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 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 rotated to change its height and coupled to the main body, with the filter unit protruding to facilitate 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 housing is divided into a first housing containing the airflow generator and a second housing containing the cyclone, with the pre motor filter disposed between them. This segmentation allows the filter to be accessed by separating the two housing sections, enabling cleaning without complete disassembly while maintaining protection when assembled.
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:
The housing structure integrates multiple functions: it contains the airflow generator, supports the pre motor filter, guides air flow from the cyclone to the motor, and provides structural support for the post motor filter. By merging these separate guiding structures into the housing itself, the design reduces part count while maintaining reliable air flow control.

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.
