Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If one rotation motor is used to drive a pair of rotating bodies, then device complexity is reduced, but reliability deteriorates because all rotating bodies cannot operate if the motor fails
Solution Approach 1:
The patent divides the single rotation motor into multiple independent rotation motors, with each motor driving one rotating body independently. This segmentation allows each rotating body to operate autonomously, so if one motor fails, other rotating bodies can continue to function, thereby improving reliability while maintaining reasonable device complexity.
2Ease of operation
If the rotation motor is positioned at the center of the suction port main body, then ease of operation is improved, but device complexity increases due to complicated suction path design
Solution Approach 1:
The patent extracts the rotation motor from the center position of the suction port main body and relocates it to the rear side. This allows the suction path to be designed more simply without needing to accommodate the motor in the center, reducing structural complexity while maintaining ease of operation for the rotating mop.
3Ease of manufacture
If water spray nozzle is disposed at the center of the cleaner main body, then ease of manufacture is improved, but productivity deteriorates because mop cannot sufficiently absorb sprayed water
Solution Approach 1:
The patent changes the spatial arrangement by disposing the water spray nozzle at the rear side of the cleaner main body, aligned with the rotating bodies, rather than at the center. This dimensional repositioning allows water to be sprayed directly onto the rotating bodies and mops, enabling sufficient water absorption and improving cleaning efficiency while maintaining ease of manufacture.
4Ease of operation
If suction path is lengthened to accommodate center-mounted rotation motor, then ease of operation is improved, but loss of energy increases
Solution Approach 1:
The patent extracts the rotation motor from the center position and relocates it to the rear side, which shortens the suction path length. This reduces the energy loss in the suction path while maintaining ease of operation for the rotating mop, as the motor remains functional but is positioned more efficiently.

AI summary
A mop includes a floor cleaning portion, an upper absorbing portion located over the floor cleaning portion, the upper absorbing portion being configured to receive water supplied from a water tank to supply the water to the floor cleaning portion, and an attaching portion located over the floor cleaning portion, the attaching portion being connected to the upper absorbing portion. At least a portion of the attaching portion is located to overlap an outer edge of the upper absorbing portion in a vertical direction.
