Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a dust bag is used in the cleaner station, then dust storage capacity is increased and dust disposal cycle is extended, but dust storage efficiency is reduced due to air flow generation from centrifugal separation
Solution Approach 1:
The dust collecting part is divided into an upper separation chamber with centrifugal separation device and a lower dust storage chamber. This segmentation allows the air flow generated by centrifugal separation to be contained in the upper chamber while the compressed dust is stored in the lower chamber, resolving the contradiction between extended dust disposal cycle and maintained dust storage efficiency.
2Shape
If the cleaner station is covered with a transparent cover to prevent dust collection state exposure, then appearance is improved, but user convenience in checking dust levels is reduced
Solution Approach 1:
A display unit is introduced as an intermediary device that translates the dust collection state into visual information. The display unit displays warning notifications in multiple levels based on the calculated dust collection amount, allowing users to check dust levels without opening the station, thus maintaining both appearance and user convenience.
3Device complexity
If dust collection amount is not accurately measured, then system complexity is reduced, but user awareness of dust levels and timely emptying is impaired
Solution Approach 1:
A compression state sensing unit is implemented to detect the rotational angle of the compressing part, providing feedback information about the dust collection amount. The control unit calculates the dust collection amount based on the rotational angle and displays warning notifications in multiple levels, enabling accurate measurement while maintaining relatively simple system complexity.
4Quantity of substance
If a compressing part is added to compress dust, then dust storage efficiency is improved, but device complexity increases due to additional components
Solution Approach 1:
The compressing part is designed to perform multiple functions: it compresses dust during the dust collection process, serves as a rotor for the compression motor, and its rotational angle is used by the compression state sensing unit to calculate dust collection amount. This multi-functionality reduces the overall device complexity while maintaining improved dust storage efficiency.
