Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmit power is increased to improve communication coverage and reliability, then signal quality and connection stability are improved, but inter-link interference between concurrent transmissions increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting transmit power levels based on interference conditions. The system monitors inter-link interference between concurrent transmissions and modifies power parameters in real-time to maintain communication reliability while reducing harmful interference effects.
Solution Approach 2:
The patent implements dynamics by making transmit power adjustable and adaptive rather than fixed. The power control mechanism dynamically responds to changing network conditions, allowing the system to optimize between reliability and interference mitigation based on current transmission scenarios.
2Object-generated harmful factors
If transmit power is reduced to minimize inter-link interference, then interference levels are controlled, but communication coverage and signal quality deteriorate
Solution Approach 1:
The patent uses parameter changes to adjust transmit power levels adaptively. By modifying power parameters based on monitored interference conditions and transmission requirements, the system prevents both excessive interference and insufficient coverage, maintaining optimal communication reliability.
Solution Approach 2:
The patent implements feedback mechanisms where the system monitors transmission conditions and interference levels, then uses this information to adjust transmit power accordingly. This closed-loop control ensures that power reduction for interference mitigation does not compromise communication reliability.
3Reliability
If maximum transmit power is allocated to a single link to ensure high-quality transmission, then transmission quality on that link is maximized, but available power for other concurrent links is reduced
Solution Approach 1:
The patent applies local quality by allocating different power levels to different links based on their specific requirements and conditions. Rather than uniform power distribution or single-link maximization, each link receives optimized power allocation tailored to its transmission quality needs and interference environment.
Solution Approach 2:
The patent implements dynamic power allocation where available power is distributed across concurrent links based on real-time conditions. The system can adjust power distribution dynamically to ensure high transmission quality on priority links while maintaining adequate power availability for other concurrent transmissions.
