The method is based on the idea of finding new ideas and approaches to a given problem for two seemingly completely different, contradictory variables. This works especially well when dealing with technical inconsistencies in products. For example, you can think about how to make a car go faster even though it’s getting heavier.
This means that factor A must always be considered in direct connection with factor B. The method is particularly popular with scientists, engineers and technicians because, on the one hand, it can be solved very systematically and, on the other hand, the resulting technical dependencies ideally trigger these groups of people and motivate them to find solutions.
