  Origin of TRIZ

TRIZ is the internationally acknowledged Russian abbreviation for "Teorija Resenija Isobretatelskih Zadac", which can be translated as the Theory of Inventive Problem Solving, also shortened to TIPS.

TRIZ was developed between 1960 and 1980 by the Russian scientist Genrich Altshuller (1926-1998) and his staff (first publication in 1956). In contrast to the common "trial and error" problem solving methods such as brainstorming, synectics, morphological analysis etc, TRIZ only relies on the unbiased laws of evolution of technical systems and therefore enables a focussed search for possible solutions. The discovery and structuring of these laws, as well as other TRIZ components, has been the result of the study and analysis of globally available patents over a period of several decades

TRIZ is regarded today as the most comprehensive, systematically organized invention knowledge and creative thinking methodology known to man. TRIZ has the following advantages over traditional innovation supporting methods:
Marked increase in creative productivity.
Rapid acceleration in the search for inventive and innovative solutions.
Scientifically founded approach to the forecasting of the evolution of technological systems, products and processes.


  The TRIZ Concept

What TRIZ essentially does is identify, exaggerate and eliminate technical and physical contradictions in technical systems and processes instead of trying to find a "half-hearted" compromise. The term "technical contradiction" (TC) - is the key to the TRIZ concept. A TC represents two contradictory properties of a technical system: improving one part or property of a machine (e.g. engine power) automatically changes another property for the worse (e.g. weight or fuel consumption). According to TRIZ, a problem is solved only if a TC is recognized and eliminated. So-called 'habitual blindness', psychological inertia and the all too common tendency to make compromises are all overcome in a logical way. Not only is the scope of the search considerably reduced in size even in the most difficult of cases, TRIZ also opens up completely new ways of thinking.


  TRIZ Components

The most important components in classical TRIZ can be summarised in the table below with regard to the different ways of solving technical problems. The simpler methods, for example, the 40 inventive principles, can be integrated more easily as problem-solving tools but have some restrictions as to their efficiency in solving complex problems.

The most important components of classical TRIZ include the following:

40 Inventive Principles for eliminating technical contradictions. The system of their application in the form of the Contradictions Table.
System of 76 Standards for solving technical problems and substance-field analysis of technical systems.
Step-by-step techniques or algorithms for inventive problem solving (abbr.: ARIZ). A universal tool for solving all kinds of problems.
Double innovation principles for solving non-technical problems.
Separation principles for eliminating physical contradictions.
Methods for analysing system resources.
Database of physical, chemical, geometrical and other effects and their technical applications.
Methods to increase creative thinking, to reduce psychological inertia: operator DTC (dimensions-time-cost), "Little People" visual modelling etc.
Method of anticipatory failure identification (AFI) in technical systems for analysis and prediction of possible sources of failures.
Patterns of evolution of technical systems (TS) for prediction of the development of technical systems, and creation of patent fences.
