Solution Overview

Problem

Existing cleaning pads for floors and surfaces often lack effective absorption and retention of cleaning fluids, and their attachment mechanisms can be inefficient, leading to suboptimal cleaning performance and user experience.

Innovation Solution

A stitch-bonded cleaning pad structure with multiple layers of absorbent nonwoven material and a fluid-blocking polymer film, featuring multi-filament stitching yarns that form raised loops for a cleaning surface and flat locking stitches for attachment to a mop head, providing both efficient fluid absorption and secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If disposable cleaning pads with layered construction are used, then fluid absorption and retention are improved, but attachment mechanism efficiency deteriorates

Engineering Contradiction:

Improvefluid absorption and retentionVSAvoidattachment mechanism efficiency

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The patent combines the attachment mechanism directly with the cleaning pad structure by integrating a looped stitching yarn system that serves dual purposes: bonding the layered pad construction together and providing the attachment interface for the mop head, eliminating the need for separate attachment components and improving both fluid retention and attachment reliability

Inventive Principle:

Principle #5Merging (Combining)

2Manufacturing precision

If stitch bonding techniques are used to form uniform surfaces, then surface uniformity is improved, but cleaning performance deteriorates

Engineering Contradiction:

Improvesurface uniformityVSAvoidcleaning performance

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The patent applies local quality by using looped stitching yarns that create raised, textured surfaces at specific locations where cleaning action is needed, while maintaining flat stitched areas for fluid distribution, thus achieving both surface uniformity in terms of coverage and enhanced cleaning performance through localized texture variations

Inventive Principle:

Principle #3Local quality

3Productivity

If multi-filament stitching yarns with loops are used, then cleaning performance is improved, but attachment security deteriorates

Engineering Contradiction:

Improvecleaning performanceVSAvoidattachment security

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The looped stitching yarns serve multiple functions simultaneously: they create raised loops for particle trapping and scrubbing action on the cleaning surface, while the same looped structure on the reverse side provides effective engagement surfaces for hook-and-loop attachment to the mop head, thus achieving both enhanced cleaning performance and secure attachment

Inventive Principle:

Principle #6Universality (Multi-functionality)

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.
