Rotatable Optical Termination Module for DIN Rail Cabinets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric home cabinets are not designed to manage optical cables and termination modules efficiently, leading to entanglement issues with electrical cables and difficulty in accessing optical connectors due to fixed inclinations and lack of fiber management solutions suitable for DIN rail mounting.
Innovation Solution
An optical termination module with a fixed part attached to a guiding member and a movable part that can rotate to adjust the orientation of optical connectors, allowing for easy access and storage of excess fibers, reducing the likelihood of cable entanglement with electrical cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If optical termination modules are mounted on DIN rails in electric cabinets, then space utilization is improved, but accessibility of optical connectors deteriorates due to fixed inclination and limited space between rows of guides
Solution Approach 1:
The optical termination module incorporates a rotatable support structure that allows the module to be rotated between a first position (for mounting on DIN rail) and a second position (for accessibility). This dynamic transformation enables the module to adapt its orientation based on operational requirements, resolving the contradiction between space utilization and connector accessibility.
2Area of stationary object
If optical cables are managed in compact cabinet spaces, then space efficiency is improved, but cable entanglement with electrical cables increases
Solution Approach 1:
The rotatable support structure allows optical cables to be routed and positioned in different spatial configurations. By rotating the module to the appropriate position, operators can manage cable routing to minimize entanglement with electrical cables while maintaining compact space utilization.
3Ease of manufacture
If optical connectors are mounted with fixed inclination, then manufacturing simplicity is improved, but operational efficiency deteriorates due to difficulty in handling and inspection
Solution Approach 1:
The rotatable support structure enables the optical termination module to be mounted with a fixed inclination for manufacturing simplicity, yet allows rotation during operation to achieve optimal handling and inspection angles. This dynamic adjustment capability maintains manufacturing simplicity while significantly improving operational efficiency.
4Productivity
If connector ports are front-mounted, then connection speed is improved, but cable management deteriorates due to tangling in the cabinet
Solution Approach 1:
The rotatable support structure allows the module to be positioned optimally during connection operations (front-mounted position for speed) and then rotated to a different position for cable management (reducing tangling). This dynamic repositioning capability maintains fast connection speed while simplifying cable management.
