Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If miniaturization of optical components and high-density mounting are implemented, then the pluggable optical module achieves compact size and improved integration, but the design and fabrication process becomes more complicated and sophisticated
Solution Approach 1:
The housing is divided into a component mounting section and an optical fiber housing section. This segmentation allows independent optimization of each section: the component mounting section can accommodate miniaturized components in high density, while the optical fiber housing section provides dedicated space for fiber routing, reducing overall design complexity
Solution Approach 2:
The patent introduces a spatial separation by extending the optical fiber housing section in a direction extending from the component mounting section. This dimensional arrangement allows fibers to be routed in a separate spatial zone, reducing interference with compact component layouts and simplifying the fabrication process
2Volume of moving object
If optical fibers are disposed in narrow spaces between optical components, then the module achieves compact integration, but the optical fiber may be broken due to excessive bending
Solution Approach 1:
The optical fiber housing section extracts the fiber routing function from the crowded component mounting space. By providing a dedicated housing section for optical fibers, the design separates fiber paths from component locations, allowing fibers to maintain proper bend radii without interfering with compact component arrangements
Solution Approach 2:
The optical fiber housing section acts as an intermediary structure between the component mounting section and the external fiber connections. This intermediate zone provides controlled routing paths that protect fibers from excessive bending while maintaining compact overall module dimensions
3Volume of moving object
If optical fibers are forcibly housed in the housing, then the module achieves compact integration, but interference between optical fiber and optical component may occur causing damage or breakage
Solution Approach 1:
The housing is segmented into distinct functional zones: a component mounting section for optical components and an optical fiber housing section for fiber routing. This spatial segmentation prevents interference between fibers and components while maintaining compact integration
Solution Approach 2:
The optical fiber housing section extends in a direction from the component mounting section, creating a three-dimensional arrangement that separates fiber paths from component locations. This dimensional separation eliminates harmful interference while achieving compact module size
