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. “40 Inventive Principles” “Conflict Resolution” “Technology Trends”

40 Inventive Principles Print them out & keep them handy. We use some naturally. Contradiction Matrix – not necessary (suggests principle based on type of conflict)

Algorithm of Using 76 Standard Inventive Solutions for Inventive Problem Solving (AIST) Construct the model of the problem according to ARIZ group 4.1 Measuring Transform the model of the problem into a Su-Field No Can measuring be substituted for detecting? Harmful interactions Measuring or modification? No Yes 1.2.1, 1.2.2, 1.2.4, 1.2.5, group 5.1, 5.2, 5.3 No Is Su-Field complete? Can substances and fields be introduced? Yes Can substances and fields be introduced? Can substances and fields be introduced? Any harmful interactions? double, chain Su-Field Is the introduction of a magnetic field possible? group 2.1 Is the formation of complex Su-Fields admissible? 2.4.1, 4.4.1 Can ferromag. subst. and mag. fields be introduced INSTEAD of those which are avail. in the Su-Field? Yes No Check for the presence of ferromagnetic substances in the Su-Field M.A,T,Ch.E.M. 2.2.1 Is the substitution of the field admissible? No 2.4.2-2.4.4, 2.4.7, 2.4.8, 4.4.2 2.4.5, 4.4.3 No Can additives be introduced to the external environment? Yes 2.2.2-2.2.4 Check if the Fe-Field system is dynamic Is the system dynamic? Yes No 2.2.5, 2.2.6, 4.3.1, group 5.3, 5.4 Yes 2.4.9 2.4.6, 4.4.4 Can ferromag. additives be introduced to the external environment? Check if the structures of the Fe-Field components are coordinated Are the Su-Field components coordinate? Yes No 2.4.10, 4.4.5, group 5.3, 5.4 Yes 2.3.1-2.3.3, 4.3.2, 4.3.3 Can electric fields and electric currents be used? Check if the dynamics of the Fe-Field components are coordinated Are the dynamics of the Su-Field components coordinated? 2.4.11, 2.4.12 Yes No Yes Apply 3rd Class Standards to solve the problem Note: The numbers outside of the blue boxes indicate the Standard Inventive Solutions that are used.

“Transition Function” in Math – derivative or integral S-Curve Analysis “Transition Function” in Math – derivative or integral The S-Curve is summation (integral) of a growth function (MPV, population, indicator). MPV or Accumulation Time The driving function is growth rate (population growth rate, ideas/time, patents/yr, models/yr, etc…) Rate of Growth Time

Conflict Resolution Use the 40 Inventive Principles 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
