Solution Overview

Problem

Video and data conferences in cloud conferencing systems are typically independent and require manual triggering of all access terminals to enter data conferences, lacking synchronous integration.

Innovation Solution

Implementing a conference control method where video and data conferences are created in one-to-one correspondence with shared conference IDs and user IDs, utilizing a conference token mechanism to synchronize terminals between video and data conferences based on control instructions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If video and data conferences are implemented as independent systems, then system simplicity is maintained, but synchronous integration and automatic terminal switching cannot be achieved

Engineering Contradiction:
Improvesynchronous integrationVSAvoidsystem integration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges video conference and data conference systems into a unified conference system with shared conference IDs and user IDs. The server integrates both conference types, allowing terminals to participate in both simultaneously through a single login, eliminating the need for separate system entries and achieving synchronous integration.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The conference system is designed with multi-functionality to handle both video conferencing and data conferencing operations through a single unified platform. The server can manage multiple conference types concurrently, and terminals can switch between different conference modes without requiring separate system instances, thus achieving versatility while maintaining reasonable complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Extent of automation

If manual triggering is used for all access terminals to enter data conferences, then system control is simplified, but automation and user experience are degraded

Engineering Contradiction:
Improveautomatic terminal switchingVSAvoidcontrol mechanism
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The system enables automatic terminal switching through self-service mechanisms. When a terminal joins a video conference, it automatically receives the conference ID and can autonomously enter the corresponding data conference without manual intervention. The system itself manages the synchronization and switching processes, reducing the need for complex external control mechanisms.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The server implements feedback mechanisms by monitoring terminal participation status in video conferences and automatically triggering corresponding data conference entries. The system receives feedback about which terminals are in video conferences and responds by automatically enrolling them in associated data conferences, achieving automation through closed-loop control.

Inventive Principle:
Principle #23Feedback

3Productivity

If separate conference IDs are used for video and data conferences, then system security is maintained, but synchronous access and collaboration efficiency are reduced

Engineering Contradiction:
Improvecollaboration efficiencyVSAvoidconference ID management
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines conference ID management by using shared conference IDs for both video and data conferences. This allows terminals to access both conference types using the same identifier, eliminating the need for separate ID management systems and enabling efficient synchronous access while maintaining security through the unified authentication mechanism.

Inventive Principle:
Principle #5Merging (Combining)
