Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security systems are installed with fixed configurations, then system stability and reliability are improved, but adaptability and ease of reconfiguration deteriorate
Solution Approach 1:
The system automatically detects sensor locations and adjusts sensor types based on signal strength measurements without requiring installer intervention. The security panel autonomously performs configuration changes when sensors are moved, enabling the system to reconfigure itself while maintaining stability.
Solution Approach 2:
The system dynamically changes sensor type parameters based on detected location changes. When a sensor's signal strength indicates it has been moved to a different location, the system automatically adjusts the sensor type configuration to match the new environmental context, resolving the contradiction between fixed configuration stability and reconfiguration adaptability.
2Measurement precision
If manual reconfiguration by installers is required, then configuration accuracy is improved, but installation time and operational complexity increase
Solution Approach 1:
The security panel automatically detects when sensors are moved by monitoring signal strength changes and autonomously reconfigures the system accordingly. This eliminates the need for installer intervention, reducing installation and reconfiguration time while maintaining configuration accuracy through automated detection and adjustment mechanisms.
Solution Approach 2:
The system continuously monitors wireless signal strength from sensors and uses this feedback to automatically detect location changes. When signal strength indicates a sensor has been moved, the system triggers automatic reconfiguration, ensuring accurate sensor placement detection and configuration adjustment without manual intervention.
3Adaptability or versatility
If sensors are allowed to be moved to different locations, then system flexibility and adaptability are improved, but false alarms and measurement accuracy may deteriorate
Solution Approach 1:
The system continuously monitors signal strength from each sensor and compares it against expected values for known locations. This feedback mechanism enables the system to detect when a sensor has been moved and automatically adjust the sensor type configuration to match the new location characteristics, preventing false alarms while maintaining measurement precision.
Solution Approach 2:
When the system detects a sensor location change through signal strength analysis, it automatically changes the sensor type parameter to correspond to the new location. This dynamic parameter adjustment ensures that sensor triggers remain accurate and meaningful regardless of sensor relocation, resolving the contradiction between relocation flexibility and trigger accuracy.
