TRIZ is the theory of inventing. It's based on the study of over 3 million patents. One of the TRIZ principles is called "merging". TRIZ suggests that you can often solve a problem by merging two or more objects into one. For example, if you need a light but also need to save battery power, you could merge a flashlight with a solar panel. The solar panel would recharge the flashlight's batteries during the day so that the flashlight would be ready to use at night. This principle can be applied to all sorts of problems, from engineering design to business strategy. So next time you're stuck, try thinking about how you could merge two or more objects to create a solution.
