Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If technicians manually inspect and mark correspondences between signal lines and refrigerant pipelines, then installation accuracy is ensured, but installation time increases significantly
Solution Approach 1:
The patent replaces the manual mechanical inspection and marking process with an automated electronic detection system. The controller automatically sends control signals through signal lines, detects temperature changes in indoor units, and identifies correspondences between signal lines and refrigerant pipelines without requiring manual inspection, thereby reducing installation time while maintaining accuracy
Solution Approach 2:
The system enables self-detection and self-identification of pipeline-signal line correspondences. The controller automatically performs the detection process by sending control signals, monitoring temperature changes, and establishing correspondences without human intervention, allowing the installation system to service itself
2Loss of time
If automated temperature detection is used to identify pipeline correspondences, then installation time is reduced, but system complexity increases
Solution Approach 1:
The system uses feedback from temperature sensors to automatically identify pipeline correspondences. The controller sends control signals, detects temperature changes in indoor units, and uses this feedback information to establish correspondences between signal lines and refrigerant pipelines, automating the detection process while keeping the system relatively simple
Solution Approach 2:
The patent detects correspondences by monitoring temperature parameter changes in indoor units after sending control signals. By using temperature as the detection parameter and comparing temperature differences against preset values, the system achieves automated identification without requiring complex detection mechanisms
