Adhesive-Backed Cable Duct for In-Wall Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connecting existing multi-dwelling units to Fiber-to-the-X networks is challenging due to difficulties in routing cables within walls or floors, limited distribution space, and the need for upgrading in-home cabling, which increases costs and complexity.
Innovation Solution
Adhesive-backed communications media cabling with a duct having a conduit portion and a flange with an adhesive layer for mounting, allowing for the distribution of multiple communications media lines, including optical fibers, Ethernet, and HDMI lines, within living units without the need for conventional fasteners, and a multimedia receptacle system for discreet mounting and routing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cabling methods are used to route cables within walls or floors, then reliable connections are achieved, but installation complexity and labor costs increase significantly
Solution Approach 1:
The patent extracts the cabling operation from the complex process of fishing cables through walls and floors. By providing pre-installed conduits during construction, the cabling task is simplified to merely inserting cables into the existing conduits, eliminating the need for difficult drilling, routing, and securing operations through building structures.
Solution Approach 2:
The conduits are installed in advance during the building construction phase, before the cabling needs to be routed. This preliminary action creates ready-made pathways that simplify subsequent cable installation, transforming a complex post-construction task into a simple plug-and-play operation.
2Productivity
If adhesive-backed ducts are used for mounting, then installation time and labor costs are reduced, but mounting surface preparation requirements increase
Solution Approach 1:
The patent replaces traditional mechanical mounting systems (screws, staples, clips) with an adhesive-based system. The adhesive-backed ducts utilize chemical bonding through pressure-sensitive adhesive layers, eliminating the need for mechanical fasteners and their associated installation steps of drilling, screwing, or stapling.
Solution Approach 2:
The mounting method transitions from mechanical parameters (screw torque, staple depth) to chemical parameters (adhesive bonding strength, surface energy). This parameter change enables simpler installation while requiring appropriate surface preparation for optimal adhesive performance.

Function Achieved in This Case
Reduces labor and installation costs by eliminating the need for fishing cables through walls, simplifies the installation process, and maintains a low aesthetic impact by allowing for discreet and efficient routing of communication lines within living units.
Implementation Method 1
An adhesive layer is disposed on a surface of the flange such that the duct is mountable to a mounting surface via the adhesive layer

AI summary
An adhesive-backed communications media cable includes a duct having a conduit portion with a lengthwise bore formed therein. The conduit portion includes an Ethernet over twisted pair communication line. The duct also includes a flange extending lengthwise with the conduit portion. An adhesive layer is disposed on a surface of the flange such that the duct is mountable to a mounting surface via the adhesive layer. A system for distributing multiple communications media lines in a living unit includes a multimedia receptacle mountable on a wall or mounting surface and an adhesive-backed communications media duct.
