Embossed Cleaning Sheet Structure for Dust Capture and Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning sheets with low-density areas for improved dust collection properties often compromise on strength, leading to twisting and tearing during use, which degrades their collection efficiency.
Innovation Solution
A cleaning sheet design featuring embossed sections compressed in the thickness direction and non-embossed sections arranged alternately along bent sections, providing excellent dust collection properties while maintaining sheet strength by alternating raised and sunken embosses and strategically placing non-embossed sections at predetermined intervals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If low-density areas are formed in the sheet fiber to improve dust collection properties, then collection properties are improved, but sheet strength is reduced causing twisting and tearing
Solution Approach 1:
The sheet is segmented into multiple embossed sections and non-embossed sections arranged in a specific pattern. The embossed sections provide dust collection functionality while the non-embossed sections maintain sheet strength, resolving the contradiction between collection properties and strength.
Solution Approach 2:
Different sections of the sheet have different local qualities: embossed sections with compressed fibers for dust collection and non-embossed sections with intact fiber structure for strength. This local differentiation allows the sheet to simultaneously achieve good collection properties and maintain sufficient strength.
2Productivity
If embossed sections are compressed in the thickness direction to increase volume, then dust collection properties are improved, but sheet uniformity is reduced affecting overall performance
Solution Approach 1:
The sheet is divided into multiple embossed sections and non-embossed sections arranged in an alternating pattern. This segmentation maintains overall sheet uniformity while allowing local embossing for dust collection, resolving the contradiction between collection properties and sheet uniformity.
Solution Approach 2:
The sheet has different local qualities in embossed and non-embossed sections, with the non-embossed sections providing structural uniformity and the embossed sections providing dust collection functionality. This local differentiation resolves the contradiction between collection properties and overall uniformity.

AI summary
A cleaning sheet (100) that: is replaceably attached to a flat head section of a cleaning tool; forms a cleaning surface covering the bottom surface of the head section; is bent along a longitudinal edge of the head section and locked to the upper surface of the head section; and has an embossed section (20) having a sheet compressed in the thickness direction and an uncompressed non-embossed section (30) that are arranged alternately along a bent section (S) bent along the longitudinal edge. As a result, a cleaning sheet can be provided that maintains sheet strength and has excellent collection properties.
