Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the concave system uses a fixed grid pattern, then the structure is simple and reliable, but it cannot adapt to different grain harvesting demands
Solution Approach 1:
The concave system is divided into multiple modular assemblies, each containing a specific grid pattern configuration. These modular assemblies can be independently removed and replaced, allowing the system to adapt to different grain harvesting demands by selecting appropriate modules without redesigning the entire structure.
Solution Approach 2:
The concave system transitions from a static fixed grid pattern to a dynamic reconfigurable system. The grid patterns can be changed during operation by swapping modular assemblies, enabling the system to adapt its characteristics based on the specific grain being harvested while maintaining structural reliability.
2Adaptability or versatility
If the concave system is designed for easy reconfiguration, then adaptability improves, but the device complexity increases
Solution Approach 1:
The system is segmented into standardized modular assemblies that can be easily attached and detached. Each module contains a complete grid pattern configuration, and the segmentation allows for simple replacement operations without requiring complex adjustment mechanisms or tools.
Solution Approach 2:
The modular assemblies are designed with universal mounting interfaces and standardized connection mechanisms. This universality allows the same base structure to support multiple different grid pattern configurations, reducing the need for custom-designed components for each configuration and thereby limiting the increase in device complexity.
3Loss of time
If modularized assemblies are used for quick modification, then the time to reconfigure is reduced, but the manufacturing complexity increases
Solution Approach 1:
By segmenting the concave system into pre-fabricated modular assemblies, the manufacturing process can be simplified through standardized production of identical connection interfaces and mounting structures. This segmentation allows for efficient manufacturing of individual modules that can be quickly assembled and replaced, reducing modification time while keeping manufacturing complexity manageable through repetition of standardized components.
