Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple temperature sensors are incorporated in the acoustic module to detect local temperature increases on a wide contact surface, then temperature monitoring coverage is improved, but the probe cable becomes large and heavy
Solution Approach 1:
Multiple temperature sensor signal lines are merged into a single sensor line through a switching circuit. The switching circuit selectively connects one of multiple temperature sensors to the single sensor line at different time intervals, allowing comprehensive temperature monitoring across the wide contact surface while transmitting all signals through one cable, thus preventing the probe cable from becoming large and heavy
Solution Approach 2:
The system dynamically switches between multiple temperature sensors connected to a single sensor line. The switching circuit changes the connected temperature sensor based on time intervals or detection needs, enabling flexible and comprehensive temperature monitoring across different regions of the wide contact surface without requiring simultaneous connections for all sensors
