Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If network energy saving management is implemented, then energy consumption is reduced, but network performance deteriorates
Solution Approach 1:
The patent implements dynamic energy saving management where network nodes adjust their operating states based on real-time network conditions. The management unit dynamically determines energy saving modes and scope information, allowing the system to adapt between energy saving and performance maintenance based on current traffic patterns and network status, thus resolving the static trade-off between energy consumption and network performance
Solution Approach 2:
The system changes operational parameters of network nodes by sending energy saving control messages that modify working states, power levels, and operational modes. These parameter adjustments allow nodes to operate in optimized states that balance energy consumption with performance requirements, transforming fixed performance characteristics into adjustable parameters
2Loss of energy
If energy saving operations are applied to all network nodes, then overall energy saving increases, but network performance loss increases
Solution Approach 1:
The patent applies energy saving measures selectively to specific network nodes based on their individual characteristics, traffic patterns, and performance requirements. The management unit determines scope information that identifies which nodes should undergo energy saving operations, allowing different parts of the network to have different energy saving intensities, thus preventing uniform application from causing excessive overall performance loss
Solution Approach 2:
The network is segmented into different groups based on energy saving priority and performance sensitivity. The management unit divides the network into target nodes for energy saving and non-target nodes that maintain normal operation, allowing energy saving operations to be applied in a segmented manner that balances overall energy reduction with localized performance maintenance
3Loss of energy
If energy saving mode is adjusted to improve energy saving effect, then energy consumption decreases, but network latency increases
Solution Approach 1:
The system dynamically adjusts energy saving modes based on real-time network conditions and service requirements. When latency-sensitive services are detected or network traffic increases, the management unit modifies energy saving parameters to maintain performance. This dynamic adjustment ensures that energy saving operations do not cause excessive latency by adapting the degree of energy saving to current operational demands
