Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If conventional power sources (motors, engines, battery systems) are used in wheeled vehicles, then power can be provided to on-board systems, but the vehicle becomes heavy, noisy, and requires frequent refueling or recharging

Engineering Contradiction:
Improvepower provision to on-board systemsVSAvoidvehicle weight
Core Design Contradiction:
Use of energy by moving objectVSWeight of moving object

Solution Approach 1:

The system harvests kinetic energy from the wheel's rotation during normal operation to generate electrical power, making the vehicle self-sufficient for powering on-board systems without external fuel sources or heavy batteries. The generator converts mechanical rotational energy directly into electrical energy during wheel rotation, and the capacitor stores this energy for later use when the wheel is stationary.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention replaces conventional mechanical power sources (motors, engines) with an electromagnetic energy conversion system. The generator uses electromagnetic induction to convert mechanical rotation into electrical power, eliminating the need for combustion engines or electric motors that require external power sources.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Use of energy by moving object

If conventional power sources are used in wheeled vehicles, then power can be provided to on-board systems, but the system becomes noisy and unsuitable for indoor use

Engineering Contradiction:
Improvepower provision to on-board systemsVSAvoidnoise
Core Design Contradiction:
Use of energy by moving objectVSObject-generated harmful factors

Solution Approach 1:

The system uses the wheel's own motion to generate power, eliminating the need for noisy motors or engines. The generator produces electricity silently through electromagnetic induction during wheel rotation, and the capacitor maintains power supply during stationary periods without requiring any active components.

Inventive Principle:
Principle #25Self-service

3Duration of action of moving object

If battery systems are used to power wheeled vehicles, then continuous power can be provided, but the batteries require frequent recharging or replacement

Engineering Contradiction:
Improvecontinuous power provisionVSAvoidtime for recharging or replacement
Core Design Contradiction:
Duration of action of moving objectVSLoss of time

Solution Approach 1:

The system continuously harvests energy during wheel rotation and stores it in the capacitor, ensuring uninterrupted power supply. The capacitor maintains electrical charge during stationary periods, and the generator automatically recharges it during motion, creating a continuous power cycle without interruption or maintenance.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system automatically recharges the capacitor during wheel rotation without user intervention. The generator continuously converts mechanical energy to electrical energy, and the capacitor self-regulates its charge level, eliminating the need for external recharging infrastructure or battery replacement.

Inventive Principle:
Principle #25Self-service

4Use of energy by moving object

If solar cells are used to power wheeled vehicles, then power can be provided, but insufficient power is available indoors or at night

Engineering Contradiction:
Improvepower provision to on-board systemsVSAvoidpower availability
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The system dynamically adapts to different operating conditions by harvesting energy during wheel rotation regardless of location or time of day. Unlike solar cells that depend on external light conditions, the generator produces power whenever the wheel rotates, providing reliable power availability in all environments including indoors and at night.

Inventive Principle:
Principle #15Dynamics
