Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alert information is continuously monitored and acquired from broadcast signals, then the reliability of alert information acquisition is improved, but the response time and processing speed deteriorate due to unnecessary processing when no alerts are present
Solution Approach 1:
The system performs preliminary actions by continuously monitoring alert notification information (such as EAT_Wake_Up flags) in the broadcast signal before actual alert information is transmitted. This allows the device to detect alert conditions early and prepare for rapid acquisition, resolving the contradiction by maintaining reliability through continuous monitoring while reducing response time through pre-detection mechanisms.
Solution Approach 2:
The patent introduces intermediary alert notification information as a mediator between the broadcast signal and the main alert information processing. This intermediary layer (containing flags like EAT_Wake_Up) allows the system to detect alert conditions without immediately processing full alert information, thus maintaining reliability while reducing processing time and resource consumption.
2Speed
If the device continuously processes broadcast signals to detect alert information, then the speed of alert detection is improved, but the energy consumption increases due to continuous operation even in standby states
Solution Approach 1:
The system performs preliminary monitoring of alert notification information during standby states without full processing. By detecting alert conditions through lightweight monitoring of notification flags before activating full alert information processing, the system maintains fast detection speed while significantly reducing energy consumption during non-active periods.
Solution Approach 2:
The system employs periodic monitoring of alert notification information rather than continuous full processing. This allows the device to maintain alert detection capability during standby states by checking for notification flags at intervals, balancing detection speed with energy conservation by activating full processing only when alerts are detected.
3Loss of information
If the demodulation circuit outputs detailed alert notification information, then the completeness of information transmission is improved, but the complexity of the processing circuit increases due to additional terminals and processing requirements
Solution Approach 1:
The system extracts only the essential alert notification information (such as EAT_Wake_Up flags and update state indicators) from the broadcast signal for transmission to the processing circuit, rather than outputting all demodulated information. This maintains information completeness for alert detection while significantly reducing processing circuit complexity by eliminating unnecessary data transmission paths and processing requirements.
Solution Approach 2:
The patent segments the information transmission by separating alert notification information (flags, update states) from full alert information content. This segmentation allows the processing circuit to receive only the necessary notification data for detecting alert conditions, reducing terminal complexity while maintaining complete alert detection capability.
