Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If spectrum resources are dynamically utilized by secondary systems, then spectrum usage efficiency is improved, but interference to primary systems increases
Solution Approach 1:
The patent segments the spectrum management into primary systems (with usage rights) and secondary systems (without usage rights), allowing dynamic utilization by secondary systems while protecting primary systems through defined exclusion zones and interference limits
Solution Approach 2:
The patent introduces a spectrum management apparatus as an intermediary that coordinates between primary and secondary systems, determining exclusion zones and managing spectrum allocation to balance efficiency and interference protection
2Object-affected harmful factors
If exclusion zones are established to protect primary systems, then interference is reduced, but spectrum resource utilization decreases
Solution Approach 1:
The patent makes exclusion zones dynamic rather than static, allowing them to be adjusted based on primary system activity patterns, thereby protecting primary systems when needed while maximizing spectrum utilization when primary systems are inactive
Solution Approach 2:
The patent changes the parameters of exclusion zones (size, location, duration) based on interference measurements and primary system performance, optimizing the balance between protection and utilization
3Productivity
If spectrum allocation is optimized for secondary systems, then communication efficiency improves, but communication quality stability deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where secondary systems monitor interference levels and communicate quality metrics, allowing the spectrum management apparatus to adjust allocation decisions to maintain stability while optimizing efficiency
