Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical coupling devices face challenges in resisting both longitudinal and transverse components of external forces applied to optical fibers, which can lead to damage and disruption of the optical coupling.
Innovation Solution
The optical coupling device incorporates a specific structure with a holder and resin bodies of varying Young's moduli to secure optical fibers, where a first resin body with a higher modulus resists longitudinal forces and a second resin body with a lower modulus absorbs transverse forces, minimizing deformation transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single resin body is used to secure optical fibers, then the structure is simple, but it cannot effectively resist both longitudinal and transverse external forces
Solution Approach 1:
The holder is divided into multiple components: a first resin body for securing optical fibers to the holder body, and a second resin body for securing optical fibers to the cover. This segmentation allows each resin body to specialize in resisting different force components, with the first resin body primarily resisting longitudinal forces and the second resin body primarily resisting transverse forces, thereby achieving comprehensive force resistance without requiring a single overly complex structure
Solution Approach 2:
Different regions of the holder are assigned different resin materials with optimized properties. The first resin body uses a material with higher Young's modulus to resist longitudinal deformation, while the second resin body uses a material with lower Young's modulus to absorb transverse forces. This local differentiation of material properties enables each region to optimally handle the specific forces it encounters
2Strength
If a rigid resin body is used to secure optical fibers, then longitudinal force resistance is improved, but transverse force transmission causes deformation
Solution Approach 1:
The Young's modulus parameter of the resin material is specifically optimized for different functional regions. The first resin body uses a material with higher Young's modulus (1-10 GPa) to resist longitudinal forces, while the second resin body uses a material with lower Young's modulus (0.1-1 GPa) to absorb transverse forces. This parameter differentiation allows each resin body to optimally handle its specific force component without causing harmful deformations
Solution Approach 2:
The holder employs composite material construction with two different resin materials having distinct mechanical properties. This composite approach combines the advantages of both materials: the high-modulus resin provides longitudinal strength while the low-modulus resin provides transverse compliance, achieving comprehensive mechanical performance that neither material could provide alone
