Cylindrical Drop Box Assembly for Pole Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drop boxes for optical telecommunications networks are not satisfactorily designed for pole mounting, as they are quadrangular and do not match the cylindrical shape of poles, leading to unstable fixation, cable entanglement, and visible fixation elements that are vulnerable to vandalism and theft.
Innovation Solution
A drop box assembly with a cylindrical holding part featuring wings that embrace the pole, hidden fixation elements, and tapered design to accommodate various pole diameters, ensuring secure and stable mounting while keeping fixation elements concealed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a quadrangular drop box is mounted to a cylindrical pole using conventional brackets and screws, then the drop box can be fixed to the pole, but the fixation is inherently unstable and the fixing elements remain visible and accessible
Solution Approach 1:
The holding part is designed with a curved outer surface that matches the cylindrical shape of the pole, replacing the conventional flat bracket design. This curved structure embraces the pole and provides stable fixation while hiding the mounting elements from external access.
Solution Approach 2:
The holding part acts as an intermediary component between the quadrangular drop box and the cylindrical pole. It features a curved outer surface for pole contact and a flat inner surface for box attachment, mediating between the two incompatible geometries while providing stable and concealed mounting.
2Adaptability or versatility
If drop boxes are mounted above one another on crowded poles, then more operators can be accommodated, but cables from upper boxes turn around lower boxes causing unsuitable bending
Solution Approach 1:
The holding part includes integrated cable routing features that guide cables in a vertical dimension along the pole surface, preventing them from turning around lower boxes. This dimensional approach to cable management maintains proper bending radii even when multiple boxes are stacked vertically.
3Ease of manufacture
If conventional flat brackets are used to mount quadrangular drop boxes to cylindrical poles, then mounting is possible, but the shape mismatch prevents firm fixation
Solution Approach 1:
The holding part features a curved outer surface that conforms to the cylindrical pole geometry, replacing flat brackets. This curvature enables firm contact and stable fixation while maintaining ease of installation through a simple wrapping and fastening process.
