Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transcranial electrical or magnetic stimulation is applied to the brain, then brain neuron activity can be stimulated, but the response performance of the brain cannot be expected or guaranteed due to inability to analyze brain neuron activity changes
Solution Approach 1:
The patent applies feedback by capturing brainwave signals after audio stimulation and analyzing pairwise correlation in the channel signals to identify high-correlation response channels. This feedback loop allows the system to determine which brain areas respond to specific audio frequencies, enabling reliable expectation of brain response performance by adjusting stimulation based on measured neural activity changes.
2Ease of operation
If simple electrical or magnetic signals are used for brain stimulation, then the stimulation process is easy to control externally, but complete theoretical analysis of brain neuron activity changes is not possible
Solution Approach 1:
The patent introduces audio signals as an intermediary between external control and brain stimulation. Instead of directly applying electrical or magnetic signals, the system uses audio frequencies that can be easily controlled externally while capturing brainwave responses to infer neural activity changes. This intermediary approach maintains ease of operation while reducing information loss about brain responses.

AI summary
An audio generation device for brain dynamics audio stimulation includes an audio playing device, a brainwave capturing device, and a computing device. The audio playing device sequentially outputs multiple audio signals to give a subject sound stimulation with various audio frequencies. The brainwave capturing device captures brainwave signals from the subject. The computing device analyzes the pairwise dynamics correlation of the channel signals of the brainwave signal to obtain the correlation of the transfer direction associativity in response to the brain stimulation, synthesizes a test audio according to at least one audio frequency corresponding to a target channel, and makes the test audio as an output audio when the target channel belongs to the high-correlation response channel of the brainwave signal that the subject generates in response to listen to the test audio. An audio generation method for brain dynamics audio stimulation is also provided.
