Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication addresses and protocols are implemented in the logic circuitry package, then communication versatility and reliability are improved, but device complexity increases
Solution Approach 1:
The logic circuitry package implements multiple communication addresses (first address for I2C protocol, second address for direct communication) within a single device, allowing it to function across different communication protocols and modes. This multi-functionality enables the same hardware package to adapt to various communication requirements without needing separate dedicated circuits for each protocol.
Solution Approach 2:
The communication functionality is segmented into distinct address spaces and protocol handlers within the logic circuitry. The first logic circuit handles I2C protocol at the first address, while the second logic circuit handles direct communication at the second address. This segmentation allows independent optimization and management of each communication mode, reducing overall system complexity despite supporting multiple protocols.
2Measurement precision
If offset parameters are applied for sensor signal amplification, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system applies offset parameters to modify sensor signal characteristics, transforming raw sensor readings into accurate measurement values. By adjusting these parameters, the logic circuitry compensates for sensor inaccuracies and calibration variations, significantly improving measurement precision without requiring hardware modifications to the sensor itself.
Solution Approach 2:
Offset parameters act as an intermediary between the raw sensor output and the final measurement value. The logic circuitry processes sensor signals through these offset parameters, which serve as calibration mediators that translate physical sensor readings into accurate operational data without requiring direct hardware intervention.
