Solution Overview

Problem

Existing driving ability measurement devices require a long time to measure multiple cognitive function items related to driving ability, making frequent assessments difficult due to time constraints.

Innovation Solution

A driving ability diagnosis device that uses a screen with central and peripheral regions to display marks and measure reaction times, calculating scores for multiple items based on user inputs and reaction times to first and second marks displayed in these regions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple cognitive function items are measured separately using existing devices, then measurement precision is improved, but measurement time increases significantly

Engineering Contradiction:

Improvemeasurement precisionVSAvoidmeasurement time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent combines multiple separate cognitive function measurements (processing speed, attention, judgment) into a single integrated test task. The driver performs one continuous driving simulation task that simultaneously evaluates all three cognitive functions, rather than administering separate tests for each function. This merging approach reduces total measurement time while maintaining comprehensive assessment coverage.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The driving simulation task serves multiple measurement functions simultaneously. A single test scenario evaluates processing speed through reaction time to obstacles, attention through continuous monitoring requirements, and judgment through decision-making in driving situations. This multi-functional approach allows one test to replace multiple specialized tests.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If comprehensive driving ability assessment is conducted, then diagnostic accuracy is improved, but ease of operation deteriorates due to time consumption

Engineering Contradiction:

Improvediagnostic accuracyVSAvoidease of operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent merges comprehensive diagnostic assessment into a single operational test session. All diagnostic criteria (processing speed, attention, judgment) are evaluated within one continuous driving simulation, making the overall process easier to administer while maintaining comprehensive diagnostic coverage.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A driving ability diagnosis device includes an output unit comprised to display a screen including a central region and a peripheral region, an input unit comprised to receive input from a user, and a controller comprised to cause the output unit to display a first mark or a second mark in the central region or the peripheral region a predetermined number of times for a predetermined period of time, judge whether input is received by the input unit while the first mark or the second mark is displayed, measure a reaction time that is a period of time from when the first mark is displayed to when the input unit receives input, and calculate scores for a plurality of items related to driving ability of the user, based on whether input from the user is received by the input unit and the reaction time.
