Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If AC charging systems are used, then charging system cost and complexity is reduced, but energy management capability deteriorates due to lack of data feedback
Solution Approach 1:
The patent implements a feedback mechanism where the vehicle module transmits data back to the charging station and remote server. This includes vehicle identification, positioning information, and charging status data, enabling the system to monitor and manage energy distribution effectively despite using simpler AC charging infrastructure.
Solution Approach 2:
The patent introduces a remote server as an intermediary that coordinates between vehicles and charging stations. The server receives positioning data and vehicle identifiers, manages authentication, and controls energy allocation, thereby compensating for the limited data feedback capability of AC charging systems through centralized intelligence.
2Reliability
If third-party authentication systems are used, then charging management capability is improved, but user convenience deteriorates due to required authentication steps
Solution Approach 1:
The patent implements self-service authentication where the vehicle module automatically provides identification and positioning data without requiring user intervention. The system autonomously authenticates vehicles through their inherent identifiers (such as VIN) and location information, eliminating the need for smartphones, RFID tags, or manual authentication processes.
Solution Approach 2:
The patent replaces mechanical authentication systems (RFID cards, smartphone apps, fuel cards) with an automated electronic identification system. The vehicle module uses the vehicle's existing identification systems and GPS positioning to automatically authenticate and initiate charging, substituting manual authentication mechanisms with automated electronic verification.
3Adaptability or versatility
If public vehicle charging infrastructure is deployed, then accessibility is improved, but investment cost increases making deployment difficult
Solution Approach 1:
The patent creates a universal charging management system that can serve multiple vehicles and multiple charging stations through a single remote server platform. The system is designed to be multi-functional, handling authentication, positioning, energy management, and billing across a network of charging infrastructure, thereby reducing per-unit investment complexity through shared centralized services.
Solution Approach 2:
The remote server acts as an intermediary that enables shared use of charging infrastructure without requiring each station to have complex independent management systems. The server centralizes investment and operational complexity, allowing individual charging stations to be simpler and more cost-effective while maintaining coordinated operation across the network.
