Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users with low information literacy face anxiety and potential erroneous terminal operations when initiating remote support, leading to security concerns and hindered adoption of remote support services due to the need for explicit permission and data transmission during remote operation.

Innovation Solution

A mobile terminal and remote operation system that require registration data transmission only during a telephone call, utilizing a mediation server to authenticate and secure the remote operation, with optional videophone verification to prevent unintended operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If explicit permission and authentication procedures are required for remote operation, then security is improved, but user anxiety and operational complexity increase

Engineering Contradiction:

ImprovesecurityVSAvoiduser anxiety

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a telephone call as an intermediary verification mechanism between the user and support terminal. The user verbally confirms permission to the supporter over the phone, which then triggers the remote operation authorization. This intermediary step provides security verification while being simpler and more reassuring for users with low information literacy compared to complex digital authentication procedures.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If users perform terminal operations for authentication without direct contact with supporter, then remote support can be initiated, but erroneous operations and security risks increase

Engineering Contradiction:

Improveremote support initiationVSAvoidauthentication accuracy

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent replaces the mechanical interaction of direct user-supporter contact with a telephone-based verification system. Instead of requiring users to navigate complex authentication interfaces alone, the system uses voice communication to verify user intent, thereby reducing erroneous operations while maintaining remote support initiation capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If registration data transmission is allowed without telephone call verification, then remote operation setup is simplified, but unauthorized operations become possible

Engineering Contradiction:

Improveregistration simplicityVSAvoidauthorization security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent implements preliminary verification through telephone call before allowing registration data transmission. The system checks whether a telephone call is currently active, and only permits authentication data transmission during an active call. This preliminary action ensures that user intent is verified through voice communication before any authorization data is transmitted, preventing unauthorized operations while maintaining simplicity for legitimate cases.

Inventive Principle:

Principle #10Preliminary action

AI summary

A remote operation system includes a user terminal and a mediation server. The mediation server is configured to execute a registration procedure to start a remote operation of the user terminal from a support terminal. The user terminal includes a telephone function unit, and is configured to allow transmitting, from the user terminal to the mediation server, registration data regarding the remote operation on a condition that the telephone function unit is performing a telephone call.
