Vacuum Dirt Sack Shutter for Dust-Free Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for closing dirt sacks in suction apparatuses require manual operation, exposing users to dust and impurities, and involve inconvenient sack replacement processes with a risk of dust leakage.
Innovation Solution
A device with a container and drive means that allows automatic closure of the sack using a shutter element and attachment mechanisms, enabling the sack to be replaced quickly and hygienically without user contact with dust, utilizing a pivoted lid and shutter element that automatically seals the sack as it is lifted and falls into a collection container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used to close the sack hole, then the closing function is achieved, but user exposure to dust and impurities occurs
Solution Approach 1:
The system performs the closing action automatically through self-service mechanisms. The shutter element is automatically positioned to close the hole when the sack is removed, and the attachment means automatically detach and reattach during sack replacement, eliminating the need for manual user intervention and thus preventing dust exposure.
Solution Approach 2:
The closing action is performed in advance before the user needs to handle the sack. The shutter element is pre-positioned to close the hole automatically when the sack is removed, so the harmful dust is sealed before any user contact occurs.
2Productivity
If manual operation is used to release and replace the sack, then the replacement function is achieved, but the operation becomes inconvenient and dust leakage risk increases
Solution Approach 1:
The attachment means automatically detach from the container when the lid is opened and automatically reattach when the lid is closed, performing the sack replacement function without requiring manual user manipulation. This self-service mechanism both speeds up the process and eliminates inconvenience.
Solution Approach 2:
The attachment and detachment actions are prepared and executed automatically as preliminary steps before the user needs to handle the sack replacement, streamlining the entire process and preventing dust leakage through automated sealing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures automatic closure of the sack, preventing user exposure to dust and facilitating easy sack replacement by automatically sealing the sack and guiding it into a collection container, enhancing user safety and convenience.
Implementation Method 1
closing means mounted sliding on said plate, able to close said first hole
Implementation Method 2
by rotating the lid by an ever-increasing angle and due to the effect of gravity, the plate and the shutter element are constrained by the corresponding attachment means
