Divided Conduit with Embedded Strip Films for Cable Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conduit systems face difficulties in efficiently inserting a second cable due to tangling and twisting with the first cable, especially over long distances and through undulations or planned curves, leading to damage and inefficient use of space.
Innovation Solution
A divided conduit with strip-shaped films embedded into its inner walls, creating flexible longitudinal channels to separate the conduit into sections, allowing for easier cable insertion and reducing friction and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single conduit is used to protect cables underground, then cable protection from weather and damage is improved, but inserting a second cable becomes difficult due to tangling and twisting with the first cable
Solution Approach 1:
The conduit is divided into multiple separate channels using strip-shaped dividers, creating distinct pathways for different cables. This segmentation prevents cables from tangling and twisting while maintaining the protective enclosure, allowing multiple cables to be installed independently without interfering with each other.
2Ease of operation
If a divider is inserted into an existing conduit to separate sections, then cable insertion becomes easier, but the divider cannot be placed in undulations or planned curves
Solution Approach 1:
The strip-shaped dividers are made from flexible materials that can bend and conform to undulations and curves in the conduit. This flexibility allows the dividers to be installed in conduits with various configurations while still providing effective separation between cable channels.
3Productivity
If multiple cables are installed in the same conduit, then space utilization is improved, but friction and heat build-up increase causing cable damage
Solution Approach 1:
By dividing the conduit into separate channels, each cable occupies its own dedicated space with reduced contact with other cables. This segmentation decreases friction between cables and improves heat dissipation by providing better airflow and thermal management in each channel, preventing heat build-up that could damage the cables.

Function Achieved in This Case
The divided conduit design prevents cable snagging and heat build-up, reduces contact and alternation losses, and allows for improved space utilization by enabling easier installation of additional cables without damage.
Implementation Method 1
extruding a molten thermoplastic polymer into the form of an at least partially molten conduit
Implementation Method 2
placing at least one strip-shaped substrate within the at least partially molten conduit during or directly after conduit formation such that the first longitudinal and second longitudinal edges of the strip-shaped substrate embed into the inner surface of the conduit
