Nested Air Hose Assembly for Combined High- and Low-Pressure Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air systems require separate hose assemblies for high-pressure (HP) and low-pressure (LP) air applications, leading to complexity and increased costs due to the need for multiple hoses for various tasks.
Innovation Solution
A combined air system utilizing a single hose assembly with a manifold, where a high-pressure hose is disposed partially within a low-pressure hose, allowing both HP and LP air to be provided through the same hose assembly, simplifying the setup and reducing the number of hoses needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate hose assemblies are used for high-pressure and low-pressure air applications, then each hose can be optimized for its specific pressure requirement, but the system complexity and the number of hoses needed increase
Solution Approach 1:
The patent combines separate high-pressure and low-pressure hose assemblies into a single integrated hose assembly. The hose assembly includes a first hose for low-pressure air and a second hose for high-pressure air, both disposed within the same external hose structure. This merging eliminates the need for multiple separate hoses while maintaining pressure-specific optimization through internal segmentation.
Solution Approach 2:
The patent implements a nested configuration where the second hose (high-pressure) is disposed within the first hose (low-pressure). Both hoses are contained within a common external hose structure, creating a nested arrangement that allows multiple pressure zones to coexist in a single hose assembly. This nesting approach reduces the overall number of hoses needed while preserving pressure-specific functionality.
2Adaptability or versatility
If multiple separate hose assemblies are provided for different air pressure needs, then each task can use the appropriate hose, but the cost and storage requirements increase
Solution Approach 1:
The patent creates a universal hose assembly that can perform multiple functions by providing both high-pressure and low-pressure air through a single device. The hose assembly includes separate internal pathways (first hose and second hose) that allow it to adapt to different pressure requirements for various tasks such as inflating tires, mattresses, or providing vacuum functions, eliminating the need for multiple specialized hoses.
