Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single flow channel is used for cooling the tubular member, then the device complexity is low, but the cooling efficiency is insufficient and temperature control time is prolonged
Solution Approach 1:
The single flow channel is divided into multiple flow channels arranged in the circumferential direction. This segmentation allows the cooling medium to reach different radial positions simultaneously, improving cooling efficiency and reducing temperature control time without significantly increasing overall device complexity.
Solution Approach 2:
The flow channels are arranged in the circumferential direction rather than solely in the radial direction. This dimensional arrangement allows multiple cooling paths to operate in parallel, enhancing the cooling surface area and improving temperature control efficiency.
2Temperature
If flow channels are positioned far from the outer peripheral surface, then the heating source can be positioned closer to the resin, but the cooling efficiency of the tubular member decreases
Solution Approach 1:
The flow channels are positioned at specific radial locations closer to the outer peripheral surface where cooling is most needed, while the heating source is positioned to effectively heat the resin. This localized optimization ensures efficient temperature control without requiring complex repositioning of entire components.
3Temperature
If the cooling medium flow path is lengthened to increase cooling area, then the cooling effect improves, but the time to reach predetermined temperature increases
Solution Approach 1:
The cooling path is segmented into multiple parallel flow channels distributed in the circumferential direction. This allows the cooling medium to access different cooling zones simultaneously, effectively increasing the cooling area without lengthening the overall flow path, thus maintaining fast temperature reduction speed.
