Fiber-Bound Cleaning Sheet for Large Dirt Particle Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning sheets are inadequate for effectively removing large dirt particles due to fiber limitations and inefficient contact with cleaning surfaces, as they tend to crinkle during cutting and fail to thoroughly utilize the entire cleaning area.
Innovation Solution
A cleaning sheet design featuring a base sheet with fiber-bound materials of varying lengths and densities arranged in rows or overlapping configurations, allowing for enhanced dirt capture and maintenance, with the option of a substrate sheet for improved contact and cleaning performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If long fiber filament is cut to form brush portions, then cleaning sheet can be manufactured, but fiber crinkles during cutting and length is limited, making it difficult to remove large dirt particles
Solution Approach 1:
The cleaning sheet is divided into multiple regions with different fiber lengths. The first region has longer fibers for capturing large dirt particles, while the second region has shorter fibers for fine dust. This segmentation allows each region to specialize in different particle sizes, resolving the contradiction between manufacturing constraints and large particle removal capability.
Solution Approach 2:
Different regions of the cleaning sheet have different fiber length characteristics tailored to specific cleaning needs. The first region uses longer fibers specifically for large dirt particles, while the second region uses shorter fibers for fine dust. This local differentiation optimizes performance for different particle sizes without being constrained by uniform manufacturing limitations.
2Productivity
If cleaning sheet is moved during cleaning, then entire face can be utilized, but central portion does not contact cleaning surface, reducing wiping function
Solution Approach 1:
The cleaning sheet has different regions with different functions: the first region with longer fibers is optimized for capturing large dirt particles, while the second region with shorter fibers handles fine dust. This local functional differentiation ensures that each region contributes effectively to dirt removal regardless of contact position, maintaining effectiveness even when the sheet is moved during cleaning.
Solution Approach 2:
The invention transitions from a single uniform fiber layer to a multi-layer structure with different fiber lengths arranged in specific regions. This dimensional change creates a three-dimensional cleaning surface that can effectively capture particles of different sizes and positions, improving overall utilization and effectiveness.
3Object-generated harmful factors
If fiber length is increased to capture large dirt particles, then cleaning performance improves, but manufacturing difficulty increases and fiber control becomes harder
Solution Approach 1:
Instead of using uniformly long fibers throughout the entire sheet, the invention segments the cleaning sheet into regions with different fiber lengths. The first region uses longer fibers for large particle capture, while the second region uses shorter fibers that are easier to manufacture and control. This segmentation maintains the benefit of long fibers where needed while reducing manufacturing complexity overall.
Solution Approach 2:
The invention varies the fiber length parameter across different regions of the cleaning sheet. By changing the fiber length parameter from long in the first region to short in the second region, the invention optimizes both cleaning performance for large particles and ease of manufacture, avoiding the need to process uniformly long fibers across the entire sheet.

AI summary
Provided is a cleaning sheet in which a plurality of fiber bound materials produced by bundling a plurality of fibers is joined on a base sheet, and at least two adjacent bound fiber materials have respectively different length in the longitudinal direction of the fibers and different density, to constitute a cleaning portion and which can sufficiently wipe off even relatively large dirt particles.
