Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If wired or wireless stationary charging systems are used, then electric vehicles can be charged at specific locations, but energy degradation occurs and the systems are inconvenient and cumbersome

Engineering Contradiction:

Improveenergy degradationVSAvoidconvenience of charging

Core Design Contradiction:

Loss of energyVSEase of operation

Solution Approach 1:

Instead of charging the vehicle at stationary locations, the patent inverts the approach by generating electricity from the moving vehicle itself through wheel-mounted generators that convert mechanical wheel rotation into electrical energy, eliminating the need for external charging infrastructure and reducing energy loss during transfer

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The vehicle becomes self-sufficient by generating its own electricity through the wheel-mounted generator system, converting its own mechanical motion into electrical energy for charging its battery, thereby eliminating dependence on external stationary charging systems and reducing energy degradation

Inventive Principle:

Principle #25Self-service

2Use of energy by moving object

If wired charging connections are used, then energy can be transferred to the vehicle, but physical connectors and cables are required which are cumbersome

Engineering Contradiction:

Improveenergy transferVSAvoidphysical connectors and cables

Core Design Contradiction:

Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical connector and cable system with an electromagnetic generation system mounted on the vehicle wheels, where generators convert mechanical wheel rotation directly into electrical energy that is fed into the vehicle's battery, eliminating the need for physical plugs and cables

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The wheel-mounted generator system serves multiple functions: it acts as both a propulsion component (utilizing wheel rotation) and an energy generation device, eliminating the need for separate charging infrastructure and reducing system complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Use of energy by moving object

If wireless charging antenna structures are used, then energy can be transferred wirelessly, but antenna structures and wireless field generation are required which increase complexity

Engineering Contradiction:

Improvewireless energy transferVSAvoidantenna structures

Core Design Contradiction:

Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent replaces complex wireless antenna structures with a simpler electromagnetic generation system mounted on the wheels, where generators convert mechanical rotation into electrical energy that is directly transmitted to the battery, achieving wireless-like convenience without the complexity of antenna and electromagnetic field generation systems

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The wheel-mounted generator acts as an intermediary that converts mechanical energy from wheel rotation into electrical energy, serving as a bridge between the vehicle's motion and its energy storage system, thereby eliminating the need for complex direct wireless energy transfer infrastructure

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An apparatus may generate energy in response to a vehicle wheel rotation. The apparatus may include a roller, a shaft, and a generator. The roller may rotate in response to a movement or motion of the wheel and may apply a friction to the wheel to decrease a rotational velocity of the wheel. The shaft may rotate in response to a rotation of the roller. The generator may generate an electrical output based on rotation of the shaft and convey the electrical output to an energy storage device or to a motor of the vehicle.
