Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional static energy-saving techniques are used, then energy consumption is reduced, but network performance and user experience deteriorate due to inability to adapt to fluctuating traffic loads
Solution Approach 1:
The patent implements dynamic cell switching policies that automatically adjust based on real-time traffic load conditions. The system transitions from static energy-saving configurations to dynamic adaptation by continuously monitoring traffic patterns and adjusting cell activation states, thereby resolving the contradiction between energy conservation and adaptability to fluctuating demands.
Solution Approach 2:
The system employs feedback mechanisms by monitoring traffic load metrics and using this information to dynamically adjust cell switching decisions. The feedback loop enables the network to respond to changing traffic conditions while maintaining energy efficiency, addressing the contradiction between static energy-saving approaches and the need for adaptive response to traffic variations.
2Reliability
If more cells are kept active to improve network performance, then user experience improves, but energy consumption increases
Solution Approach 1:
The patent implements dynamic cell switching policies that automatically adjust based on real-time traffic load conditions. The system transitions from static energy-saving configurations to dynamic adaptation by continuously monitoring traffic patterns and adjusting cell activation states, thereby resolving the contradiction between energy conservation and adaptability to fluctuating demands.
Solution Approach 2:
The system changes the operational state parameter of cells dynamically based on traffic conditions. By adjusting the activation state (on/off) of cells according to real-time traffic load thresholds, the system optimizes the balance between maintaining sufficient network coverage for reliability and minimizing energy consumption during low-traffic periods.
3Use of energy by moving object
If dynamic cell switching policies are implemented, then energy efficiency improves, but system complexity increases
Solution Approach 1:
The patent divides the network into multiple cell groups that can be independently managed with specific switching policies. This segmentation allows the complex energy optimization problem to be broken down into manageable cell-level decisions, reducing overall system complexity while maintaining energy efficiency benefits through localized policy implementation.
