You should do a video on the Theory of Inventive problem solving. A Russian engineer spent his entire life studying patents to see how humans made solutions to stuff like this. It's now generalized into a few charts, and is really quite handy.,(reply>), @Luke Moran TRIZ,(reply>), @John Jennings damn coming back to this video 5 years after is something isn't it and its cool to see you doing well after 5 years too.,(reply>), @lipoff that's the one! I was trained up on it a few decades ago, as an aerospace engineer. Warning though: your mileage will vary!,(reply>), It's called TRIZ.  A simplified version called SIT (Systematic Inventive Thinking) is summarized beautifully in the book Inside the Box by Boyd and Goldenberg.,(reply>), Good thing modern Russians haven’t heard of it ;)
