Solution Overview

Problem

Current methods for sanitizing and refreshing sports gear and clothing are inefficient, often requiring excessive time and resources, failing to effectively kill germs and eliminate odors, especially in hard-to-reach areas, and can damage items or produce unpleasant by-products like VOCs and nitric acid.

Innovation Solution

An ionic oxidation system using a catalyzed corona discharge device to generate ionized ozone, combined with a quick cleaning filter cartridge that neutralizes toxic by-products and leaves a fresh scent, ensuring consistent sanitization and deodorization across all surfaces of items.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If ozone technology is used to eliminate odors and kill germs, then sanitization effectiveness is improved, but toxic by-products (VOCs, nitric acid) are generated

Engineering Contradiction:
Improvesanitization effectivenessVSAvoidtoxic by-products
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful toxic by-products (VOCs, nitric acid) generated during ozone sanitization into beneficial substances. The filter cartridge contains alkaline materials that chemically neutralize these acidic by-products, transforming them into safe salts and water, thereby eliminating toxicity while preserving sanitization effectiveness

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

Solution Approach 2:

The filter cartridge acts as an intermediary between the ozone generation process and the user environment. It intercepts and neutralizes toxic by-products before they can escape into the surrounding air, allowing the system to maintain high sanitization performance without exposing users to harmful substances

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If frequent washing is performed to eliminate germs and odors, then hygiene is improved, but item degradation and resource consumption increase

Engineering Contradiction:
Improvehygiene levelVSAvoiditem degradation
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent replaces the mechanical washing system (water, detergent, agitation) with a chemical oxidation system using ozone. This substitution allows germs and odors to be eliminated through oxidation reactions without subjecting items to the physical stress of washing, thereby maintaining hygiene while preventing mechanical degradation

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

Solution Approach 2:

The patent uses ozone, a strong oxidant, to rapidly kill germs and eliminate odors through oxidation reactions. This accelerated oxidation process achieves thorough sanitization in a short time without requiring repeated washing cycles, reducing both resource consumption and item degradation

Inventive Principle:
Principle #38Strong oxidants (Accelerated oxidation)

3Ease of operation

If chemical sprays and wipes are used to sanitize gear, then ease of operation is improved, but sanitization completeness deteriorates

Engineering Contradiction:
Improvesanitization convenienceVSAvoidsanitization completeness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent uses a gas delivery system (pneumatics) to distribute ozone throughout the enclosure. The ozone gas naturally flows and penetrates all surfaces, including hard-to-reach areas, ensuring complete sanitization coverage while maintaining ease of operation through automatic gas circulation

Inventive Principle:
Principle #29Pneumatics and hydraulics

4Loss of substance

If home laundry processes are used to clean clothing, then resource consumption is reduced, but odor elimination effectiveness deteriorates

Engineering Contradiction:
Improveresource consumptionVSAvoidodor elimination effectiveness
Core Design Contradiction:
Loss of substanceVSReliability

Solution Approach 1:

The patent uses ozone, a strong oxidant, to rapidly break down odor-causing bacteria and organic compounds embedded in fabric fibers. This accelerated oxidation process effectively eliminates persistent odors that conventional home laundry processes cannot remove, while consuming fewer resources than traditional washing

Inventive Principle:
Principle #38Strong oxidants (Accelerated oxidation)

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 provides quick, consistent, and effective germ killing and odor elimination, extending the life of items by reducing the need for frequent washing and maintaining a fresh, clean aroma, thus addressing the inefficiencies of existing methods.

Implementation Method 1

a catalyzed corona discharge device to ionize air inside of the enclosure. The device generates a partially ionized cold plasma region on the element to create a supercharged gas mixture containing ionized ozone

Methodology Applied
Scientific EffectCorona discharge: Corona Discharge

Implementation Method 2

The gaseous mixture is circulated inside by means of a fan and airflow system. The airflow system may have different configurations but allows for all sides of an item to be treated during the process by increasing the total effective surface area coming into contact with the gas. This supercharged airflow kills microorganisms it encounters on the surface of any items, effectively eliminating any odors as well

Methodology Applied
Scientific EffectOxidation: Oxidation
