Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If wireless charging is limited to small areas or specific configurations, then device compatibility and power transfer efficiency are maintained, but the charging surface area and multi-device charging capability are restricted
Solution Approach 1:
The charging surface is divided into multiple independently controllable coil regions. Each coil can be selectively activated based on device location and charging requirements, enabling large surface area coverage while maintaining manageable system complexity through modular control
Solution Approach 2:
The system dynamically adjusts which coils are active based on real-time device detection and location. This dynamic activation allows the charging surface to adapt to different device configurations and positions, providing full surface charging capability without continuously powering all coils
2Productivity
If multiple devices are charged simultaneously on a full surface, then charging capacity and user convenience are improved, but the ability to provide specific location-based charge status feedback becomes difficult
Solution Approach 1:
Each coil region is associated with specific output devices positioned at corresponding locations. The system provides charge status feedback through local indicators (LEDs, displays, or audio) that are spatially correlated with the charging position, maintaining accurate location-based feedback even when multiple devices are charged simultaneously
Solution Approach 2:
The system continuously receives charging status information from each device and provides real-time feedback through output devices. This feedback loop enables the system to monitor and communicate the charge status of multiple devices simultaneously, with each device's status indicated at its corresponding location on the charging surface
