Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional neurofeedback training is used to increase EEG sub-band control, then subjective state control is achieved, but training time becomes excessively long (dozens of sessions or hundreds of hours)
Solution Approach 1:
The system applies entrainment signals (audio and visual) before and during the neurofeedback training session to pre-condition the brainwaves. This preliminary action accelerates the training process by inducing the desired EEG frequency patterns in advance, reducing the time needed to achieve control from hundreds of hours to significantly fewer sessions.
Solution Approach 2:
The entrainment signals are dynamically adjusted based on real-time EEG feedback. The system continuously monitors the subject's brainwave activity and adapts the frequency and intensity of the entrainment signals to optimize the training process, making the training more efficient and reducing the overall time required.
2Productivity
If entrainment technologies are incorporated into neurofeedback, then training efficiency is enhanced and accelerated, but system complexity increases
Solution Approach 1:
The system combines multiple entrainment modalities (audio binaural beats and visual photic stimulation) into a single integrated neurofeedback device. This merging of functions delivers multi-sensory entrainment simultaneously, enhancing training efficiency while managing system complexity through unified design.
Solution Approach 2:
The neurofeedback system is designed to provide multiple functions: EEG monitoring, audio entrainment generation, visual LED entrainment, and real-time adaptive control. This multi-functionality allows a single device to perform comprehensive brainwave training, improving productivity without requiring separate specialized equipment for each function.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Accelerates brainwave self-regulation by aligning audio and visual cues with individual EEG frequencies, reducing training time to achieve desired brainwave states.
Implementation Method 1
The audio signal is generated based on combining a first signal having a first frequency and a second signal having a second frequency. A difference between the first frequency and the second frequency are substantially equal to a dominant electroencephalogram (EEG) frequency associated with a subject.
Implementation Method 2
causing, via the processor and while outputting the audio representing the third signal, a plurality of light emitting diodes (LEDs) included at a headset to activate and deactivate based on the fourth signal
