Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a force sensor and processing system are implemented to accurately detect mechanical shocks, then measurement precision and reliability are improved, but device complexity increases
Solution Approach 1:
The shock detection algorithm is segmented into distinct processing stages: bias determination, shock intensity calculation, severity assessment, and excessive shock detection. Each stage processes data independently and contributes to the final detection result, allowing for modular implementation and reduced computational complexity at each step.
Solution Approach 2:
The system calculates multiple indicators (bias, shock intensity, severity, average shock severity, absolute value indicator, average absolute value indicator) that go beyond a simple threshold comparison. This partial over-processing ensures comprehensive shock characterization while maintaining computational efficiency through systematic reuse of intermediate results.
2Reliability
If real-time monitoring of container conditions is implemented, then cargo safety is improved, but energy consumption increases
Solution Approach 1:
The system performs shock detection calculations at discrete sampling intervals rather than continuously. The processor determines bias, shock intensity, and severity metrics periodically based on incoming force sensor data, enabling real-time monitoring capability while allowing the system to enter low-power states between measurement cycles.
Solution Approach 2:
The modem control unit autonomously processes force sensor data and determines excessive mechanical shock conditions without requiring external intervention or continuous power supply. The system self-manages the detection algorithm execution and can autonomously communicate detection results, reducing overall system energy requirements.
