Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If stationary charging systems are used, then charging infrastructure is simple and stable, but vehicle mobility and charging flexibility are limited

Engineering Contradiction:
Improvecharging flexibilityVSAvoidcharging system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The charging system transitions from a static stationary charging station to a dynamic mobile charging vehicle that can move freely. The charging apparatus is mounted on a vehicle platform with wheels, enabling it to relocate to different positions to serve multiple electric vehicles, thereby improving charging flexibility while managing system complexity through modular design.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mobile charging vehicle serves multiple functions: it acts as both a charging station and a mobile platform. The single charging pile can service multiple electric vehicles at different locations, making the system universally applicable to various charging scenarios without requiring multiple fixed stations, thus balancing flexibility and complexity.

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

2Adaptability or versatility

If rechargeable batteries with limited storage capacity are used, then electric vehicles can replace petroleum vehicles, but frequent charging at stationary points is required

Engineering Contradiction:
Improveenergy policy adaptabilityVSAvoidcharging time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The mobile charging vehicle enables preliminary charging actions at the driver's location rather than requiring travel to fixed charging stations. The charging service comes to the vehicle, allowing drivers to charge at convenient times and locations, reducing time loss and improving adaptability to varying energy policies.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The mobile charging vehicle acts as an intermediary between the power grid and electric vehicles. It contains a power converting module that transforms AC power to DC charging power, serving as a mobile power conversion station that bridges the gap between limited battery capacity and charging infrastructure availability.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If petroleum-based vehicles are used, then transportation distance and speed are improved, but pollution and energy consumption increase

Engineering Contradiction:
Improvetransportation efficiencyVSAvoidpollution
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The system replaces petroleum-based mechanical propulsion with electric propulsion. The mobile charging vehicle provides electrical energy to electric vehicles, substituting the internal combustion engine system with an electric motor system, thereby eliminating exhaust emissions and reducing pollution while maintaining transportation productivity.

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

Solution Approach 2:

The power converting module changes the electrical parameters from AC power grid output to DC battery charging requirements. This parameter transformation enables efficient energy transfer while maintaining the environmental benefits of electric vehicles, ensuring high productivity with zero direct emissions.

Inventive Principle:
Principle #35Parameter changes
