The multi-screen approach, structure of the strong spirit1
Altshuller defines the strong spirit as our ability to conceive of non-usual ideas. For him, this corresponds to our ability to be aware that a system (car) breaks down into super-system (traffic, Road…) and subsystem (engine, steering wheel…). Then, for each of these levels, we must consider the lines of evolution that are the past, the present and the future. This gives us the following diagram2 :
Example: Windshield wipers
- Complex Surface
- Manual wiper
- NO nozzle
- No cleaning product
- Motorized Scanning System
- That eliminates water, dirt…
- No wear on the scanning system
- Single Broom
- No support distribution
- Natural rubber
- Advanced Broom
- Variable support driven by speed
- Material, profile and coating
- Support suitable for operation
- No support for judgment
- No contact
One can see a significant evolution in the geometry of windshields making it more complex the function of windshield wipers. The system and subsystem must evolve to follow the evolutions of the super-system.
In particular, the need to work on the ability of the subsystem to apply a constant force over the entire sweep cycle with regard to the evolution of the windshield Shape . The research must therefore be done in a priority way.
