Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If static antenna configurations are used in wireless power transmission systems, then device complexity is reduced, but wireless power transfer efficiency deteriorates in multipath environments
Solution Approach 1:
The patent implements dynamically reconfigurable antenna configurations that can adapt their radiation patterns, polarization, and beam widths in real-time based on multipath channel conditions. This allows the system to optimize power transfer efficiency by adjusting antenna parameters dynamically rather than using fixed configurations, directly resolving the contradiction between simplicity and efficiency.
Solution Approach 2:
The system changes antenna parameters (radiation pattern, polarization, gain/beam width) based on measured channel conditions to optimize power transfer. By monitoring received power characteristics and adjusting antenna parameters accordingly, the system overcomes the efficiency limitations of static configurations while maintaining manageable complexity through controlled parameter adjustment.
2Loss of energy
If reconfigurable antenna configurations are implemented, then wireless power transfer efficiency is improved, but device complexity increases
Solution Approach 1:
The patent employs feedback mechanisms where the wireless power receiver measures received power characteristics and communicates channel state information back to the transmitter. This feedback enables the system to optimize antenna configurations based on actual channel conditions, achieving high efficiency while managing complexity through intelligent control rather than brute-force configuration options.
Solution Approach 2:
The system performs self-optimization by automatically monitoring power transfer characteristics and adjusting antenna configurations without external intervention. The wireless power receiver and transmitter work autonomously to identify optimal antenna settings based on measured channel conditions, reducing the need for complex external control systems.
3Reliability
If antenna configurations are dynamically adjusted, then power reception reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The system automatically monitors power transfer characteristics and adjusts antenna configurations without requiring user intervention. The wireless power receiver and transmitter autonomously optimize their operation based on measured channel conditions, maintaining high reliability while preserving ease of operation through self-configuration.
Solution Approach 2:
The feedback mechanism continuously monitors power transfer efficiency and automatically triggers antenna reconfiguration when performance degradation is detected. This closed-loop control ensures reliable power reception while maintaining operational simplicity, as the system self-corrects without user involvement.

AI summary
The technology described herein relates to wireless power receivers with reconfigurable (or adaptive) antenna configurations for improved wireless power transfer in multipath wireless power delivery environments. In an implementation, a wireless power receiver is described. The wireless power receiver includes one or more radio frequency (RF) antennas, power metering circuitry and control circuitry. The power metering circuitry is adapted to measure at least one characteristic of wireless power received from a wireless power transmission system in a multipath environment. The control circuitry is adapted to monitor the power metering circuitry to determine when the measure of the at least one characteristic of the wireless power fails to meet a preset threshold, and dynamically reconfigure an antenna configuration of the wireless power receiver when the at least one characteristic of the wireless power fails to meet the preset threshold.
