Wearable Neuromodulation via Sensory Pathways
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional treatments for central nervous system conditions, such as ADHD, autism, and Parkinson's disease, often rely on invasive methods like Deep Brain Stimulation or pharmaceuticals with varying effectiveness and risks, and non-invasive alternatives like transcranial magnetic stimulation have limited long-term benefits and are typically administered only in clinical settings.
Innovation Solution
A wearable neuromodulation device that uses sensory stimuli, such as auditory, visual, or tactile inputs, to modulate specific brainwave frequency bands, allowing for targeted neuromodulation outside clinical settings, with adjustable parameters based on real-time feedback from sensors to optimize treatment efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If invasive treatments like Deep Brain Stimulation are used, then treatment effectiveness is improved, but patient risk and invasiveness increase
Solution Approach 1:
The patent uses sensory pathways (auditory, visual, tactile) as intermediaries to indirectly modulate brain activity. Instead of directly stimulating brain regions with electrodes, the system delivers sensory stimuli that naturally activate specific neural circuits, achieving therapeutic effects without invasive procedures. This mediator approach resolves the contradiction by maintaining treatment effectiveness through indirect neural modulation while eliminating surgical risks and patient discomfort associated with invasive methods.
Solution Approach 2:
The patent replaces the mechanical/electrical direct brain stimulation system with a sensory-based neuromodulation system. Rather than using electrodes to mechanically or electrically stimulate brain tissue, the system uses sensory stimuli (sounds, lights, tactile inputs) that the brain naturally processes, substituting a less invasive mechanism while achieving comparable therapeutic outcomes for conditions like ADHD and autism.
2Object-affected harmful factors
If transcranial magnetic stimulation is used, then non-invasive treatment is achieved, but long-term benefits are limited and clinical setting requirement increases device complexity
Solution Approach 1:
The patent implements a dynamic, adaptive stimulation system that adjusts sensory stimulus parameters (intensity, frequency, timing) in real-time based on patient response and therapeutic goals. This dynamic adaptation allows the treatment to be optimized for each patient and session, enabling long-term therapeutic benefits that static TMS protocols cannot achieve, while maintaining non-invasiveness and allowing use in everyday settings.
Solution Approach 2:
The system employs multiple adjustable parameters including stimulus type (auditory, visual, tactile), frequency, intensity, and timing, which can be customized and modified based on patient needs and treatment progress. This parameter flexibility enables sustained therapeutic effects over time by adapting to changing patient conditions, overcoming the limited long-term benefits of fixed-protocol TMS while keeping the device non-invasive and suitable for various settings.
3Object-affected harmful factors
If sensory stimuli are used to modulate brainwave activity, then non-invasive treatment is achieved, but treatment precision and targeting capability may be reduced
Solution Approach 1:
The patent incorporates feedback mechanisms that monitor patient response to sensory stimuli and adjust stimulation parameters accordingly. By measuring physiological responses and behavioral changes, the system optimizes stimulus delivery to target specific brainwave frequency bands and neural circuits, achieving precise neuromodulation without invasive procedures. This feedback-driven precision resolves the contradiction by maintaining treatment accuracy while using non-invasive sensory pathways.

AI summary
Methods and apparatus for modulation of the central nervous system, and more particularly for modulation of brain oscillatory activity and the brain networks that give rise to it. The methods involve using one or more non-invasive stimuli, either alone or in combination, to increase, decrease, or otherwise modulate neural oscillations in the brain. Also described are methods and devices for detecting sub-optimal or pathological neural oscillatory patterns, developing treatment protocols to modify the neural oscillations in a desired manner, introducing a non-invasive stimulus or stimuli through one or more sensory pathways to treat the conditions, and adjusting the treatment protocol to improve the therapeutic effect of the stimulus or stimuli.
