Swivel Hose Connection with Segmented Rotation to Prevent Kinking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swivel joints do not effectively prevent kinking in hoses, particularly in vacuum hoses used with dust generating devices, and existing swivel connections for water hoses are not applicable in this context.
Innovation Solution
A swivel hose connection device comprising a spindle tube, swivel tube, and fixed tube, where the swivel tube is freely rotatable on the spindle tube and has a larger outer diameter than a lip, allowing hose segments to rotate independently and preventing kinking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional swivel joint is used at the end of a hose, then the hose can rotate relative to the vacuum unit, but the hose segments cannot rotate independently to prevent kinking
Solution Approach 1:
The hose is divided into multiple segments with swivel joints positioned at intervals along the hose length. Each swivel joint allows independent rotation of adjacent hose segments, enabling the hose to flex and bend without kinking while maintaining connection to the vacuum unit.
Solution Approach 2:
The swivel joints are designed to be freely rotatable, allowing the hose segments to dynamically adjust their orientation in response to movement and flexing. This dynamic rotation capability prevents kinking by allowing the hose to accommodate bending stresses.
2Adaptability or versatility
If water hose swivel connections are used, then connection flexibility is improved, but they are not applicable to vacuum hoses due to design differences
Solution Approach 1:
The swivel joint design incorporates features that make it universally applicable to vacuum hoses while maintaining the flexibility benefits of water hose connections. The joint structure, lip configuration, and attachment mechanism are designed to work specifically with vacuum hose requirements while achieving similar flexibility.
Solution Approach 2:
The swivel joint incorporates a lip structure with specific dimensional relationships (swivel tube outer diameter greater than lip outer diameter) that provides localized functionality tailored for vacuum hose applications, distinguishing it from generic water hose connections.
3Reliability
If multiple swivel joints are positioned along the hose, then kinking is prevented through independent segment rotation, but device complexity increases
Solution Approach 1:
The hose is divided into multiple segments with swivel joints positioned at intervals along the hose length. Each swivel joint allows independent rotation of adjacent hose segments, enabling the hose to flex and bend without kinking while maintaining connection to the vacuum unit.

AI summary
A swivel hose connection device includes a spindle tube and a lip extending circumferentially outward from the spindle tube such that the spindle tube extends away from the lip. The spindle tube is extended through a swivel tube such that the lip inhibits the spindle tube from passing fully through the swivel tube. The swivel tube is freely rotatable on the spindle tube adjacent the lip. The spindle tube is extended through a fixed tube and is fixed to the spindle tube such that the fixed tube is fixed relative to the spindle tube. The swivel tube has an outer diameter greater than an outer diameter of the lip such that the swivel tube and the fixed tube are attachable to respective hose segments so the hose segments are independently rotatable relative to each other.
