Solution Overview
Problem
Current phototherapeutic apparatuses using light-induced gamma brain stimulation are uncomfortable for extended use due to flicker perception at theta frequencies, which can lead to neurological issues, and require repeated treatments for optimal effects.
Innovation Solution
A phototherapeutic apparatus with multiple light sources emitting at different brain stimulation rates, including a beat frequency, to stimulate neural oscillations without perceptible flicker, using heterochromatic flicker or sinusoidal modulation to maintain a constant visual appearance and reduce discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If light sources flicker at theta frequencies to stimulate brain waves, then neural oscillation stimulation is achieved, but perceptible flicker causes discomfort and neurological issues
Solution Approach 1:
The patent divides the light stimulation into multiple frequency components: a primary flicker frequency above 50 Hz that is imperceptible, and a lower beat frequency that produces the desired neural stimulation effect. This segmentation allows the system to achieve therapeutic benefits without perceptible discomfort.
Solution Approach 2:
The patent uses beat frequency as an intermediary mechanism. By combining two light frequencies where one is above the perceptible threshold and the other is modulated to create a beat frequency, the system mediates between the need for effective neural stimulation and the need to avoid perceptible flicker discomfort.
2Device complexity
If single frequency light stimulation is used, then apparatus complexity is reduced, but therapeutic effectiveness for multiple neural oscillations is limited
Solution Approach 1:
The patent makes the light apparatus multi-functional by enabling it to produce multiple effective frequencies through the beat frequency mechanism. A single light source configuration can generate various neural stimulation frequencies by adjusting modulation parameters, eliminating the need for multiple separate light sources for different therapies.
