Solution Overview

Problem

Current diagnostic methods for migraines are inefficient and lack objectivity, often relying on subjective assessments and invasive procedures, which can lead to ineffective treatments and potential risks for patients.

Innovation Solution

A non-invasive system using a headset with microphones or accelerometers to detect vibrations from the cerebral vasculature, processing these signals to identify patterns indicative of migraines and other neurological conditions, providing an objective and quantitative diagnosis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If subjective assessment methods (questionnaires, patient history) are used for migraine diagnosis, then the diagnostic process is simple and quick, but the diagnosis lacks objectivity and precision

Engineering Contradiction:

Improvediagnosis objectivityVSAvoiddiagnostic process complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces subjective mechanical assessment methods with acoustic sensing technology. Microphones and sensors detect objective acoustic signals from cerebral blood flow, transforming the diagnostic process from subjective patient reporting to objective acoustic measurement of vascular physiology

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces acoustic signals as an intermediary between the patient's physiological state and the diagnostic conclusion. The acoustic signals from cerebral vasculature serve as an objective mediator that translates internal physiological conditions into measurable external signals for analysis

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If invasive procedures are used for diagnosis, then measurement precision may improve, but patient safety and ease of operation deteriorate

Engineering Contradiction:

Improvediagnosis accuracyVSAvoidpatient risk

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent substitutes invasive mechanical procedures with non-invasive acoustic sensing. Instead of inserting sensors or instruments into the body, the system uses microphones to listen to acoustic signals transmitted through the skull from cerebral blood flow, eliminating physical invasion while maintaining diagnostic capability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses acoustic waves as an intermediary that can penetrate the skull to reach cerebral vasculature without physical invasion. The acoustic signals serve as a safe mediator that carries diagnostic information from deep within the brain to external sensors without requiring direct contact or intrusion into sensitive areas

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If traditional diagnostic workflows (multiple visits, repeated assessments) are used, then thorough evaluation is achieved, but time consumption and productivity decrease

Engineering Contradiction:

Improveevaluation thoroughnessVSAvoiddiagnostic time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent performs preliminary acoustic assessment that can objectively identify migraine characteristics and vascular patterns in a single visit. This preliminary acoustic evaluation reduces or eliminates the need for multiple follow-up visits and repeated subjective assessments, saving time while maintaining diagnostic reliability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements immediate acoustic feedback that provides objective diagnostic information during the consultation. The real-time analysis of acoustic signals from cerebral blood flow gives practitioners instant feedback on vascular patterns, eliminating the delay of waiting for patient responses across multiple visits

Inventive Principle:

Principle #23Feedback
