Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electronic device connects to a wireless audio output device using short-range wireless communication, then the audio output function is enabled, but latency increases and audio desynchronization occurs
Solution Approach 1:
The patent implements dynamic connection management where the electronic device actively monitors latency between the audio output device and screen output device, and dynamically switches connections based on real-time latency conditions. This dynamic approach resolves the contradiction by adapting the connection state to current system conditions rather than maintaining a fixed connection.
Solution Approach 2:
The system employs feedback mechanisms by continuously monitoring latency metrics and using this information to control connection states. The electronic device receives latency information from both the audio output device and screen output device, processes this feedback, and makes informed decisions about maintaining or switching connections to optimize audio performance.
2Stability of the object's composition
If the electronic device maintains connection with the wireless audio output device, then audio output is stable, but latency increases when a screen output device is also connected
Solution Approach 1:
The connection state is made dynamic rather than static. The electronic device continuously evaluates latency conditions and adjusts the connection state accordingly - maintaining connection when latency is acceptable, and switching to alternative audio output paths when latency exceeds thresholds, thus balancing stability with performance.
Solution Approach 2:
The system changes the operational parameters of the connection by monitoring latency values and switching between different connection states based on these parameter changes. When latency parameters indicate degradation, the system transitions to a different connection configuration to restore optimal performance.
3Adaptability or versatility
If the electronic device connects to both a screen output device and wireless audio output device simultaneously, then functionality is enhanced, but audio desynchronization occurs due to increased latency
Solution Approach 1:
The system uses feedback from latency monitoring to detect synchronization issues and triggers appropriate actions to restore synchronization. When the screen output device and audio output device are both connected, the system monitors their relative latency and takes corrective action to maintain synchronization precision.
Solution Approach 2:
The connection management becomes dynamic, allowing the system to adapt between different connection configurations (both devices connected, audio only, or screen only) based on real-time synchronization requirements, thus maintaining precision while preserving versatility.
