Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If the power of power supply units is increased to reduce recharge time, then recharge time is reduced, but cable and battery heating increases causing premature degradation and higher costs

Engineering Contradiction:

Improverecharge timeVSAvoidbattery heating and degradation

Core Design Contradiction:

Loss of timeVSObject-affected harmful factors

Solution Approach 1:

The battery is divided into multiple independent modules that can be recharged separately. This allows the recharge current to be distributed across multiple modules, reducing the heating effect on each individual module while maintaining fast overall recharge capability. The modular architecture enables parallel charging without concentrating excessive power in a single charging path.

Inventive Principle:

Principle #1Segmentation

2Duration of action of moving object

If the battery capacity is increased to improve EV autonomy, then autonomy is improved, but recharge time increases

Engineering Contradiction:

ImproveEV autonomyVSAvoidrecharge time

Core Design Contradiction:

Duration of action of moving objectVSLoss of time

Solution Approach 1:

The large-capacity battery is segmented into multiple smaller modules. Each module can be charged independently and in parallel, allowing the system to maintain large total capacity for extended autonomy while enabling fast recharge by simultaneously charging multiple modules. The modular design decouples the relationship between total capacity and recharge time.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The modular battery system enables continuous charging operation by allowing multiple modules to be charged simultaneously in parallel. This maintains continuous energy input to the battery system without interruption, achieving fast recharge of large-capacity batteries by distributing the charging load across multiple independent charging paths.

Inventive Principle:

Principle #20Continuity of useful action

3Reliability

If manual intervention is required for battery connection during recharging, then connection reliability is improved, but operation complexity and time increase

Engineering Contradiction:

Improveconnection reliabilityVSAvoidrecharge operation simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The recharge system incorporates automatic connection mechanisms where the battery modules autonomously establish electrical contact with the charging station. The modular design includes self-aligning connectors and automatic engagement features that eliminate the need for manual intervention, ensuring reliable connections through precision-engineered self-service interfaces.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Manual mechanical connection operations are replaced with automated systems including robotic arms, magnetic connectors, or electro-mechanical engagement mechanisms. These automated systems provide more consistent and reliable connections than manual operations while reducing operational complexity and time requirements.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Ease of manufacture

If charging stations are placed in non-strategic locations, then installation cost is reduced, but EV usability for long-distance travel decreases

Engineering Contradiction:

Improvecharging station installation costVSAvoidEV long-distance travel capability

Core Design Contradiction:

Solution Approach 1:

The modular battery system enables charging stations to be deployed in various locations and configurations to serve multiple functions. The standardized modules can be adapted to different site requirements, allowing strategic placement along highways, in urban areas, and in remote locations while maintaining cost-effectiveness through modular scalability and multi-purpose deployment options.

Inventive Principle:

AI summary

An automated method is disclosed for recharging Efficient Electric Vehicles (EEVs) without manual intervention. The system identifies the vehicle's presence and determines the position of a recharge inlet—whether single or multiple—using sensors and control algorithms. A robot charger aligns and connects the vehicle to a recharge station, establishing an electrical connection securely and efficiently. The method accommodates various inlet locations and vehicle orientations. Authentication, temperature monitoring, and data exchange between the vehicle and station can be integrated. This invention significantly reduces user involvement and improves recharging speed and reliability. It is suitable for domestic use, commercial fleets, and autonomous vehicle systems, and can be embedded into smart energy management platforms.
