Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If frequency secondary utilization is implemented allowing secondary systems to use allocated frequency channels, then frequency resource utilization efficiency is improved, but high-priority wireless networks cannot share frequency bands allocated to other high-priority systems
Solution Approach 1:
The patent extends frequency sharing capability universally among all high-priority wireless networks, not just between primary and secondary systems. The communication control device enables any high-priority network to share frequency bands allocated to other high-priority networks by exchanging availability information and coordinating access, making the frequency sharing mechanism universally applicable across different network types and priorities.
Solution Approach 2:
The communication control device acts as an intermediary between different wireless networks, facilitating frequency sharing by collecting and exchanging availability information about frequency bands. This intermediary coordinates access requests and grants permission for high-priority networks to utilize frequency bands allocated to other high-priority systems, enabling indirect frequency sharing through centralized information exchange.
2Device complexity
If high-priority wireless networks are restricted to using only their own allocated frequency bands, then network management complexity is reduced, but frequency resource utilization efficiency deteriorates
Solution Approach 1:
The communication control device enables high-priority wireless networks to autonomously access frequency bands allocated to other high-priority networks by exchanging availability information. Each network can independently determine which frequency bands are available for sharing and initiate access without complex centralized coordination, allowing self-service frequency sharing that reduces overall management complexity while improving resource utilization.
Solution Approach 2:
The system performs preliminary information exchange about frequency band availability before actual frequency sharing occurs. The communication control device collects and shares availability information in advance, allowing high-priority networks to plan and coordinate their frequency usage beforehand, simplifying the actual access process and reducing real-time management complexity.
