Removable Vacuum Filter Tray for Easy Exterior Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum filters, particularly in industrial shop vacuums, are cumbersome and messy to clean and replace due to their attachment directly to the vacuum head, requiring disassembly for access.
Innovation Solution
A removable filter tray accessible from the exterior of the vacuum housing, angled between 10 and 30 degrees, allows for easy cleaning and replacement without disassembling the vacuum, with an electric motor and impeller orientation adjusted to accommodate the angled tray, ensuring a sealed connection and efficient airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the filter is attached directly to the vacuum head, then the vacuum structure is compact, but the filter cleaning and replacement becomes cumbersome and messy
Solution Approach 1:
The filter assembly is segmented from the vacuum head by introducing a removable filter tray that can be independently accessed. The filter tray is disposed in the airflow path between the suction inlet opening and the vacuum pressure source, allowing the filter to be removed and cleaned without disassembling the vacuum head itself.
Solution Approach 2:
The filter is extracted from its traditional position within the vacuum head and placed on a removable tray that can be accessed from the exterior of the housing. This extraction allows the filter to be removed entirely from the vacuum assembly for easy cleaning without requiring disassembly of the vacuum head.
2Ease of operation
If the filter tray is made removable and accessible from exterior, then filter maintenance becomes easy, but the vacuum housing structure becomes more complex
Solution Approach 1:
The housing structure is segmented to include a removable filter tray assembly that can be independently accessed from the exterior. The filter tray is disposed in the airflow path between the suction inlet opening and the vacuum pressure source, creating a modular component that simplifies maintenance while adding structured complexity to the housing.
3Productivity
If the filter tray is angled between 10 and 30 degrees, then the motor and impeller orientation can be optimized, but the overall vacuum height may increase
Solution Approach 1:
The filter tray is positioned at an asymmetric angle between 10 and 30 degrees relative to horizontal, rather than being parallel to the base. This asymmetric orientation allows the motor and impeller to be disposed in the housing at corresponding angles, optimizing the airflow path and vacuum performance while managing the overall height profile.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easy and mess-free cleaning and replacement of the filter tray, reducing user effort and maintaining vacuum performance while minimizing the overall height and noise of the vacuum.
Implementation Method 1
A vacuum pressure source is disposed in the housing for providing a vacuum pressure to the suction inlet opening
Implementation Method 2
A removable filter tray accessible from the exterior of the housing is disposed in an airflow path between the suction inlet opening and the vacuum pressure source
Data Source
AI summary
A vacuum is provided with a removable filter tray that allows a user to access the filter without having to disassemble the vacuum. The filter can then be changed or cleaned and easily replaced without disassembly of the vacuum.
