Solution Overview

Problem

Current steam floor mops are inconvenient and time-consuming due to the need for preheating water and uneven steam distribution, leading to incomplete disinfecting and sterilization, and lack of effective stain removal due to smooth cleaning cloths without patterns.

Innovation Solution

A steam floor mop design featuring a manual water pump, steam generator, and a fan-shaped floor brush with rib stripes and steam distributing grooves, allowing instantaneous steam distribution and effective disinfecting, combined with a cleaning cloth with #-shaped checks for efficient stain removal, eliminating the need for preheating and ensuring uniform steam coverage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If water is heated vaporized to generate steam for cleaning, then high-temperature disinfecting and sterilization effect is achieved, but the process takes long time and is inconvenient

Engineering Contradiction:
Improvesteam temperatureVSAvoidpreheating time
Core Design Contradiction:
TemperatureVSLoss of time

Solution Approach 1:

Water is pre-loaded into the water tank before use, eliminating the need for preheating during operation. The heating element and steam generator are pre-assembled in the handle, ready for immediate steam generation when water is added.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The manual water pump replaces automatic electric pumping systems, allowing instant water delivery to the steam generator through manual operation, reducing wait time while maintaining steam temperature.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of manufacture

If the cleaning surface is made flat, then manufacturing is simple, but steam distribution is uneven and cleaning effectiveness is reduced

Engineering Contradiction:
Improvefloor brush manufacturingVSAvoidsteam distribution uniformity
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The floor brush surface is segmented into multiple regions with different textures (smooth areas and patterned areas) to optimize steam distribution and cleaning effectiveness for different types of stains and floor surfaces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different areas of the cleaning cloth have different surface properties - some areas are smooth for general cleaning, while other areas have patterns or stripes for enhanced steam distribution and stain removal, matching specific cleaning needs to specific locations.

Inventive Principle:
Principle #3Local quality

3Ease of manufacture

If the cleaning cloth is made smooth, then it is easy to manufacture, but stains cannot be cleaned easily

Engineering Contradiction:
Improvecleaning cloth manufacturingVSAvoidstain removal effectiveness
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The cleaning cloth is divided into different zones with varying surface textures - smooth zones for general cleaning and patterned zones with raised designs for tackling stubborn stains, providing both ease of manufacture and effective stain removal.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cleaning cloth incorporates local variations in surface texture and pattern density, with smoother areas for delicate surfaces and more textured areas for heavy-duty stain removal, optimizing both manufacturing simplicity and cleaning performance.

Inventive Principle:
Principle #3Local quality

AI summary

The present invention discloses a steam floor mop, comprising a handle; a central body inside which a manual water pump, a water tank, and a steam generator are housed; and a floor brush connected flexibly to the central body, wherein the manual water pump, the water tank, and the steam generator are connected to the floor brush by means of pipes; said handle is connected directly to the piston rod of the manual water pump and serves to manipulate the operation of the manual water pump; said floor brush is covered by a cleaning cloth. In accordance with the steam floor mop of the present invention, by only pushing the handle of the steam floor mop, the steam can be generated and distributed to the floor brush so that the cleaning work having an effect of high temperature disinfecting and sterilization can be realized. It is not needed to power on the water pump additionally so as to supply water to the steam generator to generate the steam.
