Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaner nozzles face challenges such as increased size and complexity due to the placement of rotation motors, limited ability to suction foreign matter efficiently, and the need for manual water supply for mop cleaning.
Innovation Solution
A nozzle design featuring a suction flow path that minimizes length and maintains efficiency, with driving devices symmetrically positioned on both sides to balance weight and reduce structural complexity, and an integrated water tank for automatic mop water supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If one rotation motor is positioned at the center to rotate a pair of rotating bodies, then the structure is simplified, but the suction path length increases and the suction path structure becomes complicated
Solution Approach 1:
The patent divides the single central rotation motor into two separate rotation motors, with each motor positioned laterally to drive one rotating body independently. This segmentation eliminates the need for complex power transmission gears and allows for a more direct, shorter suction path configuration.
Solution Approach 2:
The patent transitions from a central vertical arrangement to a lateral horizontal arrangement of motors and rotating bodies. By positioning motors and rotating bodies side-by-side rather than one above the other, the suction path can be shortened while maintaining the rotating cleaning function.
2Device complexity
If the suction path is formed in the central portion, then the suction path structure is simplified, but the height of the suction port main body increases
Solution Approach 1:
The patent moves the suction path and rotating bodies from a vertical central arrangement to a lateral horizontal arrangement. This dimensional change allows the suction path to remain simple while reducing the overall height of the suction port main body.
3Device complexity
If the height of the suction port main body is increased, then the suction path can be formed centrally, but the cleanable area is reduced and user convenience deteriorates
Solution Approach 1:
By reconfiguring the system from vertical to horizontal arrangement, the patent reduces the height of the suction port main body, improving ease of operation and expanding cleanable areas under furniture and in narrow spaces.
4Device complexity
If a single rotation motor drives multiple rotating bodies, then device simplicity is achieved, but reliability decreases when the motor fails
Solution Approach 1:
The patent segments the motor system into independent units, with each rotation motor driving one rotating body independently. This segmentation ensures that if one motor fails, the other continues to operate, thereby improving system reliability.
Solution Approach 2:
The patent changes the system configuration from a single motor with multiple outputs to multiple independent motors, fundamentally altering the reliability parameter by eliminating single points of failure.

AI summary
A nozzle for a cleaner comprising: a nozzle housing including a nozzle base and a nozzle cover coupled to an upper side of the nozzle base; a flow path forming portion forming a suction flow path extending in a front-rear direction of the nozzle housing between the nozzle cover and the nozzle base; a water tank detachably mounted on the nozzle cover; and a plurality of rotation plates rotatably disposed below the nozzle base and spaced apart from each other in a lateral direction of the nozzle housing, the plurality of rotation plates being configured to be attached to a mop. The nozzle cover further includes: a bottom wall; and a flow path cover protruding upward from the bottom wall to cover the flow path forming portion. In a state in which the water tank is seated on the bottom wall, the water tank covers an upper surface of the flow path cover.
