Flat Mop Wringing Mechanism With Unidirectional Handle Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional self-wringing flat mops often experience degraded wringing performance due to inappropriate handle operation, leading to inefficient water removal and user discomfort.
Innovation Solution
A self-wringing flat mop design featuring a transmission assembly with a unidirectional limiting ring and limiting rib, along with a control lever, which prevents inappropriate handle spinning and allows for easy restoration of the mop to its original state, ensuring effective water removal without direct contact with the cleaning part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the mop handle is turned to actuate the plate to collapse and wring water out of the cleaning part, then wringing efficiency is improved, but the mop may spin wholly if turned with inappropriate action, degrading wringing effect
Solution Approach 1:
The patent applies preliminary anti-action by introducing a unidirectional limiting ring with ratchet teeth that prevent the mop handle from rotating in the wrong direction before inappropriate action occurs. The limiting rib on the connection rod engages with the ratchet teeth to confine the mop handle to turn only in the correct single direction, thereby preventing the harmful spinning effect before it can degrade wringing performance
Solution Approach 2:
The patent implements feedback through the unidirectional limiting ring mechanism that provides immediate mechanical feedback when the mop handle is attempted to be rotated in the wrong direction. The ratchet teeth engage with the limiting rib to provide tactile and mechanical feedback, guiding the user to operate the handle in the correct direction for effective wringing
2Ease of operation
If the transmission assembly allows free rotation for easy operation, then ease of operation is improved, but the mop handle may spin in multiple directions causing degraded wringing performance
Solution Approach 1:
The patent applies asymmetry through the unidirectional limiting ring with ratchet teeth that are asymmetrically designed to allow rotation in only one direction. The ratchet teeth are configured to engage with the limiting rib in a single direction, creating an asymmetric constraint that permits easy operation in the correct direction while preventing rotation in the wrong direction that would degrade wringing performance
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
The design enhances wringing efficiency by preventing reverse spinning of the mop handle, maintaining effective water removal and providing a more hygienic, convenient operation for users.
Implementation Method 1
Two sides of the central plate are respectively hinged with the two side plates via torsion springs
Implementation Method 2
The unidirectional limiting ring comprises a plurality of ratchet teeth arranged annularly... The ratchet teeth confine the limiting rib to slide unidirectionally and confine the mop handle to turn in a single direction
Implementation Method 3
The control lever comprises a protruding trigger protruding from the holding sleeve and contacting the guiding member, and a levering element connected with the protruding trigger. The levering element is driven during operation to turn pivotally with respect to the holding sleeve and make the protruding trigger slide on the guiding member

AI summary
A self-wringing flat mop includes a flat mop head, a mop handle and a holding sleeve. The mop handle includes a connection rod, a holding rod, and a transmission assembly. The holding rod is operated to rotate. The transmission assembly transmits rotation to the connection rod. The connection rod drives the flat mop head to collapse and wring out water. The transmission assembly includes a first engaging member and a second engaging member for undertaking engagement-disengagement actions. The holding rod includes a limiting rib. The holding sleeve sleeves the mop handle and includes a control lever. The control lever is turned pivotally with respect to the holding sleeve to separate the first engaging member from the second engaging member and restore the collapsed flat mop head to the flattened state. The holding sleeve includes a unidirectional limiting ring corresponding to the limiting rib.
