Cleaning Sheet Fiber Layout for Guided Dust Capture
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 with a fiber assembly oriented in a specific direction, including first and second contact regions, where the second contact region is lower than the first, forming a guide region to direct dust to the first contact region, enhancing cleaning efficiency.
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 cleaning length
Solution Approach 1:
The cleaning sheet is divided into distinct functional regions: a first contact region with longer fibers for primary cleaning, a second contact region with shorter fibers for secondary cleaning, and a guide region with even shorter fibers to direct debris. This segmentation allows each region to perform its specific function optimally without the entire sheet being limited by the shortest fiber length.
Solution Approach 2:
Different regions of the cleaning sheet are given different fiber length characteristics tailored to their specific functions. The first contact region has longer fibers for effective soil removal, while the guide region has shorter fibers for directing debris, ensuring that each local area has the appropriate quality for its role in the cleaning process.
2Reliability
If the second contact region is made lower than the first contact region, then dust is guided to the first contact region, but the structure becomes more complex
Solution Approach 1:
The cleaning sheet transitions from a two-dimensional planar structure to a three-dimensional structured surface by creating height differences between the first contact region, second contact region, and guide region. This dimensional change enables the guide region to effectively direct dust toward the first contact region while maintaining a relatively simple overall structure.

AI summary
To provide a cleaning tool exhibiting excellent cleaning effectiveness. The present invention relates to a cleaning tool comprising a cleaning sheet, and a holding tool for holding said cleaning sheet. The cleaning sheet is provided with: a brush part capable of cleaning an object to be cleaned; a base part; and insertion parts for the holding tool. The brush part is provided with a first contact region and a second contact region. The second contact region is provided with a lower region formed so as to be lower than the first contact region in the thickness direction. The lower region is used as a guide region capable of guiding dust on the object to be cleaned towards the adjacent first contact region.
