Solution Overview

Problem

Conventional data analysis methods require re-execution of the entire analytical process for raw data when parameters change, leading to inefficiencies due to the large volume of data involved.

Innovation Solution

A data analysis apparatus that uses summary information to identify which facilities require recalculation of degradation levels when parameters change, allowing for selective re-execution of the analytical process only on necessary data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If analytical process is re-executed for the entire raw data every time the parameter is changed, then the accuracy of the analysis result is maintained, but the analysis time increases significantly

Engineering Contradiction:
Improveanalysis result accuracyVSAvoidanalysis time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent segments the raw data into multiple groups based on parameter ranges. When a parameter changes, only the groups affected by the change need to be re-executed, rather than re-processing all raw data. This segmentation allows selective re-execution of analytical processes on specific data subsets, reducing overall analysis time while maintaining accuracy for affected segments.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary grouping of raw data by parameter ranges before the actual analytical process. This preliminary organization enables quick identification of which data groups need re-execution when parameters change, avoiding the need to re-process unrelated data and significantly reducing analysis time.

Inventive Principle:
Principle #10Preliminary action

2Loss of time

If summary information is used to extract facilities requiring recalculation, then the analysis time is reduced, but the device complexity increases

Engineering Contradiction:
Improveanalysis timeVSAvoidsystem complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The patent introduces summary information as an intermediary structure that stores pre-computed degradation levels and parameter associations. This intermediary layer enables efficient identification of facilities requiring recalculation without directly complexifying the core analytical engine, as the summary information acts as a buffer between parameter changes and full re-execution requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary computation of summary information that captures essential relationships between facilities, parameters, and degradation levels. This pre-computed summary data structure enables rapid identification of affected facilities when parameters change, reducing the need for complex real-time analysis while maintaining accuracy.

Inventive Principle:
Principle #10Preliminary action

AI summary

A data analysis apparatus (100) includes a group extracting unit (123) and an analysis executing unit (124). When a parameter is changed, by using summary information (121A), the group extracting unit (123) extracts a facility requiring recalculation of a degradation level from respective facilities corresponding to a plurality of degradation levels included in the summary information (121A). The analysis executing unit (124) recalculates a degradation level of the facility extracted by the group extracting unit (123) by using raw data of the extracted facility and the parameter after change.
