Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If radio relay stations are built on high places to enable communication, then communication coverage is improved, but blind spots remain in areas with high-rise buildings that hinder signals
Solution Approach 1:
The patent introduces a mobile communication network as an intermediary communication channel. When radio relay fails in blind spots, the system automatically switches to mobile network for voice and data transmission, ensuring continuous communication without gaps.
Solution Approach 2:
The system dynamically changes communication parameters by switching between radio relay mode and mobile network mode based on signal availability. This parameter change enables adaptive communication that overcomes the blind spot problem.
2Device complexity
If analog voice signals are transmitted directly through radio relay, then communication simplicity is maintained, but voice information cannot be efficiently processed and extracted
Solution Approach 1:
The patent replaces direct analog voice transmission with a digital processing system. Voice signals are converted to digital format, enabling automated voice recognition and keyword extraction, which significantly improves information processing efficiency while reducing information loss.
Solution Approach 2:
The system performs preliminary voice recognition and keyword extraction before transmitting information to the command center. This preliminary processing ensures that critical information is captured and prepared in advance, improving response time and information utility.
3Loss of time
If radio communication is interrupted in blind spots, then deployment instructions cannot be conveyed timely, but adding more relay stations increases system complexity and cost
Solution Approach 1:
The patent implements a multi-functional communication system that can operate in both radio relay mode and mobile network mode. This universal system eliminates the need for additional relay stations by utilizing existing mobile infrastructure, reducing system complexity while maintaining timely communication.
Solution Approach 2:
The system incorporates feedback mechanisms to monitor communication quality and automatically switch between communication channels. This feedback-driven approach ensures continuous communication without requiring redundant relay stations, optimizing both response time and system complexity.
4Device complexity
If only radio voice terminals are used for communication, then equipment simplicity is maintained, but communication continuity cannot be ensured in areas with signal obstructions
Solution Approach 1:
The patent creates a composite communication system that integrates radio relay technology with mobile network technology. This composite system combines the advantages of both communication methods, ensuring continuous operation in obstructed areas without significantly increasing equipment complexity.
Solution Approach 2:
The system dynamically adapts its communication mode based on environmental conditions. When radio signals are obstructed, the system automatically transitions to mobile network communication, providing dynamic reliability that maintains communication continuity without requiring multiple fixed relay stations.
