Non-Planar Cleaning Article Structure for Better Dust Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning articles, such as reusable dust gathering devices with laterally extending strips, face issues with dust retention and material efficiency, leading to ineffective cleaning and excessive material usage, while disposable options often lack two-sided cleaning capability and efficient dust collection.
Innovation Solution
A cleaning article with tow fibers extending laterally from a spine, featuring a non-planar structure without strips, utilizing tabs or arches that deform out of the plane to increase surface area and debris capture, allowing for two-sided cleaning with reduced material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If laterally extending strips are used to increase surface area, then debris capture is improved, but material usage becomes excessive
Solution Approach 1:
The patent transitions from two-dimensional planar strips to three-dimensional non-planar structures (tabs, arches, protrusions) that extend out of the plane of the support. This dimensional change increases the effective surface area and debris capture volume without proportionally increasing material usage, as the structures utilize the third dimension (height/depth) rather than only extending laterally in the plane.
Solution Approach 2:
The patent employs curved and three-dimensional structures such as arches, domes, and protrusions instead of flat planar strips. These curved surfaces provide greater surface area within constrained material volumes and create more effective debris capture zones through their three-dimensional geometry, resolving the contradiction between surface area and material usage.
2Area of stationary object
If strips extend from both sides of the cloth, then cleaning coverage is improved, but the strips interfere with tow fibers contacting the surface
Solution Approach 1:
The patent segments the support structure into distinct regions: a planar support body and separate non-planar elements (tabs, arches, protrusions) that are integrated at specific locations. This segmentation allows the main support plane to remain relatively flat for fiber contact, while localized three-dimensional elements provide extended cleaning coverage without interfering with the overall fiber-to-surface contact.
Solution Approach 2:
The patent applies non-planar structures locally at specific positions on the support rather than using extensive lateral strips across the entire surface. This localized approach provides enhanced debris capture and cleaning coverage at critical areas while maintaining the overall planarity needed for effective fiber contact with the cleaning surface.
3Ease of manufacture
If reusable dust gathering devices are used, then cost is reduced, but dust retention capability deteriorates
Solution Approach 1:
The patent describes cleaning articles that are designed to be disposable or have limited reusability. By using inexpensive materials and simple construction methods, the article can be discarded after a single use or a few uses, eliminating the need for complex cleaning and maintenance mechanisms while ensuring consistent dust retention performance throughout its service life without degradation from repeated cleaning cycles.

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.
