Wearable Emergency Alert Balloon Automatic Inflation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency alert devices do not have a mechanism for automatic release of a balloon to alert viewers to an emergency, which delays attention being drawn to the user in need.
Innovation Solution
A wearable belt-based emergency alert apparatus with a housing, gas tank, tubing, balloon, and valve that allows for automatic inflation and release of a balloon with alert indicia, utilizing a pull cord to actuate the valve and detach the balloon from the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a belt-based alert device with gas tank and balloon is used, then the alert function is provided, but the device complexity increases
Solution Approach 1:
The balloon is nested within the housing and contains the alert indicium inside it. The gas tank is positioned in the interior space of the housing. This nesting arrangement consolidates multiple components into a compact integrated unit, providing the alert function while managing device complexity through spatial organization.
Solution Approach 2:
The belt serves multiple functions: it wears around the user's waist to position the device and also provides a pull cord mechanism to actuate the valve. This multi-functionality reduces the need for separate components, addressing the alert function requirement while controlling device complexity.
2Loss of time
If automatic release mechanism is added to the device, then the response time is improved, but the device complexity increases
Solution Approach 1:
The balloon is pre-positioned within the housing adjacent to the opening, and the gas is pre-stored in the gas tank. When the valve is actuated, the balloon immediately inflates and moves outwardly through the opening without requiring additional assembly or preparation steps. This preliminary positioning enables rapid response while using a simple mechanical valve mechanism rather than complex automatic sensors.
Solution Approach 2:
The balloon's expansion automatically pushes it outwardly through the opening without requiring separate ejection mechanisms. The inflated balloon self-propels out of the housing using the gas pressure from the tank, eliminating the need for motors, solenoids, or other complex automatic release mechanisms.
3Illumination intensity
If the balloon is made expandable with alert indicia, then the visibility is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The alert indicium is applied specifically to the portion of the balloon that will be externally visible when inflated. This localized application of visual elements focuses manufacturing precision only where needed for visibility, rather than requiring uniform precision across the entire balloon structure.
Solution Approach 2:
The patent uses alert indicium that can include colors or visual changes to enhance visibility. By relying on color and visual properties rather than complex structural features, the manufacturing precision requirements are reduced while maintaining high visibility for the alert function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables immediate and visible alerting of observers to emergencies, such as drowning, by automatically releasing a helium-filled balloon with alert messages or symbols, ensuring timely assistance.
Implementation Method 1
The quantity of gas is contained in the gas tank under pressure
Implementation Method 2
The balloon comprises a stretchable material such that the balloon expands when the balloon is filled with the gas
Implementation Method 3
a device which attaches via a belt to a user and which is capable of filling a balloon having visual components with gas so that the balloon floats in the air
Data Source
AI summary
An emergency alert assembly for alerting people to a drowning or other emergency near an individual wearing the apparatus includes a belt and an alert device attached to the belt. The alert device includes a balloon and a gas tank which selectively fills the balloon with gas that is less dense than air. When filled with the gas, the balloon moves out of the housing and serves to indicate a location of an emergency such as a drowning.
