Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of phase conversion units increases to support 64 antennas in 5G MIMO systems, then the antenna capacity and service capability are improved, but the phase synchronization between multiple phase conversion units deteriorates
Solution Approach 1:
The patent divides the phase conversion system into multiple independent phase conversion units, each capable of autonomous phase conversion. This segmentation allows each unit to operate independently while maintaining overall system functionality, addressing the challenge of managing 64 antenna connections without compromising phase synchronization across all units.
Solution Approach 2:
The patent combines multiple phase conversion units into a single integrated phase shifter structure with a unified control mechanism. By merging the units under common control, the system achieves coordinated phase conversion across all 64 antenna connections, ensuring phase synchronization is maintained despite the large number of units.
2Quantity of substance
If multiple phase conversion units are connected to handle 64 antennas, then the system capacity for 5G service is improved, but the complexity of the phase shifter structure increases
Solution Approach 1:
The phase shifter is segmented into multiple identical or similar phase conversion units, each handling a portion of the 64 antenna connections. This modular segmentation reduces the complexity of designing and managing the overall system by breaking it down into manageable, standardized components that can be replicated and controlled uniformly.
3Adaptability or versatility
If the number of phase conversion units increases, then the beamforming capability for 5G MIMO is enhanced, but the phase consistency across units deteriorates
Solution Approach 1:
The patent merges multiple phase conversion units into a unified phase shifter system with centralized control. This merging ensures that all units operate under coordinated control, maintaining phase consistency across the entire system while enabling advanced beamforming capabilities for 5G MIMO applications.
