Pressurized Fluid Container Stabilizing Structure Prevents Rolling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pressurized gas containers with pivoting attachment devices face instability when folded, leading to potential damage from weight stress and rolling issues, particularly on uneven surfaces, which complicates their use in emergency situations.
Innovation Solution
A pressurized fluid container design featuring a mobile attachment device with a stabilizing structure that projects beyond the cylindrical body when folded, preventing rolling by providing a stable rim to rest on surfaces, thus ensuring stability and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the attachment device is folded to conform to the cover shape, then storage and handling are facilitated, but the container becomes unstable and can roll on surfaces
Solution Approach 1:
The stabilizing structure extends the attachment device in a new spatial dimension perpendicular to the cover surface, creating a third dimension of support. This dimensional extension transforms the folded attachment device from a purely conformal element into a multi-functional component that provides both compact storage and rolling prevention through its protruding stabilizing structure.
2Adaptability or versatility
If the attachment device is unfolded for hanging or flat positioning, then the container can be hung from bed rails or laid flat, but the high center of gravity causes instability and stress on the arms
Solution Approach 1:
The stabilizing structure preemptively counteracts the rolling tendency by providing a geometric constraint before rolling can occur. The perpendicular rim creates a physical barrier that prevents the container from rotating on its cylindrical body, effectively neutralizing the instability caused by the high center of gravity in horizontal positioning.
3Shape
If the attachment device arms are positioned on either side of the cover when folded, then the device conforms to the cover shape, but the cylindrical container can easily roll on surfaces
Solution Approach 1:
The stabilizing structure introduces asymmetry to the otherwise symmetric folded attachment device. By extending one or more arms perpendicular to the cover surface with a rim, the device creates an asymmetric geometric profile that prevents rolling while maintaining the symmetric conformal appearance when viewed from the front or back.
