Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the digital parameter value is transmitted directly over a digital communication loop with baseline precision, then the transmission is simple and compatible with existing protocols, but the measurement precision is insufficient for accurate environmental detector readings
Solution Approach 1:
The digital parameter value is divided into multiple components, each with a precision level that does not exceed the baseline precision of the communication loop. This segmentation allows the high-precision detector reading to be transmitted through the existing digital communication loop without requiring protocol changes, thereby resolving the contradiction between measurement precision and device complexity.
2Adaptability or versatility
If multiple subscribers are connected to the same digital communication loop, then the system can monitor multiple locations, but signal collision and misinterpretation may occur
Solution Approach 1:
By segmenting the digital parameter value into multiple components with controlled precision levels, the system maintains compatibility with existing digital communication loop protocols that support multiple subscribers. This segmentation approach prevents signal collision and misinterpretation while enabling scalable multi-location monitoring.
Solution Approach 2:
Checksum components are incorporated into the transmitted digital parameter components to enable error detection. This feedback mechanism ensures reliable signal transmission across the digital communication loop, preventing misinterpretation by subscribers and maintaining signal integrity even when multiple devices are connected.
3Measurement precision
If the communication protocol uses standardized baseline precision, then compatibility with existing protocols is maintained, but accurate transmission of readings with larger value range is not achieved
Solution Approach 1:
The digital parameter value is segmented into multiple components, each transmitted with precision limited to the baseline precision level of the communication protocol. This segmentation enables accurate transmission of readings with larger value ranges while maintaining compatibility with standardized protocols, as each component can be interpreted correctly by existing protocol-compatible devices.
Solution Approach 2:
Instead of increasing the precision of a single parameter transmission, the system transmits multiple parameter components across different dimensional levels. This approach achieves high measurement precision for readings with larger value ranges while preserving protocol compatibility, as each component fits within the standardized precision constraints of the communication loop.
