Solution Overview

Problem

Existing cleaning articles, such as rags and disposable dusters, are inadequate for cleaning large or heavily wetted surfaces like floors, as they can redeposit dirt and fail to effectively clean crevices or grout lines due to their flat design and material limitations.

Innovation Solution

A laminate construction cleaning article with an absorbent core and hydrophilic gather strip elements, where the gather strip width is greater than the core width, providing a dynamic surface area that changes during use, allowing for effective absorption and retention of liquids while maintaining mobility and preventing re-deposition of dirt.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a generally flat floor sheet is used for cleaning, then liquid absorption capacity is improved, but dirt re-deposition occurs and cleaning effectiveness in crevices is reduced

Engineering Contradiction:
Improveliquid absorption capacityVSAvoidcleaning effectiveness
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The floor cleaning article transitions from a static flat sheet to a dynamic structure with movable strips that can independently move and present different surface areas to the floor during cleaning, preventing dirt re-deposition and enhancing crevice cleaning

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cleaning article is divided into multiple functional segments including a sheet portion, gather strip element with strips, and absorbent core, where each segment performs a specific function and can move independently to adapt to different cleaning needs

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If tow fibers are used for wet cleaning, then cleaning capability is improved, but fibers become matted and are unsuitable for large or heavily wetted surfaces

Engineering Contradiction:
Improvecleaning capabilityVSAvoidfiber structure stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The invention changes the material parameter from traditional tow fibers to a non-matting gather strip material that maintains its structural integrity and cleaning effectiveness even when heavily wetted or used on large surfaces

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The cleaning article uses a composite structure combining a sheet portion, absorbent core, and gather strip element with strips, where the gather strip material is specifically selected to resist matting while providing effective cleaning capability

Inventive Principle:
Principle #40Composite materials

3Area of moving object

If the gather strip width is greater than the core width, then dynamic surface area is increased for better cleaning, but structural complexity increases

Engineering Contradiction:
Improvedynamic surface areaVSAvoidstructural complexity
Core Design Contradiction:
Area of moving objectVSDevice complexity

Solution Approach 1:

The gather strip element extends beyond the core boundaries in the lateral dimension, creating a wider effective cleaning surface area while maintaining a simple layered construction that does not significantly increase structural complexity

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A cleaning article. The cleaning article has a laminate construction. The cleaning article has a width and comprises a sheet, having an inwardly oriented face and an outwardly oriented face opposed thereto. An absorbent core is joined to one face of the sheet. A hydrophilic gather strip element having strips is joined to the sheet. The core has a core width and the gather strip element has a gather strip width which is greater than the core width. The differential widths provide a construction which allows the strips to advantageously present a dynamically changing area to the target surface during cleaning, under normal usage conditions. By changing the surface area, more liquids, and associated debris, can be cleaned from the target surface.
