Exhaust filter assembly for a vacuum cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners lack an effective system for easily and intuitively positioning the exhaust filter inside the vacuum cleaner body, often requiring user attention to ensure proper placement and preventing potential leakages and poor air filtering.
Innovation Solution
A vacuum cleaner with a filter frame featuring a circumferentially disposed rim that passes over a pin within the filter cavity, aided by first and second ribs on the cover that automatically guide the filter frame into position, eliminating the need for manual mounting and ensuring secure placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional filter mounting system is used, then the filter can be installed, but it requires user attention and manual positioning which may lead to incorrect placement and potential leakages
Solution Approach 1:
The filter frame automatically positions itself within the filter cavity through the interaction between the rim and pin, and the ribs on the cover that guide the filter into the correct position during closure. This self-positioning mechanism eliminates the need for manual alignment by the user, ensuring reliable placement without requiring user attention or expertise.
Solution Approach 2:
The rim and pin act as intermediary elements that facilitate the automatic positioning of the filter frame. The rim passes over the pin to guide the filter into place, while the ribs on the cover serve as intermediaries that push the filter frame into its final position. These intermediary elements ensure correct placement without requiring direct user manipulation.
2Manufacturing precision
If manual filter positioning is required, then precise placement can be achieved, but it increases device complexity and user burden
Solution Approach 1:
The positioning system serves itself through the mechanical interaction of simple elements: the rim passing over the pin and the ribs guiding the filter frame during cover closure. This self-positioning mechanism achieves precise filter placement without requiring complex adjustment mechanisms, sensors, or control systems, thereby maintaining simplicity while ensuring manufacturing precision.
Solution Approach 2:
The positioning function is segmented into distinct simple elements: the rim for initial engagement with the pin, and the ribs for final positioning during cover closure. This segmentation allows each element to perform a specific function simply, avoiding the need for a complex integrated positioning system while achieving precise filter placement.
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 allows for easy, intuitive, and leak-free positioning of the exhaust filter, reducing the risk of incorrect placement and enhancing air filtering efficiency without user intervention, ensuring effective separation of dust, odors, and bacteria from the exhaust air.
Implementation Method 1
The filter frame is pushed by the first ribs towards the filter cavity and the rim pass over the pin and next falls slightly down by the force of gravity.

AI summary
An exhaust filter (20) assembly for a vacuum cleaner comprising a filter frame (21) accommodating the filter (20) and a cover (10) pivotally mounted to a vacuum cleaner body (30) and which is pivotally between an open position and a closed position, where the cover (10) comprises at least one first rib (11) formed on an inner surface of the cover (10) for positioning the filter frame (21) into a preliminary position inside a filter cavity (33) placed in the vacuum cleaner body (30) whereas at least one second rib (12) pushes the filter frame (21) into its end position after setting the cover (10) in the closed position. The present invention provides an exhaust filter arrangement which is positions inside the vacuum cleaner body correctly without attention of the user thanks only to the existence of the set of ribs placed on the inner surface of the cover. The present invention provides an easy to use, intuitive, self-positioning exhaust filter arrangement for efficient exhaust air filtering which comes out of the vacuum cleaner during vacuuming.
