Solution Overview

Problem

Conventional brain function measurement devices do not accurately determine whether the brain is in a resting state during measurements, leading to reduced reliability and accuracy of brain function analysis.

Innovation Solution

A brain function measurement device that includes a brain blood flow information acquirer, a rest information acquirer, and a controller to acquire and differentiate between resting and non-resting brain states, generating cumulative resting measurement data to improve analysis accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If brain blood flow information is continuously acquired without verifying resting state, then measurement efficiency is improved, but measurement precision deteriorates due to inclusion of non-resting state data

Engineering Contradiction:

Improvemeasurement efficiencyVSAvoidaccuracy of resting brain function analysis

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The system performs preliminary verification of resting state conditions before acquiring brain blood flow information. The rest information acquirer checks whether the subject is in a resting state prior to measurement, ensuring that only data collected during confirmed resting states is included in the analysis, thereby maintaining measurement precision while preserving efficiency through automated screening.

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If resting state verification is performed before each measurement, then measurement precision is improved, but device complexity increases

Engineering Contradiction:

Improveaccuracy of resting brain function analysisVSAvoidcomplexity of measurement system

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The controller integrates multiple functions including rest information acquisition, resting state determination, and brain blood flow information acquisition into a single unified system. This multi-functional integration reduces overall device complexity by consolidating control logic and eliminating the need for separate dedicated components for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If only confirmed resting state data is acquired, then reliability of measurement results is improved, but loss of time occurs due to repeated verification

Engineering Contradiction:

Improvereliability of resting brain function measurementVSAvoidtime for verification process

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system continuously monitors rest information and dynamically adjusts data acquisition based on detected resting states. Rather than performing discrete verification steps that interrupt measurement, the system maintains continuous operation by seamlessly integrating rest state monitoring with brain blood flow information acquisition, ensuring useful action continues without interruption while maintaining reliability.

Inventive Principle:

Principle #20Continuity of useful action
