Autonomous Vehicle Fleet for Water Area Safety Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lifeguard systems for recreational water areas face challenges in providing timely and comprehensive safety coverage, especially outside normal operating hours and in less populated areas, due to limited human lifeguard presence and physical limitations, leading to potential delays in detecting and responding to emergencies.
Innovation Solution
A recreational water area management system utilizing autonomous vehicles, such as unmanned aerial, ground, and water vehicles, to monitor and respond to safety events by receiving and analyzing information from sensors, coordinating rescue missions, and deploying resources like buoyancy devices and tracking buoys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If more lifeguards are deployed to monitor recreational water areas, then safety coverage and response capability are improved, but operational costs and resource requirements increase
Solution Approach 1:
The patent uses unmanned vehicles (aerial, ground, and water) as copies or substitutes for human lifeguards. These autonomous vehicles are equipped with sensors and communication systems to perform monitoring and emergency response functions, eliminating the need to deploy additional human lifeguards while maintaining or improving safety coverage.
Solution Approach 2:
The patent replaces the mechanical system of human lifeguards with an automated system comprising unmanned vehicles, sensors, and communication networks. This substitution allows for continuous monitoring without the physical limitations and costs associated with human personnel.
2Reliability
If lifeguards are stationed at fixed positions to monitor water areas, then monitoring coverage is improved, but response time to distant emergencies increases
Solution Approach 1:
The patent employs dynamic unmanned vehicles that can autonomously navigate and reposition themselves in response to detected emergencies. Unlike fixed-position lifeguards, these vehicles can quickly move to the location of incidents, significantly reducing response time while maintaining comprehensive monitoring coverage through their mobile sensor platforms.
Solution Approach 2:
The patent introduces aerial unmanned vehicles that operate in the air dimension above the water area, providing a new vantage point for monitoring. This three-dimensional monitoring capability allows vehicles to detect and respond to emergencies from overhead, bypassing the limitations of ground-based fixed positions and enabling faster access to distant locations.
3Reliability
If lifeguards work extended hours to cover non-operating periods, then safety coverage during off-hours is improved, but lifeguard availability and workforce requirements increase
Solution Approach 1:
The patent implements unmanned vehicles that can operate continuously without interruption, unlike human lifeguards who require rest periods and have limited working hours. These autonomous systems can maintain surveillance and emergency response capability around the clock, providing uninterrupted safety coverage during all operating hours including nighttime and weekends.
Solution Approach 2:
The patent uses self-powered unmanned vehicles that autonomously navigate, monitor, and respond to emergencies without requiring human operators to be physically present. These vehicles manage their own operation, including navigation to emergency locations and deployment of rescue equipment, eliminating the need for extended human work hours while maintaining continuous safety coverage.
4Reliability
If lifeguards manually search for drowning individuals in distant water areas, then rescue capability is improved, but detection speed and response efficiency decrease
Solution Approach 1:
The patent replaces manual lifeguard searching with automated sensor systems mounted on unmanned vehicles. These sensors, including optical and acoustic detectors, continuously scan the water area and can identify drowning individuals much faster than human lifeguards visually searching from a distance, significantly improving detection speed while maintaining rescue capability.
Solution Approach 2:
The patent uses aerial unmanned vehicles with overhead sensors to detect drowning individuals from above the water surface. This aerial perspective allows for rapid scanning of large water areas and detection of distress signals from drowning persons, greatly enhancing detection speed compared to lifeguards searching from ground level or water surface.

AI summary
A method and apparatus for managing a recreational water area. A recreational water area management system (212) comprises a water area manager (216). The water area manager (216) is configured to receive information (220) about a recreational water area from a group of autonomous vehicles (239), analyze the information (220) to identify an event (306), and coordinate the group of autonomous vehicles (239) to perform a mission (326) in the recreational water (204) area based on the event (306).
