Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If centralized control is performed on the system operation of the network, then control efficiency is improved, but vulnerability to natural disasters increases and damage magnitude is increased
Solution Approach 1:
The patent segments the centralized network control into multiple distributed control nodes organized in a hierarchical structure. The network is divided into multiple regions, each with its own control layer that can operate autonomously. This segmentation allows the system to maintain control efficiency through localized decision-making while reducing vulnerability to natural disasters, as failures in one region do not propagate system-wide.
Solution Approach 2:
The patent introduces a hierarchical dimension to the control architecture, creating multiple levels of control (local, regional, and global coordination layers). This dimensional transformation allows the system to combine the benefits of centralized coordination at higher levels with the resilience of distributed autonomy at lower levels, effectively resolving the contradiction between control efficiency and disaster vulnerability.
2Stability of the object's composition
If centralized control is performed on the system operation of the network, then system coordination is improved, but recovery time after disaster is prolonged
Solution Approach 1:
By segmenting the control system into autonomous regional units, the patent enables parallel recovery operations across different regions. Each control node can independently initiate and execute recovery procedures without waiting for centralized approval, dramatically reducing overall recovery time while maintaining system coordination through predefined communication protocols between nodes.
Solution Approach 2:
The patent implements preliminary configuration of backup control nodes and pre-established communication protocols that enable automatic failover and coordinated recovery actions. When a disaster occurs, pre-configured recovery procedures are automatically activated at distributed nodes, eliminating the time delay associated with centralized decision-making during crisis recovery.
3Productivity
If networks are highly integrated in physical space and cyberspace, then efficiency of functions and services is improved, but vulnerability to simultaneous failures increases
Solution Approach 1:
The patent segments the highly integrated network into isolated but interconnected regional units with autonomous control capabilities. This segmentation maintains the efficiency benefits of network integration within each region while creating firewalls that prevent simultaneous failures from propagating across the entire system. Each segment can continue operating independently even when other segments experience failures.
