Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple concurrent transmissions are performed with different transmit powers, then network performance and signal quality are improved, but interference between links increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting transmit power levels for different concurrent transmissions based on interference conditions and signal quality requirements. The system determines multiple transmit powers corresponding to different links and selects appropriate power levels to balance signal quality improvement with interference control, resolving the contradiction between reliability and harmful factors.
2Reliability
If transmit power is increased to improve signal quality, then communication reliability improves, but power consumption increases
Solution Approach 1:
The system dynamically adjusts transmit power parameters based on actual communication conditions, channel state information, and interference levels. By optimizing power levels for each concurrent transmission rather than using maximum power continuously, the system improves signal quality when needed while minimizing overall power consumption.
Solution Approach 2:
The patent implements dynamic power control where transmit power is adjusted in real-time based on feedback about signal quality and interference conditions. This dynamic adaptation allows the system to use higher power only when necessary for reliable communication while reducing power consumption during periods of good channel conditions or low interference.
3Object-generated harmful factors
If power control is implemented for multiple concurrent links, then interference is reduced, but system complexity increases
Solution Approach 1:
The patent employs feedback mechanisms where the system monitors signal quality and interference levels for concurrent transmissions. Based on this feedback, the power control mechanism automatically adjusts transmit powers to minimize interference while maintaining communication reliability, managing system complexity through intelligent control rather than simplified hardware.
