Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld vacuum cleaners require users to disassemble the device to clean filters, which is cumbersome due to complex structures and separate air guidance systems, leading to difficulties in maintaining suction efficiency as dust accumulates in filters over time.
Innovation Solution
A cleaner design with a filter unit that can be easily separated and combined with the main body, allowing for external access and cleaning without disassembling the device, featuring a protruding filter unit with internal and external filter positions to simplify maintenance and improve airflow efficiency.
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 filters for cleaning
Solution Approach 1:
The filter system is divided into a removable filter assembly that can be separated from the main housing. The filter assembly includes the pre-motor filter mounted on a frame with sealing elements, allowing it to be detached as a complete unit for cleaning while maintaining protection when installed.
Solution Approach 2:
The filter assembly is extracted from the internal housing structure and positioned to protrude externally from the cleaner body. This extraction allows users to access and remove the filter assembly without disassembling the main product housing, while the filter remains protected within its own structured assembly when installed.
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 air guidance structures are merged into the filter assembly frame itself. The frame includes integrated features that guide air from the cyclone to the motor and from the motor to the post-motor filter, eliminating the need for separate air guidance components and reducing overall structural complexity while maintaining reliable air flow paths.
3Ease of operation
If the filter unit is designed to protrude out of the main body when combined, then filter accessibility is improved, but the overall size of the cleaner increases
Solution Approach 1:
The filter assembly is designed with dynamic positioning capability, allowing it to protrude from the main body during filter maintenance operations and retract into the main body during normal cleaning operations. This dynamic adjustment optimizes both filter accessibility and compact storage, reducing the effective height of the cleaner when the filter is installed.

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.
