Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If one rotation motor is used to drive both rotating bodies, then the device complexity is reduced, but the reliability decreases because all rotating bodies cannot operate if the motor fails
Solution Approach 1:
The patent divides the single motor system into multiple independent motor units, with each motor driving one rotating body independently. This segmentation allows individual failure isolation while maintaining overall system functionality.
2Device complexity
If the rotation motor is positioned at the center of the suction port main body, then the structure is simplified, but the suction path length increases and the structure becomes complicated
Solution Approach 1:
The patent extracts the motor from the central position and relocates it to the side of the suction port main body. This extraction eliminates the need for complex central suction path routing and reduces the overall suction path length.
3Device complexity
If the suction path is formed in the central portion of the suction port main body, then the motor positioning is simplified, but the height of the suction port main body increases
Solution Approach 1:
The patent relocates the suction path from the central vertical region to the lateral region of the suction port main body. This dimensional change allows the path to be formed without increasing the height, enabling the device to enter narrow spaces under furniture.
4Adaptability or versatility
If the suction port main body is moved eccentrically, then the cleaning coverage is improved, but the amount of eccentricity increases due to weight distribution
Solution Approach 1:
The patent employs asymmetric weight distribution through strategic component placement, allowing the suction port main body to be intentionally offset from the center of gravity. This asymmetric design enables controlled eccentric movement for better cleaning coverage while maintaining manageable weight balance.
