Fluid Bladder Alert Mat for Child Proximity Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child protective systems, such as door latch systems, are ineffective in preventing children from accessing hazardous areas as they can be easily opened by children, allowing unintended access to stored contents.
Innovation Solution
A proximity alert system that includes an alert mat with a fluid bladder and horn configuration, which sounds an audible alert when pressure is applied, notifying caregivers of a child's proximity to a selected location without requiring power, allowing placement in various locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional door latch system is used to protect hazardous areas, then the system provides basic closure functionality, but the system can be easily opened by children allowing unintended access
Solution Approach 1:
The patent replaces the purely mechanical door latch system with a hybrid system that incorporates acoustic sensing technology. The alert mat uses acoustic sensors to detect the characteristic sounds of a child approaching or interacting with the hazardous area, converting acoustic energy into electrical signals that trigger an alert. This substitution transforms the passive mechanical barrier into an active monitoring system that provides reliable detection without requiring physical intervention from the child to activate.
Solution Approach 2:
The patent introduces an intermediary alert mat positioned between the child and the hazardous area. This mat serves as a mediator that detects the child's presence through acoustic signals and communicates this information to the caregiver via an alert. The intermediary device bridges the gap between the child's actions and the caregiver's awareness, providing timely notification without requiring direct contact with the hazardous area or complex installation modifications.
2Reliability
If an advanced alert system is implemented to detect child proximity, then the safety effectiveness is improved, but the device complexity and installation requirements increase
Solution Approach 1:
The alert mat is designed as a self-service device that requires minimal installation effort. It simply needs to be placed on the floor in front of the hazardous area and connected to a power source and alert indicator. The system automatically detects acoustic signals and triggers alerts without requiring complex configuration, calibration, or integration with existing home systems. This self-service approach maintains high safety effectiveness while minimizing installation complexity.
Solution Approach 2:
The patent designs the alert mat as a universal device that can be applied to various hazardous areas throughout the home, such as cupboards, kitchens, and bathrooms. The same basic unit can protect different areas by simply changing its location, eliminating the need for custom-designed solutions for each hazard. This multi-functionality reduces overall system complexity while maintaining reliable protection across multiple locations.
3Measurement precision
If a power-dependent electronic monitoring system is used to detect child proximity, then the detection accuracy is improved, but the installation flexibility and portability are reduced
Solution Approach 1:
The patent incorporates a balloon component that can be inflated to provide structural support and housing for the electronic components. This pneumatic element allows the device to maintain its shape and protect sensitive electronics while remaining lightweight and easily relocatable. The balloon-based structure provides a flexible foundation that can be set up in various locations without requiring permanent installation or heavy framing.
Solution Approach 2:
The alert mat utilizes a flexible, thin-film construction that can be easily placed on different floor surfaces and removed for relocation. This flexible shell design allows the device to adapt to various placement locations while protecting the internal electronic components. The thin-film structure maintains detection accuracy while enabling portability and installation flexibility across different areas of the home.

Function Achieved in This Case
Effectively prevents children from accessing hazardous areas by alerting caregivers of their proximity, enhancing the safety of child protective systems without the need for power or complex installation.
Implementation Method 1
a fluid bladder configured to transmit pressure to the control system in response to pressure applied to the alert mat
Data Source
AI summary
An alert system includes a bladder having an interior area to hold a gas or a liquid; a control system in communication with the bladder; an alert device in communication with the bladder; pressure applied to the bladder causes the gas or the liquid to pass to the control system; and the gas or the liquid causes the alert device to provide an alert based on a command from the control system.
