Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antennas are used to receive signals in the same frequency band simultaneously, then communication performance is improved, but device complexity increases due to connection limitations between antennas and RF circuits
Solution Approach 1:
The patent employs a switching circuit that dynamically reconfigures the connection between antennas and RF circuits based on operational requirements. The switching circuit can establish different connection paths (first connection and second connection) to enable multiple antennas to simultaneously receive signals in the same frequency band, thereby improving communication performance while managing system complexity through adaptive connection management.
2Reliability
If multiple antennas are connected to the same RF circuit, then signal reception capability is improved, but the ability to transmit and receive signals simultaneously in the same frequency band is restricted
Solution Approach 1:
The patent segments the RF circuit into multiple independent units (first RF circuit and second RF circuit), each capable of independent operation. The switching circuit connects different antennas to different RF circuit units, enabling one antenna to receive signals while another antenna transmits signals in the same frequency band simultaneously. This segmentation allows the system to overcome the limitation of single RF circuit sharing and achieve simultaneous transmit and receive functionality.
3Reliability
If all antennas are actively used for communication, then communication performance is maximized, but power consumption increases
Solution Approach 1:
The switching circuit dynamically selects and activates only the necessary antennas and RF circuit units based on current communication requirements and signal conditions. By controlling the switching circuit to establish connections only when needed, the system can reduce power consumption by keeping unused antennas and RF circuits in a low-power or inactive state, while maintaining optimal communication performance through selective activation of the most effective antenna paths.
