Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a single cooling device is used to cool the storage chamber, then the device complexity is low, but the cooling performance and temperature uniformity are insufficient
Solution Approach 1:
The storage chamber is divided into multiple temperature zones (first temperature zone and second temperature zone), each equipped with its own cooling device. This segmentation allows independent temperature control in different regions, improving overall cooling performance and temperature uniformity without requiring a single complex cooling system to serve the entire chamber.
Solution Approach 2:
Different regions of the storage chamber are assigned different cooling capacities and control strategies based on their specific temperature requirements. The first cooling device serves the first temperature zone while the second cooling device serves the second temperature zone, allowing each region to receive optimized cooling appropriate to its local needs.
2Productivity
If multiple cooling devices operate independently based on their own temperature detection, then each device can control its local area, but the overall cooling efficiency and coordination are reduced
Solution Approach 1:
The control device receives temperature information from both the first temperature detection device and the second temperature detection device, and uses this feedback to coordinate the operation of the first and second cooling devices. This feedback mechanism ensures that the cooling devices work in harmony rather than independently, improving overall cooling efficiency while maintaining appropriate control complexity.
Solution Approach 2:
The control functions of multiple cooling devices are merged into a single centralized control device that coordinates both cooling devices based on temperature information from both zones. This merging of control functions allows for optimized overall cooling efficiency while managing the complexity of coordinating multiple cooling devices through a unified control system.
