Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication modes (differential, three-phase, single-phase) are supported, then adaptability is improved, but device complexity increases
Solution Approach 1:
The transmitter is designed with a universal architecture that can operate in multiple communication modes (differential, three-phase, and single-phase modes) through a unified voltage setting mechanism. The same transmitter structure handles all modes by selectively applying different signal combinations to the output terminals, eliminating the need for separate transmitter designs for each mode and thereby reducing overall system complexity.
Solution Approach 2:
The transmitter employs dynamic mode switching capability where the communication mode can be changed during operation based on system requirements. The voltage setting sections dynamically adjust their operation to accommodate different modes, allowing the system to adapt to varying communication needs without physical reconfiguration or mode-specific hardware changes.
2Productivity
If three voltage levels are used for data exchange, then productivity is improved, but device complexity increases
Solution Approach 1:
The data exchange process is segmented into multiple parallel channels, each handling specific voltage level transitions. The transmitter divides the data bus into multiple signal paths (first, second, third output terminals) that can independently manage different voltage levels, allowing three-level signaling to achieve higher data capacity without requiring complex centralized control logic for each voltage transition.
