Estimation System for Psychiatric Disorders via Sound Signal Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems require medical expertise to estimate pathology based on changes in emotion and organ activity from measured signals, making them inaccessible to non-experts.
Innovation Solution
An estimation system comprising a measurement device, an extraction unit for frequency analysis of sound signals, and an estimation unit that calculates a shift amount from homeostasis to determine psychiatric disorders without expert knowledge, using a determination tree to correlate emotions with fundamental frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If expert knowledge on medicine is required to estimate pathology from measured signals, then estimation accuracy can be maintained, but ease of operation deteriorates
Solution Approach 1:
The patent introduces an estimation device as an intermediary between the measured signal and the pathology estimation result. This device automatically performs the complex analysis that previously required expert knowledge, allowing non-experts to obtain accurate pathology estimates by simply providing the measured signal as input.
Solution Approach 2:
The patent replaces the manual expert analysis process with an automated estimation device that uses algorithms and computational methods. This substitution eliminates the need for human experts to directly interpret measured signals, while maintaining or improving estimation accuracy through consistent automated processing.
2Reliability
If expert knowledge is required for pathology estimation, then reliability of estimation can be ensured, but device complexity increases
Solution Approach 1:
The estimation device serves as a specialized intermediary that encapsulates complex medical knowledge and algorithms internally. While the internal processing is sophisticated, the external interface remains simple, allowing non-experts to use the system reliably without needing to understand the underlying complexity.
Solution Approach 2:
The estimation device is designed as a universal tool that can handle various types of measured signals and provide pathology estimates for different conditions. This multi-functionality consolidates what would otherwise require multiple specialized expert systems into a single accessible platform.

AI summary
Includes an extraction unit that extracts first information on a physiological state of a subject and second information on at least one of an emotion and organ activity of the subject from information on a physiology of the subject; a calculation unit that obtains a degree of similarity between changes over time indicated by the first information and the second information which are extracted and calculates a shift amount from a predetermined state in which a homeostasis in the subject is maintained based on the obtained degree of similarity; and an estimation unit that estimates a pathology of the subject based on the calculated shift amount.
