Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

IoT devices can be maliciously used as jump servers for virus transmission, causing secondary damage, and communication disruptions are difficult to detect in infrequently checked devices.

Innovation Solution

An information terminal disconnects data communication by deleting APN settings upon anomaly detection and transmits operational status via voice communication, while a processing device sends deletion commands and notifies users of anomalies through voice or voice communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If communication function is stopped to prevent secondary damage, then virus transmission is reduced, but user notification of anomaly becomes difficult

Engineering Contradiction:

Improvesecondary damage from virus transmissionVSAvoiduser notification of anomaly

Core Design Contradiction:

Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The communication function is segmented into two independent channels: data communication (which is disconnected to prevent virus transmission) and voice communication (which remains active for user notification). This allows the system to prevent secondary damage while maintaining notification capability through the voice communication network.

Inventive Principle:

Principle #1Segmentation

2Object-generated harmful factors

If data communication is disconnected by deleting APN setting, then virus spread is prevented, but operational status monitoring is impaired

Engineering Contradiction:

Improvevirus spread through data communicationVSAvoidoperational status monitoring

Core Design Contradiction:

Object-generated harmful factorsVSDifficulty of detecting and measuring

Solution Approach 1:

The voice communication network serves as an intermediary channel that enables operational status monitoring without requiring data communication. The system uses voice messages to transmit operational information, allowing continuous monitoring while preventing virus spread through data network disconnection.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An information terminal according to an aspect of the present disclosure is an information terminal that performs communication over a cellular communication network. The information terminal includes: a communication disconnector that disconnects communication that is performed over a data communication network in the cellular communication network by deleting Access Point Name (APN) settings, when an anomaly of the information terminal is detected; and a communication controller that transmits operational information indicating an operational status of the information terminal over a voice communication network in the cellular communication network, after the communication over the data communication network is disconnected.
