Solution Overview

Problem

Existing technologies fail to effectively detect the onset of headaches, particularly migraines, before the onset of pain, limiting the ability to take preventive measures.

Innovation Solution

A wearable device that monitors vascular vibrations and physiological parameters, such as heart rate variability and pupil dilation, to detect the early signs of a headache by comparing these parameters against thresholds, triggering alerts for preventive actions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple sensors are continuously activated to detect headache onset, then detection reliability is improved, but power consumption increases

Engineering Contradiction:
Improveheadache detection reliabilityVSAvoiddevice power consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The device performs preliminary monitoring of vascular vibration parameters continuously at low power, and only activates additional physiological sensors (heart rate, temperature, pupil dilation) when abnormal patterns are detected, thereby maintaining high detection reliability while minimizing overall power consumption

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The device implements periodic sampling of vascular vibration parameters and only triggers full sensor activation during suspicious periods when headache onset is suspected, rather than maintaining continuous high-power sensor operation, thus balancing detection reliability with energy efficiency

Inventive Principle:
Principle #19Periodic action

2Loss of time

If detection is performed during the aura phase before pain onset, then preventive action effectiveness is improved, but detection complexity increases

Engineering Contradiction:
Improvetime for preventive actionVSAvoiddetection system complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The device is designed to detect and alert users during the aura phase (before pain onset) by monitoring vascular vibration patterns and physiological parameters, enabling preliminary preventive actions such as taking medication or applying cold compresses before the headache fully develops

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The device monitors a specific set of key parameters (vascular vibration, heart rate, temperature, pupil dilation) with focused attention rather than attempting to measure all possible physiological signals, achieving sufficient detection capability during the aura phase without excessive system complexity

Inventive Principle:
Principle #16Partial or excessive action
