Optical Fiber Holder With Segmented Grooves For Pitch Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to reliably arrange optical fibers with a reduced outer diameter of 0.20 mm in V grooves of fusion machines with a standard pitch of 0.25 mm, as existing holders struggle to accommodate different arrangement pitches, requiring costly and time-consuming redesigns of fusion machines.
Innovation Solution
The optical fiber holder features a housing portion with linear protrusions and constant-width grooves that allow optical fibers to be arranged in parallel, with adjustable protrusion widths and section spacings to accommodate varying pitch differences, ensuring all fibers can be placed in V grooves, even with machines having different arrangement pitches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If optical fibers with reduced outer diameter (0.20 mm) are arranged in V grooves with standard pitch (0.25 mm), then the arrangement pitch compatibility is improved, but the alignment reliability deteriorates due to pitch mismatch
Solution Approach 1:
The holder body is divided into multiple grooves with different widths along the longitudinal direction. The groove width varies to accommodate different arrangement pitches of optical fibers, allowing the same holder to handle both 0.20mm and 0.25mm pitch fibers by selecting appropriate grooves
Solution Approach 2:
Different regions of the holder body have different groove widths tailored to specific pitch requirements. Each groove is locally optimized with a width matching the arrangement pitch of the optical fibers it will accommodate, ensuring proper alignment and reliability for each fiber type
2Adaptability or versatility
If existing holders are redesigned to accommodate different arrangement pitches, then the adaptability is improved, but the manufacturing cost and time increase
Solution Approach 1:
The holder body is designed as a universal component with multiple grooves of varying widths that can accommodate different optical fiber arrangement pitches (0.20mm, 0.25mm, and others). This multi-functional design eliminates the need for separate holders for different pitch requirements, reducing manufacturing complexity and cost
3Ease of manufacture
If the groove width is standardized, then the manufacturing simplicity is improved, but the adaptability to different fiber pitches deteriorates
Solution Approach 1:
Instead of a single standardized groove width, the holder incorporates multiple segmented grooves with different widths. Each groove is individually sized to match specific pitch requirements, providing adaptability while maintaining relatively simple manufacturing processes for each groove type

AI summary
Provided is an optical fiber holder comprising a holder body and a cover. The holder body has an accommodation section capable of accommodating a plurality of optical fibers. The holder body or the cover has at least one ridge which can be disposed within the accommodation section. When the cover is closed over the holder body, a plurality of sections which can parallelly accommodate the plurality of optical fibers are parallelly formed by the inner surface of the accommodation section, the lower surface of the cover, and the ridge.
