Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If DMT modulation is used on both subscriber lines and local data transmission networks, then data transmission rate and quality are improved, but device complexity increases due to requiring multiple modulators and demodulators
Solution Approach 1:
The patent combines the first modulator and second modulator into a single modulator unit, and the first demodulator and second demodulator into a single demodulator unit. This merging allows the device to handle both subscriber line signals and local network DMT signals using shared hardware components, thereby reducing device complexity while maintaining the ability to achieve high data transmission rates through DMT modulation on both interfaces.
2Reliability
If specialized data transmission devices are used to achieve high transmission quality, then data transmission quality is improved, but cost increases
Solution Approach 1:
The patent designs a universal data transmission device that can operate with both subscriber lines and local data transmission networks using DMT modulation. By creating a multi-functional device that handles multiple signal types and network configurations, the invention eliminates the need for separate specialized devices for different network types, thereby reducing overall system cost while maintaining high transmission quality through adaptive modulation and network property determination.
3Reliability
If the device adapts to network changes continuously, then transmission quality is maintained, but device complexity and processing requirements increase
Solution Approach 1:
The patent implements a feedback mechanism where the device determines network properties (such as electrical characteristics of the local data transmission network) and uses this information to adaptively adjust modulation parameters. This feedback loop allows the device to maintain optimal transmission quality by responding to network changes while using efficient algorithms to process network property data, balancing adaptability with manageable device complexity.
