Engineering Contradiction Analysis
1Ease of manufacture
If traditional data collection methods are used in electrical power systems, then device compatibility and ease of installation are improved, but data collection efficiency and real-time monitoring capability deteriorate
Solution Approach 1:
The patent replaces traditional mechanical wiring-based data collection systems with wireless communication technology. Sensor nodes communicate with control nodes via wireless signals, eliminating the need for physical point-to-point wiring while maintaining ease of installation and significantly improving data collection efficiency and real-time monitoring capability.
2Measurement precision
If extensive wiring is implemented for data collection across the power system, then measurement precision and reliability are improved, but device complexity and installation cost increase
Solution Approach 1:
The patent replaces extensive physical wiring infrastructure with wireless communication networks. The mesh network topology allows multiple communication paths between nodes, maintaining measurement precision and data reliability while dramatically reducing system complexity and installation requirements.
Solution Approach 2:
The patent implements a dynamic mesh network where communication paths can adapt and reconfigure based on node availability and network conditions. This dynamic routing capability maintains data reliability without requiring fixed, complex wiring infrastructure.
3Reliability
If point-to-point wiring is used for each sensor connection, then communication reliability is improved, but ease of operation and scalability deteriorate
Solution Approach 1:
The patent implements a dynamic mesh network where communication paths can adapt and reconfigure based on node availability. This allows the system to maintain communication reliability while easily scaling by simply adding or removing nodes without reconfiguring the entire network infrastructure.
Solution Approach 2:
The patent creates a universal communication protocol and mesh network architecture that can accommodate multiple sensor types, control devices, and communication methods. This universal approach enables easy system expansion and operation across diverse power system configurations without requiring device-specific wiring.
