Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-time monitoring of speed and vibrations is implemented to detect theft, then theft detection accuracy is improved, but device complexity increases
Solution Approach 1:
The theft detection function is segmented into independent sensor modules (speed sensor, vibration sensor) and a control module. Each sensor independently collects specific physical parameters, and the controller processes these segmented data streams separately before integrating them for comprehensive theft detection, thereby improving detection accuracy without overwhelming device complexity
Solution Approach 2:
The controller serves multiple functions: it manages both speed sensor and vibration sensor data, processes theft detection algorithms, communicates with external systems, and controls the energy harvesting module. This multi-functionality consolidates what would otherwise be separate complex systems into a single integrated unit, improving detection capability while managing overall device complexity
2Reliability
If continuous monitoring of speed and vibrations is performed, then theft detection reliability is improved, but energy consumption increases
Solution Approach 1:
Instead of truly continuous monitoring, the system implements periodic sampling of speed and vibration data at optimized intervals. The controller activates sensors at regular periods to collect necessary data for theft detection, maintaining reliability through sufficient sampling frequency while dramatically reducing energy consumption compared to uninterrupted continuous monitoring
Solution Approach 2:
The energy harvesting module provides self-service by generating electrical energy from the device's own vibrations during transit. This harvested energy is stored and used to power the continuous monitoring operations, making the system energy-self-sufficient and eliminating the need for external power sources or frequent battery replacements while maintaining reliable theft detection
