Decompression Air Valve Assembly to Prevent Over-Inflation Bursting

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional air valve assemblies for inflatable products lack 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 uncontrolled air flow.

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 damage from excessive pressure and reducing component wear through controlled airflow.

Engineering Contradictions & Design Principles

VSEngineering 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 during air flow causing potential breakage

Engineering Contradiction:

Improveover-inflation protectionVSAvoidcomponent durability

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The decompression valve component is nested within the air valve component's receiving chamber. The decompression valve component includes a valve base received within the internal receiving chamber, creating a compact integrated structure that reduces component movement and vibration during operation.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

A limit portion is introduced as an intermediary element between the sealing portion and the outer body. This limit portion restrains the movement range of the sealing portion, preventing excessive shaking and rattling during air flow while still allowing the valve to open and close properly.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Extent of automation

If the decompression valve is designed to open freely when pressure exceeds decompression value, then automatic decompression function is improved, but the uncontrolled air flow causes components to shake and break

Engineering Contradiction:

Improveautomatic decompression functionVSAvoidcomponent stability

Core Design Contradiction:

Extent of automationVSReliability

Solution Approach 1:

The decompression valve uses air pressure feedback to automatically control opening and closing. When air pressure within the internal receiving chamber exceeds the decompression value, the sealing portion automatically moves to open state; when pressure drops below the decompression value, the sealing portion automatically returns to closed state, providing stable automated control.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The decompression valve component is designed to move dynamically in response to pressure changes. The sealing portion is supported for longitudinal movement between sealed and open states, allowing controlled motion that adapts to pressure conditions while the limit portion ensures this movement remains within safe boundaries.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If a combined air valve and decompression valve assembly is created, then both inflation and decompression functions are improved, but the device complexity increases

Engineering Contradiction:

Improvecombined inflation and decompression functionVSAvoidvalve assembly structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The air valve component and decompression valve component are merged into a single integrated assembly. The decompression valve component is received within the internal receiving chamber of the air valve component, allowing both inflation and decompression functions to be performed through one unified structure rather than separate components.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The valve assembly achieves multi-functionality by combining the air valve component for inflation/deflation control with the decompression valve component for automatic over-pressure protection. This universal design allows the single assembly to handle multiple functions that would traditionally require separate components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

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 service life of the valve components by minimizing shaking and rattling during air flow.

Implementation Method 1

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

Methodology Applied

Scientific EffectPressure differential: Pressure Gradient

Implementation Method 2

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

Methodology Applied

Scientific EffectPressure force: Pressure Gradient

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.
