts apart• Separation in Time - when does it need to be each way• Separation in Relation - which specific aspect is in contradiction• Separation in System Level - consider the whole system

•Satisfy Contradictory Demands - change some parameter(s)•Bypass Contradictory Demands - make the contradiction irrelevant
