Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for detecting water irrigation restriction violations, such as using drones and satellites, are costly and lack sufficient spatial and temporal resolution, making it difficult for governmental jurisdictions to effectively enforce water conservation measures in large geographic areas.
Innovation Solution
A geostationary satellite system that collects soil surface moisture and rain data multiple times a day with high spatial resolution, coupled with a processor to determine violations based on stored irrigation restrictions and send notifications to authorities, allowing for routine monitoring and timely detection of irrigation excesses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If drones are used to patrol geographical regions for water irrigation restriction violations, then detection capability is improved, but cost becomes prohibitive due to manpower and equipment requirements
Solution Approach 1:
The patent uses satellite imagery as a remote copy or representation of the ground conditions, allowing authorities to detect irrigation violations without physically deploying drones or personnel to the field. The satellite images serve as a cheaper alternative copy that provides sufficient detection capability for enforcement purposes
Solution Approach 2:
The patent replaces the mechanical drone patrol system with a satellite-based optical sensing system. Instead of using mechanical vehicles (drones) to physically patrol and detect violations, the system uses satellite imagery processed through image analysis algorithms to achieve the same detection function at lower cost
2Device complexity
If satellites are used for aerial monitoring of water irrigation restrictions, then cost becomes economically viable, but spatial resolution is too coarse and observation frequency is insufficient
Solution Approach 1:
The patent changes the temporal parameter of satellite observation by utilizing multiple satellite passes throughout the day to capture images at different times. This increased observation frequency compensates for the coarse spatial resolution by providing more opportunities to detect wet soil conditions that indicate irrigation violations
Solution Approach 2:
The system performs preliminary analysis of satellite imagery to identify potential violation areas before ground enforcement actions are taken. By analyzing multiple satellite passes and identifying patterns of wet soil, the system can proactively flag areas for investigation, improving detection effectiveness despite resolution limitations
3Measurement precision
If satellite observation frequency is increased to detect wet soil before drying, then detection accuracy is improved, but data processing complexity increases
Solution Approach 1:
The patent extracts only the relevant features from satellite images that indicate irrigation violations, such as wet soil patterns and irrigation infrastructure. By focusing on specific extracted features rather than processing entire high-resolution images, the system maintains detection accuracy while reducing overall data processing complexity
Solution Approach 2:
The patent segments the geographic region into smaller zones or areas of interest based on irrigation district boundaries and known agricultural areas. This segmentation allows the system to process and analyze only relevant portions of satellite imagery, reducing data processing complexity while maintaining detection accuracy in target areas

AI summary
A water irrigation restriction violation system includes a geostationary satellite to collect soil surface moisture data and rain data throughout a given day for a geographic region. A processor and a memory coupled to the processor are configured to store water irrigation restrictions for governmental jurisdictions for the geographic region, receive the soil surface moisture data and rain data from the geostationary satellite, and determine a water irrigation restriction violation based upon the stored water irrigation restrictions and the received soil surface moisture data and rain data. A violation notification is then sent to a corresponding governmental jurisdiction for the determined water irrigation restriction violation.
