Self-Wringing Flat Mop Head With Four-Point Pressure Wringing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flat mop designs lack an efficient mechanism for wringing out mop heads, particularly for self-wringing configurations, which often require manual effort and may not effectively apply pressure or friction across the entire mop surface, leading to incomplete moisture removal.
Innovation Solution
A self-wringing flat mop design featuring a perimeter structure with rollers or blades that applies pressure and friction to the mop head, utilizing a four-point contact mechanism with guide surfaces and adjustable rollers to ensure effective wringing action, allowing for linear movement and increased pressure distribution along the mop head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a self-wringing mechanism is added to a flat mop, then wringing effectiveness is improved, but device complexity increases
Solution Approach 1:
The wringing mechanism is designed to be self-actuating through the user's natural pushing motion. The linear wringing assembly moves automatically as the user pushes the mop forward, converting forward motion into wringing action without requiring separate manual operation. The pivotable wings and cam surfaces work together to automatically apply pressure and friction to the mop head material during normal mop movement.
Solution Approach 2:
The mop head is divided into two pivotable wings or half-plates that can move independently relative to each other. This segmentation allows each wing to be actuated by its own cam surface and pressure application point, enabling distributed pressure application across the mop head material while maintaining overall system simplicity.
2Productivity
If pressure is applied to wring the mop head, then moisture removal is improved, but ease of operation deteriorates
Solution Approach 1:
The wringing mechanism uses dynamic cam surfaces that automatically adjust pressure application based on the mop head's position and moisture content. As the user pushes the mop forward, the cam surfaces progressively engage and disengage, creating a rhythmic pressing and releasing action that maintains effective wringing without requiring the user to apply additional force or adjust settings.
Solution Approach 2:
The cam surfaces are designed with curved profiles that naturally concentrate force at specific contact points during the wringing cycle. The curved geometry transforms the user's linear pushing motion into rotational or pivoting motion of the wings, automatically generating high localized pressure for effective moisture removal while requiring minimal user effort.
3Productivity
If a perimeter structure with rollers is used, then wringing action is improved, but device complexity increases
Solution Approach 1:
The perimeter structure with rollers serves multiple functions simultaneously: it applies friction to the mop head material for wringing, supports the mop head during the wringing cycle, and guides the linear movement of the wringing assembly. The rollers are integrated into the existing wing structure rather than being separate components, reducing overall device complexity while maintaining multi-functionality.
4Stress or pressure
If four-point contact mechanism is implemented, then pressure distribution is improved, but manufacturing precision requirements increase
Solution Approach 1:
The four-point contact mechanism uses cam surfaces with specific geometric profiles that automatically adjust contact pressure distribution. The cam geometry is designed to compensate for variations in mop head loading and position, maintaining relatively uniform pressure distribution across the four contact points through geometric design rather than requiring precision adjustment mechanisms.
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 the ease of use and effectiveness of wringing by distributing pressure evenly across the mop head, allowing for efficient moisture removal and reducing manual effort, while maintaining adaptability to different mop sizes and surface profiles.
Implementation Method 1
the self-wringing mop assembly has a perimeter structure that extends around four sides of a mop head when in a wringing configuration... the structure can include four rollers or four pressure surfaces for applying a wringing action to a mop head
Implementation Method 2
the perimeter structure can be used to apply pressure or friction for wringing liquid from mop head material

AI summary
Flat mops and self-wringing flat mops can include a wringing configuration for applying a linear wringing motion to a mop head assembly, such as may occur along an axis coaxial with a handle. Four-point self wringing configurations may include four-point guide surfaces and/or four-point pressure points for wringing a mop head assembly.
