Engineering Contradiction Analysis
1Reliability
If a conventional wireless power transmission system uses a simple planar resonator structure, then the device complexity is low and manufacturing is easier, but the power transmission efficiency deteriorates when the location or angle of the charging device changes
Solution Approach 1:
The patent transitions from a planar two-dimensional resonator structure to a three-dimensional stereoscopic structure by stacking multiple cells in vertical layers. This dimensional change enables the resonator to maintain efficient magnetic coupling over greater distances and at various angles, solving the problem of power transmission efficiency degradation when device position changes.
Solution Approach 2:
The resonator is divided into multiple discrete cells (first cell, second cell, third cell, fourth cell) that can be independently configured and connected. Each cell contains conductive patterns and capacitive elements that work together to create the overall three-dimensional resonant structure, allowing modular assembly and optimized magnetic field distribution.
2Reliability
If the wireless power transmission system requires precise placement of the charging device, then power transmission efficiency is maintained, but the ease of operation deteriorates due to user inconvenience
Solution Approach 1:
By creating a three-dimensional resonant structure with cells stacked in multiple layers, the system expands its effective coupling volume. This allows the charging device to maintain efficient power transmission across a broader range of positions and orientations, eliminating the need for precise placement and significantly improving user convenience.
3Reliability
If a stereoscopic flexible resonator with cross-configuration of cells is used, then power transmission efficiency is maintained across varying locations and angles, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The complex three-dimensional resonator is segmented into multiple identical or similar cells that can be manufactured using the same processes. Each cell contains conductive patterns on substrates with capacitive elements, which can be produced through standardized PCB or flexible circuit board manufacturing techniques, then assembled and connected to form the complete resonator structure.
Solution Approach 2:
Multiple cells are designed with identical or similar structures that perform the same function within the resonator system. This universality allows for standardized manufacturing processes, reducing overall manufacturing complexity despite the three-dimensional configuration. The same manufacturing techniques and assembly procedures can be applied to each cell.
