Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a leakage detection circuit is provided around the electronic device to detect refrigerant leakage in a wider range, then the detection coverage is improved, but the wiring becomes complicated
Solution Approach 1:
A repeater unit is introduced as an intermediary device between the control unit and multiple detection circuits. The repeater receives detection results from multiple sensors and transmits them to the control unit, eliminating the need for complex point-to-point wiring between the control unit and each sensor. This mediator approach maintains wide detection coverage while significantly simplifying the wiring structure.
Solution Approach 2:
The detection system is segmented into multiple independent detection circuits, each with its own sensor and processing capability. Each detection circuit can independently detect refrigerant leakage in its local area, and the results are aggregated by the repeater. This segmentation allows for distributed detection coverage without requiring a complex centralized wiring system.
2Measurement precision
If multiple sensors are deployed to detect refrigerant leakage over a wide area, then the detection precision is improved, but the cable installation and maintenance complexity increases
Solution Approach 1:
The repeater unit serves multiple functions: it collects detection data from multiple sensors, processes the signals, and transmits the aggregated information to the control unit. This multi-functional device reduces the number of separate cable connections needed, as all sensors connect to the repeater rather than requiring individual connections to the control unit, thereby simplifying cable installation and maintenance while maintaining multi-point detection precision.
