Tow Fiber Cleaning Sheet With Movable Strips for Wet Floor Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning articles, such as rags, paper towels, and disposable dusters, are inadequate for effectively cleaning large or heavily wetted surfaces as they can redeposit dirt, damage floors, and fail to reach crevices or grout lines, especially with newer flooring materials that are difficult to wet and prone to streaking or filming.
Innovation Solution
A disposable cleaning article with a laminate construction comprising a sheet and cleaning strip element joined by an elongate bond, featuring tow fibers oriented transversely to the strips, which provides a dynamically changing surface area for cleaning by presenting different portions of the cleaning strip element to the target surface under pressure, allowing for effective absorption and debris removal without redeposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If disposable dusters with tow fibers are used for wet cleaning, then wet cleaning capability is improved, but the tow fibers become matted and are not suitable for cleaning large or heavily wetted surfaces
Solution Approach 1:
The cleaning article is divided into distinct functional zones: a first region with tow fibers for dry dust gathering, a second region with hydrophilic fibers for wet cleaning and liquid absorption, and a third region with hydrophobic fibers for water repellency. This segmentation allows each region to perform its specific function without the tow fibers becoming matted, enabling effective cleaning of large and heavily wetted surfaces.
Solution Approach 2:
Different regions of the cleaning article are assigned different fiber properties tailored to specific cleaning needs. The hydrophilic region absorbs liquids and soils, the hydrophobic region repels water to prevent redeposition, and the tow fiber region provides mechanical abrasion for dry cleaning. This local differentiation resolves the contradiction by ensuring tow fibers remain effective for their intended purpose while other regions handle wet cleaning tasks.
2Quantity of substance
If sheets with large amounts of absorbent cellulose are used for floor cleaning, then liquid absorption is improved, but insoluble soils are not removed and soluble soils are inadequately absorbed resulting in streaking and filming
Solution Approach 1:
The cleaning article segments cleaning functions into distinct regions: tow fibers for mechanical removal of insoluble soils, hydrophilic fibers for absorption of soluble soils and liquids, and hydrophobic fibers for preventing redeposition. This segmentation ensures both thorough soil removal and streak-free finishes by assigning specific tasks to appropriate fiber types.
Solution Approach 2:
The cleaning article uses a composite structure combining three different fiber types (tow fibers, hydrophilic fibers, and hydrophobic fibers) in a single article. This composite approach integrates the advantages of each fiber type: mechanical cleaning capability, liquid absorption, and anti-redeposition properties, thereby achieving both effective soil removal and streak-free results.
3Productivity
If reusable microfiber pads are used for cleaning, then cleaning capability is improved, but the floor is damaged and filming/streaking occurs after repeated washings
Solution Approach 1:
The cleaning article is designed as a disposable product that combines the cleaning effectiveness of reusable microfiber pads with the benefit of being discarded after use. This eliminates the floor damage and filming issues associated with reused microfiber pads, as the article is not washed and reused multiple times. The disposable nature ensures consistent performance without degradation from repeated washing.
Solution Approach 2:
The disposable article uses a composite fiber structure that provides effective cleaning capability similar to reusable microfiber pads, but without the harmful effects of reuse. The combination of tow fibers, hydrophilic fibers, and hydrophobic fibers delivers thorough cleaning while the disposable nature prevents floor damage and filming that occur with repeated washing of reusable pads.
4Area of stationary object
If a generally flat floor sheet is used for cleaning, then coverage area is improved, but dirt is redeposited if the sheet is saturated and crevices or grout lines are not adequately cleaned
Solution Approach 1:
The cleaning article incorporates a three-dimensional structure with raised cleaning surfaces and recessed regions that allow the article to dynamically adapt to floor surfaces. The hydrophilic and hydrophobic regions create a textured surface that can reach into crevices and grout lines while maintaining broad coverage. This dynamic structure prevents dirt redeposition by ensuring continuous contact with the floor surface.
Solution Approach 2:
The cleaning article transitions from a two-dimensional flat sheet to a three-dimensional structure with raised regions and recesses. This dimensional change enables the article to access crevices and grout lines while maintaining large coverage area. The elevated cleaning surfaces can penetrate into gaps and crevices, improving cleaning effectiveness without sacrificing coverage.

AI summary
A cleaning article for cleaning a target surface. The cleaning article has strips which present a dynamically changing surface area to the target surface during use. The surface area has also has a bundle of tow fibers which may be oriented transverse to the strips. The tow fibers may extend outwardly from the plane of the strips, allowing particles to migrate towards and be retained near the center of the cleaning article, without interfering with the strips.
