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 connection complexity between antennas and RF circuits increases
Solution Approach 1:
The patent divides the RF circuit system into multiple independent Tx/Rx circuits (first Tx/Rx circuit and second Tx/Rx circuit), each capable of handling different frequency ranges. This segmentation allows each antenna to be connected to dedicated circuitry, simplifying the overall connection architecture while enabling simultaneous signal reception in the same frequency band through multiple independent paths.
Solution Approach 2:
The patent designs the Rx circuit to support both the first frequency range and the second frequency range, making it a multi-functional component. This universality allows a single Rx circuit to handle signals from different frequency bands, reducing the need for separate dedicated circuits for each frequency range and simplifying the antenna-RF circuit connection structure.
2Productivity
If multiple antennas are connected to multiple Tx/Rx circuits, then simultaneous signal transmission and reception is enabled, but power consumption increases
Solution Approach 1:
The patent introduces a switching circuit that dynamically connects antennas to different Tx/Rx circuits based on operational requirements. This dynamic switching capability allows the system to activate only the necessary circuits for current communication tasks, enabling simultaneous signal transmission and reception when needed while reducing power consumption during normal operation by keeping unnecessary circuits in standby mode.
3Adaptability or versatility
If a switching circuit is used to manage antenna connections, then antenna selection flexibility is improved, but circuit complexity increases
Solution Approach 1:
The patent designs the switching circuit with pre-configured connection paths between antennas and Tx/Rx circuits. The switching circuit is structured to enable rapid connection switching between different antenna-circuit pairs without requiring complex real-time decision-making logic. This preliminary structuring of connection paths provides antenna selection flexibility while keeping the switching circuit architecture relatively simple.
