Handheld Vacuum Cleaner Filter Unit Design for Easy Maintenance Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld vacuum cleaners have complex structures that make it difficult for users to clean the filters, as they require disassembly and reassembly to access and clean the pre-motor and post-motor filters, leading to reduced suction ability due to dust accumulation.
Innovation Solution
A cleaner design that allows for easy separation and cleaning of the filter unit, which can be coupled and decoupled from the main body by rotation, with the filter unit protruding outward for easy access and maintenance, reducing the number of parts and simplifying the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pre motor filter is disposed between the airflow generator and the cyclone and surrounded by a housing, then the filter is protected, but it requires disassembly of the product to access the filter for cleaning
Solution Approach 1:
The filter assembly is segmented from the main housing, allowing the filter to be accessed and removed independently without disassembling the entire product. The filter is positioned in a detachable module that can be separated from the housing.
Solution Approach 2:
The filter is extracted from the enclosed housing structure and positioned in a location that is easily accessible to users. The filter assembly can be removed from the device without requiring disassembly of protective housing components.
2Reliability
If separate structures are provided for guiding air from the cyclone to the motor and from the motor to the post motor filter, then air flow paths are defined, but the number of parts increases and the structure becomes complicated
Solution Approach 1:
Multiple air flow guiding functions are merged into a single integrated structure. The housing or main body component performs multiple functions: it guides air from the cyclone to the motor, supports the motor, and directs air to the post-motor filter, eliminating the need for separate guiding structures for each path.
Solution Approach 2:
The main housing or body structure is designed as a multi-functional component that simultaneously serves as an air flow guide, structural support, and filter mounting structure, reducing the overall number of parts while maintaining proper air flow control.

Function Achieved in This Case
Facilitates easier filter maintenance, improves suction efficiency by preventing dust accumulation, and enhances user convenience by simplifying the cleaning process without the need for extensive disassembly.
Implementation Method 1
a suction motor that is disposed in the main body and generates suction force
Implementation Method 2
an exhaust filter for filtering air discharged from the suction motor

AI summary
A cleaner includes: a main body that has an opening; a suction motor that is disposed in the main body and generates suction force; and a filter unit that includes an exhaust filter for filtering air discharged from the suction motor, the filter unit being inserted into the main body through the opening and being separated from the main body, wherein when the filter unit is combined with the main body, a portion of the filter unit protrudes out of the main body, and a portion of the exhaust filter is positioned inside the main body and the other portion of the exhaust filter is positioned outside the main body.
