Modular Splice Enclosure Cable Management System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable management systems for splice enclosures face challenges in maintaining alignment and secure connection of multiple fiber optic cables under varying forces and orientations, lacking flexibility and expandability to accommodate different installations.
Innovation Solution
A modular cable management system comprising a cap and base with clamps and interlock portions, along with cable guides, that allows for alignment and secure positioning of cables through ports, enabling expansion to support multiple cables and maintaining connection integrity by using a fastener to prevent separation of cable guides from the cap and base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a modular cable management system with separate cable guides and base is used, then adaptability and ease of installation are improved, but device complexity increases due to multiple components that need to be assembled and interconnected
Solution Approach 1:
The cable management system is divided into separate modular components including cable guides, base, and cap that can be independently manufactured, installed, and configured. Each cable guide can be separately attached to the base and positioned to manage individual cables, allowing the system to adapt to different cable routing requirements without replacing the entire assembly.
Solution Approach 2:
The base is designed with multiple attachment points and interlock portions that can accommodate various cable guide configurations. The standardized interface between components allows the same base to support different numbers and arrangements of cable guides, making the system universally applicable to multiple installation scenarios.
2Reliability
If clamps are used to maintain cable alignment with ports, then connection reliability is improved, but device complexity increases due to additional alignment mechanisms
Solution Approach 1:
Cables are pre-aligned with their respective ports using clamps before the cap is installed. The clamps secure the cables in the correct position, and the cap is then placed to enclose and protect this pre-established alignment. This preliminary alignment action ensures reliable connections without requiring complex real-time adjustment mechanisms.
Solution Approach 2:
The clamp design allows cables to self-align with the ports through the mechanical constraint provided by the clamp structure. Once the cable is inserted and clamped, the geometry of the clamp and port interface automatically maintains proper alignment without requiring additional active control or adjustment mechanisms.
3Reliability
If interlock portions and fasteners are used to prevent separation of components, then connection reliability is improved, but ease of manufacture worsens due to additional assembly steps and fastening mechanisms
Solution Approach 1:
The interlock system is segmented into male and female portions that are integrally formed with the base and cable guide components respectively. This segmentation allows each component to be manufactured independently using standard molding techniques, and the interlocking geometry provides reliable mechanical connection without requiring additional fasteners or assembly steps for the interlock portions themselves.
Solution Approach 2:
The fastener function is merged with the cap component, which serves dual purposes: enclosing the cables that have been aligned by the clamps and simultaneously fastening the entire cable management assembly to the conduit body. This merging eliminates the need for separate fastening operations and reduces the total number of components.

AI summary
A cable management system includes a cap that cooperates with a housing to enclose a connection between a first cable and a second cable. The cap defines a first port and a second port through which cables extend into the housing. A base is to be coupled to the cap. The base includes a first clamp that protrudes from a surface of the base and maintains an alignment of a portion of the first cable with the first port. The base also includes a base interlock portion. A first cable guide, separate from the base, is to be installed on the cap to maintain an alignment of a portion of the second cable. The first cable guide includes a second clamp, and a first cable guide interlock portion that cooperates with the base interlock portion to interfere with separation of the first cable guide from the base.
