Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a heating component is used to heat the electric control box in low temperature environments, then the reliability of the air conditioning device is improved, but the risk of high dry burning temperature damaging components increases
Solution Approach 1:
The heating process is segmented into multiple stages: a first heating stage using the heating component to raise the temperature, followed by a second heating stage using circulating fans for heat circulation. This segmentation allows the system to achieve reliable heating while avoiding the harmful effects of continuous high-temperature heating.
Solution Approach 2:
The heating component operates periodically rather than continuously. The controller alternates between activating the heating component for temperature elevation and activating the circulating fans for heat distribution, creating a periodic action pattern that prevents sustained high temperatures and reduces component damage risk.
2Temperature
If the heating component operates continuously to maintain temperature, then the electric control box remains warm, but the probability of component damage due to over-high temperature increases
Solution Approach 1:
The circulating fans serve as an intermediary mechanism between the heating component and the components inside the electric control box. Instead of allowing direct continuous heating, the fans circulate the heated air, distributing heat more evenly and preventing localized overheating that could damage components.
Solution Approach 2:
The system changes the heating parameter from continuous high-temperature heating to periodic heating combined with air circulation. This parameter change allows maintaining adequate temperature for reliability while avoiding the harmful effects of continuous high temperature operation.
