Lines of Evolution
Altshuller established eight Patterns, or Lines, of Technical Systems Evolution:
Here is an explanation of some of these patterns and a few examples of them:
The Pattern of Dynamization suggests that any technical system during its evolutionary process makes a transition from a rigid to a flexible structure. This transition can be summarized as follows: A solid system obtains one joint, then many joints, then the whole system becomes completely flexible. Dynamization also means that a ridged system may be divided into elements that can become moveable relative to each other.
