Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the wireless energy sending device performs phase calibration on all emitter nodes for each receiving device in turn, then the energy transmission effect for each device is optimized, but the charging time becomes unbalanced and excessively long for multiple devices
Solution Approach 1:
The patent segments the emitter nodes into multiple groups, where each group is responsible for transmitting energy to a specific receiving device. This segmentation allows parallel operation of different emitter groups, eliminating the need for sequential phase calibration across all devices. Each emitter group performs phase calibration independently and simultaneously with other groups, significantly reducing total charging time while maintaining optimal energy transmission effects.
Solution Approach 2:
The patent merges the phase calibration processes of multiple emitter groups by performing them simultaneously rather than sequentially. The control unit coordinates multiple emitter groups to conduct phase calibration in parallel, combining what was previously a series of sequential operations into concurrent operations, thereby reducing the overall time loss while preserving the precision of energy transmission optimization.
2Adaptability or versatility
If the wireless energy sending device shares energy transmission with multiple receiving devices in turn, then the device can serve multiple users, but the states of charge cannot remain balanced
Solution Approach 1:
The patent divides the emitter nodes into separate groups, with each group dedicated to serving a specific receiving device simultaneously. This segmentation enables the system to serve multiple devices in parallel rather than in turns, maintaining balanced charging states across all devices while preserving full service capability for multiple users.
Solution Approach 2:
The patent implements dynamic control of emitter node distribution, where the control unit can dynamically adjust which emitter nodes are assigned to which receiving devices based on real-time charging states. This dynamic allocation ensures that devices with lower charge levels receive more energy transmission resources, automatically maintaining balanced states of charge while serving multiple users concurrently.
3Power
If all emitter nodes are used for each receiving device sequentially, then complete energy transmission is achieved, but the charging processes complete at different times causing imbalance
Solution Approach 1:
The patent segments the total emitter nodes into multiple groups that operate in parallel on different receiving devices. Each emitter group transmits energy at full power to its assigned device simultaneously, rather than one device at a time. This segmentation maintains complete energy transmission power for each device while dramatically improving overall charging efficiency by eliminating sequential delays.
Solution Approach 2:
The patent enables continuous useful action by having multiple emitter groups transmit energy to multiple receiving devices simultaneously and continuously. Instead of interrupting energy transmission to switch between devices, the system maintains continuous transmission across all devices in parallel, improving productivity while preserving the power intensity needed for complete energy transmission.
