Plastic Optical Module Pivot Guide for Fiber Stress Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pivoting optical telecommunication modules made of plastic material lack guide elements for optical fibers at the interface with the support part, leading to potential damage due to rotational movements.
Innovation Solution
Incorporating a concave curved wall or guide channel with retaining tabs upstream of the pivot axis to guide and secure optical fibers, reducing stress and facilitating assembly, while allowing reversible mounting on either side for standardization and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the module is designed to pivot relative to the support piece, then the module can be easily installed and repositioned, but the optical fibers are subjected to rotational movements that can cause damage
Solution Approach 1:
The device is divided into a fixed support piece and a pivoting module that can be independently assembled and disassembled. The support piece remains stationary while the module pivots, separating the stable mounting function from the repositioning function.
Solution Approach 2:
Optical fiber guide elements are introduced as intermediaries between the pivoting module and the fixed support piece. These guide elements channel and constrain the optical fibers along a controlled path during pivoting, preventing uncontrolled movements that would damage the fibers.
2Reliability
If guide elements are added to protect optical fibers during pivoting, then fiber damage is prevented, but the device complexity increases
Solution Approach 1:
The optical fiber guide elements are integrated into the pivoting module structure itself rather than being separate components. The guide channels are molded directly into the module housing, combining the protective function with the existing structural elements.
Solution Approach 2:
The guide elements serve multiple functions: they protect optical fibers from damage, define the pivoting path, and maintain proper alignment between the module and support piece. This multi-functionality reduces the need for additional dedicated components.
3Stability of the object's composition
If the support piece is fixed to the mounting frame, then stability is achieved, but assembly and disassembly become difficult
Solution Approach 1:
The support piece is designed with pre-formed engagement features (such as clips or mounting tabs) that allow it to be quickly attached to and detached from the mounting frame. This preliminary design of the mounting interface enables stable fixation during operation while facilitating easy assembly and disassembly.
