Optical Fiber Unit SZ-Wound Binding Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The binding state of optical fiber units with binding materials wound in an SZ shape tends to be unstable due to unexpected peeling of adhesive parts, leading to potential loosening of fiber bundles and difficulties in intermediate post-branching.
Innovation Solution
The optical fiber unit design features overlapping binding materials with multiple adhesive surfaces disposed at intervals in the longitudinal direction, forming gaps between them, and includes four or more intersection points, with an adhesion length and binding pitch ratio within the range of 0.24 ≤ L/(P/2) ≤ 0.8, and an adhesive strength of 0.114 N to 0.933 N, ensuring stable binding and easy peeling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If binding materials are wound in an SZ shape and adhered at reversed portions, then workability of intermediate post-branching is improved, but the binding state becomes unstable due to unexpected peeling
Solution Approach 1:
The adhesive part is divided into multiple adhesive surfaces (first adhesive surface and second adhesive surface) disposed at intervals in the longitudinal direction. This segmentation allows the binding materials to be adhered at multiple discrete locations rather than a single continuous adhesive region, preventing unexpected peeling while maintaining workability for intermediate post-branching operations.
Solution Approach 2:
The binding materials are preliminarily configured to overlap in a sufficient range with adhesive surfaces disposed at intervals before final assembly. This preliminary arrangement ensures that when the optical fiber unit is subjected to external forces during use, the multiple adhesive surfaces can independently resist peeling, thereby stabilizing the binding state while preserving the ability to perform intermediate post-branching.
2Stability of the object's composition
If binding materials are adhered at reversed portions, then the bundle of optical fibers is prevented from becoming loose, but adhesive parts may be unexpectedly peeled off
Solution Approach 1:
The adhesive bonding is segmented into multiple adhesive surfaces distributed at intervals along the longitudinal direction of the optical fiber unit. This segmentation ensures that if one adhesive surface experiences stress or potential peeling, the other adhesive surfaces continue to maintain the binding, thereby preventing the fiber bundle from becoming loose while enhancing the overall reliability of the adhesive joints.
Solution Approach 2:
By disposing multiple adhesive surfaces at intervals in advance along the longitudinal direction, the invention creates a cushioning effect against unexpected peeling. The distributed adhesive surfaces provide redundant bonding points that can absorb and distribute external forces, preventing catastrophic failure of the adhesive part and ensuring the fiber bundle remains bound.
3Reliability
If multiple adhesive surfaces are disposed at intervals, then external forces are distributed evenly, but manufacturing precision requirements increase
Solution Approach 1:
The binding materials are configured to overlap in a sufficient range, creating a redundant configuration where the exact positioning of adhesive surfaces does not critically affect performance. This overlapping design provides a tolerance buffer that reduces the stringency of manufacturing precision requirements while still achieving even force distribution across multiple adhesive surfaces.
Solution Approach 2:
The invention specifies that adhesive surfaces be disposed at intervals in the longitudinal direction with binding materials overlapping in a sufficient range. By changing the parameter of overlap extent and interval spacing, the design achieves a balance where manufacturing precision requirements are moderated while still providing effective force distribution across multiple adhesive surfaces.
