Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual assembly is used to install multi-fiber connectors, then assembly precision and fiber protection are improved, but assembly time and labor cost increase
Solution Approach 1:
The holder pre-establishes the positioning structure for multi-fiber connectors before assembly. The holder includes positioning holes and guiding structures that pre-determine the exact position and orientation of connectors, eliminating the need for manual measurement and adjustment during assembly.
Solution Approach 2:
The holder acts as an intermediary component between the substrate and the multi-fiber connectors. It provides a standardized interface with positioning holes and mounting structures that facilitate both precise positioning and efficient automated assembly operations.
2Productivity
If automatic assembly is used to install multi-fiber connectors, then assembly efficiency is improved, but fiber damage risk increases
Solution Approach 1:
The holder provides protective structures before assembly occurs. It includes protective coverings and cushioning elements that protect optical fibers from damage during automated handling and assembly operations, preventing fiber breakage and contamination.
Solution Approach 2:
The holder serves as a protective intermediary between automated assembly equipment and the fragile optical fibers. It provides a controlled mounting interface that minimizes mechanical stress and prevents direct contact between automated tools and the fibers.
3Ease of manufacture
If conventional optical module design is used, then manufacturing simplicity is maintained, but space management and thermal management performance deteriorate
Solution Approach 1:
The holder is designed to be integrated within the existing module housing structure. It nests within the housing and substrate assembly, utilizing available space efficiently without requiring additional external dimensions. The compact design allows multiple components to be nested within a reduced footprint.
Solution Approach 2:
The holder utilizes three-dimensional space within the module housing rather than expanding the two-dimensional footprint. It implements vertical stacking and multi-level mounting structures that manage space in the depth dimension, reducing the overall module area while maintaining manufacturing feasibility.
