Wringing device with a deformable housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wringing devices for cleaning systems, such as mops, are inefficient in evacuating liquid as they only effectively wring the part in contact with the grid, leaving most of the system pressed against itself, resulting in inadequate liquid removal.
Innovation Solution
A wringing device comprising intersecting grids that form a deformable housing, allowing for improved contact and liquid evacuation, with features like a flared passage and a brush guide groove, and a mechanism to hold the device above a bucket for enhanced stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-piece wringing grid is used, then the device structure is simple, but the wringing efficiency is insufficient
Solution Approach 1:
The wringing device is divided into two separate grids (first grid and second grid) that can move relative to each other, allowing independent optimization of each grid's function and improving overall wringing efficiency while maintaining structural simplicity
Solution Approach 2:
The second grid is made movable relative to the first grid, enabling dynamic adjustment of the wringing chamber volume and deformation of the housing to enhance liquid evacuation efficiency during the wringing process
2Device complexity
If the cleaning system is pressed against itself, then the device structure is simple, but liquid evacuation is inadequate
Solution Approach 1:
The liquid evacuation path is extended by creating a wringing chamber between two grids with a flared passage opening, allowing liquid to be directed along a longer path toward the bucket, improving evacuation efficiency without complicating the device structure
Solution Approach 2:
The wringing chamber acts as an intermediary space between the cleaning system and the bucket, facilitating efficient liquid transfer by providing a dedicated evacuation pathway that prevents liquid from being merely redistributed within the cleaning system
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 device achieves more efficient wringing by increasing the contact surface and facilitating liquid drainage, improving the overall wiping efficiency compared to prior art devices.
Implementation Method 1
The wiping of the cleaning system is then carried out by pressing the cleaning system against the wiping grid
Implementation Method 2
The liquid initially contained in the cleaning system is then received directly into the bucket
