Sanitary Fitting with Nested Hoses for Jam-Free Spout Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sanitary fittings with multiple hoses for delivering mixed and treated water to a spout are prone to jamming and installation issues when the spout is pulled out or installed, as separate hoses can impede each other.
Innovation Solution
A sanitary fitting design where a first hose is located partially within a second hose, allowing both fluids to be carried separately to the spout without the need for multiple hoses, with the first hose running concentrically through the second hose and the second fluid being delivered through an annular space between them, reducing the complexity and interference during spout movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate hoses are used for delivering mixed water and treated water to the spout, then both fluids can be delivered separately, but the hoses can jam or impede each other when the spout is pulled out or during installation
Solution Approach 1:
The first hose is inserted through the second hose, creating a nested configuration where one hose passes through the other. This nesting arrangement allows both hoses to be routed together through the spout without interfering with each other during spout installation or removal, while still maintaining separate fluid delivery paths for mixed water and treated water
2Adaptability or versatility
If multiple separate hoses are used for multiple fluids, then each fluid can be delivered independently, but the device complexity and installation difficulty increase
Solution Approach 1:
Multiple hoses carrying different fluids are merged into a single bundled arrangement where hoses are routed together through the spout. This combining approach maintains the ability to deliver multiple fluids independently while reducing the overall complexity of the hose management system and simplifying installation procedures

AI summary
A sanitary fitting having a housing with a spout, wherein a first fluid can be carried through a first hose to an outlet of the spout and a second fluid can be carried through a second hose to the outlet of the spout, and wherein the first hose is located in the second hose.
