Rotating Hose Coupling Sleeve to Prevent Twist and Kink
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional hose coupling devices often result in kinks and twists when used for spraying water, making it difficult to direct the spray and can lead to the nozzle becoming detached, causing inefficiency and inconvenience.
Innovation Solution
A hose coupling device with a sleeve component featuring a female hose thread on one end and a male hose thread on the other, incorporating an O-ring water seal sandwiched between bearing surfaces, allowing the sleeve to rotate independently from the nozzle and reducing torque, thus preventing kinks and leaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional hose coupling device is used, then the hose can be connected to the nozzle, but the hose develops twists and kinks when moving around, making it difficult to spray water in a specific direction
Solution Approach 1:
The coupling device incorporates a rotating metal sleeve that can rotate independently from the spray nozzle, allowing the hose to move freely without developing twists and kinks. This dynamic element enables the hose to adapt its position while maintaining connection, resolving the contradiction between ease of directional control and hose configuration stability.
2Reliability
If the hose coupling is made secure to prevent detachment, then the nozzle remains firmly attached, but the hose cannot rotate freely causing torque buildup and kinks
Solution Approach 1:
The rotating metal sleeve provides a dynamic connection that maintains firm attachment between hose and nozzle while allowing rotational movement. This resolves the contradiction by enabling both reliable connection and free hose movement, preventing torque buildup and kinks.
Solution Approach 2:
The rotating metal sleeve acts as an intermediary element between the hose and nozzle, providing a mechanism that allows relative rotation while maintaining secure connection. This mediator enables the hose to move freely without compromising attachment reliability.
3Ease of operation
If the coupling device allows free rotation to eliminate kinks, then the hose can move freely, but the nozzle may become unthreaded and detach
Solution Approach 1:
The rotating metal sleeve with bearing surfaces enables free rotation to eliminate kinks while the integrated O-ring seal and threaded connection maintain secure attachment. This dynamic design resolves the contradiction by allowing movement freedom without compromising nozzle attachment reliability.
4Ease of operation
If a rotating mechanism is added to eliminate kinks, then the hose can move freely, but the device complexity increases
Solution Approach 1:
The rotating metal sleeve with bearing surfaces adds minimal structural complexity while enabling free hose movement and eliminating kinks. The simple rotational mechanism provides significant operational improvement without substantially increasing device complexity.

AI summary
A hose coupling device is disclosed. The device is an improved hose coupling that allows the hose to move more freely than a traditional coupling. The hose coupling device comprises a sleeve component with a female hose thread on one end and a male hose thread on the other end. The sleeve component further comprises a bearing above and below an O-ring water seal. The hose coupling component rotates independently from the hand nozzle component and eliminates the twist/kink of the hose when walking around spraying water.
