TRIZ

TRIZ (/ˈtriːz/; Russian: теория решения изобретательских задач, romanized: teoriya resheniya izobretatelskikh zadach, lit.

The development and improvement of products and technologies in accordance with TRIZ are guided by the laws of technical systems evolution.

Altshuller began developing TRIZ in 1946 while working in the inventions-inspection department of the Caspian Sea flotilla of the Soviet Navy.

Altshuller realized that a problem requires an inventive solution if there are technical contradictions (improving one parameter negatively affects another).

The arrest was partially triggered by letters he and Raphael Shapiro sent to Stalin, ministers, and newspapers about Soviet government decisions they considered erroneous.

[22][self-published source] It has been used by Leafield Engineering, Smart Stabilizer Systems, and Buro Happold to solve problems and generate new patents.

[23] The automakers Rolls-Royce,[24] Ford, and Daimler-Chrysler, Johnson & Johnson, aeronautics companies Boeing, NASA, technology companies Hewlett-Packard, Motorola, General Electric, Xerox, IBM, LG, Samsung, Intel, Procter & Gamble, Expedia, and Kodak have used TRIZ methods in projects.
