Cleaning Sheet Brush Structure for Uniform Dust Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cleaning tools with zigzag transverse ends result in fibers of varying lengths, leading to poor cleaning effectiveness, particularly in areas with shorter fiber lengths.
Innovation Solution
A cleaning tool with a cleaning sheet and holder, featuring a brush part composed of fibers of uniform length, including a first and second brush region where the second region is longer and protrudes, enhancing cleaning efficacy by ensuring consistent fiber length and orientation across the tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the cleaning sheet has zigzag transverse ends, then the fiber layer has various lengths in the transverse direction, but the cleaning effect deteriorates in parts with short fiber lengths
Solution Approach 1:
The invention extracts the problematic zigzag configuration from the transverse ends of the cleaning sheet and replaces it with straight transverse ends. This removes the source of variable fiber lengths while preserving the longitudinal structure needed for holder insertion. The fiber layer is trimmed to have uniform length across the transverse direction, ensuring consistent cleaning performance throughout the brush part.
2Shape
If the fiber layer has various lengths, then the transverse ends can be zigzag shaped, but the cleaning consistency deteriorates
Solution Approach 1:
The invention applies homogeneity by ensuring all fibers in the brush part have the same length in the transverse direction. The fiber layer is configured with uniform dimensions across the transverse direction, creating consistent cleaning characteristics throughout the cleaning sheet. This homogeneous structure eliminates the variability caused by zigzag ends and ensures predictable, reliable cleaning performance.
3Reliability
If the second brush region is longer than the first brush region, then the protruding region enhances cleaning, but the brush part complexity increases
Solution Approach 1:
The invention applies local quality by creating different brush region lengths at different locations of the cleaning sheet. The second brush region extends longer than the first brush region, creating a protruding region that provides enhanced cleaning capability in specific areas. This localized variation in fiber length allows the cleaning sheet to address different cleaning needs across its surface while maintaining overall structural simplicity.
