Vacuum Attachment With Air Jet Dust Removal for Delicate Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vacuum cleaners and dusters are ineffective in removing dust and debris from surfaces with small items or hard-to-reach areas without displacing the items, as they either fail to capture dust or require physical contact and removal of items, and cannot efficiently clean delicate or difficult-to-reach surfaces.
Innovation Solution
A vacuum attachment device that combines a pressurized air source with a vacuum airflow path to dislodge dust and debris from surfaces while capturing it, allowing for touch-free cleaning without the need to remove items, using a body with a vacuum adaptor and dispensing airflow path connected to a conventional vacuum cleaner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a typical vacuum cleaner is used to remove dust from surfaces with small items, then dust can be captured, but the vacuum cannot dislodge dust stuck to surfaces and requires contact that may knock over items
Solution Approach 1:
The device merges a pressurized air source and a vacuum cleaner into a single integrated system. The pressurized air dislodges dust from surfaces while the vacuum simultaneously captures the dislodged dust, achieving both non-contact operation and effective dust removal without knocking over items.
Solution Approach 2:
The pressurized air performs preliminary action by dislodging dust from surfaces before the vacuum captures it. This preliminary dislodging action enables the vacuum to effectively capture dust that would otherwise be stuck to surfaces, improving overall dust removal effectiveness without requiring physical contact.
2Ease of operation
If typical dusters are used to remove dust, then dust can be moved, but the dust is not captured and merely moved around
Solution Approach 1:
The device combines a pressurized air source that dislodges dust with a vacuum cleaner that captures dust in the same operational flow. This merging ensures that dust is not merely moved around like with traditional dusters, but is actively captured and removed from the environment, eliminating the harmful effect of dust redistribution.
3Productivity
If items on a surface are removed before cleaning, then dust can be effectively removed from the surface, but the cleaning process becomes tedious and time-consuming
Solution Approach 1:
The cleaning function is segmented into two simultaneous actions: pressurized air dislodges dust from surfaces and items, while the vacuum captures the dislodged dust. This segmentation allows cleaning to proceed without removing items, as the pressurized air can reach around and between items to dislodge dust that the vacuum then captures.
Solution Approach 2:
By merging the pressurized air source and vacuum cleaner into a single device, the system enables simultaneous dislodging and capturing of dust. This allows effective dust removal from surfaces with items present, eliminating the need to remove and reposition items and thus saving time while maintaining dust removal effectiveness.
4Productivity
If a pressurized air source is added to a vacuum cleaner, then dust can be dislodged and captured simultaneously, but the device complexity increases
Solution Approach 1:
The patent merges a pressurized air source and a vacuum cleaner into a single integrated device with common components such as the housing, handle, and control mechanisms. This merging enables simultaneous dust dislodging and capturing while minimizing the increase in device complexity through shared structural elements.
