Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If one non-contact charger charges one device, then charging efficiency is maintained, but the system cannot charge multiple devices simultaneously without vibration interference
Solution Approach 1:
The charging apparatus detects the charged state of each device and identifies which devices are in vibration mode. Based on this feedback, the controller selectively cancels vibration modes only for devices that would disrupt charging, rather than controlling all devices uniformly. This targeted feedback approach maintains charging efficiency while enabling multi-device charging.
Solution Approach 2:
Instead of applying vibration cancellation uniformly to all charged devices, the system applies vibration mode cancellation selectively only to specific devices that are in vibration mode and would disrupt charging. This localized approach addresses the problem precisely where needed while preserving the ability to charge multiple devices simultaneously.
2Reliability
If vibration mode is cancelled for one device during charging, then charging efficiency is maintained, but another device in vibration mode can still disrupt the entire charging process
Solution Approach 1:
The system continuously detects the charged state and vibration mode status of each device individually. Based on this real-time feedback, the controller dynamically adjusts vibration cancellation control for each device, enabling the system to adapt to different device states and maintain charging efficiency across multiple devices.
Solution Approach 2:
The controller changes the operational parameter (vibration mode status) of specific devices based on their individual states and their impact on charging efficiency. By selectively modifying the vibration parameter for affected devices while leaving others unchanged, the system adapts to handle multiple devices with different modes effectively.
