Solution Overview

Problem

Existing technologies struggle to accurately identify communication destinations when a second device has a one-to-many relationship with third devices, leading to difficulties in specifying non-transmitted messages.

Innovation Solution

A failure assistance program that classifies communication patterns, generates relevance degree information, and estimates communication destinations using a relevance degree table to narrow down the communication path even in cases of multiple potential targets.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a second device has a one-to-many relationship with third devices, then the system can support multiple communication destinations, but it becomes difficult to accurately specify non-transmitted messages and identify communication destinations

Engineering Contradiction:

Improveone-to-many communication capabilityVSAvoidcommunication destination identification accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent segments the communication analysis by classifying communication patterns into distinct groups. By dividing the communication logs into pattern-based categories, the system can accurately identify which specific communication pattern failed, even when the second device communicates with multiple third devices. This segmentation allows precise identification of non-transmitted messages without being confused by the one-to-many relationship.

Inventive Principle:

Principle #1Segmentation

2Quantity of substance

If communication logs are analyzed without classification, then all communication data is available, but it is difficult to pinpoint specific communication paths among multiple targets

Engineering Contradiction:

Improvecommunication data volumeVSAvoidcommunication path identification difficulty

Core Design Contradiction:

Quantity of substanceVSDifficulty of detecting and measuring

Solution Approach 1:

The patent performs preliminary classification of communication patterns before analyzing failure data. By pre-organizing communication logs into pattern categories based on message types, devices, and communication sequences, the system creates a structured framework that makes subsequent failure analysis straightforward. This preliminary action transforms raw communication data into organized patterns that are easy to query and analyze.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces communication pattern classification as an intermediary layer between raw communication logs and failure analysis. This intermediary structure acts as a mediator that connects the large volume of communication data with the specific failure detection task, making it easier to identify which communication paths failed without being overwhelmed by the total data volume.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Measurement precision

If relevance degree information is generated for each communication pattern, then accurate failure identification is achieved, but additional processing steps and data structures are required

Engineering Contradiction:

Improvefailure identification accuracyVSAvoidprocessing system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system generates relevance degree information automatically through pattern matching and statistical analysis of communication logs. Rather than requiring manual configuration of relevance relationships, the system self-generates this information by analyzing historical communication patterns and determining which patterns are most relevant to each other. This self-service approach reduces the need for manual system configuration while maintaining high accuracy.

Inventive Principle:

Principle #25Self-service

AI summary

A recording medium stores a program that performs failure assistance when a failure occurs in a system in which a first device controls a third device via a second device and causes a computer to execute processing including: classifying a communication pattern to identify communication, by using first information including each communication message from the first device to the second device; generating relevance degree information indicating a relevance degree between first communication between the first and second devices and second communication between the second and third devices, by using second information including a communication log between the first, second and third devices; specifying a first communication pattern that corresponds to a communication message when a failure occurs, when a failure occurs in the second device; and estimating the third device that is a communication destination to be controlled by the first device that is a communication source.
