Optical Fiber Winding Bobbin With Rib Magazine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for winding excess optical fibre lengths onto bobbins are either time-consuming and costly due to manual operation or require additional components that complicate unwinding and risk damaging the fibre.
Innovation Solution
A bobbin design with a cylindrical reel, radial rims, and a magazine featuring a circumferential edge with an opening and a radial rib, allowing for automatic winding and secure storage of excess fibre length without manual intervention, using a device with coaxial discs and a robotic arm for efficient winding and easy access for unwinding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual winding method is used, then the excess length can be wound onto the magazine, but the operation takes a long time and is costly
Solution Approach 1:
The magazine is designed with a rib that automatically guides and secures the optical fibre during winding, eliminating the need for manual positioning and securing operations. The structure self-regulates the fibre placement without human intervention.
Solution Approach 2:
The rib acts as an intermediary element between the circumferential edge and the optical fibre, facilitating automatic winding by guiding the fibre onto the magazine surface and positioning it correctly without requiring manual handling.
2Extent of automation
If a removable plate is added to wedge the free end, then automatic winding can be achieved, but the unwinding becomes difficult and risks damaging the fibre
Solution Approach 1:
Instead of wedging the fibre from the inside (which complicates unwinding), the rib structures the winding from the outside, allowing the fibre end to remain accessible and easily removable without damaging the fibre or the winding structure.
Solution Approach 2:
The magazine structure is segmented with a rib that creates a distinct winding zone, separating the fibre storage function from the securing function, which enables both automatic winding and easy unwinding operations.
3Extent of automation
If additional components are added to wedge the fibre, then automatic winding is enabled, but the device complexity increases
Solution Approach 1:
The rib serves multiple functions: it guides the optical fibre during winding, secures the winding in place, and maintains the structural integrity of the magazine, eliminating the need for separate wedging components.
Solution Approach 2:
The rib is integrated directly into the magazine structure, merging the guiding and securing functions into a single structural element rather than adding separate components, thereby reducing overall device complexity.
