Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple mobility devices are simultaneously wirelessly charged at a single charging station, then the charging service capacity is improved, but charging overload occurs
Solution Approach 1:
The charging management apparatus dynamically adjusts charging parameters (current, voltage, power) based on the number of connected mobility devices and real-time charging status. The controller continuously monitors charging conditions and modifies charging rates to prevent overload while maximizing service capacity, transforming the static charging system into a dynamic adaptive one.
Solution Approach 2:
The system changes charging parameters (current, voltage, power distribution) according to the charging dock ratio and device requirements. By adjusting these parameters in real-time, the system can serve multiple devices simultaneously without exceeding the power supply capacity, thus preventing overload while maintaining high productivity.
2Speed
If the charging current is increased to charge multiple devices faster, then the charging speed is improved, but the power supply capacity is exceeded
Solution Approach 1:
The system applies partial charging current to each device based on the total number of connected devices. Instead of providing full current to each device simultaneously, the controller distributes the available power capacity across multiple devices, ensuring the total power consumption remains within supply limits while still providing charging service to all devices.
Solution Approach 2:
The charging current for each device is dynamically adjusted based on real-time conditions including the number of connected devices, battery charge levels, and power supply capacity. This dynamic adjustment allows the system to optimize charging speed while preventing power supply overload.
3Ease of operation
If the charging voltage is maintained at constant level for all devices, then the charging simplicity is improved, but the charging efficiency decreases under high load
Solution Approach 1:
The charging management apparatus applies different charging voltages and currents to different charging docks based on local conditions such as device type, battery charge level, and dock utilization. Each charging dock receives customized charging parameters optimized for its specific device, improving overall charging efficiency while the controller manages the complexity automatically.
Solution Approach 2:
The system changes charging voltage and current parameters based on the charging dock ratio and device requirements. When the charging dock ratio is high, the system adjusts parameters to optimize power distribution efficiency, thereby maintaining ease of operation while improving charging productivity under high load conditions.
