The three separation principles that Altshuller discovered were separation in time, in space, and in phase of matter. The latter can be easily generalized into separation in state of object.
The state need not be phase of object's matter. It can be something else, for example, moving state and resting state, the state of transition and the stationary state, etc. Separating contradictory requirements (such as object has to have property P and has to not have it) in these states would result in the following solution: when object moves it has property P, but when it rests, it has not. There are myriads of other possible states suitable for separation.
For processes states are usually stages. Thus, we arrive at separation in stages. But processes may also have states, which are not stages. For example, flow may have laminar state and turbulent state. There could be separation between these states: when flow is laminar X takes place, otherwise does not.
Recently while searching on the internet I came across a funny interpretation of separation in state:
I was curious where from could Peter Hanik, the author of the above passage, get such strange ideas. He was referred to as President of Pretium Innovation LLC. Search on the internet revealed that Pretium Innovation is a partner of Ideation International. Hence, the above ideas were probably taught to him by Ideation. Funny concepts Ideation spreads around, ought to be said.
