Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional mobile communication devices are used for security measures, then basic position tracking is available, but the system cannot effectively respond to dynamic danger zones that vary by time and situation
Solution Approach 1:
The patent implements dynamic detection by continuously monitoring position and time parameters, and automatically adjusting detection operations based on changing environmental conditions. The system transitions from static danger zone definitions to dynamic assessment, where detection is activated or deactivated based on real-time position-time evaluations against stored danger zone data.
Solution Approach 2:
The system pre-stores danger zone information including position coordinates, time periods, and detection parameters before actual security operations. By preparing detection criteria and parameters in advance, the system can quickly respond to entering danger zones without requiring complex real-time decision-making, thus improving both adaptability and ease of operation.
2Reliability
If multiple detection operations are performed simultaneously to ensure comprehensive security monitoring, then detection coverage is improved, but device energy consumption increases
Solution Approach 1:
The patent implements periodic detection by scheduling detection operations based on time parameters associated with danger zones. Instead of continuous monitoring, the system performs detection at specific time intervals or triggered events, reducing energy consumption while maintaining reliable detection coverage during high-risk periods.
Solution Approach 2:
The system performs detection operations selectively based on position and time conditions rather than continuously. By activating detection only when necessary (partial action), the system achieves adequate security coverage without the excessive energy consumption of constant monitoring across all sensors and detection modes.
3Measurement precision
If detection parameters are set to be highly sensitive to detect all potential threats, then detection accuracy improves, but false alarm rate increases
Solution Approach 1:
The patent applies different detection parameters and sensitivity thresholds for different danger zones and situations. Instead of using uniform high sensitivity across all contexts, the system tailors detection criteria to specific locations, time periods, and threat types, improving detection accuracy for genuine threats while reducing false alarms in low-risk contexts.
Solution Approach 2:
The system dynamically adjusts detection parameters such as sensitivity thresholds, detection ranges, and activation criteria based on position, time, and environmental conditions. By changing parameters according to contextual factors, the system maintains high detection accuracy when threats are present while minimizing false alarms during normal conditions.
