Solution Overview

Problem

Current psychiatric disorder screening methods require individuals to visit specific locations, such as hospitals, at designated times, causing inconvenience and limiting accessibility.

Innovation Solution

A method and apparatus for psychiatric disorder screening based on conversation, using a system that outputs stimuli like stories, sounds, or pictures and analyzes responses to determine the presence of disorders by comparing correct answer ratios or voice features with those of normal and disease groups.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If psychiatric disorder screening is performed by experts at particular spaces and times, then measurement precision is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvescreening accuracyVSAvoidconvenience

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The system enables individuals to perform psychiatric disorder screening themselves at home using automated conversation analysis, eliminating the need for expert presence while maintaining diagnostic capability through AI-based voice and conversation analysis

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical system of expert-driven face-to-face testing with an automated digital system that uses voice recognition, conversation analysis, and AI algorithms to perform screening independently

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If psychiatric disorder screening is performed at hospitals, then measurement precision is improved, but loss of time increases

Engineering Contradiction:

Improvescreening accuracyVSAvoidbooking and travel time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system allows individuals to perform screening at their convenience without needing to book appointments or travel to hospitals, eliminating preparatory time loss while maintaining diagnostic accuracy through pre-programmed conversation analysis protocols

Inventive Principle:

Principle #10Preliminary action

3Measurement precision

If traditional expert-based screening is used, then measurement precision is improved, but device complexity increases

Engineering Contradiction:

Improvescreening accuracyVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex human expert systems with automated voice recognition and conversation analysis technology, reducing operational complexity while maintaining or improving screening accuracy through systematic AI-based evaluation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Disclosed are a psychiatric disorder screening method and apparatus based on conversation. The psychiatric disorder screening apparatus outputs stimulation including at least one of a story, a word, a sound, a picture, a motion, a color or a direction, and when receiving a response to the stimulation from a testee, determines the presence or absence of a psychiatric disorder by comparing a correct answer ratio of the response or a voice feature included in the response with correct answer ratios or voice features of a normal group and a disease group.
