Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packet duplication is implemented to improve reliability, then data transmission reliability is improved, but system resource utilization deteriorates due to unnecessary duplicates
Solution Approach 1:
The patent implements dynamic adaptation of packet duplication based on real-time channel conditions and application requirements. The system transitions from static duplication to dynamic control by continuously monitoring channel quality indicators and application status, enabling the system to activate or deactivate duplication according to current network conditions, thus resolving the contradiction between reliability and resource utilization
Solution Approach 2:
The patent changes the parameter of duplication probability from fixed to variable based on channel conditions. By adjusting the duplication probability parameter dynamically according to channel quality metrics and application requirements, the system optimizes the balance between ensuring reliable transmission and avoiding unnecessary resource consumption
2Reliability
If fixed packet duplication is used to ensure robustness, then transmission robustness is improved, but available bandwidth deteriorates due to wasted resources
Solution Approach 1:
The patent applies partial duplication rather than full duplication in all cases. By selectively duplicating packets only when channel conditions indicate high risk of loss, the system provides sufficient robustness for critical transmissions while avoiding excessive duplication that would waste bandwidth resources
Solution Approach 2:
The system dynamically adjusts the duplication parameter based on channel quality indicators. When channel conditions are good, duplication is reduced or eliminated to maximize bandwidth availability. When channel conditions deteriorate, the duplication parameter increases to maintain robustness, thus resolving the contradiction between transmission robustness and available bandwidth
3Productivity
If adaptive replication control is implemented, then resource allocation is optimized, but control complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the system continuously monitors channel quality indicators and application status, then adjusts duplication decisions based on this feedback. This feedback loop enables adaptive resource allocation by using real-time information to control duplication, achieving efficient resource management while keeping the control mechanism manageable through systematic feedback processing
