Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional onboard charging systems use fuel-based generators, then power can be generated onboard, but fuel emissions are produced which are harmful to users and the environment
Solution Approach 1:
The patent replaces the fuel-based mechanical generator system with an electromagnetic generator system that converts wheel rotation directly into electrical energy. This substitution eliminates combustion processes and fuel emissions while maintaining onboard power generation capability, resolving the contradiction between energy self-sufficiency and environmental harm.
Solution Approach 2:
The patent converts the previously harmful waste energy (wheel rotation that does not contribute to propulsion) into beneficial electrical energy for charging the battery. By capturing and utilizing the kinetic energy already present in the moving vehicle, the system transforms a source of energy loss into a useful resource, eliminating emissions while providing power.
2Duration of action of moving object
If electric vehicles rely on stationary charging stations, then batteries can be recharged, but charging infrastructure is limited and causes range anxiety
Solution Approach 1:
The patent enables the electric vehicle to charge itself during operation through the onboard generator system. The vehicle becomes self-sufficient by generating its own charging power from its motion, eliminating dependence on external charging infrastructure. This self-service capability dramatically increases charging availability while extending effective range.
Solution Approach 2:
The patent enables continuous charging during vehicle operation rather than requiring periodic stops at charging stations. The generator operates continuously as long as the vehicle is moving, providing uninterrupted energy replenishment that extends range and eliminates range anxiety associated with limited charging infrastructure.
3Duration of action of moving object
If electric vehicles have larger batteries for extended range, then mileage between charges increases, but vehicle weight increases
Solution Approach 1:
The patent enables continuous energy replenishment during vehicle operation through the onboard generator. This continuous charging capability allows the use of smaller batteries that are charged progressively during driving, rather than requiring large batteries to store all necessary energy in advance. The generator acts as a continuous power source that offsets battery consumption in real-time.
Solution Approach 2:
The patent transforms the static battery capacity problem into a dynamic energy management system. Instead of relying solely on fixed battery size to determine range, the system dynamically generates additional power during operation based on vehicle motion. This dynamic approach allows flexible range extension without proportionally increasing battery weight.
