Patterns of Evolution
Technological systems evolve according to
certain statistically-proven patterns. These patterns - called the Patterns of Evolution - form
the common threads between evolving systems, as revealed through patents and other sources
describing technological achievement. The Patterns of Evolution constitute much of the
theoretical base of the I-TRIZ methodology.
Traditionally, system evolution proceeds through trial and error. Most trials fail, however,
because they are influenced by psychological inertia. With I-TRIZ, the majority of trials are
productive because they follow the Patterns of Evolution, eliminating the need for numerous
blind trials.
And because the Patterns of Evolution represent strong, historically-recurring tendencies,
they can also be used to predict the future evolution of a system. |
