Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for migraines, including medications and surgical removal of occipital nerves, often provide inadequate relief and are accompanied by side effects, while existing topical stimulation systems lack control over electrical current delivery, leading to uneven and potentially harmful stimulation.
Innovation Solution
A non-invasive hand-held device that transmits electrical stimulation through the skin to the occipital nerves using a repositionable electrode with a conductive gel and a signal generator, ensuring even current delivery by adjusting pressure and impedance, allowing patients to self-apply the treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If implantable occipital nerve stimulators are used, then migraine relief is achieved, but device complexity and surgical requirements increase
Solution Approach 1:
The patent extracts the stimulation function from complex implantable devices and implements it through simple external electrodes that can be applied topically to the skin over the occipital nerve, eliminating the need for surgical implantation while maintaining therapeutic effectiveness
Solution Approach 2:
The patent introduces conductive gel as an intermediary substance between the external electrode and the skin, enabling effective electrical current delivery without direct skin penetration or surgical implantation, thus simplifying the overall system
2Ease of operation
If existing topical stimulation systems are used, then non-invasive treatment is provided, but control over electrical current delivery is insufficient
Solution Approach 1:
The patent incorporates feedback mechanisms through impedance monitoring that automatically adjust electrical current delivery parameters based on real-time contact conditions, ensuring consistent and controlled stimulation while maintaining ease of non-invasive application
Solution Approach 2:
The patent dynamically changes electrical parameters (voltage, current, pulse duration) based on detected impedance variations to maintain optimal stimulation levels, thereby achieving precise current delivery control without compromising user-friendly application
3Ease of operation
If pressure-dependent electrode contact is used, then simple application is possible, but uneven current delivery occurs
Solution Approach 1:
The patent uses real-time impedance monitoring to detect variations in electrode-skin contact pressure and automatically adjusts current delivery parameters to compensate, ensuring uniform current distribution across the treatment area while maintaining simple electrode application
Solution Approach 2:
The patent dynamically modifies electrical stimulation parameters based on detected contact conditions to achieve uniform current delivery, allowing the electrode to be simply applied without requiring precise pressure control by the user
