Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for neurological conditions such as depression, anxiety, and insomnia often require separate modalities like Transcranial Photobiomodulation (tPBM), Transcranial Direct Current Stimulation (tDCS), and Transcranial Alternating Current Stimulation (tACS), which may not fully address patients with multiple conditions effectively.
Innovation Solution
A device that combines tPBM, tDCS, and tACS with dynamic closed-loop feedback using Electro Encephalogram (EEG) signals, allowing for local and network-based processing to analyze and generate signals, thereby providing a comprehensive treatment approach.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate modalities (tPBM, tDCS, tACS) are used to treat neurological conditions, then each modality can be applied independently, but the treatment effectiveness for patients with multiple conditions is insufficient
Solution Approach 1:
The patent combines multiple separate neural modulation modalities (tPBM, tDCS, tACS) into a single integrated device that can deliver all three treatments simultaneously or sequentially. This merging approach allows the device to address multiple neurological conditions in one treatment session, improving versatility and treatment effectiveness while reducing the complexity of using multiple separate devices
Solution Approach 2:
The integrated device is designed to perform multiple functions by incorporating different neural modulation technologies (photobiomodulation, direct current stimulation, and alternating current stimulation) into a single platform. This multi-functional design enables the device to treat various neurological conditions including depression, anxiety, and insomnia with a universal treatment system
2Adaptability or versatility
If static treatment parameters are used, then the treatment protocol is simple to implement, but the treatment cannot adapt to real-time brain state changes
Solution Approach 1:
The patent implements a closed-loop feedback system that continuously monitors brain activity via EEG signals and uses this information to dynamically adjust treatment parameters in real-time. The system processes EEG data to detect brain states and automatically modifies stimulation intensity, frequency, or duration to optimize treatment effectiveness based on the patient's current neurological condition
Solution Approach 2:
The treatment system transitions from static, pre-programmed parameters to dynamic, adaptive parameters that change in real-time based on feedback. The device continuously adjusts stimulation characteristics according to detected brain states, making the treatment flexible and responsive to the patient's evolving neurological condition throughout the therapy session
3Adaptability or versatility
If multiple treatment modalities are combined, then comprehensive treatment coverage is achieved, but the device complexity and control difficulty increase
Solution Approach 1:
The integrated device incorporates automated control systems that reduce the need for manual configuration and monitoring. The system automatically coordinates the multiple treatment modalities, adjusts parameters based on real-time feedback, and manages the complexity of delivering combined therapies, making the operation easier while maintaining comprehensive treatment coverage
