Curved Mop Head Structure for Stubborn Stain Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional string mops are ineffective in removing scuff marks and stubborn stains due to insufficient friction, despite attempts to incorporate abrasive materials.
Innovation Solution
A mop head design featuring a dome-shaped body with a curved formation and integrated cleaning pads or elements, allowing for increased pressure and friction application, along with a pivoting mechanism to enhance cleaning capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional string mops use microfibre or cloth strips, then the mop can clean general surfaces, but it cannot provide sufficient friction to remove stubborn stains
Solution Approach 1:
The mop head incorporates a formation with a curved surface that concentrates cleaning force at specific contact points with the surface. This localizes the cleaning action to areas where stains are present, providing intensified friction and pressure exactly where needed rather than distributing force uniformly across all cleaning strings.
Solution Approach 2:
The formation features a curved surface that allows the mop to pivot and conform to surface contours. This curvature enables the cleaning strings to be pressed against the surface at optimal angles, maximizing friction contact area and effectiveness for removing stubborn stains while maintaining adaptability to different surface geometries.
2Object-affected harmful factors
If abrasive material is added to target stubborn stains, then stain removal improves, but the mop structure becomes more complex
Solution Approach 1:
The formation integrates multiple functions into a single structural element: it provides the curved pivoting surface, holds the cleaning strings in proper alignment, and creates the mechanical leverage needed to press strings against the surface. This merged structure eliminates the need for separate abrasive components while achieving enhanced stain removal through improved force application.
Solution Approach 2:
The formation serves multiple purposes simultaneously: it acts as a structural support for the cleaning strings, provides a pivoting mechanism for adapting to surface contours, and creates the pressure distribution needed for effective stain removal. This multi-functionality reduces overall device complexity compared to adding separate abrasive components.
3Object-affected harmful factors
If the mop head applies increased pressure to stubborn stains, then cleaning effectiveness improves, but the mop becomes harder to operate
Solution Approach 1:
The curved surface of the formation enables dynamic adaptation to surface contours and user applying force. As the user pushes the mop against a surface, the formation naturally pivots and conforms to the geometry of the surface and stain location, automatically optimizing the angle and distribution of pressure without requiring the user to manually adjust the mop angle or position.
