Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wired or wireless stationary charging systems are used, then energy can be transferred to the vehicle, but the system becomes cumbersome and requires specific locations for charging
Solution Approach 1:
The vehicle serves itself by generating electricity through its own wheel rotation during movement. The generator is directly coupled to the wheel, allowing the vehicle to produce its own energy without external charging infrastructure, thus achieving self-service energy generation while eliminating the need for stationary charging systems
Solution Approach 2:
The invention extracts the energy generation function from external stationary charging systems and relocates it directly to the vehicle's wheel assembly. By integrating the generator with the wheel rotation mechanism, the system removes the dependency on external charging infrastructure and performs energy generation independently within the vehicle itself
2Loss of energy
If wired charging connections are used, then energy can be transferred to the vehicle, but energy transference degradation occurs
Solution Approach 1:
The vehicle generates its own energy through wheel-driven generation, eliminating energy transference losses associated with external charging systems. The generator converts mechanical energy from wheel rotation directly into electrical energy onboard, achieving self-service energy production with no transference degradation
Solution Approach 2:
The invention introduces a direct mechanical-to-electrical energy conversion mechanism (generator coupled to wheel) as an intermediary process. This eliminates the need for chemical energy storage and transfer through batteries during charging, thereby removing the energy losses associated with wired or wireless power transmission to stationary charging systems

AI summary
An energy system can store and provide energy to power a vehicle. The energy system can comprise a generator configured to generate an electrical output, a capacitor configured to receive the electrical output from the generator and store the electrical output as a capacitor energy, a battery configured to receive the capacitor energy from the capacitor, a diode electrically positioned between the capacitor and the battery and configured to convey the capacitor energy from the capacitor to the battery, and a roller configured to contact a wheel of the vehicle and to rotate about an axis in response to a rotation of the wheel to cause the generator to generate the electrical output.
