Patents are an overlooked tool in inventing and problem solving.
A colleague and I were discussing the challenge of inflating tires to an optimal pressure. He is an avid Off road driver and was thinking of ways to ensure his tire pressure matches the road ( or dirt or quick sand ) conditions.
In trucks, a central compressor pumps air through a tube system, slip ring and into the wheel. This system is cumbersome and expensive for the average off road vehicle or even your suburban SUV. He was thinking of a compressor fitted on the wheel and we were discussing power requirements, battery considerations and prototyping routes.
I always start my inventing journey with looking at what’s been done. A quick search identified
https://patents.google.com/patent/US5975174A/en
and then searching the patents citing it found some additional concepts.

More importantly, the identified patents help refine the terminology used by people in the field. Now a google search found a company with a product
and related patents

Reading through these, you realize the clever way they use the wheel rotation and weighted item to create a peristaltic pump. Using TRIZ principles raises the question can we do with less ? The simple answer : use the car weight.
The tube should be fitted in the tire so the car weight compresses the tube along its length, generating the pressure to pump the tire. Now that there is a concise description of the invention its useful to go back to a patent and general search. Very few things are really new and indeed the concept has already been conceived by http://www.selfinflatingtire.com
While the dream of striking it rich with a novel way of maintaining tire pressure is replaced by practical business thoughts. The process leading to the solution highlights the interplay between inventive tools and search. Using search to identify methods of solving problems, makes methods like TRIZ extremely effective for individuals or teams.
