Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable mounting systems in fiber optic distribution enclosures face challenges in securely mounting cables while relieving torsional and bending stresses, often requiring tools and mechanical fasteners, and are inefficient for multiple mounting locations.
Innovation Solution
A cable mounting clamp system featuring a base with a tong structure and fork structure that allows tool-free installation, utilizing a roller tube and bridge lances for secure, removable mounting, and includes a strap for additional support, reducing stress and improving ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cable mounting systems are used, then cables can be securely mounted, but torsional and bending stresses are not relieved
Solution Approach 1:
The mounting system is divided into separate functional components: a mounting clamp for secure attachment, a roller tube for reducing bending stress, and bridge lances for positional adjustment. This segmentation allows each component to address specific stress types independently.
Solution Approach 2:
The roller tube acts as an intermediary element between the cable and the mounting clamp, providing a rolling contact surface that reduces bending stresses while maintaining secure mounting through the clamp's mechanical engagement.
2Reliability
If traditional mounting systems with mechanical fasteners are used, then secure mounting is achieved, but tool-free installation is not possible
Solution Approach 1:
The mounting system employs self-clamping mechanisms where the fork structure and tong structure automatically engage and secure the cable without requiring external tools. The spring-loaded tong members automatically adjust to clamp the cable when the fork is inserted.
Solution Approach 2:
The mounting system uses dynamic, spring-loaded tong members that can automatically adjust their clamping force based on the cable size and position. This dynamic adjustment enables secure mounting while maintaining ease of installation through simple insertion and release motions.
3Ease of manufacture
If fixed mounting locations are used, then installation is simplified, but adaptability to multiple mounting locations is reduced
Solution Approach 1:
The fork structure is designed to be slidable along the cable, allowing the mounting location to be dynamically adjusted after installation. This slidable mechanism provides adaptability to different positions while maintaining the simplicity of the overall installation process.
Solution Approach 2:
The mounting system is designed with universal features that allow it to be installed at multiple locations along the cable. The slidable fork and adjustable tong structure enable the same mounting device to accommodate various positions, eliminating the need for location-specific mounting solutions.
4Reliability
If additional mounting plates are used, then mounting security is improved, but device complexity increases
Solution Approach 1:
The mounting function and the stress relief function are merged into a single integrated assembly where the roller tube is positioned within the mounting clamp structure. This merging eliminates the need for separate mounting plates and reduces overall component count while maintaining both security and stress relief functions.

AI summary
A fiber optic distribution enclosure and cable mounting clamp are provided. The enclosure includes a surface having a first bridge extended along a longitudinal direction. The cable mounting clamp including a base removably connectable to the surface. The base includes an outer body which defines an inner channel and a support ramp disposed within the inner channel. The inner channel extends along the longitudinal direction. A tong structure is connected to the base. The tong structure extends along the longitudinal direction and between the inner channel and the surface. A fork structure is slidable along the longitudinal direction and includes a pair of prongs extended along the longitudinal direction. Each prong is in sliding contact with the tong structure. Each prong forms a longitudinal face extending along the longitudinal direction and an angled face extending away from the longitudinal axis and corresponding to an angled face at the tong structure.
