Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple independent charging facilities are provided to accommodate different vehicle types, then charging versatility is improved, but device complexity and cost increase
Solution Approach 1:
The charging facility uses a single modular charging unit with reconfigurable power outputs that can be dynamically adjusted to match different vehicle requirements. The system provides universal charging capability by changing voltage and current parameters rather than using separate specialized chargers for each vehicle type.
Solution Approach 2:
The charging system is divided into modular power output units that can be independently configured and combined. Each module can operate separately or be aggregated to provide different power levels, allowing the system to adapt to various charging needs without requiring completely different charging facilities.
2Productivity
If high power charging is applied to reduce charging time, then charging speed is improved, but power availability and system complexity increase
Solution Approach 1:
The charging system dynamically reconfigures its power outputs during operation, adjusting voltage and current levels in real-time based on the connected vehicle's requirements. This dynamic adaptability allows the system to provide high power when needed while maintaining simpler operation for standard charging scenarios.
Solution Approach 2:
Multiple isolated DC power outputs are combined through a switching assembly to deliver aggregated high power to a single vehicle when required. The system merges multiple power modules to achieve high power charging capability, rather than requiring a single complex high-power converter.
3Adaptability or versatility
If multiple isolated DC power outputs are provided to meet different voltage and current requirements, then charging adaptability is improved, but device complexity increases
Solution Approach 1:
The system changes its electrical parameters (voltage and current) by reconfiguring the connection topology of multiple isolated DC power outputs. By switching between series and parallel configurations, the system generates different voltage and current levels to match various vehicle charging specifications without requiring separate power sources.
Solution Approach 2:
A switching assembly acts as an intermediary between the multiple isolated DC power outputs and the charging outlet. This switching component enables flexible reconfiguration of the power outputs to match different charging requirements, simplifying the overall system architecture by providing a single point of adaptation rather than multiple fixed-output chargers.
