Vacuum Dust Collector Latch Layout to Prevent Accidental Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of cyclonic vacuum cleaners often face difficulties in efficiently and hygienically emptying the collecting chamber due to the risk of accidentally releasing the entire chamber instead of just opening it for disposal, leading to spills and inconvenience.
Innovation Solution
A separating apparatus design where the second catch for releasing the collecting chamber from the separator is made inaccessible when the first catch for opening the closure member is engaged, ensuring the user operates the catches in the correct sequence, preventing accidental detachment of the collecting chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If both catches are made accessible simultaneously, then the user can operate either catch freely, but the user may inadvertently operate the wrong catch leading to accidental detachment of the collecting chamber
Solution Approach 1:
The patent makes the second catch dynamically inaccessible when the first catch is engaged. The second catch is positioned such that it becomes accessible only after the closure member is opened (when the first catch is disengaged). This dynamic accessibility ensures users operate catches in the correct sequence without risk of accidental detachment.
2Reliability
If the second catch is made inaccessible when the first catch is engaged, then accidental detachment is prevented, but the device complexity increases
Solution Approach 1:
The patent combines the two catch mechanisms in a spatial arrangement where the second catch is positioned behind or near the first catch. The releasing means for the second catch is integrated with the closure member structure, so that when the closure member opens, the second catch becomes accessible. This merging approach prevents accidental detachment while adding minimal complexity.
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
This design ensures that users can empty the collecting chamber efficiently and hygienically by presenting only one releasable catch at a time, preventing accidental release of the chamber and minimizing spills, thus enhancing user experience and convenience.
Implementation Method 1
an airflow in which dirt and dust is entrained enters a first cyclonic separator via a tangential inlet which causes the airflow to follow a spiral or helical path within a collecting chamber. This causes dirt and dust to be separated from the airflow.
Implementation Method 2
The base 6 is pivotably attached, by means of a hinge, to the cylindrical wall that makes up the sides of the chamber 3. When the user operates the trigger 8, the base 6 swings open and the material in the collector falls out of the collecting chamber 3.

AI summary
A separating apparatus for a cleaning appliance, such as a vacuum cleaner, includes a separator for separating dirt and dust from a fluid flow and a collecting chamber arranged to collect dirt and dust separated by the separator. A first catch for opening a closure member on the collecting chamber is provided, with first releasing means for releasing this catch. There is also provided a second catch for releasing the collecting chamber from the separator and second releasing means for releasing the second catch. The second releasing means is inaccessible when the first catch is engaged. A cover associated with the first releasing means obscures the second releasing means until the first catch has been released. The invention prevents the user from accidentally releasing the collecting chamber from the separator when it was the user's intention simply to empty dirt and dust from the collecting chamber.
