Engineering Contradiction Analysis
1Productivity
If polarization-based communication or beam-based communication is used to improve transmission efficiency, then communication performance can be enhanced, but antenna misalignment reduces reception efficiency
Solution Approach 1:
The patent implements a feedback mechanism where the receiving node detects the electric field magnitude of received signals and feeds back alignment information to the transmitting node. The transmitting node then adjusts its transmit antenna alignment based on this feedback, creating a closed-loop system that continuously optimizes the alignment state to maximize reception efficiency while maintaining high transmission efficiency.
Solution Approach 2:
The system enables self-adjustment of antenna alignment through automatic detection and adjustment processes. The receiving node autonomously detects electric field characteristics and provides feedback, while the transmitting node autonomously adjusts its antenna alignment based on received feedback, eliminating the need for manual intervention and实现ing self-optimized communication.
2Reliability
If manual antenna alignment adjustment is performed to improve reception efficiency, then transmission efficiency can be maximized, but system complexity and signaling overhead increase
Solution Approach 1:
The system enables self-adjustment of antenna alignment through automatic detection and adjustment processes. The receiving node autonomously detects electric field characteristics and provides feedback, while the transmitting node autonomously adjusts its antenna alignment based on received feedback, eliminating the need for manual intervention and reducing system complexity.
Solution Approach 2:
The patent replaces manual mechanical adjustment of antenna alignment with an automated electronic control system. The system uses electric field detection and electronic feedback mechanisms to automatically adjust antenna alignment, substituting manual mechanical operations with electronic automation, thereby reducing system complexity and signaling overhead.
3Reliability
If separate feedback and antenna adjustment procedures are implemented to optimize alignment, then reception efficiency improves, but signaling overhead and system complexity increase
Solution Approach 1:
The patent merges the feedback provision and antenna adjustment processes into a unified, streamlined procedure. The receiving node incorporates alignment detection into its normal signal reception operations, and the transmitting node integrates alignment adjustment into its existing signal transmission framework, combining multiple functions into integrated processes that reduce signaling overhead.
Solution Approach 2:
The system implements multi-functional components that perform multiple tasks simultaneously. The electric field detection mechanism serves both signal quality assessment and alignment optimization functions, while the feedback channel carries both data transmission and alignment information, reducing the need for separate dedicated procedures and minimizing signaling overhead.
