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 and filter accessibility.
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 rotation to expose filters for cleaning, simplifying the structure and improving filter accessibility while maintaining suction 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 assembly is segmented into a removable filter unit that can be separated from the main housing. The pre-motor filter and post-motor filter are configured as detachable components that can be accessed by removing the filter unit, allowing users to clean filters without disassembling the entire vacuum cleaner housing.
Solution Approach 2:
The filters are extracted from the enclosed housing structure and placed in a removable filter unit. This allows the filters to be taken out for cleaning by simply removing the filter unit from the main body, eliminating the need to disassemble the product housing while still providing protection when the unit is 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 clearly defined, but the number of parts increases and the structure becomes complicated
Solution Approach 1:
Multiple air guidance functions are merged into the filter unit structure. The filter unit integrates the pre-motor filter, post-motor filter, and air guidance passages into a single assembled component. This reduces the number of separate parts while maintaining clear air flow paths from the cyclone to the motor and from the motor to the exhaust.
Solution Approach 2:
The filter unit is designed as a multi-functional component that simultaneously performs filtration, air guidance, and structural support functions. It guides air from the cyclone to the motor, filters air before the motor, and guides exhaust air to the post-motor filter, eliminating the need for multiple separate structures.
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
The design enhances user convenience by allowing easy filter maintenance, reduces airflow resistance, and improves suction performance by minimizing the number of parts and simplifying the air guidance system.
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.
