Vacuum Cleaner Dust Compression for Cleaner Bin Emptying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional upright type vacuum cleaners face user inconvenience due to dust and foreign substances scattering when removing collected dust from the dust collection device, as the existing methods do not effectively compress the dust, leading to volume issues and scattering during disposal.
Innovation Solution
An upright type vacuum cleaner equipped with a dust compression device that selectively changes size based on pressure changes, allowing it to compress dust within the dust collection device by communicating with either the vacuum suction motor or external atmosphere, utilizing a guide member and dust compression member to expand or contract, and a flow passage switch device to control air flow for efficient compression and release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If dust is collected in the dust collection device using conventional methods, then dust is separated and collected, but dust volume remains large causing scattering during removal
Solution Approach 1:
The dust collection device incorporates a compression mechanism that changes the physical state of dust by applying pressure, reducing its volume and density. This parameter change allows dust to be compacted into a smaller space, preventing scattering during removal while maintaining collection capacity
Solution Approach 2:
A compression mechanism acts as an intermediary between the dust collection chamber and the removal process. This intermediary device compresses dust before removal, creating a compact form that is easier to handle and less prone to scattering, thus improving ease of operation
2Ease of operation
If dust compression device is added to reduce dust volume, then dust removal convenience is improved, but device complexity increases
Solution Approach 1:
The compression mechanism is integrated into the existing dust collection device, allowing it to perform both dust collection and dust compression functions. This multi-functionality reduces the need for separate components, thereby minimizing the increase in device complexity while still improving dust removal convenience
Solution Approach 2:
The compression mechanism is merged with the dust collection chamber and removal system, creating an integrated unit. By combining these functions into a single system rather than separate components, the overall device complexity is minimized while achieving the goal of easier dust removal
