Engineering Contradiction Analysis
1Measurement precision
If professional precipitation monitoring devices are deployed to monitor precipitation in a region, then measurement precision is improved, but device complexity and deployment cost increase
Solution Approach 1:
The patent replaces traditional mechanical precipitation monitoring devices with a wireless sensing system that uses radio wave propagation characteristics to detect precipitation. The access network function utilizes existing wireless communication infrastructure to perform sensing measurements, eliminating the need for dedicated mechanical rain gauges and monitoring hardware deployment.
Solution Approach 2:
The access network function is designed to perform multiple functions including both communication and precipitation sensing. By integrating sensing capabilities into existing access network nodes, the system achieves multi-functionality, allowing these nodes to serve dual purposes: data communication and environmental monitoring, thereby reducing overall system complexity.
2Measurement precision
If professional precipitation monitoring devices are deployed to monitor precipitation in a region, then measurement precision is improved, but the deployment scale is limited due to high investment requirements
Solution Approach 1:
The patent uses existing access network functions as substitutes for dedicated precipitation monitoring devices. Instead of deploying new specialized hardware, the system leverages and repurposes existing wireless network infrastructure, effectively copying the monitoring function onto available network nodes, thereby enabling large-scale deployment without additional hardware investment.
Solution Approach 2:
Access network functions are designed to provide both communication services and precipitation sensing capabilities. This multi-functionality allows the same infrastructure to serve multiple purposes, significantly increasing deployment scalability while avoiding the high costs associated with deploying dedicated monitoring devices across extensive areas.
3Device complexity
If wireless sensing technology is used to provide precipitation monitoring service, then device complexity is reduced, but measurement precision may deteriorate
Solution Approach 1:
The system implements a feedback mechanism where the access network function continuously performs sensing measurements and reports precipitation data to the network function. This feedback loop enables real-time monitoring and allows for dynamic adjustment of measurement parameters, maintaining measurement precision while using simplified wireless sensing technology.
Solution Approach 2:
The patent utilizes changes in radio wave propagation parameters (such as signal attenuation, phase shift, or time delay) caused by precipitation to detect and measure precipitation amounts. By monitoring these parameter variations in the wireless signal transmission, the system achieves accurate precipitation measurement using simple wireless sensing components without complex dedicated instrumentation.
