Engineering Contradiction Analysis
1Ease of operation
If distributed antennas are fixedly associated with signal processing units, then device complexity is reduced and ease of operation is improved, but adaptability to load variations deteriorates and productivity decreases
Solution Approach 1:
The patent implements dynamic reassignment of distributed antennas to signal processing units based on real-time load information. The management unit continuously monitors load levels and reallocates antennas from overloaded units to underloaded units, transforming the static antenna-processor association into a dynamic, adaptive system that responds to changing traffic conditions.
2Device complexity
If distributed antennas are fixedly associated with signal processing units, then device complexity is reduced, but adaptability to load variations deteriorates and productivity decreases
Solution Approach 1:
The system introduces dynamic reassignment capability where the management unit monitors load information and reallocates antennas between signal processing units based on current conditions. This dynamic mechanism adds adaptability without requiring fundamental changes to the overall system architecture.
Solution Approach 2:
The patent implements a feedback mechanism where load information from signal processing units is continuously monitored and fed back to the management unit. Based on this feedback, the management unit makes intelligent decisions about antenna reassignment, creating a closed-loop control system that adapts to changing conditions.
3Ease of operation
If distributed antennas are fixedly associated with signal processing units, then ease of operation is improved, but productivity decreases due to load imbalance
Solution Approach 1:
The system dynamically reassigns antennas to balance load across signal processing units, preventing overload conditions that reduce productivity. By continuously monitoring and adjusting antenna assignments, the system maintains optimal operation levels and prevents throughput degradation.
Solution Approach 2:
The management unit uses feedback from load information to make real-time adjustments in antenna allocation. This feedback-driven approach ensures that productivity is maintained by preventing load imbalance, while the automated nature of the process preserves ease of operation.
4Ease of operation
If distributed antennas are fixedly associated with signal processing units, then device complexity is reduced and ease of operation is improved, but adaptability to load variations deteriorates
Solution Approach 1:
The patent implements dynamic antenna reassignment that responds to changing load conditions, preventing signal processing units from becoming overloaded. This dynamic adaptation improves reliability by ensuring that no single unit becomes a bottleneck, maintaining consistent system performance under varying conditions.
