Decompression air valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air valve assemblies for inflatable products do not provide an automatic decompression function, leading to potential bursting when over-inflated, and existing combinations of air and decompression valves often result in components shaking or breaking due to inadequate sealing and response to pressure changes.
Innovation Solution
A combined inflation and decompression valve assembly with a decompression valve component that automatically opens when internal pressure exceeds a set value, allowing air to escape while preventing excessive decompression and minimizing component wear through precise sealing and spring mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simple decompression valve is added to provide automatic decompression function, then over-inflation protection is improved, but the valve components shake and rattle due to air flow when open
Solution Approach 1:
The patent applies the dynamics principle by making the decompression valve component movable rather than fixed. The valve component is supported for longitudinal movement within the internal receiving chamber, allowing it to dynamically respond to pressure changes. When air pressure exceeds the decompression value, the valve component automatically moves to an open state to release pressure, and returns to a sealed state when pressure normalizes, preventing shaking and rattling while maintaining durability.
Solution Approach 2:
The patent uses an intermediary mechanism (the movable valve component acting as a mediator) between the air chamber and the external environment. This intermediary component controlledly mediates the air flow based on pressure conditions, opening to decompress when needed and sealing when pressure is normal, thereby protecting other components from direct exposure to high-velocity air flow that would cause shaking and damage.
2Reliability
If the decompression valve remains open to allow air escape, then decompression function is improved, but the valve does not automatically close when pressure reduces
Solution Approach 1:
The patent implements feedback through the pressure-responsive movable valve component. The valve component continuously monitors the air pressure in the air chamber and automatically adjusts its state based on feedback from pressure changes. When pressure exceeds the decompression value, the valve opens; when pressure reduces to normal levels, the valve automatically closes, providing both effective decompression and automatic response without manual intervention.
3Device complexity
If conventional air valve assemblies are used without decompression function, then device simplicity is maintained, but the product may burst when over-inflated
Solution Approach 1:
The patent applies the merging principle by combining the decompression valve component with the air valve assembly into a single integrated structure. The decompression valve component is received within the internal receiving chamber of the air valve assembly, merging safety decompression functionality with the existing inflation/deflation valve structure. This integration provides over-inflation protection without requiring a completely separate decompression system, balancing enhanced safety with reasonable structural complexity.
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 valve assembly effectively prevents over-inflation by automatically decompressing when pressure exceeds a set value, reducing the risk of bursting and extending the lifespan of the valve components by minimizing exposure to flowing air.
Implementation Method 1
A limit portion is operably coupled with the sealing portion. When air pressure within the internal receiving chamber is greater than a decompression value, the sealing portion and the limit portion move relative to each other, and the sealing portion abuts the limit portion to move the decompression valve component from the sealed state to the open state.

AI summary
A valve assembly configured for use with an inflatable product, such as a mattress, chair, pool, spa, float, or another suitable inflatable product. The valve assembly includes a first valve component that serves as an opening for inflation and/or deflation of the inflatable product, and a second valve component that serves as an opening for deflation or decompression of the inflatable product.
