Solution Overview

Problem

Current treatments for tinnitus are ineffective in providing a reliable cure or significant relief, as they often result in mixed outcomes and fail to target the underlying neural mechanisms causing the condition.

Innovation Solution

A non-invasive or minimally invasive electrical stimulation treatment that simultaneously activates multiple auditory and non-auditory neural pathways through transcutaneous or subcutaneous surface stimulation, combined with sound stimulation, to induce a highly synchronous "shock" in specific brain centers, thereby improving or suppressing tinnitus.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional single-modality treatments (sound therapy, drugs, or single pathway electrical stimulation) are used, then the treatment approach is simple, but the treatment effectiveness is insufficient and outcomes are mixed

Engineering Contradiction:

Improvetreatment effectivenessVSAvoidstimulation approach complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple stimulation modalities (sound stimulation, electrical stimulation of auditory pathways, and electrical stimulation of non-auditory pathways) into a single integrated treatment protocol. This multi-modal approach simultaneously activates multiple neural pathways to converge on the inferior colliculus, creating a synergistic effect that enhances tinnitus suppression compared to any single modality used alone.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The treatment system is designed to perform multiple functions through a unified platform: it can deliver sound stimuli, electrical stimulation to auditory pathways, and electrical stimulation to non-auditory pathways, all coordinated through a single control system. This multi-functional design allows the same device to address different aspects of tinnitus pathophysiology simultaneously.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Manufacturing precision

If multiple neural pathways are stimulated simultaneously to target tinnitus mechanisms, then treatment specificity improves, but the complexity of coordinating stimulation increases

Engineering Contradiction:

Improveneural pathway targeting precisionVSAvoidsynchronization control complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary mapping and characterization of the patient's neural pathways and tinnitus features before initiating the coordinated stimulation protocol. This preliminary assessment allows the control system to pre-calculate optimal timing parameters and stimulation sequences, reducing the complexity of real-time coordination while maintaining high precision in targeting specific neural pathways.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The treatment system incorporates feedback mechanisms that monitor neural responses and tinnitus perception during stimulation. This feedback information is used to dynamically adjust timing parameters and stimulation intensity in real-time, simplifying the coordination complexity through adaptive control while maintaining precise targeting of the inferior colliculus and other relevant brain regions.

Inventive Principle:

Principle #23Feedback

3Object-affected harmful factors

If transcutaneous or subcutaneous surface stimulation is used to avoid invasive procedures, then patient safety and comfort improve, but the precision of brain target activation decreases

Engineering Contradiction:

Improveinvasiveness and patient comfortVSAvoidbrain activation precision

Core Design Contradiction:

Object-affected harmful factorsVSMeasurement precision

Solution Approach 1:

The patent uses the inferior colliculus as an intermediary target that receives converging inputs from multiple pathways. By stimulating upstream pathways (auditory and non-auditory) that all converge on this intermediary structure, the system achieves precise functional activation of the inferior colliculus through non-invasive transcutaneous or subcutaneous stimulation, avoiding the need for direct invasive brain stimulation while maintaining activation precision.

Inventive Principle:

Principle #24Intermediary (Mediator)

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 treatment effectively suppresses tinnitus by altering neural activity patterns in the brain, specifically targeting the abnormal firing rates and synchrony associated with tinnitus, without affecting normal auditory processing.

Implementation Method 1

delivering to the patient at least one synchronized stimulation to the brain, wherein the synchronized stimulation comprises stimulation from at least one auditory pathway and stimulation from at least one non-auditory pathway
