Cleaning Sheet Structure With Rigid Scraping Strips for Dust Removal

Solution Overview

Problem

The existing cleaning article with a zigzag shape at its transverse ends struggles to fully exert its scraping function due to fiber entanglement, limiting its cleaning effectiveness.

Innovation Solution

A cleaning tool featuring a cleaning sheet with alternating first and second strips of varying rigidity, where the second strips have a high rigidity region for effective dust scraping, and a holder for securely attaching the sheet, allowing efficient dust removal without fiber entanglement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fiber layer is used for cleaning, then the cleaning article can adhere to and remove dust, but the fibers become entangled and the scraping function is compromised

Engineering Contradiction:

Improvecleaning functionVSAvoidfiber structure

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The cleaning article is divided into distinct functional zones: a fiber layer for adhesion and a separate scraping layer with protrusions for mechanical scraping. This segmentation prevents fiber entanglement from compromising the scraping function, as each layer performs its designated task independently.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cleaning article combines different material types and structures: a flexible fiber layer made of soft material for dust adhesion, and a rigid scraping layer with protrusions made of harder material for effective scraping. This composite structure allows both functions to coexist without interference.

Inventive Principle:

Principle #40Composite materials

If strips of varying rigidity are used, then scraping effectiveness is improved, but device complexity increases

Engineering Contradiction:

Improvecleaning effectivenessVSAvoidstrip structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The cleaning sheet is divided into multiple strip elements with different rigidity characteristics, allowing each strip to be optimized for specific scraping tasks while maintaining overall structural integrity through a modular design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the cleaning sheet have strips with locally optimized rigidity properties. Some strips are more rigid for scraping stubborn deposits, while others are more flexible for general cleaning, allowing each area to perform its specific function effectively.
