Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mounting interfaces with multiple components are used, then reliability of connection is improved, but device complexity and assembly effort increase
Solution Approach 1:
The patent combines multiple mounting functions (positioning, securing, sealing) into a single integrated interface structure. The annular portion with recesses integrates the positioning features that were previously separate components, reducing the number of parts while maintaining connection reliability through the combined positioning and securing mechanism.
Solution Approach 2:
The interface design makes the annular portion serve multiple functions simultaneously: it provides positioning through recesses, securing through engagement features, and structural support. This multi-functional design reduces the need for separate dedicated components for each function, simplifying the overall interface while maintaining reliability.
2Reliability
If conventional mounting interfaces with multiple components are used, then connection security is improved, but assembly effort and time increase
Solution Approach 1:
The recesses in the annular portion are pre-formed to guide the positioning pins into the correct position during assembly. This preliminary positioning action eliminates the need for complex alignment procedures and multiple assembly steps, reducing assembly time while ensuring secure mounting through the pre-designed engagement geometry.
Solution Approach 2:
The interface design allows the mounting process to self-align through the geometric constraints of the recesses and pins. The structure guides itself into the correct position during assembly without requiring external alignment tools or complex procedures, reducing assembly effort while maintaining mounting security.
3Stability of the object's composition
If conventional mounting interfaces are used, then connection stability is improved, but material usage and manufacturing complexity increase
Solution Approach 1:
The interface is segmented into distinct functional features (annular portion, recesses, engagement surfaces) that can be manufactured separately and then assembled or integrated. This segmentation allows each feature to be optimized for its specific function while simplifying the overall manufacturing process compared to creating a single complex monolithic structure.
Solution Approach 2:
The design applies different geometric qualities to different regions of the interface: the annular portion provides structural stability, the recesses provide positioning precision, and the engagement surfaces provide securing strength. This local optimization of geometric properties achieves mounting stability without requiring excessive material throughout the entire structure.
