The TRIZ Methodology
The TRIZ Methodology was funded in the 1940's by Genrich Sauowitsch Altshuller. It resulted from the sifting of a large number of patent specifications, from which Altshuller selected those, which seemed to describe a technical break-through. He evaluated these more exactly and recognized three substantial regularities:
- A large number of inventions are based on a comparatively small number of general solution principles.
- Only the overcoming of contradictions makes innovative developments possible.
- The evolution of technical systems follows certain patterns and laws.
With the help of this method inventors try to systemize their activity in order to come faster and more efficiently to new problem solutions. In meantimes the TRIZ method spread world-wide and is "in a flux" (Zobel).
In the englisch linguistic area also the designation TIPS (Theory of Inventive Problem Solving) is common.
TRIZ contains a set of methodical tools, which facilitate it to analyze a given technical problem better and make it possible to find creative solutions. The methods of the classical TRIZ are:
- Innovative principles and contradiction table
- Principles of separation for the solution of physical contradictions
- Algorithm or also step procedure for the solution of inventioning-problems (ARIZ)
- System of 76 standard solutions and material field analysis (SFA, in former times also mentioned as WEPOL-analysis (rus.))
- S-curves and laws of development of systems (evolution laws of technical development, regularities of technical evolution)
- Principal (Law) of Ideatity
- Modelling technical systems with the help of " Small Men" (Dwarf models)
