Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single source resonator is used for wireless power transmission, then the device structure is simple, but the charging efficiency decreases when devices are at different locations or orientations
Solution Approach 1:
The source unit is divided into multiple source resonators (first source resonator and second source resonator) that are disposed at different locations and/or orientations. Each source resonator can independently transmit wireless power to target resonators, ensuring that devices regardless of their position or orientation can receive power efficiently.
Solution Approach 2:
The patent introduces spatial dimensionality by disposing source resonators in different orientations (e.g., perpendicular to each other) and locations. This multi-dimensional arrangement ensures comprehensive power transmission coverage in three-dimensional space, solving the problem of orientation-dependent charging efficiency.
2Loss of energy
If multiple source resonators are disposed in different locations and orientations, then wireless power transmission efficiency improves for devices at any location, but the device complexity increases
Solution Approach 1:
The source unit is designed with multiple source resonators that collectively provide universal power transmission capability in all directions and orientations. This multi-functional configuration allows a single source unit to serve multiple devices simultaneously regardless of their spatial arrangement, justifying the increased complexity through enhanced versatility.
Solution Approach 2:
Multiple source resonators are combined within a single source unit structure. The resonators work together in a coordinated manner, with each contributing to the overall power transmission field. This merging approach consolidates the complexity into a unified system rather than separate independent units.
3Ease of operation
If devices are charged wirelessly using resonators, then convenience is improved, but charging efficiency decreases due to location and angle constraints
Solution Approach 1:
The wireless charging system is segmented into multiple source resonators positioned at different locations and orientations. This segmentation ensures that regardless of where a device is placed or what orientation it has, at least one source resonator can transmit power efficiently, maintaining both convenience and efficiency.
Solution Approach 2:
By adding spatial dimensionality with resonators disposed in perpendicular orientations and different locations, the system eliminates orientation constraints. Users can place devices freely in three-dimensional space without worrying about alignment, preserving convenience while ensuring efficient power transfer.
4Device complexity
If a single target resonator is used in a device, then the device structure is simple, but it cannot receive power efficiently from source resonators at all orientations
Solution Approach 1:
The device is divided into multiple target resonators (first target resonator and second target resonator) that are disposed at different orientations within the device. Each target resonator is tuned to resonate at the same frequency as the source resonators, enabling the device to efficiently receive power from source resonators regardless of their orientation or location.
