Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional coverage methods are used to deploy information perception devices, then monitoring requirements of different target nodes can be met, but energy consumption increases and network life cycle shortens
Solution Approach 1:
The patent segments the information perception devices into different types (voltage monitoring devices, temperature monitoring devices, humidity monitoring devices, frequency monitoring devices) and deploys them selectively based on specific monitoring requirements of different target nodes, rather than deploying all device types at every node. This segmentation reduces unnecessary energy consumption while maintaining comprehensive monitoring coverage.
Solution Approach 2:
The patent applies local quality by deploying different types of information perception devices at different target nodes according to their specific monitoring needs. Each node receives only the device types necessary for its local requirements, optimizing energy usage while ensuring appropriate monitoring coverage for each location.
2Measurement precision
If all information perception devices are activated to ensure complete coverage, then monitoring accuracy is improved, but energy consumption increases and network life cycle shortens
Solution Approach 1:
The patent implements dynamic activation of information perception devices based on their residual energy levels and monitoring requirements. Devices are activated or deactivated dynamically according to current network conditions and energy availability, rather than maintaining all devices in a constant active state. This dynamic approach preserves monitoring accuracy while extending network life cycle.
Solution Approach 2:
The patent changes the operational state parameter of information perception devices based on residual energy thresholds. When devices fall below certain energy thresholds, their activation state is changed from active to dormant, and monitoring responsibilities are redistributed to other devices with sufficient energy. This parameter change maintains monitoring accuracy while conserving energy to extend network life cycle.
3Use of energy by moving object
If prioritized activation sorting is implemented based on residual energy, then energy efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service by enabling information perception devices to autonomously report their residual energy levels and monitoring capabilities to the control center. The control center automatically performs prioritized activation sorting based on received information, eliminating the need for complex manual scheduling or inter-device negotiation. This self-service approach improves energy efficiency while keeping the system relatively simple.
Solution Approach 2:
The patent uses feedback mechanisms where information perception devices continuously report their operational status and energy levels to the control center. The control center processes this feedback and adjusts activation priorities accordingly, implementing energy-efficient scheduling through simple feedback loops rather than complex centralized control algorithms.
