Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional signal compression techniques are used, then data can be compressed, but transmission efficiency cannot be maximized in complex communication environments
Solution Approach 1:
The patent applies dynamics by making the coding scheme adaptable to different communication environments. The system dynamically selects between PBC and DIFF coding methods based on environmental conditions, allowing the transmission efficiency to be optimized for varying channel characteristics rather than using a fixed compression technique
Solution Approach 2:
The patent changes the parameter of coding method selection based on communication environment parameters. By monitoring channel conditions and adjusting the coding approach (PBC vs DIFF), the system optimizes transmission efficiency for different environmental scenarios
2Measurement precision
If more data is transmitted to improve audio recovery quality, then audio quality can be enhanced, but transmission efficiency decreases
Solution Approach 1:
The patent changes the parameter representation by transforming audio parameters into pilot reference values and difference values. This parameter transformation enables more efficient encoding that maintains audio recovery quality while reducing the amount of data that needs to be transmitted
Solution Approach 2:
The patent performs preliminary action by pre-calculating pilot reference values that capture essential audio characteristics. These pre-computed references enable more efficient subsequent encoding and decoding operations, improving overall transmission efficiency while maintaining quality
3Productivity
If PBC coding is used for efficient data coding, then data compression is improved, but device complexity increases due to multiple coding schemes
Solution Approach 1:
The patent applies dynamics by implementing adaptive selection between PBC and DIFF coding schemes. Rather than permanently implementing all coding methods, the system dynamically chooses the appropriate scheme based on current conditions, maintaining coding efficiency while managing device complexity through conditional implementation
