Collapsible Vacuum Filter Design for Reusable Debris Collection
Solution Overview
Problem
Conventional vacuum cleaners face inefficiencies in debris collection and filtration, as they either require disposable dust bags or reusable cyclones and dust bins, with no effective solution for a collapsible and expandable filter that can automatically adapt to fluid flow and debris accumulation.
Innovation Solution
A collapsible filter design that includes upper and lower housings and filter media, which can automatically expand when installed, using air pressure, gravity, or mechanical means, allowing for efficient debris collection and storage within a defined inner volume, and can be easily installed and removed without releasing debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a conventional dust bag is used to collect debris, then debris collection is achieved, but the bag must be discarded and replaced once full, increasing loss of substance and device complexity
Solution Approach 1:
The filter media is designed to dynamically change volume, collapsing to a compact form for storage and transport, then automatically expanding to a large operational volume when installed in the vacuum cleaner. This dynamic transformation allows a single reusable filter to provide large debris capacity while maintaining compact storage, eliminating the need for disposable bags.
Solution Approach 2:
The filter media is collapsed into a compact form that nests within the housing during storage and transport. When installed, the filter automatically expands from this nested compact state to its full operational size, maximizing debris capacity while minimizing storage volume.
2Quantity of substance
If a cyclone and dust bin are used to collect debris, then debris collection is achieved, but the system requires disposal and reuse of the bin, increasing device complexity and loss of time
Solution Approach 1:
The filter provides a fixed, sealed debris collection environment where debris is trapped within the filter media structure. The filter remains in place until needed for maintenance, eliminating the frequent disposal and replacement cycles associated with dust bins, thereby reducing time loss.
Solution Approach 2:
The filter is designed as a long-lasting reusable component that can be removed and cleaned as a single unit when full. This eliminates the need for frequent disposal and replacement, reducing both time loss and the complexity associated with dust bin systems.
3Ease of operation
If the filter is designed to be collapsible and expandable, then ease of operation and storage is improved, but device complexity increases
Solution Approach 1:
The filter automatically expands from its collapsed state to its operational state upon installation in the vacuum cleaner, utilizing the system's airflow or structural features to trigger expansion. This self-expanding mechanism eliminates the need for complex manual expansion devices while providing ease of installation and removal.
Solution Approach 2:
The filter is designed as a separable component that can be easily removed from the vacuum cleaner housing for cleaning and maintenance. The modular design allows the filter to be handled as a discrete unit, simplifying installation and removal operations despite the collapsible structure.
4Quantity of substance
If the filter automatically expands to accommodate debris, then debris collection capacity is improved, but manufacturing precision requirements increase
Solution Approach 1:
The filter media employs flexible material that can transition between collapsed and expanded states. This flexibility allows the filter to accommodate varying debris volumes while using simpler manufacturing processes, as the flexible material naturally conforms to the required geometric transitions without requiring high-precision rigid structures.

AI summary
A filter configured to separate debris from a flow of fluid. The filter includes a housing and a filter media coupled to the housing to form a collection container. The collection container is configured to store debris separated by the filter media from a flow of fluid. The filter further includes an inlet opening that extends through the housing to provide fluid communication into the collection container such that the flow of fluid with the debris can flow into the collection container and a relatively clean flow of fluid exits through the filter media. The filter further includes an attachment member that couples the filter media to the housing.
