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

VSEngineering 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

Engineering Contradiction:
Improvedust gathering capabilityVSAvoidmaterial usage
Core Design Contradiction:
Quantity of substanceVSLoss of substance

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.

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

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

Engineering Contradiction:
Improvecleaning coverageVSAvoidfiber contact capability
Core Design Contradiction:
Area of stationary objectVSEase of operation

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.

Inventive Principle:
Principle #3Local quality

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

Engineering Contradiction:
ImprovecompactnessVSAvoidsurface area
Core Design Contradiction:
Volume of moving objectVSQuantity of substance

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.

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

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.
