Theory of Inventive Problem Solving, or TRIZ, is "the next evolutionary step in creating an organized and systematic approach to problem-solving." In other words, it's a way to get better at solving problems. One of the principles of TRIZ is "Another dimension." This principle suggests that when you're having problems with straight lines, you should try using a second or third dimension. Go upwards, sideways, or around corners. Reflect energy, bend metal, change your route. You can also move dimensions by rotating the object, changing your viewpoint, or even changing the number of objects. By thinking outside the box in this way, you can often find solutions to problems that are more effective than the ones you would find using traditional methods.
