Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the wrap angle of the material belt on the turning roller is increased to improve drying efficiency, then the drying efficiency is improved, but the risk of material belt breakage increases due to excessive deformation
Solution Approach 1:
The turning roller is made movable along the guide rail, allowing the wrap angle to be dynamically adjusted according to the solid content of the material belt. This dynamic adjustment capability enables the system to optimize the wrap angle for different material conditions, improving drying efficiency while preventing excessive deformation that could cause breakage.
Solution Approach 2:
The patent changes the wrap angle parameter based on the solid content of the material belt. By adjusting this key parameter, the system adapts to different material conditions, ensuring optimal drying performance while maintaining material belt integrity and preventing breakage.
2Device complexity
If a fixed turning mechanism is used to simplify the device structure, then the device complexity is reduced, but the adaptability to material belts with different solid contents deteriorates
Solution Approach 1:
The turning roller is designed to be movable rather than fixed, allowing adjustment of the wrap angle according to different material conditions. This dynamic structure provides adaptability to various solid contents while maintaining relatively simple device complexity through the use of a guide rail and slider mechanism.
Solution Approach 2:
The adjustable turning mechanism serves multiple functions: it can adapt to material belts with different solid contents, optimize drying efficiency for various materials, and prevent breakage by adjusting the wrap angle. This multi-functionality enhances versatility without significantly increasing device complexity.
