To a certain degree, I agree. Once you've identified that there's a minimum radius you can safely take the screen through, the folded profile of the screen is obvious. That you then need a moving support structure behind it to be able to apply pressure to the screen is obvious too.

I don't want to denigrate the obviously detailed design work that went into producing the hinge itself, and those details will have been an absolute nightmare to get right, but I'm also not seeing anything immediately which makes it more than conventional mechanical design.
