Solution Overview

Problem

Existing neurofeedback training methods require complex equipment like fMRI to monitor brain activity, making them less accessible and more challenging to implement.

Innovation Solution

A training apparatus that acquires electroencephalogram (EEG) signals from the left hemisphere of a subject and uses a control unit to display teaching information and result information, allowing for easier neurofeedback training without the need for fMRI.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If functional MRI (fMRI) is used to monitor brain activity during neurofeedback training, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improvebrain activity measurement precisionVSAvoidequipment complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces expensive, complex fMRI equipment with inexpensive EEG headsets that can be easily disposed of or replaced. The EEG system provides sufficient measurement precision for neurofeedback training while dramatically reducing device complexity and cost, making the training accessible in various settings including homes and schools.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent uses EEG signals as a simplified copy or proxy for the more complex fMRI brain activity measurements. Instead of directly imaging brain structures with fMRI, the system captures electrical signals from the scalp that correlate with brain activity, providing an indirect but sufficient representation for neurofeedback purposes.

Inventive Principle:
Principle #26Copying

2Measurement precision

If fMRI equipment is used for neurofeedback training, then measurement precision is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvebrain activity measurement precisionVSAvoidtraining accessibility
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The EEG headsets are inexpensive, portable, and easy to set up compared to fMRI machines. They can be quickly donned and removed by subjects without requiring specialized personnel or complex procedures, dramatically improving ease of operation and training accessibility.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent replaces the complex mechanical and infrastructural system of fMRI (large magnets, shielding rooms, specialized personnel) with a simple electronic sensor system that can be used in ordinary environments, making the training much easier to operate and access.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If alternating teaching information is displayed to affect electroencephalogram signals, then productivity is improved, but device complexity increases

Engineering Contradiction:
Improvetraining efficiencyVSAvoidcontrol system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system displays teaching information in alternating periodic cycles (first teaching information, then second teaching information) to systematically train different aspects of attention control. This periodic structure improves training efficiency by ensuring comprehensive coverage of attentional skills while the control logic remains relatively simple and manageable.

Inventive Principle:
Principle #19Periodic action

AI summary

One or more embodiments of the invention is a training apparatus for neurofeedback training and includes an acquisition unit configured to acquire an electroencephalogram signal at a site in a left hemisphere of a subject and a control unit configured to cause a display device to display first teaching information for affecting an electroencephalogram signal for a predetermined time and to cause the display device to display second teaching information for affecting an electroencephalogram signal for a predetermined time after displaying the first teaching information. The control unit causes the display device to display result information generated based on at least one of an electroencephalogram signal received from the acquisition unit while displaying the first teaching information or an electroencephalogram signal received from the acquisition unit while displaying the second teaching information.
