Solution Overview
Problem
Existing vacuum cleaners face difficulties in cleaning internal components due to complex arrangements, making it hard to disassemble and thoroughly remove accumulated foreign substances, which prolongs the cleaning process and complicates the separation of parts.
Innovation Solution
A vacuum cleaner design that allows for easy separation of the dust separation module from the body, with a filter unit and second cyclone that can be separated from each other, and a storage unit that can be rotated to facilitate quick disassembly and cleaning, using rotation restraining protrusions and grooves for secure coupling and separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the body is miniaturized to reduce size, then the vacuum cleaner becomes more compact and portable, but the internal components are complicatedly arranged in a small space making it difficult to clean and disassemble
Solution Approach 1:
The dust separation module is divided into separate components: the filter unit can be separated from the second cyclone, and the storage unit can be separated from the cyclone base. This segmentation allows each component to be accessed and cleaned independently despite the compact overall size, resolving the contradiction between miniaturization and ease of cleaning.
2Adaptability or versatility
If components are complicatedly arranged in the body, then the vacuum cleaner achieves functional integration, but it becomes difficult to expose and clean foreign substances that accumulate in the body
Solution Approach 1:
The dust separation module containing the second cyclone, filter unit, and storage unit is extracted as a separable assembly from the main body. This allows the module to be removed for thorough cleaning of accumulated foreign substances while maintaining functional integration during operation, resolving the contradiction between functional integration and cleaning accessibility.
3Ease of repair
If the vacuum cleaner structure is made separable to facilitate cleaning, then maintenance becomes easier, but the disassembly and assembly process becomes more complex and time-consuming
Solution Approach 1:
The separation mechanism is segmented into simple, independent steps: the filter unit separates from the second cyclone via a filter unit separation protrusion and groove, and the storage unit separates from the cyclone base via a storage unit separation protrusion and groove. This segmented design simplifies the disassembly process into basic separation actions, reducing complexity while maintaining ease of maintenance.
4Ease of repair
If multiple components are separated for cleaning, then thorough removal of foreign substances is achieved, but the time required for disassembly and assembly increases
Solution Approach 1:
The separation protrusions and grooves are pre-formed in the components, allowing for quick and intuitive alignment during disassembly and assembly. The filter unit separation protrusion fits into the corresponding groove, and the storage unit separation protrusion fits into its groove, enabling rapid separation without complex alignment procedures, thus reducing cleaning time while maintaining thoroughness.

AI summary
A vacuum cleaner includes a body having a space that allows air to flow therethrough. The vacuum cleaner includes a suction inlet that introduces the air into the body and a first cyclone in the body. The first cyclone separates foreign substances from the air introduced into the suction inlet. The vacuum cleaner includes a dust separation module having a filter unit that separates foreign substances from the air introduced from the first cyclone. The dust separation module also includes a second cyclone arranged within and separated from the filter unit. The second cyclone includes a cyclone base, a storage unit arranged adjacent to a lower portion of the second cyclone, and a cyclone array coupled to the cyclone base. The cyclone array allows the air to pass through an upper portion of the second cyclone and discharge the foreign substances collected by the second cyclone to the storage unit.
