Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If channels are fixedly assigned to UAV CNPC systems, then communication stability is improved, but frequency resource utilization deteriorates
Solution Approach 1:
The patent implements dynamic channel assignment where channels are not fixedly assigned but are allocated based on real-time interference analysis and operational needs. The spectrum access manager continuously monitors channel conditions and reallocates channels between P2P and P2MP systems dynamically, transforming the static channel assignment into a dynamic resource management system that adapts to changing conditions.
Solution Approach 2:
The system changes the parameter of channel assignment from fixed to variable based on interference levels, operational status, and system type. By analyzing interference parameters and adjusting channel allocation accordingly, the system optimizes both communication stability and frequency resource utilization under different operational scenarios.
2Productivity
If channels are dynamically reassigned, then frequency resource utilization is improved, but system complexity increases
Solution Approach 1:
The patent introduces a spectrum access manager as an intermediary component that handles the complex task of interference analysis and channel allocation. This centralized mediator simplifies the system architecture by consolidating the decision-making logic for dynamic channel assignment, reducing the complexity burden on individual UAV systems while enabling efficient frequency resource utilization.
Solution Approach 2:
The system implements feedback mechanisms where interference analysis results are continuously monitored and used to adjust channel assignments. The spectrum access manager receives feedback on channel conditions and system performance, then dynamically adjusts allocations to optimize frequency resource utilization while maintaining manageable system complexity through iterative optimization.
3Measurement precision
If interference analysis is performed, then channel selection accuracy is improved, but processing time increases
Solution Approach 1:
The patent performs preliminary interference analysis and channel suitability evaluation before final channel assignment. By pre-assessing channel conditions and identifying suitable channels in advance, the system reduces the processing time required during actual channel selection while maintaining high accuracy through thorough preliminary evaluation of interference patterns and system requirements.
