Solution Overview

Problem

Existing floor cleaning systems using flat mops suffer from the issue of dirty water being reused for recharging the mop pad, leading to contaminated cleaning solutions and requiring significant effort to manage the right amount of water based on the floor type, which can result in inefficient cleaning and spread of dirty fluids.

Innovation Solution

A bucket system with a wringing assembly that includes a movable roller and a fixed blade, allowing the mop head to be inserted and withdrawn to separate dirty fluid from clean fluid, and adjust the amount of fluid in the mop pad based on the floor type, reducing the effort required for cleaning and preventing dirty fluid spread.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the same water is used to both clean and recharge the microfiber pad, then the cleaning process is simplified, but the water becomes dirty after the first use and spreads contamination

Engineering Contradiction:
Improvecleaning process simplicityVSAvoidfluid contamination
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The bucket is divided into two separate compartments: a first compartment for dirty water and a second compartment for clean water. This segmentation allows the cleaning process to use clean water for recharging the microfiber pad while dirty water is collected separately, preventing contamination spread while maintaining operational simplicity.

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If the microfiber pad is pressed against a plate to remove water, then water removal is achieved, but significant effort is required from the user

Engineering Contradiction:
Improvewater removal effectivenessVSAvoiduser effort
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The wringing assembly is designed to automatically wring the microfiber pad as it passes through during the normal cleaning process. The rollers and blades work together to extract water from the pad without requiring the user to manually press or squeeze it, making the system self-servicing and significantly reducing user effort while maintaining effective water removal.

Inventive Principle:
Principle #25Self-service

3Device complexity

If a fixed wringing mechanism is used, then the structure is simple, but the amount of water in the pad cannot be adjusted for different floor types

Engineering Contradiction:
Improvewringing mechanism structureVSAvoidwater amount control
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The wringing assembly incorporates movable rollers that can adjust their position and pressure on the microfiber pad. This dynamic mechanism allows the user to control the amount of water extracted from the pad by adjusting the roller position, enabling adaptation to different floor types (e.g., less water for wood floors, more water for tile floors) while maintaining relatively simple device structure.

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

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 effectively separates dirty and clean fluids, reduces the effort needed for wringing, and allows for precise control of the fluid amount in the mop pad, enhancing cleaning efficiency and preventing the spread of contaminated fluids during the cleaning process.
