Floor Mop Capillary Wick System for Consistent Water Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning devices face challenges in controlling the amount of water on the floor, leading to inconsistent cleaning performance and potential floor damage, with manual systems being prone to variation in wetness and electric systems being vulnerable to clogging and chemical resistance issues.
Innovation Solution
A semi-closed liquid distribution system where the cleaning cloth acts as a wick, using capillary forces to absorb water from a reservoir, maintaining consistent wetness levels and preventing clogging, with adjustable hole placement and size to optimize water flow and resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual mop and bucket systems are used, then the device complexity is low, but the consistency of water distribution on the floor deteriorates
Solution Approach 1:
The patent replaces manual mechanical wringing operations with a passive capillary wick mechanism. The wick automatically absorbs water from the reservoir and delivers it to the cleaning cloth through capillary action, eliminating the need for manual wringing while ensuring consistent water distribution across the floor surface.
Solution Approach 2:
The wick system operates autonomously without requiring user intervention. The capillary forces within the wick material automatically regulate water flow from the reservoir to the cleaning cloth, maintaining consistent moisture levels independent of cleaning speed or user technique.
2Reliability
If pre-wetted cloths are used, then the water distribution consistency improves, but the cleaning duration deteriorates due to rapid drying
Solution Approach 1:
The reservoir-wick-cloth system establishes a continuous water supply mechanism. As the cleaning cloth becomes damp during use, the wick continuously draws additional water from the reservoir to maintain optimal moisture levels, enabling extended cleaning duration without frequent interruptions for cloth replacement or re-wetting.
3Reliability
If electric pumps or dosing systems are used, then the water distribution consistency improves, but the device complexity increases and vulnerability to clogging worsens
Solution Approach 1:
The patent substitutes electric pumps and dosing systems with a passive capillary wick mechanism. This mechanical-free approach eliminates complexity associated with motors, electronics, and control systems while inherently preventing clogging issues that plague pump-based systems, as the wick's porous structure naturally resists blockage from detergent residues.
4Quantity of substance
If small pores in wick material are used for capillary action, then the water absorption capability improves, but the vulnerability to clogging worsens due to detergent and soap scum
Solution Approach 1:
The patent applies different pore sizes to different regions of the wick system. The water-absorbing portion utilizes smaller capillary pores for efficient water uptake, while the water-delivery portion employs larger pores that resist clogging from detergent residues. This spatial differentiation of pore structures allows the system to simultaneously achieve high water absorption and clogging resistance.

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 system ensures consistent and even distribution of water across the floor, independent of cleaning speed and reservoir water levels, reducing clogging risks and maintaining performance over time, with improved resistance to detergents and soap scum.
