Rotating Mop Nozzle Layout for Direct Water Feed and Low Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaner nozzles face issues with water distribution to mops, leading to inefficient cleaning and increased complexity in design due to central motor placement, which affects suction path length and structure, and fail to provide effective water supply to mops for floor cleaning.
Innovation Solution
A cleaner nozzle design with a water tank integrated into the nozzle housing, a motor-driven rotation cleaning unit, and a mop configuration featuring a floor cleaning portion, an upper absorbing portion, and a center opening for improved water absorption and alignment with a rotation plate, allowing for independent rotation of mops and efficient water distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a water spray nozzle is installed on the front surface of the cleaner main body to spray water forward, then water can be supplied to the cleaning area, but the sprayed water may wet other nearby structures instead of the mop and the mop cannot sufficiently absorb the water
Solution Approach 1:
The water spray function is extracted from the cleaner main body and integrated directly into the nozzle assembly. The water tank and spray nozzle are now part of the nozzle unit itself, positioned to spray water directly onto the mop rather than forward onto the floor, eliminating the problem of water misdirection to nearby structures.
2Device complexity
If a single rotation motor is positioned at the center of the suction port main body to drive multiple rotating bodies, then the structure is simplified, but the suction path length is lengthened and the structure for forming a suction path becomes complicated
Solution Approach 1:
The single central motor is divided into multiple independent motors, with each motor positioned at the center of its respective rotating body. This segmentation allows each suction path to be shorter and more direct, as the motor is now located at the optimal position for that specific rotation body rather than being centrally positioned for all bodies.
3Device complexity
If the rotation motor is positioned at the center of the suction port main body to rotate multiple rotating bodies, then one motor can drive multiple mops, but all rotating bodies cannot be rotated if the motor fails or malfunctions
Solution Approach 1:
The single central motor system is segmented into multiple independent motors, each dedicated to a specific rotating body. This ensures that if one motor fails, the other rotating bodies can continue to function independently, significantly improving system reliability and redundancy.
4Device complexity
If the water spray nozzle is disposed at the center of the cleaner main body while the mop is arranged in the lateral direction, then the nozzle structure is simplified, but the mop cannot sufficiently absorb the water sprayed forward
Solution Approach 1:
The water spray function is extracted from the cleaner main body and relocated to the nozzle assembly, where the spray nozzle is positioned to direct water onto the mop rather than forward onto the floor, maximizing water absorption efficiency.
Solution Approach 2:
The water spray direction is changed from horizontal (forward onto the floor) to vertical or downward (onto the mop), utilizing a different spatial dimension to achieve better water delivery to the mop for effective cleaning.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances cleaning efficiency by ensuring adequate water supply to mops, reducing friction between the mop and floor, and allowing for independent rotation of mops, thus improving cleaning performance and reducing nozzle height for easier navigation in tight spaces.
