Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical fiber bending devices struggle to align optical fibers accurately between recessed and projecting holding members, leading to inconsistent leak light measurement due to variations in fiber position, especially for fibers with smaller diameters.
Innovation Solution
Incorporating a supplemental support mechanism with a positioning protrusion and urging members to align the optical fiber to the center of light receiving elements, ensuring stable leak light measurement by adjusting the fiber's position and bending between the recessed and projecting holding members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple fiber holding mechanism with recessed and projecting members is used, then the device structure is simple, but the optical fiber alignment precision is poor leading to inconsistent leak light measurement
Solution Approach 1:
The optical fiber itself serves as the alignment reference by utilizing its outer diameter dimension. The fiber's physical presence guides its own positioning between the recessed and projecting holding members, eliminating the need for external alignment mechanisms while ensuring consistent alignment across different fiber diameters.
Solution Approach 2:
The holding member dimensions are designed to accommodate varying fiber outer diameters. The recessed and projecting members are sized to match the fiber's outer diameter, allowing the system to adapt to different fiber parameters while maintaining precise alignment and consistent leak light measurement across various fiber types.
2Adaptability or versatility
If the recessed and projecting holding members are designed for general use, then the device has good adaptability to different fiber diameters, but the alignment precision for smaller diameter fibers deteriorates
Solution Approach 1:
The fiber's own outer diameter serves as the alignment reference. By designing the holding members to interface with the fiber's outer diameter, the system enables self-alignment that works consistently across all fiber diameters, including small diameter fibers, without requiring diameter-specific adjustment mechanisms.
Solution Approach 2:
The recessed and projecting holding members are designed with specific local geometries that match the fiber's outer diameter characteristics. This localized design ensures that the critical alignment interface adapts to different fiber diameters while maintaining precise positioning for leak light measurement.

AI summary
A device for bending an optical fiber and receiving light is provided with a recessed holding member having a recess, a projecting holding member having a projection projecting toward the recess, light receiving elements for receiving leak light from an optical fiber held between the recess and the projection, and a supplemental support mechanism that is substantially independent of the recess or the projection and supplementarily supports the optical fiber between the recess and the projection such that the leak light from the optical fiber is received by center of the light receiving elements.
