Pressurized Cylinder Valve Cap with Segmented Grip and Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressurized fluid bottle valve protection caps lack a balance between providing sufficient protection and allowing easy manual and visual access, while also ensuring ergonomic handling and adequate shock resistance.
Innovation Solution
A protective cap with a central tubular portion housing the valve and a concentrically arranged annular portion connected via connecting arms, forming a manual grip wheel, which provides mechanical protection and allows for easy handling, while also displaying fluid quantity information and offering shock resistance through deformable design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a rigid cage structure is used to protect the valve, then protection capability is improved, but ease of operation deteriorates due to limited manual and visual access
Solution Approach 1:
The cap is divided into two concentric walls: a first wall forming a central tubular portion that houses the valve with spacing, and a second wall arranged concentrically around the first wall with an annular portion forming a hand-gripping wheel. This segmentation allows the valve to be protected within the inner tubular space while the outer annular portion provides manual access for handling the cylinder, thus resolving the contradiction between protection and ease of operation.
2Object-affected harmful factors
If a solid rigid cap structure is used, then protection capability is improved, but ease of operation deteriorates due to difficult handling
Solution Approach 1:
The cap structure is segmented into an inner first wall forming a tubular portion and an outer second wall with an annular hand-gripping wheel portion. The hand-gripping wheel provides a dedicated interface for manual handling operations such as rolling or tilting the cylinder, while the inner tubular portion maintains protection of the valve. This resolves the contradiction by providing specialized handling functionality without compromising protection.
3Object-affected harmful factors
If a rigid cap structure is used, then protection capability is improved, but reliability deteriorates due to reduced shock resistance
Solution Approach 1:
The cap is designed with a rigid structure that inherently provides shock resistance and impact absorption capabilities. The concentric dual-wall configuration with spacing between the first wall and the valve creates a protective zone that can absorb and distribute impact forces, protecting the valve from shock while maintaining overall structural integrity and reliability.

AI summary
The invention relates to a cap for protecting a valve of a cylinder of pressurised fluid which includes a rigid structure (2, 3) defining a protective space for a valve, said structure (2, 3) including a lower end (4) intended for being attached to the upper end of a cylinder of pressurised fluid, characterised in that the cap (1) comprises a first wall (2) forming a central tubular portion, said tubular portion extending between the lower end (4) and an open upper end (12) defining an opening (5) for accessing an inner space intended for containing a valve, the cap (1) also including a second wall (3) arranged concentrically with spacing around the first wall (2) and defining a protection area around the first wall (2).
