Manual Dust Collector With Rotating Trap for Quiet Tight-Space Cleaning

Solution Overview

Problem

Conventional manual cleaning instruments face challenges such as difficulty in disposing of collected dust, limited access to tight spaces, noise, and vibration during use, and the generation of waste like adhesive tape.

Innovation Solution

A manual cleaning instrument with a base, a hollow dust trapping body that revolves, and front and rear dust removal bodies with brushes, along with a handle and buffer member to restrict noise, and a lid for easy dust discharge, and optionally, wheels for reduced vibration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If adhesive tape is used to collect dust, then dust collection is effective, but the instrument cannot move smoothly in tight spaces and adhesive tape waste is generated

Engineering Contradiction:

Improvedust collection effectivenessVSAvoidmovement smoothness in tight spaces

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The invention extracts and eliminates the adhesive tape component from the dust collection mechanism. Instead of using adhesive tape, the patent employs a dust collection chamber with opening/closing means that allows dust to be collected and disposed of without adhesive materials, thereby enabling smooth movement in tight spaces while maintaining dust collection effectiveness

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention implements a dust collection chamber with opening/closing means that allows for easy disposal of collected dust. The chamber can be opened to discharge dust and closed during operation, enabling efficient dust removal without generating adhesive tape waste and allowing easy disposal of collected detritus

Inventive Principle:

Principle #34Discarding and recovering

2Reliability

If adhesive tape is used to collect dust, then dust collection is effective, but the overall amount of detritus increases due to the tape itself

Engineering Contradiction:

Improvedust collection effectivenessVSAvoidoverall detritus amount

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The invention extracts and eliminates the adhesive tape component from the dust collection mechanism. Instead of using adhesive tape, the patent employs a dust collection chamber with opening/closing means that allows dust to be collected and disposed of without adhesive materials, thereby enabling smooth movement in tight spaces while maintaining dust collection effectiveness

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention implements a dust collection chamber with opening/closing means that allows for easy disposal of collected dust. The chamber can be opened to discharge dust and closed during operation, enabling efficient dust removal without generating adhesive tape waste and allowing easy disposal of collected detritus

Inventive Principle:

Principle #34Discarding and recovering

3Reliability

If the instrument is moved back and forth to clean, then dust collection is possible, but noise and vibration are generated

Engineering Contradiction:

Improvedust collection capabilityVSAvoidnoise and vibration

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention introduces buffer members that contact the dust collection chamber to cushion and restrict its movement. These buffer members absorb shocks and vibrations during operation, preventing noise and vibration from being generated while allowing the dust collection function to operate effectively

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

4Volume of moving object

If a roll of adhesive tape is used, then the instrument is compact and easy to store, but the tape adheres to surrounding articles in tight spaces

Engineering Contradiction:

Improveinstrument compactnessVSAvoidadhesion to surrounding articles

Core Design Contradiction:

Volume of moving objectVSEase of operation

Solution Approach 1:

The invention extracts and eliminates the adhesive tape component from the dust collection mechanism. Instead of using adhesive tape, the patent employs a dust collection chamber with opening/closing means that allows dust to be collected and disposed of without adhesive materials, thereby enabling smooth movement in tight spaces while maintaining dust collection effectiveness

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

To provide a compact manual cleaning instrument with which it is simple to collect and discharge dust, with which it is possible to clean in tight spaces, which is silent, and which is comfortable to use. A dust trapping body 3 is brought into contact with a surface to be cleaned, and the manual cleaning instrument 1 is moved back and forth, whereby dust can be trapped and collected in a dust collection chamber 37. The dust which has been collected can be discharged by opening a lid 28.
