Self-Sealing Vacuum Cleaner Receptacle for Nuclear Dust Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners for nuclear controlled areas generate excessive waste and risk contamination when replacing dust receptacles and filters, as the filter is often discarded unnecessarily and occupies large storage volumes, and there is no efficient way to prevent dust dissemination during maintenance.
Innovation Solution
The vacuum cleaner design features a filter and dust receptacle formed from juxtaposed bodies with releasable assembly means, including a diaphragm with elastic blades and a self-sealing connection, allowing for easy separation and closure to prevent dust release, enabling reuse of the filter and reducing waste volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the filter is discarded together with the dust receptacle, then the replacement operation is simple, but the waste volume increases excessively
Solution Approach 1:
The filter assembly is segmented into two separable parts: the filter element and the receptacle. The filter can be detached from the receptacle through a breaking operation, allowing the filter to be reused while only the contaminated receptacle is discarded. This segmentation directly reduces waste volume while maintaining operational simplicity.
2Reliability
If the filter is made large to ensure adequate filtration, then filtration performance is improved, but the storage container occupation becomes poor and waste volume increases
Solution Approach 1:
By separating the filter from the receptacle, the filter can be optimized for filtration performance without being constrained by the need to accommodate storage considerations. The filter element can be designed with appropriate size and shape for effective filtration, while the receptacle handles the storage function. This segmentation allows each component to be optimized independently.
3Ease of repair
If the dust receptacle is disassembled for replacement, then the filter can be accessed, but dust dissemination risk increases
Solution Approach 1:
The filter is extracted as a separate component that can be removed from the receptacle through a breaking operation. This allows the filter to be accessed and replaced independently without requiring full disassembly of the dust receptacle, thereby minimizing the risk of dust dissemination while maintaining ease of repair.
4Device complexity
If the filter and receptacle are permanently joined, then assembly simplicity is improved, but filter replacement and reuse become difficult
Solution Approach 1:
The connection between the filter and receptacle is designed to be dynamic rather than permanent. The breaking operation allows the filter to be detached from the receptacle when needed, providing a balance between assembly simplicity and ease of replacement. The system transitions from a permanently joined state to a separable state based on operational requirements.

Function Achieved in This Case
This design facilitates efficient replacement and reuse of the filter, minimizing waste generation and ensuring safe handling and storage of contaminated materials, while maintaining the vacuum cleaner's tightness to prevent dust release outside controlled environments.

AI summary
This vacuum cleaner comprises, in addition to a motor (1), a filter (2) and a dust container (3) that are arranged so that, when they are assembled, a conical end-fitting (12) at the bottom of the filter body (10) opens a diaphragm (16) formed from elastic strips (17) located at the top of the container body (13) and establishes communication between the filter and the container, thereby making it possible for dust to be freely sucked into and deposited in the bottom of the container (3). When, in contrast, they are separated, the strips of the diaphragm straighten out and clo wall se the container body (13), thereby preventing dust sucked up by the vacuum cleaner from dispersing.
