Rotatable Water Transfer Joint Structure to Prevent Faucet Tube Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water purifier systems face challenges during installation and use due to the tendency of double-layer tube bodies to rotate and fall off from the water transferring head, caused by threaded connections.
Innovation Solution
A water transferring device with a connection structure that allows for rotational movement of the water inlet and outlet joints around their own axes, featuring grooves and clamping plates to inhibit movement and prevent falling, enabling secure attachment to the body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If threaded connections are used to fix the double-layer tube body to the water transferring head, then the connection is simple to manufacture, but the double-layer tube body may rotate and fall off during use
Solution Approach 1:
The connection structure allows the water inlet joint and water outlet joint to rotate relative to the body by specific angles (first angle and second angle respectively), transforming the rigid fixed connection into a dynamic adjustable connection. This enables the joints to adapt to installation angle variations while preventing excessive rotation that would cause detachment, thus resolving the contradiction between ease of manufacture and connection reliability
Solution Approach 2:
The patent introduces angular parameters (first rotation angle and second rotation angle) to control the rotational movement of joints. By limiting the rotation angles to specific ranges, the connection structure achieves both ease of installation (through allowed rotation) and prevention of detachment (by restricting rotation to safe angles), effectively resolving the technical contradiction
2Ease of operation
If the double-layer tube body is fixedly connected through threaded connections, then the installation process is simple, but the tube body may move and fall off during subsequent use
Solution Approach 1:
The connection structure enables controlled rotational movement of joints during installation and use, allowing operators to adjust the angles of water inlet and outlet joints within safe ranges. This dynamic capability simplifies installation by accommodating angle variations while preventing detachment through angle limits, resolving the contradiction between ease of operation and connection stability
Solution Approach 2:
The connection structure preemptively prevents detachment by limiting the rotation angles of joints to predetermined safe ranges. By establishing these angular constraints before any potential detachment issue occurs, the design ensures that while joints can move for installation flexibility, they cannot rotate enough to fall off, thus resolving the contradiction between ease of installation and connection reliability

AI summary
A water transferring device is provided and comprises a body having a water passage chamber, a first water inlet joint having a first water inlet passage and connected to the body, and a water outlet joint having an outer water passage and an inner water passage. The first water inlet joint and the water outlet joint enable the inner water passage to be in communication with the first water inlet passage. The water passage chamber is in communication with the outer water passage. At least one of the first water inlet joint or the water outlet joint comprises a connection structure connected to the body and enabling the at least one of the first water inlet joint or the water outlet joint to be at least rotated for a specific angle around an axis of the at least one of the first water inlet joint or the water outlet joint.
