Removable Adhesive Duct for MDU Cable Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting multiple dwelling units (MDUs) to FTTX networks face challenges such as gaining building access, limited distribution space, and the need for skilled labor and expensive equipment, leading to increased costs and service disruptions due to the complexity of cable routing and management within MDUs.
Innovation Solution
A duct with a removable adhesive layer is designed to facilitate the installation and removal of communication lines, featuring a flexible elongated body with a conduit for communication lines and a stretch release adhesive that allows for easy detachment without damaging the mounting surface, enabling efficient cable management and reduced installation time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional adhesive methods are used to mount ducts, then secure attachment is achieved, but removal damages the mounting surface
Solution Approach 1:
The adhesive layer undergoes a parameter change from a permanent bonding state to a removable state through the introduction of a release layer. The release layer modifies the adhesive properties, allowing the duct to be securely mounted during service while enabling clean removal when needed, thus resolving the contradiction between attachment security and removal capability.
Solution Approach 2:
The adhesive mounting system is segmented into multiple functional layers: an adhesive layer for bonding and a release layer for controlled removal. This segmentation allows each layer to perform its specific function - the adhesive layer provides secure attachment while the release layer enables damage-free removal, eliminating the need to choose between permanent bonding and easy removal.
2Reliability
If skilled labor and expensive equipment are used for cable routing and splicing, then connection reliability is improved, but installation costs and time increase
Solution Approach 1:
Cables are pre-routed through the duct during the initial duct installation phase, eliminating the need for later cable routing and splicing operations. This preliminary action allows cables to be installed in advance before final connections are made at customer premises, significantly reducing the need for skilled splicing labor and expensive fusion equipment while maintaining connection reliability.
Solution Approach 2:
The complex cable routing and splicing operations are extracted from the installation process and replaced by the simpler duct installation method. Instead of installing individual cables and making splices on-site, the system extracts these complex tasks by pre-installing the duct infrastructure that guides cables directly to their destinations, reducing both labor skill requirements and installation time.
3Stability of the object's composition
If ducts are permanently mounted to mounting surfaces, then stable positioning is achieved, but aesthetic challenges and physical obtrusiveness increase
Solution Approach 1:
The mounting system transitions from a static permanent attachment to a dynamic removable attachment. The duct can be securely mounted when needed for stable positioning, yet easily removed or repositioned to maintain aesthetic quality. This dynamic capability allows the system to adapt between stability and aesthetics based on operational requirements.
Solution Approach 2:
The release layer acts as an intermediary between the duct and the mounting surface, mediating between the need for stable positioning and the desire for aesthetic quality. This intermediary layer enables the duct to be securely attached during service while allowing for clean removal that leaves no damage or unsightly residue, thus resolving the aesthetic challenges of permanent mounting.

AI summary
A duct for distributing one or more telecommunication lines comprises an elongated body having a length and a conduit portion with a lengthwise bore formed therein. The conduit portion contains one or more telecommunication lines. The duct also includes a flange extending lengthwise adjacent the main body to mount the duct to a mounting surface, such as a wall. The duct also includes an adhesive layer disposed on a surface of the flange, the adhesive layer comprising a removable adhesive to permit removal of the duct from the mounting surface after mounting.
