Solution Overview

Problem

Conventional cleaning systems leave unwanted residues on surfaces and pose health and environmental risks due to the use of chemical detergents, and they fail to effectively reduce surface tension and solvency without surfactants.

Innovation Solution

A mobile surface cleaner equipped with a functional generator that electrochemically activates water into anolyte and catholyte liquids, which are combined to create a cleaning solution that mimics surfactant properties without the need for chemical detergents, using an ion exchange membrane and electrodes to produce reactive species and meta-stable ions.

VSEngineering Contradiction Analysis

1Reliability

If chemical detergents are used to clean surfaces, then cleaning effectiveness is improved, but unwanted residue is left on surfaces and health/environmental risks increase

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidunwanted residue and health/environmental risks
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The invention changes the chemical parameters of water through electrochemical activation, transforming it into anolyte and catholyte solutions with different pH levels and reactive species concentrations. This allows the cleaning solution to achieve effective cleaning without traditional chemical detergents, thereby eliminating unwanted residue and health/environmental risks while maintaining cleaning effectiveness

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention replaces the chemical mechanism of traditional detergents (surfactants) with an electrochemical mechanism. By using electrolysis and electrochemical reactions in the functional generator, the system produces cleaning-active solutions through electrical energy conversion rather than chemical detergent formulation, substituting one mechanism for another to achieve the same cleaning function without harmful residues

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

2Reliability

If surfactants are used to reduce surface tension, then cleaning power is enhanced, but chemical detergent usage increases and environmental impact worsens

Engineering Contradiction:
Improvecleaning powerVSAvoidenvironmental impact
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The functional generator changes the surface tension parameters of water through electrochemical activation. The anolyte and catholyte solutions produced have modified surface tension properties due to the presence of reactive species and altered molecular structure, enabling effective cleaning without traditional surfactants and reducing environmental impact

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention introduces reactive species (such as hydrogen peroxide, ozone, and hydroxyl radicals) as intermediaries between the electrochemical activation process and the cleaning action. These reactive species mediate the cleaning process by reducing surface tension and enhancing wetting properties without requiring traditional chemical surfactants, thereby reducing environmental impact while maintaining cleaning power

Inventive Principle:
Principle #24Intermediary (Mediator)
