Problem
Current communication devices and systems face challenges in optimizing performance and cost when using multiple communication standards due to the need to choose between single or multiple antennas, limiting flexibility and user-friendliness.
Innovation Solution
A communications device and system that includes a switch with multiple terminals to alternate between different antenna configurations, allowing a single antenna or multiple antennas to be used based on user preference, while optimizing production costs and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single antenna is used for multiple communication standards, then production cost is reduced, but performance is compromised
Solution Approach 1:
The patent implements a dynamic antenna configuration where the system can switch between single-antenna and multi-antenna modes based on operational requirements. The switch component enables the antenna to be dynamically connected to different communication circuits, allowing the device to adapt its antenna configuration rather than being fixed in one state.
2Reliability
If multiple antennas are used for different communication standards, then performance is optimized, but production cost increases
Solution Approach 1:
The patent makes the single antenna multi-functional by enabling it to serve multiple communication standards through the switch mechanism. The antenna can be connected to different communication circuits (first and second communication circuits) depending on which standard is being used, making one antenna perform the work of multiple dedicated antennas when cost is a constraint.
3Device complexity
If a fixed antenna configuration is chosen, then device complexity is reduced, but flexibility is limited
Solution Approach 1:
The patent implements a dynamic antenna configuration where the system can switch between single-antenna and multi-antenna modes based on operational requirements. The switch component enables the antenna to be dynamically connected to different communication circuits, allowing the device to adapt its antenna configuration rather than being fixed in one state.
