Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If voice synthesis is performed only at the master terminal, then the system structure is simple, but voice synthesis capability at slave terminals is insufficient

Engineering Contradiction:
Improvevoice synthesis capabilityVSAvoidsystem structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The voice synthesis function is segmented and distributed to both master terminals and slave terminals. Each terminal can independently perform voice synthesis based on received volume information, enabling versatile voice synthesis capability across the system while maintaining relatively simple individual terminal structures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Slave terminals are equipped with universal voice synthesis capability by receiving volume information from the master terminal. This allows any terminal in the system to perform voice synthesis, making the system more adaptable and versatile without significantly increasing the complexity of individual terminals.

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

2Manufacturing precision

If volume information is exchanged between master and slave terminals, then voice synthesis quality is improved, but information exchange complexity increases

Engineering Contradiction:
Improvevoice synthesis qualityVSAvoidinformation exchange mechanism
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The master terminal acts as an intermediary that collects volume information from slave terminals and distributes synthesized voice data back to them. This centralized mediation simplifies the information exchange mechanism while enabling high-quality voice synthesis at all terminals through the structured flow of volume information.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If slave terminals perform voice synthesis independently, then voice communication flexibility is enhanced, but control complexity increases

Engineering Contradiction:
Improvevoice communication flexibilityVSAvoidcontrol mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Slave terminals provide volume information feedback to the master terminal, which then distributes synthesized voice data back to the terminals. This feedback mechanism enables flexible independent voice synthesis at slave terminals while maintaining centralized control through the master terminal's coordination role.

Inventive Principle:
Principle #23Feedback
