Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed synchronization parameters are used for information transmission between audio playback devices, then the transmission process is simple and stable, but the flexibility of communication is poor

Engineering Contradiction:

Improveflexibility of information transmissionVSAvoidcomplexity of parameter adjustment mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic adjustment of synchronization parameters by allowing audio playback devices to change synchronization window lengths and synchronization periods based on real-time communication conditions. This transforms the fixed parameter system into a dynamic one that adapts to varying transmission requirements, resolving the contradiction between flexibility and simplicity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes synchronization parameters (window length, period duration) based on detected communication conditions such as retransmission rates and information urgency. By modifying these parameters dynamically, the system achieves flexible adaptation without requiring complete system redesign, balancing adaptability with controlled complexity.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If synchronization parameters are adjusted frequently to improve transmission flexibility, then the adaptability increases, but the system complexity and overhead increase

Engineering Contradiction:

Improveadaptability to transmission conditionsVSAvoidtime for parameter detection and adjustment

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent employs periodic detection of communication conditions (such as retransmission rates) and periodic adjustment of synchronization parameters. This periodic approach allows the system to maintain adaptability while avoiding continuous parameter changes, thus reducing the time overhead and computational burden associated with frequent adjustments.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system uses feedback mechanisms where audio playback devices detect transmission conditions (retransmission rates, information urgency) and use this feedback to adjust synchronization parameters accordingly. This closed-loop feedback enables adaptive optimization without requiring excessive detection frequency, balancing adaptability with time efficiency.

Inventive Principle:

Principle #23Feedback
