Cleaning Sheet Brush Layout for Uniform Fiber Dust Pickup
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 brush region is longer and protrudes, enhancing cleaning efficiency by ensuring consistent fiber length and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the cleaning article 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 applies local quality by creating a brush part with spatially varying fiber lengths. The fiber assembly includes a first region with shorter fibers and a second region with longer fibers that protrude beyond the first region. This local differentiation allows different areas of the cleaning article to have optimized fiber lengths for their specific cleaning needs, resolving the contradiction between shape design and cleaning effectiveness.
2Reliability
If fibers have uniform length and orientation, then cleaning effectiveness improves, but manufacturing complexity increases
Solution Approach 1:
The invention applies segmentation by dividing the fiber assembly into distinct regions with different fiber length characteristics. The brush part is segmented into a first region and a second region, where the second region contains longer fibers that protrude. This segmentation allows for controlled manufacturing processes that can create different fiber length zones while maintaining overall uniformity within each zone, balancing cleaning effectiveness with manufacturing feasibility.
