Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple mobility devices are simultaneously wirelessly charged at a single charging station, then the charging capacity and productivity are improved, but charging overload occurs and system reliability deteriorates
Solution Approach 1:
The charging station dynamically adjusts charging parameters (current, voltage, power allocation) in real-time based on the number of connected mobility devices and their individual charging states. This dynamic control prevents overload while maintaining high charging capacity by continuously optimizing the charging distribution across multiple devices.
Solution Approach 2:
The system changes charging parameters (current, voltage, power allocation ratios) based on the charging dock ratio and device requirements. By adjusting these parameters dynamically, the system can charge multiple devices simultaneously without exceeding the station's power capacity, thus preventing overload while maintaining productivity.
2Speed
If the charging station supplies maximum power to all charging docks, then the charging speed is improved, but the risk of overload and system failure increases
Solution Approach 1:
The system adjusts charging parameters (current, voltage, power allocation) based on the charging dock ratio and individual device needs. By dynamically changing these parameters, the system maintains high charging speeds while preventing overload conditions that could lead to system failure.
Solution Approach 2:
The charging station continuously monitors the charging state of each device and the overall system load, then adjusts power allocation accordingly. This feedback mechanism ensures that charging speed is optimized while preventing overload by reducing power to individual devices when the total load approaches system capacity.
3Device complexity
If the charging station manages multiple charging devices with fixed charging modes, then the device complexity is reduced, but the adaptability to different charging scenarios deteriorates
Solution Approach 1:
The charging station transitions from fixed charging modes to dynamic mode selection, automatically determining the appropriate charging mode (constant current, constant voltage, or power allocation) based on the charging dock ratio and device requirements. This dynamic approach maintains system simplicity while significantly improving adaptability to different charging scenarios.
Solution Approach 2:
The charging station implements a universal control system that can handle multiple charging modes and device types through a single adaptive framework. By making the control system multi-functional and scenario-aware, it maintains simplicity while gaining the flexibility to adapt to various charging conditions and device requirements.
