Solution Overview

Problem

Current treatments for noise-induced and ototoxic hearing loss, caused by reactive oxygen species generated from noise and ototoxic drugs like aminoglycoside antibiotics, lack effective prevention and treatment options.

Innovation Solution

A pharmaceutical composition using oat extract, specifically avenanthramide, which inhibits reactive oxygen species, is developed for prevention and treatment of hearing loss, formulated for oral administration and shown to reduce ROS generation by 20% or more.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If aminoglycoside antibiotics are administered to treat bacterial infections, then antibacterial activity is improved, but ototoxic side effects occur due to ROS generation

Engineering Contradiction:
Improveantibacterial activityVSAvoidototoxic side effects
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

Avenanthramide acts as a protective intermediary substance that mediates between the harmful effect of aminoglycoside antibiotics and the auditory cells. It does not eliminate the antibiotic's antibacterial function but introduces a protective component that scavenges ROS generated by the antibiotic, thereby preventing ototoxicity while maintaining therapeutic efficacy

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention converts the harmful ROS generation mechanism of aminoglycoside antibiotics into a manageable condition by introducing avenanthramide, which specifically targets and neutralizes the ROS. The harmful oxidative stress caused by the antibiotic is transformed into a controlled scenario where antioxidant protection is activated, turning a side effect into a manageable parameter

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

2Object-affected harmful factors

If noise exposure occurs, then hearing loss is caused by ROS generation, but no effective prevention or treatment drugs are available

Engineering Contradiction:
Improvehearing lossVSAvoidavailability of prevention/treatment options
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The invention enables the auditory system to protect itself from noise-induced damage through the administration of avenanthramide. Rather than relying on complex medical interventions or procedures, the solution uses a simple antioxidant compound that allows the body's own cellular mechanisms to resist ROS damage, making the system self-protective against noise-induced hearing loss

Inventive Principle:
Principle #25Self-service

3Reliability

If antioxidants are used to prevent hearing loss, then hearing protection is improved, but no effective antioxidant drugs have been developed specifically for this purpose

Engineering Contradiction:
Improvehearing protectionVSAvoidavailability of antioxidant drugs
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The invention employs avenanthramide, a naturally occurring antioxidant compound that can be administered as a temporary protective agent. Rather than requiring long-term complex drug regimens, the solution uses a readily available, naturally-derived antioxidant that provides effective short-term protection during and after noise exposure or antibiotic administration, making hearing protection accessible and practical

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
