Engineering Contradiction Analysis
1Length of stationary object
If conventional magnetic or inductive charging is used, then wireless power delivery is achieved, but the charging range is limited to very close proximity
Solution Approach 1:
The patent combines separate wireless power transmission and data communication circuits into a unified circuit that can perform both functions simultaneously over extended distances, resolving the contradiction between extended range and reliable operation
Solution Approach 2:
The unified circuit is designed to serve multiple functions - both wireless power delivery and bidirectional data communication - eliminating the need for separate dedicated circuits and enabling reliable operation at extended distances
2Adaptability or versatility
If separate circuitry is used for data communication, then data communication capability is achieved, but hardware complexity and power consumption increase
Solution Approach 1:
The patent merges separate wireless power and data communication circuits into a single unified circuit that handles both functions, reducing hardware complexity while maintaining full data communication capability
Solution Approach 2:
The unified circuit is designed with multi-functionality to handle both power transmission and bidirectional data communication, eliminating redundant hardware components and simplifying the overall system architecture
3Adaptability or versatility
If separate circuitry is used for data communication, then data communication is supported, but power consumption increases
