Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fixed high coding rate is used for audio transmission, then sound quality is improved, but transmission smoothness deteriorates due to wireless interference and distance
Solution Approach 1:
The patent implements dynamic coding rate adjustment by continuously monitoring throughput and comparing it with the coding rate to determine transmission quality. The system transitions from a fixed coding rate to a dynamic one that adapts to changing wireless conditions, resolving the contradiction between maintaining high sound quality and ensuring transmission smoothness
Solution Approach 2:
The patent establishes a feedback mechanism where the terminal device feeds back throughput information to the host, and the host adjusts the coding rate based on this feedback and the determined transmission quality. This closed-loop control system enables real-time adaptation to wireless conditions, balancing sound quality and transmission reliability
2Reliability
If a low coding rate is used to ensure smooth transmission, then transmission reliability is improved, but sound quality deteriorates
Solution Approach 1:
The system dynamically adjusts the coding rate based on real-time transmission quality assessment. When conditions improve, the coding rate increases to enhance sound quality; when conditions worsen, it decreases to maintain smooth transmission. This dynamic adaptation resolves the trade-off between the two opposing requirements
Solution Approach 2:
The patent changes the coding rate parameter according to determined transmission quality. By adjusting this key parameter based on throughput monitoring and quality assessment, the system optimizes both transmission reliability and sound quality under different wireless conditions
3Adaptability or versatility
If coding rate is adjusted frequently to match transmission quality, then adaptation to wireless conditions is improved, but system complexity increases
Solution Approach 1:
The system performs self-adjustment by automatically determining transmission quality through throughput comparison and autonomously adjusting the coding rate without requiring complex external control mechanisms. This self-service approach enhances adaptability while minimizing the need for additional complex system components
Solution Approach 2:
The patent simplifies the adaptation process by focusing on changing a single key parameter (coding rate) based on straightforward throughput comparison. This approach achieves good adaptability without introducing excessive system complexity, as the adjustment logic is based on clear quantitative thresholds
