Vacuum Cleaner Filter Bag Pivot Mounting for Jam-Free Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaner designs require precise alignment and are prone to jamming and debris accumulation, making filter bag exchange difficult and cumbersome.
Innovation Solution
A strap-shaped filter mounting plate with pivot members that engage with corresponding receivers on the vacuum cleaner housing, allowing the filter bag to pivot into a secure position, eliminating the need for precise alignment and reducing debris accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If slide channels are used as receivers for the filter mounting plate, then the filter bag can be positioned and held in the bag compartment, but the filter mounting plate requires precise alignment and careful sliding, and the channels accumulate dust and debris causing jamming
Solution Approach 1:
Instead of sliding the filter mounting plate horizontally into slide channels, the invention inverts the motion to a vertical dropping motion where the filter mounting plate drops straight down into the bag compartment. The pivot members rotate vertically from an insertion position to a final position, eliminating the need for precise lateral alignment and avoiding horizontal channels that accumulate dust.
Solution Approach 2:
The invention introduces a dynamic pivoting motion mechanism where the filter mounting plate with pivot members rotates from an insertion position to a final position. This dynamic motion allows the filter mounting plate to self-align and settle into place, making the installation process more tolerant of alignment variations and less prone to jamming.
2Reliability
If slide channels are used as receivers for the filter mounting plate, then the filter bag can be positioned in the bag compartment, but the channels become clogged with dust and debris making the filter mounting plate difficult to slide
Solution Approach 1:
The invention inverts the receiver design from horizontal slide channels to vertical pivot receivers. The pivot receivers are simple vertical openings that guide the pivot members during rotation, eliminating the complex horizontal sliding mechanism that accumulates dust and requires precise alignment.
Solution Approach 2:
The invention extracts the filter mounting plate from the horizontal sliding path and repositions it for vertical insertion and pivoting. This extraction from the dust-prone horizontal channel environment simplifies the receiver arrangement to basic vertical guides and pivot points, reducing complexity and maintenance requirements.
3Manufacturing precision
If precise alignment is required for the filter mounting plate with slide channels, then the filter bag can be properly positioned, but the installation process becomes time-consuming and difficult
Solution Approach 1:
The dynamic pivoting motion allows the filter mounting plate to self-align during rotation. The pivot members naturally guide the plate into the correct position as they rotate from insertion to final position, eliminating the need for precise pre-alignment and significantly reducing installation time.
Solution Approach 2:
By inverting from horizontal sliding to vertical pivoting, the system eliminates the alignment sensitivity inherent in lateral sliding mechanisms. The vertical drop and rotate motion is inherently more tolerant of position variations, allowing quick installation without time-consuming alignment adjustments.

AI summary
A filter bag of a vacuum cleaner has a filter mounting plate that includes a generally strap-shaped securing element with pivot members on an end thereof. A housing of the vacuum cleaner defines a filter bag compartment therein and has pivot receivers into which the pivot members can be substantially vertically inserted. Then the filter mounting plate can be pivoted into a substantially horizontal installed position as the filter bag is inserted into the filter bag compartment. In the installed position, a first stop member of the filter mounting plate contacts and is stopped by a second stop member of the housing so as to prevent further pivoting and so as to properly position and hold the filter mounting plate.
