The "inch power" can be seen in Taiji Ji, An, vital punch, brush knee, ... The interest question is "Is inch power used for striking or throwing?" Do your want to kill your opponent with your Taiji "push"?, or you just want to use your Taiji "push" to throw your opponent down, and let the hard ground to do the striking for you?
When we mix the "striking world" and the "throwing world", thing can get confused. In the
- striking world, you want to create a "head on collusion" so you can use your your power and hurt your opponent to the maximum.
- throwing world, you want to create a "rear end collusion" so you can add your force along with your opponent's force and that will make your throw easier.
Do you need to break your opponent's structure before knocking him out? I think that will be counter productive to a "head on collusion". The better structure that your opponent has, the more damage that when he receives your punch. Here is my favor "head on collusion" example. Please watch how did Anthony Hopkins killed that bear.

Do you need to break your opponent's structure before throw him down? I think that will also be counter productive to a "rear end collusion". All you need is just give your force first, when your opponent resists, you borrow his force and "reverse" your throw. There is rarely a shock first, it is usually a "everything is fine...what the hell?" kind of feeling.
