Solution Overview

Problem

Conventional cleaning systems for hard and soft floors rely on chemical surfactants that leave residues and may have adverse health or environmental effects, while also requiring additional cleaning steps and resources.

Innovation Solution

A mobile surface cleaner equipped with an electrolyzing sparging device that generates electrochemically activated (EA) water, which eliminates the need for chemical surfactants by using electrolysis to produce reactive species that enhance cleaning and sanitizing capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If chemical surfactants are used for cleaning, then cleaning effectiveness is improved, but residue on surfaces and environmental harm increase

Engineering Contradiction:

Improvecleaning effectivenessVSAvoidsurface residue and environmental harm

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The invention extracts and eliminates chemical surfactants from the cleaning system, replacing them with electrochemically activated water that generates cleaning action through electrolysis-produced reactive species rather than chemical additives

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention changes the chemical parameters of water through electrolysis, transforming ordinary water into electrochemically activated water with altered pH, oxidation-reduction potential, and reactive species concentration, thereby achieving cleaning without traditional surfactants

Inventive Principle:

Principle #35Parameter changes

2Productivity

If traditional cleaning liquids are used, then cleaning performance is maintained, but additional cleaning steps and resources are required

Engineering Contradiction:

Improvecleaning performanceVSAvoidcleaning steps and resources

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The invention makes water serve multiple functions simultaneously - as solvent, cleaning agent, and sanitizer - through electrochemical activation, eliminating the need for separate detergent formulations and multiple cleaning steps

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The cleaning system becomes self-sufficient by generating its own cleaning agents through onboard electrolysis of water, eliminating dependence on pre-formulated chemical surfactants and reducing resource requirements

Inventive Principle:

Principle #25Self-service
