Cable Anchoring Device With Spool And Ratchet Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In fiber optic networks, there is a need for anchoring devices that can securely route fiber optic cables along structures like buildings and poles, capable of withstanding significant downward loading without damaging the cables and preventing slippage, as existing solutions often fail to support loads over 100 pounds effectively.
Innovation Solution
The development of cable clamps with spool receivers and fasteners that securely wrap fiber optic cables around a spool, distributing the load and preventing slippage through a cradle design and textured surfaces, allowing multiple wraps to anchor the cables to structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional cable anchoring methods are used, then installation is simple, but they cannot support loads over 100 pounds and cables slip
Solution Approach 1:
The anchoring device is divided into multiple functional segments: a clamp body for attachment to the structure, a spool for cable wrapping, and a ratchet mechanism for tensioning. This segmentation allows each component to specialize in one function, achieving high load capacity while maintaining reasonable complexity through modular design
Solution Approach 2:
The spool is designed as a curved surface around which the cable wraps multiple times. This curvature distributes the load across the entire wrapped length rather than concentrating it at a single point, enabling the device to support loads exceeding 100 pounds while preventing cable slippage through friction
2Reliability
If cable is wrapped multiple times around spool, then load distribution improves and slippage prevents, but installation complexity increases
Solution Approach 1:
The ratchet mechanism provides self-service tensioning: as the installer pulls the cable through, the ratchet automatically engages to maintain tension and prevent slippage. This self-tensioning feature eliminates the need for complex adjustment mechanisms while ensuring reliable cable security through multiple wraps
Solution Approach 2:
The device is pre-configured with the spool and ratchet mechanism in place, allowing the installer to simply wrap the cable around the spool and pull. The preliminary arrangement of components enables easy installation despite the complex load distribution and slippage prevention features
