Vacuum Cleaner Filter Bag Hinge Adapter for Visible Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adapter devices for connecting vacuum cleaner filter bags to holding devices often obscure the elements to be connected, making assembly difficult due to the design of collars and rings that cover the connection points.
Innovation Solution
An adapter device featuring a connecting device with a hinge arm and a mating connection device that form a hinge, allowing for pivoted assembly without obscuration, combined with a snap connection mechanism for secure attachment, and a sealing element to prevent air leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a collar and ring design is used for connection, then the connection structure is formed, but the elements to be connected are obscured making assembly difficult
Solution Approach 1:
The connection device is divided into separate components: a connecting device with a first plate and a mating connection device with a second plate. These segments can be assembled independently without obscuring each other's connection elements, allowing the hinge arm and hinge counterpart to engage while maintaining visibility of alignment features.
Solution Approach 2:
The connection transitioned from a planar collar-and-ring design to a three-dimensional hinge mechanism. The hinge arm pivots relative to the hinge counterpart, creating a rotational degree of freedom that allows assembly from multiple angles while keeping connection elements visible during the pivoting process.
2Adaptability or versatility
If adapter plates are provided for different vacuum cleaners, then adaptability to different holding devices is achieved, but device complexity increases
Solution Approach 1:
The adapter device employs a universal connecting device with a standardized hinge mechanism that can interface with multiple types of holding devices. The first plate and second plate design allows the same adapter to work with different vacuum cleaner models, reducing the need for multiple specialized adapter plates while maintaining compatibility across various holding device types.

AI summary
The adapter has a connection device with a first plate (11) with a through opening (12) for an air flow and a hinge arm, a counter connection arrangement with a second plate with a through opening for an air flow and a hinge counter piece, whereby the hinge arm and then counter piece are formed so that a hinge is formed by their interaction. An independent claim is also included for a vacuum cleaner filter bag,.
