Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaners face issues with suction port assemblies that require complex structures due to single motor-driven rotation bodies, water supply complications, inefficient water distribution, and user fatigue from manual water manipulation.
Innovation Solution
A nozzle for a cleaner with independently driven rotation cleaning parts, a separable water tank, and a water supply system that includes water passing holes, injection nozzles, and adjustable water control mechanisms using user input for easy water management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single rotary motor drives a pair of rotation bodies, then the device complexity is reduced, but the reliability deteriorates because all rotation bodies may not rotate if the motor fails
Solution Approach 1:
The patent divides the single motor system into multiple independent motor units. Each rotation body has its own dedicated motor, allowing independent operation. This segmentation ensures that failure of one motor does not affect the operation of other rotation bodies, thereby improving reliability while maintaining manageable device complexity through modular architecture.
2Device complexity
If water is sprayed to the front surface of the cleaner body, then the water supply structure is simplified, but the water does not sufficiently absorb to the mop and may wet other peripheral structures
Solution Approach 1:
The patent applies local quality by directing water supply specifically to the mop contact area rather than spraying to the front surface. The water supply structure is designed to deliver water precisely where the mop makes contact with the floor, ensuring sufficient absorption while avoiding wetting of other peripheral structures. This localized water delivery improves both efficiency and cleanliness.
3Device complexity
If the user pushes a button to activate the water pump, then the water supply control is simplified, but the user experiences hand fatigue from manual manipulation
Solution Approach 1:
The patent replaces the manual button-push mechanical operation with a foot-operated pedal mechanism. This substitution allows the user to control water supply using their foot instead of their hand, eliminating hand fatigue while maintaining simple control structure. The pedal mechanism provides ergonomic operation during cleaning tasks.
