Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If different communication methods are adopted by various manufacturers, then each manufacturer can optimize their own communication modules, but interoperability between different manufacturers' modules deteriorates
Solution Approach 1:
The communication unit is designed to support multiple communication protocols (UART, SPI, I2C) simultaneously, enabling it to work with communication modules from different manufacturers. The controller automatically detects which protocol the connected module uses and configures the communication unit accordingly, allowing a single communication unit to serve multiple functions and maintain interoperability across different manufacturer standards
2Reliability
If custom communication modules are developed for each manufacturer's specific protocol, then communication performance is optimized, but development time and cost increase
Solution Approach 1:
Instead of developing separate communication units for each protocol, a single communication unit is designed to handle multiple protocols (UART, SPI, I2C). The controller includes automatic protocol detection capability that identifies the connected module's protocol type and configures the communication unit accordingly, eliminating the need for multiple custom-developed modules and reducing development time while maintaining optimized communication performance for each protocol
Solution Approach 2:
The communication unit's operational parameters (such as data format, clock speed, signal levels) are dynamically changed based on the detected protocol type. The controller automatically adjusts these parameters when a communication module is connected, allowing the same hardware to operate optimally with different protocols without requiring custom development for each case
