Solution Overview

Problem

Current cognitive function inspections for elderly drivers are limited to specific moments and do not effectively detect early signs of cognitive decline during daily activities like driving, making it difficult to identify abnormalities related to cognitive function deterioration.

Innovation Solution

An abnormality determination system and base station device that analyze vehicle data, such as driving behaviors and traveling information, to detect early signs of cognitive decline, providing medical institutions with information for timely intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If cognitive function inspections are conducted only at specific facilities using inspection forms and electronic terminals, then the inspection process is simple and easy to operate, but the inspection cannot detect cognitive function abnormalities in daily life situations such as driving

Engineering Contradiction:
Improvedetection accuracy of cognitive function abnormalitiesVSAvoidcomplexity of inspection system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent transitions from traditional facility-based inspection to in-vehicle inspection, adding a new dimension (mobile inspection environment) to detect cognitive function abnormalities during actual driving situations rather than in static clinic settings

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent replaces manual inspection forms and electronic terminal-based assessments with an automated system that collects vehicle operation data, communication data, and biometric data to objectively evaluate cognitive function during driving

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

2Reliability

If cognitive function inspections are conducted at specific facilities, then the inspection can be standardized, but it cannot confirm the cognitive function state in daily life such as when actually driving

Engineering Contradiction:
Improvereliability of cognitive function assessmentVSAvoidadaptability to real-world driving conditions
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The inspection system is designed to function in multiple environments - both traditional facility settings and mobile in-vehicle settings - allowing standardized assessment protocols to be applied across different contexts including actual driving conditions

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system performs preliminary data collection during normal driving activities, gathering vehicle operation data, communication data, and biometric data before formal assessment is needed, enabling early detection of cognitive function deterioration in real-world conditions

Inventive Principle:
Principle #10Preliminary action

3Loss of time

If early detection of cognitive function abnormalities is implemented through daily driving behavior analysis, then detection timing is improved, but data collection and analysis complexity increases

Engineering Contradiction:
Improvetime for detecting cognitive function abnormalitiesVSAvoidcomplexity of data collection and analysis system
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The complex data collection system is divided into separate functional modules: vehicle operation data collection, communication data collection, biometric data collection, and integrated analysis - each module operates independently and contributes to the overall assessment

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a service providing device as an intermediary that receives data from multiple sources (vehicle, user terminal, medical institution), processes the information, and generates assessment results, simplifying the complexity for end users

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An abnormal indication of the user of the vehicle is determined from vehicle data D1 including traveling information D13 of the vehicle, and medical information created based on information related to the determined abnormal indication of the user and an opinion of a medical worker of the medical institution is notified to a user terminal.
