Here’s some more suggestions:
Design 4 Survival:
As Dieter Rams pointed out. We’d better make our products autonomous since their might be a day where the whole system collapses. Whether this might happen or not doesn’t matter. Must be an interesting exercise.
Dependent User Products
Make a product user-dependent. So the user must ‘care’ for it. Therefore the user will develop a relationship with the product and not cast it away easily/quickly. After Robots by Dune&Raby. A sort of Tamagothi-effect. You don’t change your pet because a new fancier one walks by do you?
The Fun Theory:
