Microwave Energy Treatment for Onychomycosis Pathogen Elimination

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current treatments for infectious diseases of keratinized tissues, such as onychomycosis, are inefficient, with high clinical failure rates, potential organ toxicity, long treatment times, and relapse issues, due to the difficulty in delivering medicaments to water-insoluble keratin tissues.

Innovation Solution

The use of electromagnetic energy, specifically microwave or millimeter wave energy, is applied to keratinized tissues to kill pathogens by inducing 'superheating' and explosion of fungal, bacterial, or parasitic cells, without relying on electrical conduction, allowing for localized and non-invasive treatment with minimal side effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If oral administration of terbinafine or itraconazole is used to treat onychomycosis, then the pathogen can be killed, but the treatment has high clinical failure rate and potential organ toxicity

Engineering Contradiction:

Improveclinical failure rateVSAvoidorgan toxicity

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the chemical pharmacological system (oral antifungal medications) with an electromagnetic energy system. The electromagnetic energy directly penetrates and kills the pathogen through dielectric heating, eliminating the need for systemic medication absorption and thereby avoiding organ toxicity while maintaining treatment effectiveness.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces electromagnetic energy as an intermediary that mediates the treatment between the clinician and the pathogen. This intermediary form of energy can penetrate the keratinized tissue without requiring the pathogen to be accessible to chemical drugs, thus achieving pathogen elimination without the harmful side effects of conventional medications.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If oral antifungal medications are administered, then the pathogen can be treated, but the treatment time is long and costly

Engineering Contradiction:

Improvetreatment effectivenessVSAvoidtreatment time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent employs periodic or pulsed application of electromagnetic energy rather than continuous oral medication. The electromagnetic energy is applied in controlled pulses that directly penetrate and kill pathogens, significantly reducing the treatment duration compared to the several months required for oral antifungal therapy to achieve the same effect.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

By substituting chemical medication with electromagnetic energy, the treatment mechanism changes from slow chemical absorption and action to rapid physical energy penetration and pathogen destruction, thereby dramatically reducing treatment time while maintaining effectiveness.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If topical agents are used to treat onychomycosis, then the treatment is localized, but the benefit is little due to poor delivery into keratinized tissue

Engineering Contradiction:

Improvelocalized treatmentVSAvoidtreatment benefit

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces the chemical delivery mechanism of topical agents with electromagnetic energy penetration. The electromagnetic waves can penetrate through the keratinized tissue structure that blocks chemical drugs, enabling effective localized treatment without the delivery barriers that limit topical medication efficacy.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the fundamental parameter of treatment delivery from chemical molecules to electromagnetic energy. This parameter change allows the treatment to penetrate the keratinized tissue barrier that is impermeable to conventional topical drugs, thereby achieving reliable localized treatment effect.

Inventive Principle:

Principle #35Parameter changes

4Reliability

If chemical or surgical removal of infected nail is performed, then the infection can be removed, but the treatment can lead to nail bed shrinkage and dorsal dislocation

Engineering Contradiction:

Improveinfection removalVSAvoidnail bed shrinkage and dorsal dislocation

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent substitutes mechanical/surgical removal with electromagnetic energy treatment. This substitution eliminates the need for physical trauma to the nail bed, thereby removing the infection through non-invasive pathogen destruction while avoiding the harmful structural changes (nail bed shrinkage and dorsal dislocation) caused by surgical removal.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent converts the potentially harmful effect of aggressive treatment into a beneficial non-invasive process. By using electromagnetic energy, the treatment achieves infection removal without causing the harmful structural damage that would result from chemical or surgical approaches, thus turning a potentially harmful treatment into a beneficial one.

Inventive Principle:

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