Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an antenna cable connection terminal is provided with a detection pin to generate a voltage drop for determining cable connection, then the reliability of connection detection is improved, but the device complexity increases
Solution Approach 1:
The antenna connection terminal is segmented into distinct functional components: a detection pin for connection status detection and a signal receiving pin for broadcast signal reception. This segmentation allows independent functionality of each component, improving detection reliability while maintaining manageable structural complexity through modular design.
2Productivity
If channel scanning is performed only after confirming antenna cable connection, then the productivity of initial setting is improved, but the duration of action increases due to additional detection steps
Solution Approach 1:
The detection pin performs preliminary connection status detection before initiating channel scanning. By checking cable connection in advance, the system prevents wasted scanning operations when no cable is connected, improving overall initial setting efficiency despite the added detection step.
Solution Approach 2:
The system implements feedback control by continuously monitoring the voltage drop at the detection pin and using this information to determine whether to proceed with channel scanning. This feedback mechanism ensures that scanning only occurs when proper cable connection is confirmed, optimizing the initial setting process.
