Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a conventional wind power generating device is installed in a vehicle, then it can generate electricity when wind speed is high, but it is unable to generate electricity when wind speed is low or the vehicle is stopped

Engineering Contradiction:
Improveelectricity generation capabilityVSAvoidcontinuous electricity supply reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The magnetic elements and ball chambers are pre-configured to create magnetic repulsion forces that automatically engage when the fan blade rotation slows down or stops, providing preliminary assistance before complete stagnation occurs, ensuring continuous rotation and electricity generation

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Magnetic fields serve as an intermediary force between the stationary magnetic elements and the moving balls, enabling non-contact force transmission that maintains rotation without mechanical friction, allowing the system to bridge the gap between wind-driven motion and generator rotation

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If magnetic elements and ball chambers are added to assist rotation at low wind speeds, then electricity generation can be maintained during vehicle stops, but the device complexity increases

Engineering Contradiction:
Improvecontinuous electricity supply reliabilityVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The magnetic elements serve multiple functions: they create repulsion forces to maintain rotation at low speeds, provide non-contact bearing support through magnetic levitation, and eliminate the need for traditional mechanical bearings, reducing overall system complexity despite adding magnetic components

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent replaces traditional mechanical bearings and friction-based rotation support with a magnetic field-based system, eliminating mechanical contact and friction, thereby reducing wear and maintenance while maintaining rotational assistance through non-contact magnetic forces

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