Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the detection system uses simple structural design, then the device complexity is reduced, but the reliability of detecting tampering attempts deteriorates
Solution Approach 1:
The tamper detection function is segmented into multiple independent sensor components (accelerometer, magnetometer, gyroscope) that can be individually evaluated. Each sensor detects specific physical parameters, and their combined assessment provides comprehensive tamper detection capability without requiring a single complex system.
Solution Approach 2:
The control unit performs multiple functions: it processes data from different sensor types, evaluates tamper conditions, determines system operational status, and generates appropriate responses. This multi-functional approach consolidates complexity into a single control unit while maintaining high detection reliability.
2Measurement precision
If the system uses multiple sensor types to detect tampering, then the measurement precision of tamper detection is improved, but the device complexity increases
Solution Approach 1:
Multiple sensor types (accelerometer, magnetometer, gyroscope) are merged into a single integrated tamper detection system evaluated by one control unit. The control unit combines data from all sensors using unified logic, creating a cohesive system that achieves high measurement precision without proportionally increasing overall system complexity.
3Reliability
If the detection system continuously monitors sensor data, then the reliability of detecting tampering attempts is improved, but the use of energy increases
Solution Approach 1:
The control unit evaluates sensor data periodically rather than continuously processing all data streams without interruption. By monitoring for specific tamper conditions and only intensifying monitoring when anomalies are detected, the system maintains high detection reliability while reducing overall energy consumption during normal operation.

AI summary
Disclosed is a method for detecting tampering of a target detection system (1), comprising a control unit is in signal communication with a set of present tamper detection sensors, which are associated with a detection member (2). The method includes setting an overall sensor coordination logic for determining a tamper state of the system based on tamper detection data from a predetermined set of sensors, wherein the set of present sensors is a subset. Then, the control unit controls the operating state of each sensor of the set of present sensors and defines a reduced sensor coordination logic, excluding those sensors of the predetermined set that are missing and/or non-working from the overall logic. Thus the present and working sensors cyclically acquire tamper detection data, and the control unit determines the tamper state of the system by processing the data acquired based on the reduced logic.
