Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If receivers are preset for measurement with known preparation time, then measurement accuracy is improved, but measurement pauses occur reducing position determination reliability
Solution Approach 1:
The system performs preliminary actions by pre-configuring receivers with measurement parameters including multiple measurement time intervals, frequency measurement ranges, and synchronization data before actual signal measurement begins. This allows receivers to be ready for immediate measurement when signals appear, eliminating preparation pauses during critical detection periods.
Solution Approach 2:
The patent implements continuous measurement action by defining multiple measurement time intervals within a synchronized framework, allowing receivers to continuously monitor for signals without interruption. The system maintains ready state through pre-loaded parameters, ensuring no measurement pauses occur when non-cooperative transmitters emit signals at unknown times.
2Device complexity
If receivers are synchronized with measurement pauses for cooperative transmitters, then device complexity is reduced, but position determination fails for non-cooperative transmitters
Solution Approach 1:
The synchronization system is designed with multi-functionality to handle both cooperative and non-cooperative transmitters. By incorporating multiple measurement time intervals and flexible frequency ranges in the measurement parameters, the same synchronized receiver infrastructure can adapt to different transmitter types without requiring separate specialized systems.
Solution Approach 2:
The system utilizes parameter changes by dynamically adjusting measurement time intervals and frequency measurement ranges based on the type of transmitter being detected. The central control unit can modify these parameters in the synchronized list to optimize detection for either cooperative transmitters with known schedules or non-cooperative transmitters with unknown emission times.
3Reliability
If measurement time intervals are extended to cover unknown signal times, then position determination reliability is improved, but time consumption increases
Solution Approach 1:
The extended measurement period is segmented into multiple discrete measurement time intervals within the synchronized framework. This segmentation allows the system to cover unknown signal emission times effectively while maintaining efficient resource utilization, as receivers can process and evaluate data from each interval separately rather than treating it as one continuous lengthy measurement.
Solution Approach 2:
The system employs periodic action by structuring measurements as repeated intervals with defined start times and durations. This periodic structure allows comprehensive coverage of potential signal emission times while enabling efficient data processing and system resource management through regular, predictable measurement cycles.
