Unibody Cable Sealing Device for Telecommunication Enclosures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable sealing devices for telecommunication enclosures are often sold separately, requiring multiple parts and additional costs for managing various cable sizes, which complicates installation and increases expenses, especially with the rapid deployment of FTTx networks needing affordable and easy-to-use solutions.
Innovation Solution
A unibody cable sealing device with a rigid body and elastomeric portion, featuring a removable closure for easy insertion and sealing of optical fiber cables, reducing the need for excess parts and simplifying installation by transforming into a cable sealing device with minor modifications, such as a cable tie, minimizing waste and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional cable sealing devices are sold separately as kits of parts, then versatility for different cable sizes is improved, but device complexity and part management increase
Solution Approach 1:
The patent combines multiple separate components (sealing member, cable securing device, compression member) into a single integrated cable sealing device. The sealing member is positioned within the body, the cable securing device is attached to compress the sealing member, and all components are pre-assembled as one unit rather than requiring separate assembly from a kit of parts.
Solution Approach 2:
The cable sealing device is designed with adjustable features that allow it to accommodate different cable sizes and types. The compression member can be adjusted to provide appropriate compression force for various cable diameters, and the cable securing device can accommodate different cable configurations, making the single device versatile for multiple applications.
2Adaptability or versatility
If multiple separate parts are used for cable sealing, then adaptability to different cable sizes is improved, but ease of operation deteriorates
Solution Approach 1:
The cable sealing device is pre-assembled with the sealing member, cable securing device, and compression member already in place. This preliminary assembly eliminates the need for field assembly of multiple components, reducing installation time and complexity while maintaining the ability to accommodate different cable sizes through adjustable features.
3Adaptability or versatility
If excess parts are included in sealing kits for various cable sizes, then adaptability is improved, but loss of substance increases
Solution Approach 1:
The cable sealing device incorporates adjustable parameters that allow a single device to accommodate a range of cable sizes. The compression member and cable securing device can be adjusted to work with different cable diameters and configurations, eliminating the need for multiple pre-configured sealing components for different cable sizes and reducing material waste.
