Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for modulating neural activity in peripheral neural structures lack the ability to control conduction effectively, particularly by activity states, leading to undesired effects such as numbness, discomfort, and interference with autonomic functions.
Innovation Solution
A method and system that utilize a magnetic field to produce reversible conduction blocks in peripheral neural structures during specific activity states, allowing for controlled modulation of neural activity by distinguishing between different activity states and applying blocking stimuli to block or reverse conduction as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic field is applied to block conduction in peripheral neural structure, then neural activity is modulated, but subject experiences numbness and discomfort
Solution Approach 1:
The system dynamically adjusts the magnetic field application based on real-time detection of activity states. The blocking stimulus is applied only when the subject is in a first activity state (e.g., sleep or resting) and reversed when transitioning to a second activity state (e.g., wakefulness or movement), making the neural modulation adaptive and state-dependent to avoid harmful effects during inappropriate times
Solution Approach 2:
The system continuously monitors activity state through sensors and uses this feedback to control the magnetic field application. The signal processing portion analyzes sensor data to determine activity state transitions and automatically adjusts the blocking stimulus accordingly, ensuring neural modulation occurs only when beneficial and avoiding numbness and discomfort during active states
2Reliability
If continuous blocking stimulus is applied to peripheral neural structure, then conduction is blocked, but autonomic functions are interfered with
Solution Approach 1:
Instead of continuous blocking, the system applies periodic blocking stimuli synchronized with activity state transitions. The blocking stimulus is activated during specific periods when the subject is in the first activity state and deactivated during the second activity state, creating a rhythmic on-off pattern that maintains conduction block stability when needed while allowing autonomic functions to operate freely during active states
Solution Approach 2:
The system transitions from static continuous blocking to dynamic state-dependent blocking. The blocking stimulus automatically adjusts its application based on real-time activity state detection, being applied only when the subject is in the first activity state and reversed when in the second activity state, thereby preventing interference with autonomic functions during wakeful or active periods
3Reliability
If blocking stimulus is applied during all activity states, then neural modulation is maximized, but convenience is reduced
Solution Approach 1:
The system implements dynamic, state-dependent neural modulation rather than static continuous blocking. By detecting activity states and automatically adjusting blocking stimulus application accordingly, the system maximizes neural modulation effectiveness during appropriate states (first activity state) while eliminating unnecessary blocking during other states (second activity state), thereby improving convenience and reducing side effects
Solution Approach 2:
The system performs self-regulation by automatically detecting activity states and adjusting blocking stimulus application without external intervention. The signal processing portion continuously monitors sensor data and autonomously determines when to apply or reverse the blocking stimulus, making the neural modulation self-adaptive to the subject's state and eliminating the need for manual control while optimizing both effectiveness and convenience
