Solution Overview
Problem
Conventional migraine medications often come with negative side effects, and there is limited understanding of the root causes of migraine symptoms, necessitating an alternative approach for alleviating these symptoms effectively.
Innovation Solution
A method and device for applying microcurrent treatment using a microcurrent device with a treatment electrode placed superjacent to trigeminal, occipital, auricular, or cervical nerves, adjusting stimulation voltage based on impedance to maintain constant peak current, providing relief from migraine symptoms through transcutaneous electrical nerve stimulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional migraine medications are used, then migraine symptoms are alleviated, but negative side effects occur
Solution Approach 1:
The patent replaces pharmacological treatment (chemical system) with electrical stimulation (physical system). The microcurrent device applies low-level electrical current through electrodes placed on the skin to stimulate nerves directly, substituting the chemical mechanism of medications with an electrical-physiological mechanism that avoids drug-related side effects while treating migraine symptoms
Solution Approach 2:
The patent introduces electrical current as an intermediary between the external device and the nervous system. Instead of medications chemically interacting with bodily systems, the electrical current serves as a mediator that stimulates nerves (trigeminal, occipital, auricular, or cervical nerves) to trigger endogenous pain relief mechanisms, thereby avoiding direct chemical exposure and associated side effects
2Reliability
If stimulation voltage is increased to maintain constant peak current, then treatment effectiveness is improved, but energy consumption increases
Solution Approach 1:
The patent employs a feedback control system where the microcontroller continuously monitors the actual current through the load and dynamically adjusts the pulse width modulation (PWM) duty cycle to maintain constant peak current. This feedback mechanism ensures that the device adapts to varying impedance conditions (such as different skin-contact pressures or positions) while optimizing energy consumption by applying only the necessary voltage to achieve the target current level
Solution Approach 2:
The patent uses dynamic adjustment of stimulation parameters through PWM control. The duty cycle is continuously modified based on real-time feedback to maintain constant peak current despite changes in load impedance. This dynamic approach allows the system to optimize energy delivery by adjusting voltage and pulse width in real-time rather than using fixed high-voltage stimulation
