Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional knowledge model construction systems fail to provide users with know-how for handling faults, as they do not indicate the causal relationship between fault contents and presented countermeasures or causes, limiting the user's ability to effectively handle unknown faults.

Innovation Solution

An information processing method that determines relevant focus items corresponding to input fault data from multiple levels, using a learning model and keyword matching to present these items on a display device, allowing users to learn how to narrow down countermeasures and causes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a knowledge model construction system is used to analyze case data, then fault analysis capability is improved, but the system cannot provide users with know-how for handling faults

Engineering Contradiction:

Improvefault analysis capabilityVSAvoidknow-how for handling faults

Core Design Contradiction:

Measurement precisionVSLoss of information

Solution Approach 1:

The patent segments the fault analysis process into multiple hierarchical levels (first level, second level, third level) with each level containing specific focus items. This segmentation allows the system to present structured guidance step-by-step, transforming comprehensive fault handling know-how into manageable, sequential information that users can follow and learn from.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent prepares and stores structured focus items and their hierarchical relationships in advance within the knowledge model. When a fault occurs, the system can immediately present the pre-organized guidance steps without requiring users to search or analyze unstructured data, thereby providing both accurate fault analysis and actionable know-how simultaneously.

Inventive Principle:

Principle #10Preliminary action

2Loss of time

If conventional fault analysis systems present countermeasures directly, then fault resolution speed is improved, but users cannot learn handling know-how

Engineering Contradiction:

Improvefault resolution speedVSAvoidhandling know-how

Core Design Contradiction:

Loss of timeVSLoss of information

Solution Approach 1:

Instead of presenting all countermeasures at once, the patent divides them into hierarchical levels with multiple focus items per level. Users progress through levels sequentially, receiving structured guidance that maintains fast resolution while teaching systematic fault handling approaches.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system provides feedback by presenting focus items that guide users through the analysis process step-by-step. Each level's focus items serve as feedback on what aspects to examine next, enabling users to learn the systematic approach while efficiently narrowing down fault causes.

Inventive Principle:

Principle #23Feedback

AI summary

This information processing device is configured to: acquire input fault data indicating fault content; determine, in order from an upper level, a corresponding focus item to which the input fault data corresponds, said item selected from a plurality of focus items which were classified for each of a plurality of levels and which are for narrowing down the countermeasures to or the causes of the fault content; and display, on a display device, the corresponding focus item determined for each of the plurality of levels.
