Engineering Contradiction Analysis
1Ease of manufacture
If a fixed coil configuration is used in wireless charging devices, then the device structure is simple and manufacturing is easier, but the electromagnetic coupling efficiency varies significantly when interacting with multiple devices having different coil arrangements
Solution Approach 1:
The patent applies the dynamics principle by making the coil structure adjustable rather than fixed. The coil can dynamically change its configuration (size, shape, orientation) to adapt to different wireless charging devices, thereby maintaining reliable electromagnetic coupling efficiency across multiple device types while keeping the manufacturing process relatively simple.
Solution Approach 2:
The patent implements parameter changes by allowing the coil's physical parameters (such as loop area, orientation angle, and configuration) to be adjusted based on the specific device being charged. This enables the system to optimize electromagnetic coupling efficiency for each device type without requiring completely different coil designs.
2Adaptability or versatility
If the coil configuration is made adjustable to adapt to different devices, then the electromagnetic coupling efficiency and versatility improve, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The coil is designed with dynamic adjustability, allowing it to change its configuration based on the charging device being used. This dynamic capability enables the single coil to replace multiple fixed configurations, improving versatility without proportionally increasing overall system complexity.
Solution Approach 2:
The adjustable coil serves multiple functions by being capable of interacting with various device types through configuration changes. This universal design allows one coil structure to perform the role of what would traditionally require multiple specialized coils, thereby improving adaptability while managing complexity.
3Adaptability or versatility
If the coil configuration is made adjustable to adapt to different devices, then the electromagnetic coupling efficiency and versatility improve, but the manufacturing precision requirements and production difficulty increase
Solution Approach 1:
The dynamic adjustment capability allows the coil to achieve precise configurations during operation rather than requiring extreme manufacturing precision for each possible configuration. The adjustment mechanism compensates for manufacturing tolerances by enabling post-manufacturing configuration optimization.
Solution Approach 2:
The system performs preliminary detection of the target device characteristics and then adjusts the coil configuration accordingly before power transfer begins. This preliminary action allows the system to optimize coupling efficiency without requiring the coil to be pre-configured with extreme precision for all possible device types.
