Vacuum Filter Bag Locking Rim for Leak-Free Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaner filter bag mounting systems are complex, costly, and difficult for consumers to install correctly, leading to potential dust and dirt leakage due to misalignment during installation.
Innovation Solution
A filter closure system with a locking rim and sealing assembly that securely attaches the filter bag to the vacuum cleaner housing, using a shaped lid and rim design with a gasket or projection for leak-proof alignment and easy installation, and a reusable filter bag closure clip for economical reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex mounting system with multiple components is used, then the sealing reliability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the sealing function and mounting function into a single integrated gasket component that includes both the sealing bead and the mounting flange with alignment features. This merging eliminates the need for separate sealing elements and alignment mechanisms, reducing device complexity while maintaining sealing reliability through the integrated design.
2Device complexity
If a simple mounting system is used, then the device complexity is reduced, but the alignment precision and sealing reliability deteriorate
Solution Approach 1:
The mounting flange incorporates asymmetric alignment features including a non-circular shape with specific protrusions and corresponding recesses that guide precise positioning during installation. This asymmetric design ensures correct orientation and alignment without requiring complex alignment procedures, maintaining manufacturing precision while keeping the system simple.
Solution Approach 2:
The gasket acts as an intermediary element between the filter bag and the housing, providing both sealing and alignment functions. The alignment features on the gasket's mounting flange serve as intermediate guidance structures that facilitate precise positioning during installation, ensuring proper alignment without requiring complex mounting mechanisms.
3Reliability
If a complex mounting system is used, then the sealing reliability is improved, but the ease of operation and installation difficulty worsen
Solution Approach 1:
The gasket is pre-formed with integrated alignment features and sealing structures during manufacturing, so that during installation the user simply needs to position the filter bag with the mounting flange into the housing. The alignment features automatically guide correct positioning, eliminating complex alignment steps and making installation intuitive and easy while maintaining sealing reliability.
4Reliability
If disposable filter bags with complex mounting mechanisms are used, then the sealing reliability is improved, but the loss of substance and cost increase
Solution Approach 1:
The mounting flange with alignment features is designed as a universal component that can be reused across multiple filter bag installations. The durable construction allows the mounting mechanism to be retained in the housing while filter bags are replaced, reducing material consumption and cost compared to disposable systems with integrated mounting mechanisms.

AI summary
The present invention is an improved vacuum filter or collection bag assembly for vacuum cleaners and other appliances, particularly upright vacuum cleaners. The filter bag assembly includes a filter bag with a sealing and locking rim assembly which mates with a section of the vacuum filter housing, so as to ensure proper seating and minimization of dust and dirt escaping from the filter bag during vacuum operation. The assembly may also include a gasket ring for additional sealing.
