In my opinion. Those who setup rules for inventions have not understood. Like in fusion or battery development. Setting up simple rules that everybody needs to follow just will just result in incremental progress.
We need groundbreaking inventions. One way to figure out those is to look a the man made ”rules” of the innovative process.
Here you just set generate new questions to the rules. Questions are like finding errors in the rule assumption.
So for a battery. A non moving part battery is more safe and can be placed in a phone. But that does not mean its the best for a car. I mean the car is big enough for a moving part car engine. So why not a moving part battery.
So the aim of a groundbreaking invention is probably to invent a ”moving parts battery machine” for vehicles.
