The eight "lines of evolution" you are describing are the most basic embodiment of the last phase of TRIZ development, beyond the recognition of common and repeatable inventive principles. When the patent literature is studied, we find the same repeated patterns of process and product technology that we find in problem solving principles which were the source of the original TRIZ 40 principles. One of them is the progression of systems to become more dynamic and responsive over time. Another would be the field progression line--mechanical, acoustic, thermal, chemical, electronic, electromagnetic. Think about the progression of communication systems from drum banging to smoke signals to phone to wireless, etc. Think about chemical polymerization from uncontrolled thermal polymerization to sophisticated chemical catalysis to microwave catalysis. Think about food preparation from "beating" to smoking/heating, seasoning, heating, microwaves, etc. These original 8 lines are described by different lingo by different people. Sometimes there is "backfilling" when a line has been "skipped" and may present a unique small volume commercial opportunity (the Motorola "crank" phone, going back to a mechanical field to recharge a cell phone). In my workshops, I use oral care and as another illustration of this particular line.Various consultants and further research has produced claims of several dozen to hundreds of these lines, but in my opinion most of these are dissections of the original eight. There are software products that map these lines and provide illustrations to assist a user, but these are really not necessary in actual practice, I have found.Be glad to answer any questions and discuss how these lines can be used to pro-actively plan product development in a way that is far superior to consumer surveys (if you had asked a user of a stove what they wanted in their next oven, would they have said a microwave when they have no comprehension of the concept?).
