Swingable Water-Blocking Element for Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water outlets with elastic water-blocking elements face issues such as loss of elasticity over time, leading to leakage, and inability to seal when the control bar deviates from the central axis.
Innovation Solution
A water outlet structure featuring a swingable water-blocking element mounted on a control bar with an annular groove and E-shaped buckles, allowing the element to swing and engage the shrinking section of the sleeve to prevent leakage, even when the control bar is off-center, utilizing an O-ring for enhanced sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the water blocking element is made of elastic material and fixed on the control bar, then it can seal the flowing channel when the control bar is centered, but it cannot seal the shrinking section when the control bar deviates from the central axis
Solution Approach 1:
The water blocking element is designed to be movable relative to the control bar rather than fixed. It can swing radially outward when the control bar deviates from the central axis, allowing the element to maintain contact with the shrinking section and preserve sealing effectiveness under misaligned conditions.
2Reliability
If the water blocking element is made of elastic material, then it can deform to seal the flowing channel, but it hardens and loses elasticity over time, requiring frequent replacement
Solution Approach 1:
The invention changes the material parameter from elastic material to hard material (such as plastic or metal). This hard material does not harden over time like elastic material does, thereby maintaining its sealing capability throughout the service life without requiring frequent replacement.
3Device complexity
If the water blocking element is fixed on the control bar, then it is simple in structure, but it cannot swing to accommodate control bar deviation, resulting in leakage
Solution Approach 1:
The mounting structure allows the water blocking element to swing radially relative to the control bar through a simple pivot connection. This dynamic capability enables the element to compensate for control bar deviation and maintain sealing performance without adding significant structural complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures effective sealing and prevents water leakage by allowing the water-blocking element to swing and engage the shrinking section, maintaining functionality even when the control bar is not centrally aligned, thus reducing the need for frequent replacements.
Implementation Method 1
The water blocking element 61 is made of an elastic material such as rubber. When the user pulls the control bar 6 along the axial direction, the water blocking element 61 engages a shrinking section 51 of the flowing channel 5. The water blocking element 61 thus deforms to seal the flowing channel 5, preventing leakage.

AI summary
A water outlet has a sleeve to form a flowing channel and a control bar extends in the axial direction of the sleeve. The control bar has a water-blocking element that has a through hole and is mounted on the control bar. Both sides of the water-blocking element on the control bar are formed with a blocking part. The diameter of the through hole is larger than the diameter of the control bar. The distance between the two blocking parts is slightly larger than the thickness of the water-blocking element, so that the water-blocking elements can slightly swing with respect to the control bar to block the flowing channel.
