Engineering Contradiction Analysis
1Quantity of substance
If a time division mechanism with gating switch is used to share antennas between 5 GHz Wi-Fi and 2.4 GHz Wi-Fi, then the number of antennas is reduced, but the data throughput of Wi-Fi and LTE is seriously affected
Solution Approach 1:
The patent employs dynamic switching mechanisms where gating switches dynamically connect different antennas to different communication modules based on real-time signal requirements. The system can dynamically allocate antenna resources between 5 GHz Wi-Fi, 2.4 GHz Wi-Fi, and LTE without fixed time division, maintaining high data throughput while reducing antenna count through adaptive resource allocation.
Solution Approach 2:
The patent designs antennas with multi-functionality to serve multiple communication protocols. A single antenna can function as a primary or secondary antenna for different frequency bands and communication standards (Wi-Fi 5 GHz, Wi-Fi 2.4 GHz, LTE) through the gating switch configuration, reducing the total number of antennas required while maintaining full functionality.
2Productivity
If multiple antennas are used to support 5 GHz Wi-Fi, 2.4 GHz Wi-Fi, and LTE functions, then the data throughput is maintained, but the terminal space for antennas is insufficient
Solution Approach 1:
The patent merges the functions of multiple dedicated antennas into a shared antenna system. By combining the primary and secondary antenna functions for different frequency bands into a smaller set of physical antennas controlled by gating switches, the system reduces the total antenna count and required terminal space while preserving the data throughput capability through intelligent signal routing.
Solution Approach 2:
The patent utilizes parameter changes in the gating switch configuration to dynamically alter which antenna is connected to which communication module. This allows the same physical antenna infrastructure to support multiple frequency bands and protocols simultaneously or sequentially, reducing space requirements while maintaining performance.
3Adaptability or versatility
If a gating switch is used to switch antennas for different frequency bands, then the antenna sharing is achieved, but the data throughput of Wi-Fi and LTE is seriously affected
Solution Approach 1:
The patent implements dynamic antenna switching where the gating switch continuously or periodically reconfigures antenna connections based on active communication protocols. This dynamic approach allows the system to maintain high data throughput for the currently active protocol (whether 5 GHz Wi-Fi, 2.4 GHz Wi-Fi, or LTE) while still providing antenna sharing capability across different frequency bands.
