Pattern 3: Multiplication
If one is good, two is better. It’s not always true, but as a technique for innovation, it certainly fits the bill.
With the Multiplication Technique, a component has been copied but changed in some way, usually in a way that initially seemed unnecessary or odd.
For instance, children’s bicycles have regular wheels plus two smaller “training wheels” attached to the rear wheel to keep the bicycle steady while the child learns how to ride. The two wheels were multiplied (and changed slightly) to create a new product that appeals to a different audience.
