Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaners face issues with water leakage, inefficient water supply to mops, and complex suction path designs, which hinder effective cleaning and foreign matter removal.
Innovation Solution
A nozzle design featuring a water tank with a drain hole and blocking rib to prevent water leakage, independent driving motors for rotating mops, and a suction flow path that minimizes flow path length and interference with the motor, allowing for efficient water supply and foreign matter suction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single rotation motor is used to drive both rotating bodies, then the device complexity is reduced, but the reliability decreases because if the motor fails, neither rotating body can be rotated
Solution Approach 1:
The single rotation motor is divided into two independent rotation motors, one for each rotating body. This segmentation allows each motor to independently drive its corresponding rotating body, ensuring that if one motor fails, the other can still operate. The patent applies this by providing a first rotation motor for the first rotating body and a second rotation motor for the second rotating body, eliminating the single point of failure in the original design.
2Device complexity
If the rotation motor is positioned at the center of the suction port main body, then the device complexity is reduced, but the suction path becomes longer and more complicated
Solution Approach 1:
The rotation motors are extracted from the central position and relocated to the side portions of the suction port main body. Specifically, the first rotation motor is positioned in the first side portion and the second rotation motor in the second side portion. This extraction eliminates the need for complex central positioning structures and allows for shorter, simpler suction paths that extend laterally from the side portions rather than radially from the center.
3Ease of operation
If the water spray nozzle sprays water forward from the front surface, then the ease of operation is improved, but water may wet nearby structures and the mop cannot sufficiently absorb the water
Solution Approach 1:
The water spray nozzle is repositioned from the front surface to the lower surface of the suction port main body, changing the spraying dimension from forward (horizontal) to downward (vertical). The nozzle sprays water downward onto the rotating bodies and mop, ensuring water is applied directly to the cleaning elements rather than forward where it could wet nearby structures. The rotating bodies then distribute this water across the mop surface through their rotation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The nozzle effectively discharges water, supplies water to mops, and suctions foreign matter, improving cleaning efficiency and floor coverage while preventing water from reaching critical components.
Implementation Method 1
a suction flow path for suctioning air
Implementation Method 2
A drain hole may be formed at the bottom of the nozzle housing to discharge water flowing into the nozzle housing from within the nozzle housing to outside the nozzle housing

AI summary
A nozzle for a cleaner has a nozzle housing, which has a nozzle base and a drain hole for discharging water from the nozzle housing. The nozzle also has a rotary cleaning unit disposed below the nozzle housing. The rotary cleaning unit has a rotation plate that can be attached to a mop. The nozzle has a driving unit that includes a driving motor for driving the rotary cleaning unit. The nozzle also has a control board for controlling the drive motor. In addition, the nozzle has a water tank detachably mounted on an upper side of the nozzle housing. The water tank stores water and supplies the water to the rotary cleaning unit.
