Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed magnetic field barrier configuration is used to shield components from magnetic field interference, then component protection is improved, but wireless charging functionality in multiple device orientations is lost
Solution Approach 1:
The magnetic field barrier is designed with movable portions that can transition between different positions. The barrier includes a fixed portion and a movable portion that can be positioned to either block or allow magnetic field passage, enabling the system to adapt between shielding mode and wireless charging mode based on device orientation
Solution Approach 2:
The magnetic field barrier is divided into multiple segments including a fixed portion and a movable portion. This segmentation allows independent control of different barrier sections, enabling selective shielding of components while maintaining wireless charging capability in specific orientations
2Adaptability or versatility
If the magnetic field barrier is positioned to allow wireless charging, then charging functionality is improved, but component protection from magnetic field interference is reduced
Solution Approach 1:
The movable portion of the magnetic field barrier can be dynamically positioned based on device orientation. When the device is in a charging orientation, the movable portion is positioned to allow magnetic field passage for charging. When the device orientation changes, the movable portion transitions to block the magnetic field and protect components
Solution Approach 2:
The system proactively positions the movable barrier portion before magnetic field exposure occurs. The barrier is pre-configured to automatically transition to protective position when device orientation changes, preventing magnetic field interference to components before it can occur
