Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two levels of radio frequency transmission lines connected in series are loaded to the ground through a diode to implement switch function, then the switch function is achieved, but the power division and phase-shift functions cannot be implemented
Solution Approach 1:
The patent combines switch, phase-shift, and power division functions into a single integrated radio frequency module. The power division network, impedance adjustment network, and phase-shift filtering network are merged into one unified circuit structure, allowing multiple functions to be achieved simultaneously without requiring separate components for each function.
Solution Approach 2:
The radio frequency module is designed as a multi-functional component where the power division network can allocate power to different branch circuits, the impedance adjustment network can adjust impedance values, and the phase-shift filtering network can control output status and phase. This universal design allows a single module to perform switch, phase-shift, and power division functions that previously required separate components.
2Reliability
If separate components are used for switch, phase-shift, and power division functions, then each function can be implemented independently, but the overall device complexity increases
Solution Approach 1:
The patent merges previously separate switch, phase-shift, and power division components into a single integrated radio frequency module. The power division network, impedance adjustment network, and phase-shift filtering network are combined in one unified structure, reducing the total number of components while maintaining functional independence through proper circuit design.
Solution Approach 2:
The integrated module achieves multi-functionality where the power division network can independently control power allocation to different branch circuits, the impedance adjustment network can independently adjust impedance values, and the phase-shift filtering network can independently control output status and phase. This allows functional independence without requiring separate physical components for each function.
3Adaptability or versatility
If a single radio frequency module implements multiple functions, then integration is improved, but the circuit design complexity increases
Solution Approach 1:
The patent segments the integrated radio frequency module into distinct functional sub-networks: the power division network, the impedance adjustment network, and the phase-shift filtering network. Each sub-network is designed and optimized independently, then integrated into the complete module. This segmentation approach allows complex multi-functional integration while managing design complexity through modular architecture.
Solution Approach 2:
The circuit design achieves multi-functionality through a universal architecture where the power division network can allocate power to different branch circuits, the impedance adjustment network can adjust impedance values, and the phase-shift filtering network can control output status and phase. This universal design allows a single integrated module to perform multiple functions that previously required separate components, improving integration while managing design complexity through systematic circuit architecture.
