Aerosol Push Button Actuator for Low-Force Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol containers are difficult for individuals with limited physical strength, such as children and those with diseases like Parkinson, to operate due to the requirement of sufficient strength to activate the push button.
Innovation Solution
An aerosol container design featuring a push button positioned centrally on the main body, which requires minimal strength to operate, utilizing a simple mechanism without additional components or elongated handles, allowing operation with either the palm or thumb.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional push button mechanism is used, then the aerosol container can be operated, but it requires sufficient physical strength that excludes children and people with diseases like Parkinson
Solution Approach 1:
The push button is designed to move dynamically between pressed and released states, allowing users with limited strength to operate it by simply pressing rather than maintaining continuous force. The spring mechanism provides dynamic assistance by automatically returning the button to its initial position after pressing.
Solution Approach 2:
The force parameter required to operate the aerosol container is reduced by changing the mechanical advantage through the push button design. The button transforms a small pressing force into sufficient activation force for the valve mechanism, making operation accessible to children and people with physical limitations.
2Ease of operation
If additional components or elongated handles are added to facilitate operation, then ease of operation improves, but device complexity increases
Solution Approach 1:
The push button is merged with the cap structure, eliminating the need for separate elongated handles or additional operating components. The button is positioned on the longitudinal face of the cap, integrating the operating mechanism into the existing structure rather than adding external aids.
Solution Approach 2:
The cap serves multiple functions: it closes the nozzle opening and provides the push button for actuation. This multi-functionality eliminates the need for separate operating handles, maintaining simplicity while improving ease of operation for users with limited strength.

AI summary
The present invention is an aerosol container with an easy-to-operate push button which requires minimal strength to operate push button and hence operable by children and people having less strength. Aerosol container includes a main body, a nozzle, a pipe and an actuating mechanism. Actuating mechanism includes a valve operable by a push button and a release spring. Valve is in connection with an internal body portion of pipe and selectively permits flow of aerosol from main body to nozzle upon actuation of push button disposed in-line with valve, transverse to pipe and externally of main body. As push button is disposed centrally of main body, children or people with less strength or suffering from illness like Parkinson are easily able to push the push button.
