40 Principles of Invention
Encyclopedia
The "forty principles" of TRIZ are basic engineering parameter
s of common objects, such as weight, length, and manufacturing tolerances. TRIZ
methodology claims that by studying an individual parameter which is causing a problem (e.g., the weight of an object needs to be reduced), and the other parameters which are in conflict with it (e.g., lower weight would require thinner material, which is more likely to undergo catastrophic failure if overstressed), engineering solutions can be created for invention problems.
Parameter
Parameter from Ancient Greek παρά also “para” meaning “beside, subsidiary” and μέτρον also “metron” meaning “measure”, can be interpreted in mathematics, logic, linguistics, environmental science and other disciplines....

TRIZ
TRIZ is "a problem-solving, analysis and forecasting tool derived from the study of patterns of invention in the global patent literature". It was developed by the Soviet inventor and science fiction author Genrich Altshuller and his colleagues, beginning in 1946...
