Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional transceivers communicate over large bandwidths, then bandwidth utilization is improved, but synchronization errors and hardware limitations worsen
Solution Approach 1:
The patent divides the large bandwidth into multiple component carriers (CCs), each with manageable bandwidth. This segmentation allows the system to utilize large total bandwidth while maintaining synchronization accuracy for each individual carrier, thereby resolving the contradiction between bandwidth utilization and synchronization reliability.
Solution Approach 2:
The patent implements adaptive communication configuration that dynamically adjusts the number and bandwidth of component carriers based on distance and channel conditions. This dynamic adaptation optimizes the balance between bandwidth utilization and synchronization performance for varying operational scenarios.
2Productivity
If very large bandwidths are used, then data rate is improved, but sampling time requirements and converter performance become bottlenecks
Solution Approach 1:
By segmenting the large bandwidth into multiple component carriers with moderate individual bandwidths, the system achieves high aggregate data rate while keeping sampling time requirements and converter specifications within practical limits for each carrier.
Solution Approach 2:
The patent changes the operational parameters by using multiple carriers with adjusted bandwidth and frequency settings. This allows the system to achieve high data rates through carrier aggregation while maintaining manageable sampling rates and converter performance for each individual carrier.
3Quantity of substance
If carrier aggregation is used to utilize Terahertz spectrum, then bandwidth utilization is improved, but device complexity increases
Solution Approach 1:
The adaptive communication configuration dynamically determines the optimal number and bandwidth of component carriers based on distance and channel conditions. This dynamic approach simplifies device complexity by automatically adapting to conditions rather than requiring complex manual configuration, while still achieving efficient Terahertz spectrum utilization.
Solution Approach 2:
The system performs self-configuration by automatically determining the appropriate carrier aggregation parameters based on measured distance and channel statistics, reducing the need for external configuration complexity while maximizing spectrum utilization.
