Stitch-Bonded Cleaning Pad for Fluid Retention and Secure Mop Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning pads for floors and surfaces often lack effective absorption and retention of cleaning fluids, and their attachment systems can be inefficient, leading to suboptimal cleaning performance and user experience.
Innovation Solution
A stitch-bonded cleaning pad with multiple layers of absorbent nonwoven material and a fluid-blocking polymer film, featuring multi-filament stitching yarns that form raised loops for cleaning and flat locking stitches for attachment, creating a hook and loop system for secure attachment to a mop head, allowing for efficient absorption and retention of cleaning fluids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional cleaning pads use simple layering without stitch bonding, then manufacturing is simpler, but absorption and retention of cleaning fluids is insufficient
Solution Approach 1:
The cleaning pad combines multiple materials with different functions: absorbent nonwoven layers for fluid absorption, fluid-blocking polymer film for retention, and multi-filament stitching yarns for structural integrity. This composite structure resolves the contradiction by integrating materials that collectively provide both high absorption/retention capability and manufacturability through stitch bonding technology.
Solution Approach 2:
The absorbent nonwoven layers utilize porous structures to enable efficient fluid absorption and retention. The porous material allows cleaning fluids to be drawn in and held within the pad structure, directly addressing the insufficient absorption and retention problem while maintaining a manufacturable form through stitch bonding.
2Reliability
If cleaning pads use simple attachment methods, then device complexity is reduced, but attachment security to mop head is insufficient
Solution Approach 1:
The multi-filament stitching yarns serve as an intermediary element between the cleaning pad layers and the mop head attachment system. These yarns extend through the pad layers and protrude on the rear surface, providing secure engagement with the mop head while integrating seamlessly into the pad structure through stitch bonding, thus achieving reliable attachment without excessive complexity.
3Productivity
If cleaning pads use uniform surface structure, then manufacturing is easier, but cleaning efficacy is reduced
Solution Approach 1:
The cleaning pad incorporates multi-filament stitching yarns that create localized variations in surface structure, forming raised loops on the cleaning surface. This local quality variation enhances cleaning efficacy by providing different surface textures for better dirt removal, while the overall stitch bonding process remains manufacturable through established techniques.

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 pad provides enhanced absorption and retention of cleaning fluids, with the combination of soft and abrasive yarns improving cleaning efficacy and secure attachment, ensuring effective dirt removal and fluid containment during use.
Implementation Method 1
Interior layers of fibrous material in combination with superabsorbent polymer additives serve to absorb and hold fluid from the surface being cleaned
Implementation Method 2
The pad structure of stitch bonded construction incorporates one or more substrate layers of an absorbent nonwoven material
Implementation Method 3
an optional additional fluid blocking substrate layer of polymer film or other suitable material in juxtaposed relation to the absorbent nonwoven layers
Implementation Method 4
Stitching yarns of multi-filament construction are introduced in stitching relation through the substrate layers
Implementation Method 5
The stitches of yarns across the attachment surface define an engagement surface for attachment to cooperating hooking elements across a surface of a mop head to define a hook and loop attachment system

AI summary
A cleaning pad structure of stitch bonded construction incorporating one or more substrate layers of an absorbent nonwoven material with an optional additional fluid blocking substrate layer of polymer film or other suitable material in juxtaposed relation to the absorbent nonwoven layers. Stitching yarns are introduced in stitching relation through the substrate layers. One face of the pad defines a cleaning surface of raised yarn loops formed by the stitched yarns. The pad further includes an attachment surface facing away from the cleaning surface. The stitches of yarns across the attachment surface define an engagement surface for attachment to cooperating hooking elements across a surface of a mop head to define a hook and loop attachment system.
