Filter Bag Mounting Panel With Hinged Tab for Low Air Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter bag attachment mechanisms for vacuum cleaners are inefficient in securing the filter bag to the fill tube, leading to air resistance issues and instability during operation.
Innovation Solution
A filter bag with a panel having two hinges, where the panel can be manually pivoted to secure the fill tube, utilizing a trapezoidal design with inclined side edges and a narrower bottom edge to enhance stability and ease of attachment, and elastic tabs for secure engagement with the fill tube bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple attachment mechanism is used, then the device complexity is reduced, but the reliability of securing the filter bag to the fill tube deteriorates
Solution Approach 1:
The attachment mechanism is divided into separate functional elements: a panel with hinge connection, securing tabs with elastic elements, and a bracket structure. This segmentation allows each component to perform its specific function efficiently while maintaining overall system reliability without excessive complexity.
Solution Approach 2:
The attachment mechanism incorporates movable elements including a hinge allowing panel rotation and elastic tabs that can deform during engagement. These dynamic features enable the mechanism to adapt during installation and operation, ensuring reliable securing while maintaining a relatively simple overall structure.
2Object-affected harmful factors
If the fill tube angle is optimized, then air resistance is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The fill tube angle is optimized as a specific geometric parameter to reduce air resistance. By carefully selecting and controlling this angular parameter, the design minimizes harmful aerodynamic effects while managing the associated manufacturing precision requirements through deliberate parameter selection.
3Ease of operation
If a trapezoidal panel design with inclined side edges is used, then the ease of operation is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The panel employs an asymmetric trapezoidal geometry with inclined side edges rather than a symmetric rectangular shape. This asymmetric design improves operational characteristics such as insertion ease and engagement alignment, while the specific geometric ratios are chosen to balance manufacturing precision requirements.

AI summary
A filter bag includes a bag structure of filter material. A panel is adhered to the bag structure and has a fill opening. A securing tab is attached by a hinge to the panel. The panel is configured to have a mounted position in which a fill tube projects through the fill opening into the bag structure to exhaust air into the bag structure. The panel can be secured in the mounted position by the attachment tab being manually pivoted about the hinge into attachment with an attachment structure coupled to the fill tube.
