Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If only one power conversion unit is connected to a user operation unit by a switching circuit, then the charging equipment can maintain simple structure and control, but only one vehicle can be charged at a time, reducing productivity
Solution Approach 1:
The power conversion unit is divided into multiple independent modules (first power conversion unit, second power conversion unit, etc.), each capable of independently converting power. These modular units can be selectively connected to different user operation units through the switching circuit, enabling multiple vehicles to be charged simultaneously while maintaining manageable system complexity through standardized modular architecture.
Solution Approach 2:
The switching circuit is designed with universal connectivity capability, able to connect any power conversion unit to any user operation unit dynamically. This multi-functional switching architecture allows a single charging equipment to serve multiple vehicles with different charging requirements, transforming the system from single-purpose to multi-purpose operation.
2Productivity
If multiple charge converter devices are provided to charge multiple vehicles, then charging productivity increases, but the cost and device complexity increase significantly
Solution Approach 1:
Multiple power conversion units are merged into a single charging equipment system, sharing common control circuits, switching mechanisms, and user operation interfaces. This consolidation allows multiple vehicles to be charged simultaneously through one integrated device rather than requiring separate charge converter devices for each vehicle, reducing overall system complexity and cost.
Solution Approach 2:
The charging system employs dynamic configuration capability where the switching circuit can real-time reconfigure connections between power conversion units and user operation units based on charging demands. This dynamic adaptability allows a fixed number of power conversion units to flexibly serve varying numbers of vehicles, optimizing resource utilization without requiring proportional increases in hardware.
3Ease of operation
If a single charging station charges one vehicle at a time, then equipment complexity remains low, but users experience long waiting times and reduced convenience
Solution Approach 1:
The charging system maintains continuous useful action by enabling parallel charging operations across multiple user operation units. While one vehicle is being charged, the system can simultaneously charge another vehicle through different power conversion units, eliminating idle time and ensuring continuous productive operation, thereby reducing user waiting time and improving overall service continuity.
