Solution Overview

Problem

Current methods for cognitive training in memory loss conditions, such as dementia, lack personalized approaches and objective assessments, leading to ineffective memory training programs due to varying degrees and rates of cognitive impairment in patients.

Innovation Solution

A system and device that utilize sensor data from memory exercises to determine cognitive functions used for remembering, advancing exercises based on this data, and calculating an objective cognitive assessment to provide personalized training, incorporating image processing and probabilistic modeling for optimal difficulty adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If tDCS is used to treat memory loss, then cognitive function improvement is achieved, but side effects occur due to after-effects lasting up to an hour

Engineering Contradiction:
Improvecognitive function improvementVSAvoidside effects
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system continuously monitors sensor data during memory exercises to detect cognitive function engagement in real-time. This feedback mechanism allows the system to adjust or pause tDCS stimulation when cognitive functions are not actively engaged, thereby preventing unnecessary side effects while maintaining therapeutic benefits during active training periods.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The training program dynamically adapts its structure and intensity based on real-time sensor data analysis. The system modifies exercise difficulty, duration, and stimulation parameters according to the subject's actual cognitive engagement level, creating a flexible treatment protocol that optimizes therapeutic effect while minimizing harmful after-effects.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If a standardized memory training program is provided, then implementation simplicity is maintained, but personalization needs of individual subjects are not met

Engineering Contradiction:
Improvetraining program implementationVSAvoidpersonalization capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary assessment of each subject's cognitive baseline and impairment profile before initiating the training program. This preliminary action enables the system to pre-configure personalized training parameters and exercise selections, allowing standardized delivery of customized programs without requiring complex real-time adjustments during training sessions.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system automatically adjusts multiple training parameters including exercise difficulty, session duration, stimulation intensity, and exercise selection based on individual subject profiles and real-time performance data. These parameter changes are implemented algorithmically to maintain ease of operation while achieving high levels of personalization for each subject's specific cognitive needs.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If subjective cognitive assessment is used, then assessment simplicity is maintained, but objectivity and accuracy of cognitive function measurement are reduced

Engineering Contradiction:
Improveassessment simplicityVSAvoidcognitive function measurement accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system replaces subjective clinical assessment methods with objective sensor-based measurement technology. Multiple sensors detect physiological signals (such as EEG, eye tracking, or response time data) that objectively indicate cognitive function engagement and performance, eliminating rater subjectivity while maintaining automated, simple assessment procedures through computerized analysis.

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

4Stability of the object's composition

If memory exercises are advanced based on fixed criteria, then training structure is maintained, but adaptation to individual learning rates is prevented

Engineering Contradiction:
Improvetraining structureVSAvoidadaptation to individual rates
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The training program structure dynamically adapts to each subject's learning rate and performance trajectory. The system continuously monitors progress metrics and automatically adjusts exercise advancement timing, difficulty progression, and training intensity to match individual learning curves, maintaining structured delivery while enabling personalized pacing for each subject's cognitive development rate.

Inventive Principle:
Principle #15Dynamics

AI summary

A cognitive training method has a step of obtaining sensor data of a subject during a memory exercise which in turns determining whether the sensor data includes predetermined information indicative of cognitive functions used for remembering. The step of advancing the memory exercise is carried out when it is determined that the sensor data includes predetermined information indicative of cognitive functions used for remembering. The step of calculating an objective cognitive assessment of the subject when the memory exercise is completed and a cognitive training is measured at least partially in response to the advancing the memory exercise. The fact that an objective cognitive assessment is calculated provides a method of using an autodidactic cognitive training device.
