Hinged Vacuum Bag Mounting Plate for Secure Port Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaner bag attachment systems often rely on complex mechanisms or friction fits, which can be inefficient and difficult to use, especially when securing and removing the bag from the suction port.
Innovation Solution
A vacuum bag attachment device featuring a holding plate with a hinged portion and apertures that securely engages with the suction port's projection, allowing for easy attachment and detachment by aligning and folding the hinged portion over the projections adjacent to the suction port.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a friction fit or complex automatic positioning system is used to secure the attachment device to the suction port, then the bag can be secured, but the device complexity increases and ease of operation decreases
Solution Approach 1:
The attachment device is segmented into a holding plate with a first aperture for the suction port and a hinged portion with a second aperture for the fixation projection. This segmentation allows each part to perform its specific function independently, simplifying the overall structure while maintaining secure attachment through the coordinated action of both apertures
Solution Approach 2:
The hinged portion automatically positions itself to engage with the fixation projection when the bag is inserted. The hinge mechanism provides self-aligning capability, eliminating the need for complex automatic positioning systems while ensuring reliable engagement between the second aperture and the projection
2Reliability
If a friction fit or complex automatic positioning system is used to secure the attachment device, then the bag can be attached, but ease of operation deteriorates
Solution Approach 1:
The attachment device is divided into a holding plate and a hinged portion, each with dedicated apertures. This segmentation creates a straightforward attachment sequence: insert the suction port through the first aperture, then the hinge automatically positions the second aperture to engage with the fixation projection, making the operation simple and intuitive
Solution Approach 2:
The hinged portion is designed to be movable, allowing it to flex and automatically align with the fixation projection during insertion. This dynamic characteristic enables the user to simply push the bag in without needing to manually align multiple components, significantly improving ease of operation while maintaining secure attachment

AI summary
A vacuum bag (10) attachment device and method. One embodiment provides a device for attaching a vacuum bag to a suction port of a vacuum cleaner (11), wherein the vacuum cleaner has a fixation projection (22) positioned adjacent the suction port (17). The attachment device comprises a holding plate (12) having a first aperture (15) configured and adapted to be received on the suction port of the vacuum. The holding plate also has a hinged portion (18) with a second aperture (21) positioned within the hinged portion. The hinged portion is moveable between a first position in which the hinged portion does not secure the holding plate to the vacuum and a second position in which the hinged portion secures the holding plate to the vacuum. The second aperture is configured and dimensioned to be received on the projection (22) adjacent the suction port of the vacuum cleaner when the hinged portion is in the second position.
