Cleaning sheet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning sheets with belt-like brushes fail to effectively trap dirt and dust between brush parts, leading to incomplete cleaning due to gaps between the brushes.
Innovation Solution
A cleaning sheet design featuring multiple brush part lines intersecting with each other, with planar seal parts of varying sizes and shapes to form brush parts around these seals, ensuring effective dirt and dust trapping by alternating brush positions and varying fiber lengths for enhanced scraping and trapping capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If belt-like brushes are formed by cutting fibers continuously or intermittently along linear fusion-bonding parts, then the brushes can be formed on the cleaning sheet, but dirt and dust cannot be trapped sufficiently due to gaps between the belt-like brush parts
Solution Approach 1:
The cleaning sheet is divided into multiple brush part lines, each consisting of multiple brush parts disposed intermittently along one direction. These brush part lines are arranged in intersecting directions to create a grid-like pattern that covers the entire surface, ensuring no gaps remain for dirt and dust to escape through.
Solution Approach 2:
The invention transitions from single-direction linear brushes to multi-directional intersecting brush part lines. By arranging brush parts in multiple directions that intersect each other, the cleaning sheet creates a two-dimensional coverage pattern that effectively traps dirt and dust from all directions, solving the gap problem of conventional single-direction brushes.
2Reliability
If planar seal parts of different sizes are used to join sheet substrate and sheet-like fibers, then brush parts with varying fiber lengths are formed for enhanced cleaning, but the manufacturing process becomes more complex
Solution Approach 1:
Planar seal parts of different sizes are strategically positioned at different locations on the cleaning sheet. Larger seal parts create brush parts with longer fibers for trapping dirt and dust, while smaller seal parts create brush parts with shorter fibers for scraping out debris. This local variation in seal part size optimizes cleaning effectiveness across different areas of the sheet.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design ensures effective trapping and scraping of dirt and dust, with short fibers scraping out debris and long fibers trapping it, providing comprehensive cleaning without missing fine particles.
Implementation Method 1
first seal part groups in which each group is constituted by multiple planar seal parts disposed intermittently along the fiber direction of the sheet-like fibers, and second seal part groups in which each group is constituted by planar seal parts disposed intermittently on the positions intersecting with the planar seal parts of the first seal part groups, are disposed in an alternate manner in a direction intersecting with the fiber direction of the sheet-like fibers to join the sheet substrate and the sheet-like fibers

AI summary
Conventional cleaning sheets having brush parts provided on a surface of substratum sheet have been satisfactory in the trapping of dirt or dust at the brush parts but unsatisfactory in the trapping of dirt or dust at areas between brush parts where no brush is present. It is intended to provide a cleaning sheet with which any dirt or dust having sneaked through areas between brush parts and remaining untrapped can be trapped by brush parts provided in alternately positioning relationship adjacent to the brush parts, thereby attaining effective cleaning. The cleaning sheet is cleaning sheet (1) characterized in that it has sheet substratum (2) and, disposed on at least one major surface thereof, multiple brush part lines (3a) each provided with multiple brush parts (3) arranged intermittently along one direction of the sheet substratum (2), the multiple brush part lines arranged in a direction intersecting with the one direction, and that mutually adjacent brush part lines (3a) are provided so that the respective brush parts (3) are alternately positioned.
