Transmission Management System for Videoconference Terminal State Notification

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current videoconference systems do not effectively notify users about the operational state of counterpart terminals, leading to unsuccessful communications due to undetected issues like microphone or speaker troubles at the counterpart terminal.

Innovation Solution

Implementing a notification system that alerts users at a second terminal about the refrained state of a first terminal, allowing them to determine whether to initiate communication based on the terminal's operational state, using a refrained state icon management table and operation state icon management table to display the status.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system only notifies users about login status, then the notification system is simple, but users cannot determine if communication is actually possible due to hardware troubles

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidterminal state information

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The system implements feedback by continuously monitoring the operational state of transmission terminals (microphone, speaker, camera status) and notifying the requesting user about the actual communication capability of the counterpart terminal, enabling informed communication decisions

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The notification system acts as an intermediary between the transmission terminals, conveying operational state information from the counterpart terminal to the requesting user, allowing indirect assessment of communication feasibility without direct testing

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If users can initiate communication with any logged-in user, then communication initiation is easy, but unsuccessful communications occur due to undetected terminal troubles

Engineering Contradiction:

Improvecommunication initiation easeVSAvoidcommunication success rate

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary assessment of the counterpart terminal's operational state before communication initiation, notifying users of any hardware troubles or restrictions that would prevent successful communication, allowing users to avoid initiating failed communications

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The notification system provides preliminary warning about potential communication failures by indicating terminal troubles (microphone, speaker, camera status) before the user initiates communication, preventing wasted communication attempts

Inventive Principle:

Principle #9Preliminary anti-action

3Reliability

If the system provides detailed operational state information, then communication reliability improves, but the system complexity increases

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidnotification system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system extracts only the critical operational state information (microphone, speaker, camera status) from the terminal and transmits it through the notification system, providing sufficient reliability information without implementing complex monitoring of all terminal functions

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

When a refrained state is detected at a first transmission terminal, a transmission management system sends operation state information of the first transmission terminal, which is determined based on the refrained state of the first transmission terminal, to a second transmission terminal that may initiate communication with the first transmission terminal before the second transmission terminal starts communication with the first transmission terminal.
