Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If complex design and high precision requirements are used for lens assembly and optical fiber holder, then manufacturing precision and reliability are improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The optical fiber holder is divided into a holder body and a separate positioning component. The positioning component can be independently manufactured and then assembled to the holder body, simplifying the manufacturing process while maintaining positioning precision. This segmentation allows complex positioning functions to be achieved through simpler, modular parts.
Solution Approach 2:
A positioning component acts as an intermediary element between the lens assembly and the optical fiber holder. This intermediary component simplifies the connection interface and alignment process, reducing the overall design complexity while ensuring accurate positioning and stable connection.
2Stability of the object's composition
If complex design and high precision requirements are used for lens assembly and optical fiber holder, then assembly stability is improved, but assembly difficulty increases
Solution Approach 1:
The positioning component is pre-assembled to the holder body with precise positioning features already in place. This preliminary action ensures that when the lens assembly is installed, the alignment is already optimized, simplifying the final assembly process while guaranteeing assembly stability and reliability.
3Ease of manufacture
If simplified design is used for lens assembly and optical fiber holder, then manufacturing and assembly ease are improved, but manufacturing precision and assembly accuracy decrease
Solution Approach 1:
The positioning component is designed to automatically align and position the lens assembly relative to the optical fiber holder through its geometric features. This self-aligning mechanism eliminates the need for complex external positioning tools or procedures, achieving high assembly accuracy through the component's own structure while keeping the manufacturing process simple.
