Segmented Fiber Optic Cable Clamp for Stacking and Damage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing and protecting optical fiber cables, such as sheet metal saddles and hose clamps, often lead to the loss of clamps during maintenance, limit cable stacking due to weight and fragility, and restrict the capacity for routing additional cables, hindering infrastructure growth and upgrades.
Innovation Solution
A fiber optic clamp with two identical halves featuring a tongue and groove design, made from rigid materials like low-smoke thermoplastics, allowing for easy stacking and secure routing of cables without crushing, and incorporating a zip-tie guide for additional security, which can be manufactured using additive techniques like 3D printing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sheet metal saddles and hose clamps are used to secure optical fiber cables, then the cables can be secured to the cableway, but the clamps are likely to be lost during maintenance and the cables are subject to crushing and breakage
Solution Approach 1:
The clamp is divided into two separate halves that can be independently installed and secured. Each half can be attached to the cableway and cable separately, then joined together to form a complete securing mechanism. This segmentation allows for easier maintenance without losing entire clamp assemblies.
Solution Approach 2:
The two clamp halves are designed to fit together with tongue-and-groove features, creating a nested configuration where one half contains features that receive corresponding features of the other half. This nesting provides secure mechanical retention and prevents loss during maintenance.
2Quantity of substance
If multiple optical fiber cables are stacked directly on top of one another, then more cables can be routed through the cableway, but the weight increases and the fragile glass fibers are at risk of breakage
Solution Approach 1:
Cables are grouped into bundles, with each bundle secured by its own clamp assembly. This segmentation allows multiple cables to be routed through the cableway while distributing the weight and protecting individual cables from direct contact and potential damage from adjacent cables.
3Adaptability or versatility
If traditional saddles and clamps are used, then cables can be secured, but the ability to stack additional cables is limited and expansion of fiber optic capacity is constrained
Solution Approach 1:
The clamp assembly is segmented into two halves that can be independently installed on opposite sides of the cableway. This allows cables to be secured without blocking access to the cableway, enabling future expansion and addition of more cable bundles while maintaining simple installation procedures.
Solution Approach 2:
The clamp design serves multiple functions: it secures cables to the cableway, provides a structured arrangement that facilitates stacking of additional cable bundles, and maintains accessibility for future expansions. The universal design accommodates various cable configurations and expansion scenarios.
