Solution Overview

Problem

Existing systems for laundry washing machines in large settings, such as nursing homes, rely on hot water and chemicals, increasing costs and drying times, while traditional disinfection methods are ineffectual against resistant pathogens and generate health-risk byproducts.

Innovation Solution

A system that supplies a water-ozone mixture to laundry washing machines, eliminating the need for hot water and chemicals by using multiple ozone generators to create an oxidation reduction potential (ORP) in the water, enhancing washing efficiency and reducing drying time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If hot water and chemicals are used for laundry washing, then washing effectiveness is improved, but operational costs and drying time increase

Engineering Contradiction:

Improvewashing effectivenessVSAvoiddrying time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies ozone (O3), a strong oxidant, to replace hot water and chemicals in the laundry washing process. The ozone is generated on-site and injected into the washing machine water supply, providing disinfection and washing effectiveness without requiring high temperatures or chemical additives, thereby reducing drying time and operational costs

Inventive Principle:

Principle #38Strong oxidants (Accelerated oxidation)

2Reliability

If traditional disinfection methods are used, then pathogen control is attempted, but resistant pathogens are not eliminated and harmful byproducts are generated

Engineering Contradiction:

Improvepathogen controlVSAvoiddisinfection byproducts

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent uses ozone, a strong oxidant, to eliminate pathogen-resistant strains that traditional disinfection methods cannot control. Ozone oxidizes and destroys pathogen cell walls and genetic material, providing effective disinfection without generating harmful byproducts like trihalomethanes and haloacetic acids that result from traditional chlorine-based disinfection

Inventive Principle:

Principle #38Strong oxidants (Accelerated oxidation)

Solution Approach 2:

The patent converts oxygen (O2), a benign substance, into ozone (O3), a powerful disinfectant, through electrical discharge in the ozone generator. This transformation allows the system to generate effective pathogen control on-site without introducing external chemicals that could create harmful byproducts, and the ozone decomposes back into oxygen after use

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
