Unitary Elastomer Venting Valve with Integrated Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing venting valves require multiple components and complex assembly, leading to high assembly costs and inadequate sealing due to the need for separate elastomer caps and support components, which also occupy significant mounting space.
Innovation Solution
A venting valve design that generates closure tension on the venting slot through internal forces, such as radial or axial deformation, allowing for a simple and cost-effective assembly with a single unitary elastomer material, ensuring reliable sealing without the need for additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple components (support component and elastomer cap) are used to form the venting valve, then the sealing function can be achieved, but the assembly expenditure and device complexity increase
Solution Approach 1:
The patent merges the support component and elastomer cap into a single integrated venting valve component. The venting valve comprises a valve body made of elastomer material with a securing part for mounting and a venting slot, eliminating the need for separate support components and reducing assembly complexity while maintaining sealing functionality.
2Reliability
If multiple components are assembled to form the venting valve, then the sealing function is attempted, but the assembly time and cost increase
Solution Approach 1:
The venting valve is designed as a single integrated component combining the mounting function (securing part) and sealing function (valve body with venting slot) into one elastomer piece, eliminating multiple assembly steps and reducing assembly expenditure.
3Reliability
If separate elastomer cap and support component are used, then mounting is attempted, but the mounting space required increases
Solution Approach 1:
The securing part and valve body are merged into a single integrated component, reducing the overall mounting space required compared to separate components that would need individual mounting areas and connection interfaces.
4Ease of manufacture
If elastomer caps are used for sealing, then the venting valve can be formed, but the sealing performance is insufficient
Solution Approach 1:
The patent modifies the geometric parameters of the venting slot and the elastic properties of the elastomer material to optimize sealing performance. The closure tension acting on the venting slot ensures proper sealing, and the radial elastic deformation of the securing part enhances the sealing action while maintaining ease of manufacture.
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 design achieves reliable sealing with reduced assembly complexity and space requirements, maintaining a secure attachment and sealing function across varying pressure conditions.
Implementation Method 1
it is formed in a preferred embodiment by a radial elastic deformation of the securing part of the venting valve
Implementation Method 2
The insertion part is elastically deformed in the bore such that the axial force that serves for generating the closure action is generated
Data Source
AI summary
A venting valve has a securing part and a valve body connected to the securing part and provided with at least one venting slot. A closure tension acts on the venting slot and is caused by a force generated within the venting valve after mounting. The venting valve is made of a unitary elastomer material.
