Handheld Vacuum Filter Housing for No-Touch Debris Disposal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld vacuum cleaners require users to touch or grasp dirty filter bags to disconnect and dispose of them, which is undesirable due to the dirt and debris inside.
Innovation Solution
A handheld vacuum cleaner design featuring a filter with an outer housing that is removable without direct contact, using a porous structure and tabs to pull the filter away from the main body, allowing for disposal without touching the filter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the filter bag is made removable for disposal, then the vacuum cleaner can be maintained and reused, but the user must directly touch or grasp the dirty filter bag which causes hygiene issues
Solution Approach 1:
The outer housing serves as an intermediary component that the user interacts with instead of the dirty filter bag. The housing includes a release mechanism with buttons and a movable portion that enables the filter assembly to be removed without requiring the user to directly touch the filter bag containing debris
2Device complexity
If the filter is integrated into the main body, then the structure is simplified, but the filter cannot be easily removed for disposal
Solution Approach 1:
The filter assembly is segmented into distinct components: the filter bag, the filter holder, and the outer housing. This segmentation allows the entire filter assembly to be removed as a unit from the main body through a simple release mechanism, combining the benefits of integration (structural support) and separability (easy removal)
Solution Approach 2:
The release mechanism incorporates dynamic elements including movable buttons and a movable portion that transitions between locked and unlocked states. This dynamic design enables easy removal of the filter assembly by allowing the user to actuate the release mechanism, which moves the outer housing away from the main body
3Object-affected harmful factors
If a release mechanism is added to enable filter removal, then the filter can be disposed of without touching, but the device structure becomes more complex
Solution Approach 1:
The outer housing serves multiple functions: it contains the filter bag, provides structural support, and incorporates the release mechanism. The buttons and movable portion of the release mechanism are integrated into the housing structure itself, allowing the housing to perform both protective and operational functions without requiring separate components

Function Achieved in This Case
Enables users to remove and dispose of the filter without direct contact with debris, improving user convenience and hygiene.
Implementation Method 1

AI summary
A handheld vacuum cleaner including a suction inlet, a main body, a handle defined by a portion of the main body, a motor disposed within the main body operating a suction source, and a filter coupled to the main body. The filter is configured to separate debris from a low of fluid drawn through, the -suction islet The filter includes a housing forming a first volume and a filter media forming a second, inner volume. The filter media is coupled to the housing such that the first and second inner volumes together at least partially define a collection container -configured to store debris separated by the filter media from the flow of fluid. The further includes art 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 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.
