Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mop cleaning devices are large, costly to produce, and have complex lifting structures that are inefficient and prone to precision issues, making them unreliable for both cleaning and spin-drying.
Innovation Solution
A mop cleaning device with a dual-cavity bucket system, where a water pump and valve mechanism allow for simultaneous cleaning and spin-drying at the same position, using a movable support to control water flow between cavities, and an impeller pump for efficient water delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a rotary basket is lifted above the bucket body to drive the mop disc to rotate for spin-drying, then rapid spin-drying is achieved, but the lifting structure becomes complicated and assembly efficiency decreases
Solution Approach 1:
The invention extracts the lifting mechanism from the spin-drying system. Instead of lifting the rotary basket, the mop holder is fixed and the mop head itself is rotated by a drive mechanism directly at the cleaning position, eliminating the complex lifting structure while maintaining high-speed spin-drying capability
Solution Approach 2:
The invention introduces a drive mechanism as an intermediary between the power source and the mop head. This mediator directly rotates the mop head at the fixed cleaning position, avoiding the need for lifting and lowering the entire rotary basket assembly
2Ease of operation
If the rotary basket is lowered below the bucket body for cleaning, then the mop can be immersed in water, but the structure occupies more space and production costs increase
Solution Approach 1:
The invention merges the cleaning and spin-drying functions into a single fixed cleaning position. Both functions are performed at the same location by switching the operational mode of the mop head, eliminating the need for separate spatial zones for cleaning and spin-drying
Solution Approach 2:
The fixed cleaning position serves dual purposes: it is used for both water immersion cleaning and high-speed spin-drying. The mop holder and drive mechanism are designed to accommodate both functions at the same location, maximizing space utilization
3Ease of manufacture
If all parts are made of plastic for the lifting mop bucket, then production cost is reduced, but precision is poor and the lifting structure may get stuck
Solution Approach 1:
The invention uses composite material construction, combining plastic components with metal components in the drive mechanism. Critical precision parts requiring high accuracy and durability are made of metal, while non-critical structural parts remain plastic, achieving both cost-effectiveness and precision
4Volume of stationary object
If a dual-cavity system with valve control is used for cleaning and spin-drying at the same position, then structure size is reduced, but the valve mechanism adds complexity
Solution Approach 1:
The system uses the mop holder's own weight and position to automatically control the valve. When the mop holder is in the cleaning position, it automatically opens the water supply valve; when in the spin-drying position, it automatically closes the valve, eliminating the need for complex automated valve control mechanisms
