Surface-Embedded Tubular Communication Lines With Cured Protectant
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of communication lines, such as fiber optic cables, is challenging due to the need for long-distance deployment, protection from the environment, and hiding from view, which often results in high costs, disruption, and safety risks associated with traditional installation methods like trenching and micro-trenching.
Innovation Solution
A method and apparatus for embedding a tubular assembly into a constructed surface by forming a recess and applying a protectant to encase the assembly, using a surface modification tool to create a recess and a protectant applicator to adhere and encase the tubular assembly, allowing it to be partly or fully embedded with a protective layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional trenching or micro-trenching methods are used to install communication cables, then the cable can be protected and deployed over long distances, but the installation process causes significant surface disruption, requires heavy machinery, and increases installation costs
Solution Approach 1:
The patent changes the physical state of the protectant material from uncured (liquid or semi-liquid) to cured (solid), allowing it to flow around the cable and then harden to provide protection without requiring trenching or heavy machinery. This phase change enables the protectant to adapt to the cable's shape and the surface contours.
Solution Approach 2:
The patent uses a composite system consisting of the communication cable embedded within the protectant material. The protectant material itself may be a composite formulation that combines adhesive properties with protective characteristics, creating a unified structure that adheres to the surface while protecting the cable.
2Reliability
If armor and protective materials are added to communication cables, then the cable protection is improved, but the weight, fabrication cost, and installation footprint increase
Solution Approach 1:
The protectant material serves as an intermediary between the cable and the external environment. Instead of adding heavy armor directly to the cable, the protectant material acts as a protective layer that adheres to the surface, providing environmental protection while keeping the cable itself lightweight and easy to handle.
Solution Approach 2:
The patent changes the protection approach from adding substantial physical armor to applying a protective coating or encasement. The protectant material transitions from uncured to cured state, providing protection through material properties rather than through added mass and structural complexity.
3Reliability
If communication cables are installed using micro-trenching with diamond saw blades, then the cable can be protected, but the installation process creates safety risks to workers and may damage existing utility lines
Solution Approach 1:
The patent replaces the mechanical trenching system (diamond saw blades, heavy machinery) with a chemical/physical process involving the application and curing of protectant material. This substitution eliminates the need for cutting tools and heavy equipment, thereby removing the associated safety risks and potential damage to existing utilities.
Solution Approach 2:
The protectant material serves as an intermediary that provides cable protection without requiring direct contact between installation equipment and the installation environment. The material is applied in uncured form, allowing easy manipulation and placement, then cures to provide protection, avoiding the need for mechanical cutting or trenching operations.
4Productivity
If conventional cable installation methods are used, then the cable can be deployed, but the installation process requires multiple machines and complex procedures, increasing installation time and cost
Solution Approach 1:
The patent merges multiple installation functions into a single process: the protectant material application simultaneously provides adhesion to the surface, protection for the cable, and structural support. The curing process integrates the cable installation with the protectant hardening, eliminating the need for separate trenching, cable laying, and backfilling operations.
Solution Approach 2:
The protectant material performs multiple functions: it adheres the cable to the surface, protects the cable from environmental factors, provides structural support, and creates a finished surface. This multi-functionality eliminates the need for separate equipment and procedures for each function, simplifying the overall installation process.

AI summary
The subject matter of this specification can be embodied in, among other things, a method for adhering a tubular assembly onto a constructed surface, and the method includes removing a portion of the constructed surface to form a recess below a major plane of the constructed surface, arranging the tubular assembly partly within the recess, applying an uncured protectant, and curing the uncured protectant to protectively encase the tubular assembly.
