Optical Module Connector Assembly Sliding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of inner optical fibers in short optical wiring for silicon photonics optical modules faces challenges due to length variations and stored spring force, which can deform adhesives and affect bonding reliability, leading to performance degradation.
Innovation Solution
The optical module design incorporates a housing with a slid surface and engaging protrusions that allow the connector assembly to be positioned and fixed according to the natural length of the inner optical fiber, minimizing spring force and adhesive deformation by using a sawtooth-shaped engaging portion and inclined surfaces for precise alignment and fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the inner optical fiber is used in short optical wiring, then the wiring length is reduced, but length variations and stored spring force cause adhesive deformation and bonding reliability degradation
Solution Approach 1:
The connector assembly is designed with a sliding mechanism that allows dynamic adjustment of the connector position along the optical fiber. This enables the system to accommodate length variations in the optical fiber while maintaining proper bonding conditions, resolving the contradiction between short wiring length and bonding reliability
Solution Approach 2:
The patent changes the positional parameter of the connector assembly along the optical fiber to accommodate length variations. By allowing the connector to be positioned at different locations, the system maintains reliable bonding despite variations in optical fiber length, thus resolving the contradiction
2Manufacturing precision
If the connector assembly position is fixed, then bonding precision is improved, but length variations of the optical fiber cannot be accommodated
Solution Approach 1:
The connector assembly incorporates a sliding mechanism that provides dynamic positioning capability. This allows the connector to be positioned precisely for bonding while also accommodating length variations, thus resolving the contradiction between bonding precision and adaptability to length variations
Solution Approach 2:
The housing is divided into a fixed portion and a movable portion, allowing the connector assembly to slide within the housing. This segmentation enables precise positioning for bonding while accommodating optical fiber length variations, resolving the contradiction between precision and adaptability
