Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile function device uses sensor units to sense operator-specific and position-specific characteristic quantities, then the device can detect emergency situations, but the device may generate false alarms or incorrect data processing
Solution Approach 1:
The plausibility unit continuously monitors sensor data and provides feedback to the computing unit. When sensor values are flagged as implausible, the plausibility unit sends signals to the computing unit to adjust or reject those measurements, creating a closed-loop verification system that reduces false alarms while maintaining detection accuracy
Solution Approach 2:
The plausibility unit acts as an intermediary component between the sensor units and the computing unit. It receives raw sensor data, performs plausibility checks, and only passes verified data to the computing unit for emergency situation determination, thereby filtering out false information before it affects the final decision
2Productivity
If the device processes sensor data to determine emergency situations, then emergency response can be triggered, but incorrect data processing may lead to unsafe operations
Solution Approach 1:
The plausibility unit performs preliminary verification of sensor data before the computing unit processes it for emergency situation determination. By checking plausibility in advance, the system ensures that only reliable data enters the emergency response decision-making process, preventing incorrect data from triggering unsafe operations while maintaining rapid response capability
3Measurement precision
If multiple sensor units are used to sense characteristic quantities, then detection capability is improved, but device complexity increases
Solution Approach 1:
The plausibility unit is designed as a universal verification component that can handle data from multiple different sensor units (temperature sensors, acceleration sensors, GPS receivers, etc.). It provides a common plausibility checking mechanism that works across all sensor types, improving measurement precision while avoiding the need for separate verification logic for each sensor
