Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If public EV charging infrastructure is implemented at scale, then charging availability for users is improved, but implementation cost and deployment time increase significantly
Solution Approach 1:
The patent introduces a charger adapter as an intermediary device that connects between an existing EV charger and the EV. This adapter enables secure, controlled access to private chargers through remote authentication and switch control, allowing public sharing of private charging infrastructure without requiring new charger installations. The adapter acts as a mediator that bridges the gap between private charger owners and public users.
Solution Approach 2:
The charger adapter is designed with universal compatibility to work with multiple charger manufacturers and platforms. It provides multiple functions including authentication, remote control, usage monitoring, and billing integration, making it a multi-functional solution that can be deployed across diverse charging infrastructures without requiring manufacturer-specific implementations.
2Productivity
If private EV chargers are made accessible to the public, then charging infrastructure scalability is improved, but security against unauthorized use deteriorates
Solution Approach 1:
The system implements feedback mechanisms where the processor continuously monitors authentication status, switch position, and usage parameters. Based on this feedback, the system dynamically controls the switch state to permit or prevent charging. The communication interface also provides feedback to users about authentication status and charging progress, enabling real-time security management.
Solution Approach 2:
The charger adapter serves as a security intermediary between the private charger and public users. It implements authentication protocols and controlled access mechanisms that verify user authorization before permitting charging. The adapter's switch physically controls power flow, providing a security layer that prevents unauthorized access while allowing legitimate users to charge their vehicles.
3Adaptability or versatility
If integration with multiple charger manufacturers is supported, then system versatility is improved, but device complexity increases
Solution Approach 1:
The charger adapter is designed with universal compatibility features that enable it to work with multiple charger manufacturers and platforms. It implements standardized communication protocols and authentication mechanisms that can interface with different charging systems without requiring manufacturer-specific hardware or complex custom integration for each provider.
