Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional optical fiber array devices are used, then the device structure is simple, but the positional accuracy of optical fibers is lower than desired
Solution Approach 1:
The device is segmented into distinct functional modules: substrate, cover plate, ceramic ferrule array, and positioning members. Each component has a specific function, with the positioning members providing precise spacing between ceramic ferrules while the substrate and cover plate provide structural support. This segmentation allows high precision in fiber positioning without requiring the entire device to be complex.
Solution Approach 2:
Positioning members act as intermediary elements between the ceramic ferrules, providing precise spacing and alignment. These positioning members are the key intermediary components that enable accurate fiber positioning without requiring complex direct coupling between ferrules, thus improving manufacturing precision while keeping the overall structure manageable.
2Reliability
If traditional optical fiber array devices are used, then the production cost is low, but the optical signal transmission quality is affected due to lower positional accuracy
Solution Approach 1:
The ceramic ferrules are pre-positioned and fixed on the substrate with precise spacing before the optical fibers are inserted. The positioning members are already in place to ensure correct alignment. This preliminary positioning action ensures high optical signal transmission quality without requiring complex post-assembly adjustments, making the manufacturing process more cost-effective.
Solution Approach 2:
The spacing between ceramic ferrules is precisely controlled by the positioning members, maintaining a specific distance that optimizes optical signal transmission. By controlling this critical parameter (spacing) through simple positioning members rather than complex mechanisms, the device achieves high reliability without significantly increasing manufacturing cost.

AI summary
An optical fiber array device includes a substrate, a cover plate, and a ceramic ferrule array. A receiving groove is defined in one surface of the substrate. The substrate and the cover plate are coupled together and cover the receiving groove. The receiving groove includes a first groove wall and a second groove wall. The ceramic ferrule array includes at least one layer of ceramic ferrules and a number of positioning members. Opposite sides of the at least one layer of ceramic ferrules respectively abut the first groove wall and the second groove wall. Each of the positioning members is located between two adjacent ceramic ferrules.
