Engineering Contradiction Analysis
1Quantity of substance
If wireless spectrum resources are allocated to meet increasing demand for higher-bandwidth content, then bandwidth availability is improved, but spectrum scarcity and regulatory constraints worsen
Solution Approach 1:
The patent segments the wireless spectrum into multiple tiers (first tier, second tier, third tier) with different access rights and priorities. Each tier can independently allocate and share spectrum resources, allowing simultaneous满足不同需求 while maintaining regulatory compliance. This segmentation enables multiple systems to coexist in the same frequency band without interference.
Solution Approach 2:
The patent implements a nested structure where second tier systems operate within unused first tier spectrum resources, and third tier systems operate within unused second tier resources. This nested allocation allows efficient utilization of spectrum resources across multiple layers, maximizing bandwidth availability while respecting hierarchical access rights and regulatory constraints.
2Speed
If higher data throughput is delivered to meet consumer demand, then data transmission speed is improved, but spectrum resource utilization worsens
Solution Approach 1:
The patent establishes feedback mechanisms where each tier monitors and reports unused spectrum resources to lower tiers. This feedback enables dynamic reallocation of spectrum resources based on actual usage patterns, ensuring that spectrum resources are fully utilized while maintaining high data throughput. The feedback loop prevents waste and optimizes resource efficiency.
Solution Approach 2:
The patent changes the parameter of spectrum allocation from static to dynamic by allowing lower tiers to access higher tier resources when those resources are unused. This parameter change enables the system to adapt spectrum allocation in real-time, maximizing both data throughput and resource utilization efficiency without requiring additional spectrum resources.
3Productivity
If multi-tiered spectrum sharing is implemented, then spectrum utilization efficiency is improved, but system complexity worsens
Solution Approach 1:
The patent segments the complex spectrum management function into separate tiered systems, each with defined access rights and protocols. This segmentation simplifies the overall system by dividing complex resource allocation into manageable hierarchical layers, where each tier operates independently according to its own rules while contributing to overall spectrum utilization efficiency.
