Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Bluetooth multi-point connection is maintained with multiple external devices, then device connectivity and versatility are improved, but available bandwidth for audio transmission decreases
Solution Approach 1:
The system dynamically adjusts the bitrate of audio data based on real-time bandwidth availability. When bandwidth is sufficient, higher bitrates are used for quality audio transmission. When bandwidth becomes constrained due to multiple connections, the system automatically lowers the bitrate to maintain stable transmission, ensuring continuous operation across all connected devices.
Solution Approach 2:
The patent changes the transmission parameter (bitrate) adaptively. The processor determines the appropriate bitrate by considering the number of active connections and available bandwidth, then adjusts encoding parameters accordingly. This allows the system to optimize between audio quality and connection stability based on current system state.
2Manufacturing precision
If bitrate is increased for higher audio quality, then audio transmission quality is improved, but bandwidth consumption increases
Solution Approach 1:
The system employs dynamic bitrate adjustment where the transmission bitrate is not fixed but varies based on available bandwidth. The processor continuously monitors bandwidth conditions and adjusts the encoding bitrate accordingly, allowing high quality transmission when bandwidth permits and automatic quality reduction when bandwidth is constrained.
Solution Approach 2:
The encoding parameters including bitrate are changed dynamically based on system conditions. The processor determines optimal encoding parameters by analyzing the relationship between desired audio quality and available bandwidth resources, adjusting the bitrate parameter to match current system capabilities.
3Adaptability or versatility
If multiple external devices are connected simultaneously, then system versatility is improved, but connection management complexity increases
Solution Approach 1:
The patent merges the management of multiple Bluetooth connections into a unified handling mechanism. The processor uses a single determination logic to manage all active connections, assessing overall bandwidth availability and connection count rather than managing each connection independently, thereby reducing management complexity while supporting multiple devices.
Solution Approach 2:
The system implements a universal connection management approach where the same processing logic handles all external devices regardless of their specific types or individual requirements. This multi-functional management strategy simplifies the system by applying consistent rules across all connections rather than device-specific handling.
