Valve Pusher Protective Element for Pressurized Fluid Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging devices for pressurized fluids experience issues such as shocks, friction, and premature wear due to the movement of valve pushers, which can lead to contamination and damage to the sealing zones.
Innovation Solution
A packaging device with a valve pusher that includes a protective element made from a material with lower hardness than the body, designed to absorb shocks and reduce friction when interacting with the valve, thereby minimizing damage and ensuring a secure seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a valve pusher is used to actuate the valve opening, then the fluid transfer pipe can be connected to the container, but shocks and friction occur causing premature wear and contamination
Solution Approach 1:
A protective element is introduced as an intermediary component between the valve pusher and the valve. This protective element absorbs the shocks and reduces friction during valve actuation, preventing direct contact between the hard valve pusher and the valve surface, thereby eliminating contamination risks while maintaining reliable fluid connection.
Solution Approach 2:
The protective element is pre-installed on the valve pusher before actuation. It provides beforehand cushioning by absorbing impact energy during valve opening/closing operations, preventing shocks from reaching the valve and fluid channels, thus avoiding premature wear and particle generation before they can occur.
2Strength
If the valve pusher body is made from hard material, then durability is improved, but friction and shock damage to valve components increases
Solution Approach 1:
The valve pusher is designed with non-uniform material properties: the body is made from hard material for structural durability, while the protective element at the contact surface is made from soft material to reduce friction and shock. This local quality differentiation allows the hard body to maintain strength while the soft protective element prevents contamination.
Solution Approach 2:
The valve pusher assembly combines two different materials: a hard material for the body providing structural integrity and durability, and a soft material for the protective element providing low-friction contact. This composite material approach resolves the contradiction between needing hardness for durability and softness to prevent friction damage and contamination.
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
The use of a protective element with lower hardness effectively reduces shocks and friction, minimizing wear and preventing contamination, thus enhancing the reliability and longevity of the packaging device.
Implementation Method 1
the at least one protective element being intended to come into contact at least in part with the valve when the opening of said valve is actuated
Implementation Method 2
The force applied to push the valve will cause shocks on the surface of the valve(s)... Vibrations of the inner valve, and/or friction in this second channel can also be induced
