TRIZ theory suggests that sometimes the best way to solve a problem is to remove the problem entirely. This principle is known as inert environment, and it posits that by removing oxygen and other reactive agents from the equation, you can prevent your device from breaking down. This principle is employed in light bulb design, where bulbs are partially evacuated and filled with inert gases to prevent the thin filament from oxidising. In other words, sometimes the best way to solve a problem is to take away the things that cause the problem in the first place. So next time you're facing a difficult problem, ask yourself: what would happen if I just removed the key players? It just might be the solution you're looking for.
