Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wide range of sensor sensitivities is accommodated, then manufacturing flexibility is improved, but measurement precision deteriorates
Solution Approach 1:
The transmitter unit dynamically adjusts processing parameters including gain, offset, and filtering characteristics based on the detected sensor sensitivity. This allows the system to accommodate sensors with varying sensitivities while maintaining consistent measurement precision through parameter optimization tailored to each sensor's characteristics.
Solution Approach 2:
The system incorporates feedback mechanisms where the transmitter unit receives sensor signals, analyzes their characteristics, and automatically adjusts processing parameters to optimize performance. This closed-loop approach ensures that measurement precision is maintained across the full range of sensor sensitivities by continuously adapting to the actual sensor performance.
2Measurement precision
If temperature compensation is implemented, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The transmitter unit serves as an intermediary that performs temperature compensation processing between the sensor and the receiver/monitor unit. By implementing compensation algorithms in the transmitter unit rather than requiring additional hardware sensors or complex receiver processing, the system achieves improved measurement precision while minimizing the increase in overall device complexity.
3Measurement precision
If digital anti-aliasing filtering is applied, then measurement precision is improved, but loss of information increases
Solution Approach 1:
The system applies digital anti-aliasing filtering with carefully selected filter characteristics that provide sufficient noise rejection to ensure measurement precision while maintaining bandwidth adequate to preserve essential signal details. The filtering is optimized to remove only the harmful aliasing frequencies while retaining the analytically relevant signal components.
