Solution Overview

Problem

Existing diagnosis systems struggle to efficiently process and display biological information measured in units of heartbeats, leading to overwhelming amounts of data that obscure small changes and make it difficult for doctors to track trends and identify causes of fluctuations in biological information.

Innovation Solution

A diagnosis assistance apparatus and method that divides biological information into segments, generates fluctuating state information, and allows for detailed display of selected segments, enabling efficient tracking of changes and trends through a user-friendly interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If biological information is measured in units of heartbeats to accurately track small changes, then measurement precision is improved, but the quantity of data increases enormously making it difficult to understand overall trends

Engineering Contradiction:
Improveaccuracy of tracking small changesVSAvoidamount of measurement data
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent divides the enormous amount of heartbeat-unit measurement data into multiple segments based on time periods (e.g., daily, weekly, monthly segments). For each segment, it calculates representative values such as average, maximum, minimum, and standard deviation. This segmentation allows doctors to first understand overall trends through aggregated representative values, then drill down into specific segments to examine detailed heartbeat-level data when needed, thus resolving the contradiction between measurement precision and data quantity.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If measurement data is aggregated into representative values to understand overall trends, then ease of operation is improved, but loss of information occurs regarding small changes and fluctuations

Engineering Contradiction:
Improveease of understanding trendsVSAvoidloss of small changes
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent applies local quality by providing different levels of information detail in different contexts. At the segment level, it displays aggregated representative values (average, max, min, standard deviation) for easy overview. When a specific segment is selected or when examining fluctuations, it displays the detailed heartbeat-level measurement data for that segment. This allows doctors to access comprehensive information at the appropriate level of detail, preventing information loss while maintaining ease of operation.

Inventive Principle:
Principle #3Local quality

3Measurement precision

If detailed heartbeat-level data is displayed to examine specific changes, then measurement precision is improved, but device complexity increases making it difficult to operate

Engineering Contradiction:
Improvedetail of biological informationVSAvoidcomplexity of data processing and display
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent implements a dynamic display system that adapts to user needs. The display automatically adjusts between aggregated segment-level views and detailed heartbeat-level views based on user interaction (such as selecting specific segments or time periods). This dynamic switching allows the system to maintain simplicity for overall trend analysis while providing detailed precision when required, without permanently increasing operational complexity.

Inventive Principle:
Principle #15Dynamics

AI summary

A diagnosis assistance apparatus acquires a predetermined period's worth of biological information measured from a living body every heartbeat, from a storage unit storing the biological information, divides the biological information into multiple segments, generates fluctuating state information indicating the fluctuating state of the biological information in each segment, and displays a graph indicating the fluctuating state information of each segment on a display unit. Furthermore, if a certain piece of fluctuating state information is selected in the graph displayed on the display unit, the diagnosis assistance apparatus displays a graph indicating the biological information belonging to the segment corresponding to the selected piece of fluctuating state information on the display unit.
