Solution Overview
Problem
There is a significant number of drowning deaths, particularly among children in swimming pools, due to the inability of existing systems to accurately identify potential drowning situations in time and provide adequate safety measures.
Innovation Solution
A camera system utilizing multiple camera types, including IR and video, to monitor a three-dimensional space, identify movement patterns, and deploy preventative measures such as alarms and notifications to emergency services if a potential drowning scenario is detected, ensuring timely intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple camera types (IR and video) are used to monitor the pool area, then the detection precision of drowning situations is improved, but the device complexity increases
Solution Approach 1:
The monitoring system is divided into multiple specialized camera units (IR cameras for thermal detection, video cameras for visual monitoring) that each perform specific detection functions. This segmentation allows each component to be optimized for its specific purpose while collectively achieving high detection precision for drowning situations.
Solution Approach 2:
The camera system is designed to perform multiple functions: IR cameras detect body heat signatures, video cameras capture visual images, and the system integrates both data streams for comprehensive monitoring. This multi-functionality approach allows a single integrated system to achieve high detection precision across different detection modalities.
2Reliability
If the system provides multiple safety measures (audible alarm, visual alarm, notifications to owner and EMS), then the reliability of drowning prevention is improved, but the device complexity increases
Solution Approach 1:
The system pre-configures multiple alerting mechanisms (audible alarms, visual alarms, notification systems) before a drowning incident occurs. When detection is triggered, these pre-configured systems immediately activate, ensuring reliable and rapid response without requiring complex real-time decision-making about which safety measure to deploy.
Solution Approach 2:
The system implements a feedback loop where detection results automatically trigger appropriate safety measures. The notification system provides feedback to both pool owners and emergency services, creating a multi-layered reliability mechanism where multiple independent alert paths ensure that help is summoned regardless of system failures in individual components.
3Measurement precision
If the system monitors three-dimensional space and identifies movement patterns to detect drowning, then the detection precision is improved, but the loss of time for processing increases
Solution Approach 1:
The system employs periodic scanning and frame-based analysis of video and IR footage, processing images at standardized intervals rather than continuously analyzing every pixel change. This periodic action maintains detection precision by systematically examining the three-dimensional space while reducing computational overhead and processing time compared to continuous real-time analysis.
