Trends of Technical Evolution is a tool that is easy to grasp, and to apply to everyday life. The idea of this tool is that all products will follow a set of steps in their evolution, which allows us to decide where the product is now and how it will develop in the future.
A UK based designer Kyle Bean has produced a wonderful example of this, with a nested doll (TRIZ Inventive Principle 7) of mobile phones. From the first Motorola DynaTAC from 1983, to the iPhone, the models fit inside each other to create a visual history of the mobile phone.
