Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unattended swimming pools pose a significant safety hazard due to unauthorized or accidental entry, with existing safety measures like fences and covers being ineffective when not secured, and there is a need for a reliable, automated system that alerts homeowners to potential emergencies.
Innovation Solution
A swimming pool safety system utilizing infrared barrier sensors, water pressure sensors, and motion detectors, activated by a digital control panel with a personalized security code, triggers a dual-alert protocol with an audible alarm and high-intensity LED strobe light upon unauthorized entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional safety measures like fences and covers are used, then physical barrier protection is provided, but they are not always effective when not secured or left open
Solution Approach 1:
The patent replaces mechanical safety barriers (fences and covers) with an automated sensor-based detection system. Infrared barrier sensors, water pressure sensors, and motion detectors automatically monitor the pool area and trigger alarms without requiring manual operation or physical barrier maintenance, thus eliminating the reliability-ease of operation contradiction.
Solution Approach 2:
The safety system operates autonomously by continuously monitoring the pool area through multiple sensors and automatically triggering alarm sequences when unauthorized access is detected. The system requires no human intervention to function, self-regulating safety monitoring and alert generation, which resolves the contradiction by making the system both reliably effective and operationally simple.
2Reliability
If multiple sensors and alert mechanisms are deployed, then detection reliability is improved, but system complexity increases
Solution Approach 1:
The patent divides the safety monitoring function into separate specialized sensors: infrared barrier sensors for perimeter detection, water pressure sensors for water disturbance detection, and motion detectors for area monitoring. Each sensor handles a specific detection task, improving overall reliability while managing complexity through functional segmentation rather than a single complex system.
Solution Approach 2:
The patent combines multiple independent alert mechanisms (audible alarm and visual strobe light) that work together to provide comprehensive notification. This merging of complementary functions enhances detection reliability and alert effectiveness while maintaining manageable system complexity through coordinated operation of standardized components.
3Loss of time
If automated alert mechanisms are activated, then response time is reduced, but energy consumption increases
Solution Approach 1:
The safety system operates in periodic cycles, with sensors continuously monitoring and alert mechanisms activated only when breaches are detected. The infrared, pressure, and motion sensors use periodic detection cycles rather than continuous high-power operation, reducing energy consumption while maintaining rapid response capability when needed.
Solution Approach 2:
The system uses high-visibility visual alert mechanisms including LED strobe lights that provide rapid visual notification with lower energy consumption compared to continuous illumination. The visual alerts use intense light emission only during alarm events, optimizing the balance between rapid response time and energy efficiency.

AI summary
A swimming pool safety system is provided. The system is designed to prevent unattended swimming pool accidents through continuous monitoring and automated alert mechanisms. The system comprises multiple layers of protection, including infrared barrier sensors that project horizontal beams to detect perimeter breaches, water pressure sensors that identify disturbances caused by sudden water displacement, and motion detectors that monitor movement around the pool area. These sensors are configured to reduce false alarms and ensure comprehensive coverage. When a breach is detected, the system activates a dual-alert protocol, which includes a 100- to 120-decibel audible alarm emitted through weatherproof speakers and a high-intensity LED strobe light for visual alerts. The system is controlled via a waterproof digital control panel requiring a personalized security code, which allows users to activate, deactivate, and configure settings.
