Cleaning Tool Head with Line-Shaped Ribs for Improved Dust Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning tools with ribs or projections on the back-side of the head part, such as dot-shaped or fine projections, fail to sufficiently support the cleaning sheet, resulting in inadequate dust collection properties.
Innovation Solution
A cleaning tool with a head part formed in a rectangular shape, featuring line-shaped ribs that incline from the central part to the edge, including oblique-line and rhombus-shaped ribs, which are convex and recessed to enhance dust collection by varying contact with the floor surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dot-shaped or fine projections are provided on the back-side of the head part, then the structure is simple, but the cleaning sheet cannot be supported sufficiently and dust collection property is not improved
Solution Approach 1:
The head part is segmented into multiple functional regions: a flat pressure-applied part for homogeneous contact, and multiple raised parts with line-shaped ribs for non-homogeneous contact. This segmentation allows different regions to perform different functions - the flat part provides stable pressure distribution while the raised parts with ribs create varied contact patterns to improve dust collection efficiency
Solution Approach 2:
Different regions of the head part are given different local qualities: the pressure-applied part has a flat surface for uniform pressure, while the raised parts have line-shaped ribs that protrude to create non-homogeneous contact. This local differentiation allows the cleaning sheet to contact the floor surface in varied ways, improving dust collection while maintaining structural simplicity
2Reliability
If the entire surface of the head part pushes onto the floor surface homogeneously, then the structure is simple, but the dust collection property is not improved
Solution Approach 1:
The head part incorporates both homogeneous and non-homogeneous contact regions: a flat pressure-applied part for homogeneous contact and raised parts with line-shaped ribs for non-homogeneous contact. This local quality differentiation allows the cleaning sheet to contact the floor in varied ways, improving dust collection efficiency without complicating the overall structure
3Reliability
If line-shaped ribs are provided instead of dot-shaped projections, then the cleaning sheet support is improved, but the head part structure becomes more complex
Solution Approach 1:
The head part is divided into a flat pressure-applied part and multiple raised parts with line-shaped ribs. This segmentation provides sufficient cleaning sheet support through the raised parts while keeping the overall structure relatively simple by using a modular design approach
Solution Approach 2:
The design changes the geometric parameters of the support structures from dot-shaped projections to line-shaped ribs on raised parts. This parameter change increases the surface area and support capability for the cleaning sheet while maintaining manufacturing simplicity through standard molding techniques
