2023 Definition of Extreme Design
Extreme Design - problemsolving based on conceptualizing problems in their ludicrous limit - ie, a design which would obviously outperform, but is usually so simple that it is not considered as people seek more expensive, sophisticated solutions. The challenge is to make the ludicrous solution feasible. When accomplished, the cost is 10x lower, while maintaining OSE Spec.
Mundane Examples
- Geardown of extremely high torque wheel drive (7k lb traction force)- 3D printed wheel. Chain drives wheel near outer diameter. This is all done using chain at $10/ft [1] and motors at $10/hp. 5:1 safety factor for chain. [2]. Even with single chain and 4 wheels - we have 28k lb drawbar bull (coefficient of traction = 1) for $400 in chain, $600 in hydraulic motors, and for Engines, we have $25/hp in increments of 16 hp. 40 of these would be required for 640 hp. Standard bank is 6 of these for around 100 hp, at $2500. 640 hp is $16k.
- Useful logical scale is 1 engine to one hydraulic motor.
For best in class Drawbar Pull.
