Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate structures are provided for guiding air from cyclone to motor and from motor to post motor filter, then air flow guidance is achieved, but the number of parts increases and structure becomes complicated
Solution Approach 1:
The patent combines the functions of guiding air from cyclone to motor and from motor to post-motor filter into a single integrated flow guide structure. This flow guide simultaneously defines both air passages, eliminating the need for separate guiding structures and reducing overall part count while maintaining proper airflow control throughout the system.
Solution Approach 2:
The flow guide is designed as a multi-functional component that performs multiple air guidance tasks. It creates the air passage from the cyclone chamber to the motor, and also forms the air passage from the motor to the post-motor filter, thereby serving universal air guidance functions with a single structure.
2Ease of operation
If pre motor filter is surrounded by housing and disposed between airflow generator and cyclone, then filter protection is achieved, but filter accessibility for cleaning becomes difficult
Solution Approach 1:
The housing is segmented into removable parts, specifically the dust container can be detached to provide access to the pre-motor filter. This segmentation allows the filter to remain protected during normal operation while being easily accessible for cleaning by simply removing the dust container rather than disassembling the entire housing.
Solution Approach 2:
The dust container serves as an intermediary component that, when removed, provides access to the pre-motor filter. This mediator approach allows users to clean the filter without directly dismantling the housing structure, maintaining both protection and accessibility.
3Volume of moving object
If multiple separate structures are used for air passages, then air flow control is precise, but the cleaner size increases and compactness is reduced
Solution Approach 1:
Multiple air passage functions are merged into a single flow guide structure. The flow guide simultaneously defines the air passage from cyclone to motor and the air passage from motor to post-motor filter, reducing the overall volume required for multiple separate structures while maintaining precise airflow control through integrated design.
