Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If power levels are increased to maximize transmission capacity, then communication throughput is improved, but inter-link interference increases
Solution Approach 1:
The patent dynamically adjusts power levels as a controllable parameter to optimize the trade-off between transmission capacity and interference. By determining specific power values for each link based on network conditions, the system achieves maximum throughput while maintaining interference control within acceptable limits.
Solution Approach 2:
The patent applies different power levels to different links individually rather than using a uniform power strategy. Each link's power is optimized based on its specific characteristics and interference environment, allowing local optimization that maximizes overall network performance while controlling interference at each link level.
2Object-generated harmful factors
If power levels are reduced to minimize inter-link interference, then interference control is improved, but power efficiency deteriorates
Solution Approach 1:
The system dynamically determines optimal power levels that balance interference control with power efficiency. Rather than uniformly reducing power, the patent adjusts each link's power parameter based on actual network conditions, achieving interference mitigation while maintaining acceptable power efficiency through intelligent parameter optimization.
3Productivity
If concurrent transmissions are enabled across multiple links, then network capacity is improved, but interference management complexity increases
Solution Approach 1:
The patent manages interference in concurrent transmissions by applying link-specific power control strategies. Each link is managed individually with tailored power levels, which simplifies the overall interference management complexity while enabling high network capacity through concurrent operations.
Solution Approach 2:
The system determines and configures power levels for multiple links in advance before concurrent transmissions begin. This preliminary power configuration reduces the complexity of real-time interference management during concurrent operations, as the power parameters are pre-optimized to minimize interference while maximizing network capacity.
