Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If electrothermal devices like Peltier elements are used for cooling, then temperature control capability is provided, but cooling performance is insufficient
Solution Approach 1:
The cooling unit is divided into multiple independent electrothermal devices (first, second, third, and fourth electrothermal devices) arranged in a segmented pattern around the storage chamber. This segmentation allows for distributed cooling across different zones, improving overall cooling performance and efficiency compared to a single centralized cooling element.
Solution Approach 2:
The electrothermal devices are arranged in a two-dimensional pattern (first and second devices on one side, third and fourth devices on another side) rather than a single linear arrangement. This dimensional expansion of the cooling element configuration enhances heat exchange surface area and improves cooling performance throughout the storage chamber.
2Temperature
If air cooling is implemented, then temperature reduction is achieved, but dew condensation occurs
Solution Approach 1:
Different regions of the storage chamber are cooled by different electrothermal devices with potentially different cooling intensities. The multiple cooling zones allow for localized temperature control that prevents excessive cooling in any single area, thereby reducing the likelihood of dew condensation while maintaining overall cooling effectiveness.
Solution Approach 2:
The control unit monitors temperature conditions and adjusts the operation of individual electrothermal devices accordingly. This feedback mechanism prevents over-cooling that would lead to dew condensation by dynamically adjusting cooling output based on actual temperature measurements, ensuring optimal cooling without harmful condensation effects.
3Productivity
If cooling air flow is increased, then cooling performance improves, but pressure loss increases
Solution Approach 1:
The cooling air flow is distributed through multiple electrothermal devices rather than concentrated through a single element. This segmentation of the cooling path reduces resistance and pressure loss while maintaining effective cooling, as the air can flow through multiple parallel thermal exchange zones rather than being forced through one bottleneck.
