Solution Overview

Problem

Conventional multimedia conference codes, typically nine-digit numbers, face issues of security vulnerabilities, capacity limitations, and complexity due to recycling, leading to user inconvenience and increased implementation complexity.

Innovation Solution

Generate conference codes that match the target user's language, ensuring adaptability and security by using a process that includes determining the target language, generating candidate codes that meet preset conditions, and sending these codes to users, thereby increasing code availability and reducing implementation complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional nine-digit conference codes are used, then the system is simple to implement, but security vulnerabilities and capacity limitations occur

Engineering Contradiction:
Improveconference code securityVSAvoidcode generation system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent changes the parameter of conference code structure from fixed nine-digit numbers to language-matched codes with variable lengths. Different languages have different character sets and code structures, which increases the total available code space and enhances security while maintaining implementation feasibility through localized generation rules for each language

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces a new dimension by matching conference codes to user languages rather than using universal numeric codes. This creates language-specific code spaces that dramatically increase total capacity and security without requiring complex cross-language management systems

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Quantity of substance

If conference codes are recycled to increase availability, then code capacity increases, but implementation complexity and security risks increase

Engineering Contradiction:
Improveconference code availabilityVSAvoidcode recycling management complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent performs preliminary action by generating and allocating conference codes from language-matched code spaces before they are needed. Each language has its own pre-defined code structure and character set, allowing codes to be generated on-demand without recycling or reuse, thereby avoiding the complexity of tracking and managing code lifecycles

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If language-matched conference codes are generated, then user convenience and security improve, but code generation complexity increases

Engineering Contradiction:
Improveuser convenienceVSAvoidcode generation process complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies local quality by creating customized conference code generation rules for each language. Each language has its own character set, code structure, and generation algorithm tailored to its linguistic characteristics. This local customization improves user convenience through language-matched codes while containing complexity within isolated language-specific modules rather than requiring a monolithic complex system

Inventive Principle:
Principle #3Local quality
