Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a specific input-output pin is used for unidirectional signal transmission, then the circuit design is simple, but the signal transmission capability is limited to unidirectional only
Solution Approach 1:
The input-output pin is designed to serve multiple functions by configuring different circuits based on operation modes. The pin can function as input, output, or analog signal transmission by enabling相应的 voltage conversion circuits or data transmission circuits, making a single pin versatile for different signal transmission needs
2Adaptability or versatility
If voltage conversion circuits are added to enable bidirectional transmission, then the signal transmission versatility is improved, but the device complexity increases
Solution Approach 1:
The circuit configuration is made dynamic through mode-setting mechanisms. Different voltage conversion circuits (first voltage conversion circuit for input mode, second voltage conversion circuit for output mode) are enabled or disabled based on the operation mode, allowing the system to adapt its complexity to the specific transmission requirement rather than always maintaining maximum complexity
