Non-Planar Cleaning Article for Two-Sided Dust Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning articles, such as reusable dust gathering devices with feathers or synthetic fibers, face issues with dust retention and require additional cleaning steps, while disposable options often use excessive material and only clean one side of a surface.
Innovation Solution
A cleaning article with tow fibers extending laterally from a spine, featuring a non-planar structure without lateral strips, utilizing tabs or arches that deform out of the plane to increase surface area and dust capture, allowing for two-sided cleaning with reduced material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If laterally extending strips are added to increase surface area, then dust gathering capability is improved, but material usage increases excessively
Solution Approach 1:
The patent transitions from two-dimensional planar strips to three-dimensional non-planar structures (tabs, arches, or protrusions) that extend out of the plane of the disposable article. This dimensional change allows the tow fibers to deform and contact the target surface more effectively without requiring excessive lateral strip material, thus improving dust gathering capability while controlling material usage.
2Area of stationary object
If strips extend from both sides of the article, then cleaning coverage is improved, but the strips interfere with tow fibers contacting the surface
Solution Approach 1:
The patent applies different structural qualities to different regions of the article. The non-planar structures (tabs, arches, or protrusions) are strategically positioned and dimensioned to provide local deformation zones where tow fibers can effectively contact the surface, while maintaining appropriate spacing and geometry to prevent interference from excessive strip material.
3Volume of moving object
If a compact design is used to access small spaces, then reach is improved, but surface area for dust gathering is reduced
Solution Approach 1:
The patent creates a compact disposable article in the planar view but introduces three-dimensional non-planar structures (tabs, arches, or protrusions) that extend out of the plane. This allows the article to maintain a compact form factor for accessing small spaces while the deformable non-planar structures provide increased effective surface area and tow fiber contact capability for dust gathering.

AI summary
A plural sided cleaning article optionally removably attachable to a handle. The cleaning article may have a layered construction. The construction may comprise a sheet, to accommodate optional and removable attachment to a handle, intermediate tow fibers, and a non-planar structure extending outwardly from the side of the tow fibers opposite the sheet. This arrangement avoids the disadvantage of strips according to the prior art while increasing the surface area of the tow fibers.
