Engineering Contradiction Analysis
1Adaptability or versatility
If additional antennas are deployed for UWB positioning, RF charging, and multi-band communication, then functional versatility is improved, but device complexity and space occupation increase
Solution Approach 1:
The patent applies universality by designing a single antenna module that can perform multiple functions including UWB positioning, RF charging, and multi-band communication. The antenna module is configured to support different communication protocols and frequency bands, allowing one antenna structure to replace what would traditionally require multiple separate antennas, thereby reducing device complexity while maintaining functional versatility
Solution Approach 2:
The patent merges multiple antenna functions into a single integrated antenna module. By combining UWB, RF charging, and multi-band communication capabilities into one antenna structure, the patent reduces the number of separate components needed, simplifying the overall device architecture and reducing space occupation while preserving all required functionalities
2Adaptability or versatility
If additional antennas are deployed for diverse functions, then functional versatility is improved, but space occupation increases
Solution Approach 1:
The antenna module is designed with universal functionality to handle UWB positioning, RF charging, and multi-band communication within a single compact structure. This multi-functional design allows the antenna to serve multiple purposes without requiring additional space for separate antenna elements, thereby maintaining functional versatility while minimizing space occupation
Solution Approach 2:
Multiple antenna functions are merged into one integrated module, consolidating what would traditionally require multiple separate antenna elements into a single compact unit. This merging approach significantly reduces the total space required for antenna deployment while maintaining all necessary communication and charging functionalities
