Hinged Vacuum Bag Mount for Secure Suction Port Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum cleaner bag attachment methods often rely on complex systems or friction fits, which can be unreliable and difficult to secure effectively, leading to inconsistent sealing and frequent bag changes.
Innovation Solution
A vacuum bag attachment device featuring a holding plate with a hinged portion and apertures that aligns with a suction port's projection, providing a secure interference fit to attach the bag to the vacuum cleaner, allowing for easy installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a friction fit between the opening and suction port is used to secure the attachment device, then the device structure remains simple, but the attachment reliability deteriorates leading to inconsistent sealing
Solution Approach 1:
The attachment device employs a hinged portion that can rotate between a first position (parallel to holding plate) and a second position (substantially normal to holding plate), transforming the static friction fit into a dynamic mechanical engagement system that progresses from initial contact to secure locked attachment
Solution Approach 2:
The attachment device is divided into distinct functional segments: the holding plate with first aperture for initial alignment, the hinged portion with second aperture for securing, and the projecting members for final engagement with fixation projections, allowing each component to perform its specific function in sequence
2Reliability
If complicated systems with many moving parts are used to automatically position and attach the bag, then the attachment reliability improves, but the device complexity increases
Solution Approach 1:
Multiple attachment functions (alignment, securing, and locking) are merged into a single integrated hinged structure that performs all operations through one rotational motion, eliminating the need for separate moving parts while maintaining high attachment reliability
Solution Approach 2:
The hinged portion automatically transitions from the first position to the second position through user manipulation, with the projecting members self-aligning with the fixation projections on the suction port, requiring no additional actuators or complex control mechanisms
3Reliability
If a rigid attachment system is used to secure the vacuum bag, then the sealing consistency improves, but the ease of operation deteriorates making installation and removal difficult
Solution Approach 1:
The hinged portion provides dynamic movement capability, allowing the user to easily install the bag by rotating the hinge to the second position and remove it by rotating back to the first position, while maintaining rigid sealing when attached
Solution Approach 2:
The attachment mechanism is designed to be easily engaged by rotating the hinged portion to lock, and easily disengaged by reversing the rotation, providing simple bidirectional operation that maintains strong sealing during use

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.
