Transition Coupling Assembly for Smooth Conduit Wiring in Concrete Slabs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for joining conduit sections, particularly in concrete slabs, are inefficient and do not facilitate smooth wiring routing due to non-uniform diameters and damage issues.
Innovation Solution
A transition coupling with tapered end sections is used to join PVC conduit sections, ensuring uniform diameters and secure assembly, allowing for efficient wiring passage and adaptability across various conduit sizes.

Engineering Contradiction Analysis
1Ease of operation
If conventional joining methods are used for conduit sections in concrete slabs, then assembly can be completed, but the wiring routing is not smooth and assembly efficiency is low due to non-uniform diameters
Solution Approach 1:
A transition coupling acts as an intermediary component between conduit sections with different diameter conditions. The transition coupling includes a first end portion that fits into a reamed conduit section and a second end portion that connects to another conduit section, thereby mediating the connection and ensuring smooth wiring routing throughout the assembly.
Solution Approach 2:
The transition coupling employs parameter changes in its geometry, specifically varying the inside diameter along its length. The first portion has a larger inside diameter to accommodate reamed conduit sections, while the second portion has a smaller inside diameter matching standard conduit sections. This parameter variation enables smooth transitions and efficient wiring routing.
2Reliability
If conduit sections are joined without transition couplings, then assembly is simpler, but damage occurs and assembly durability is reduced
Solution Approach 1:
The transition coupling is segmented into distinct functional portions: a first end portion for receiving and securing to reamed conduit sections, a second end portion for connecting to standard conduit sections, and intermediate sections that facilitate the transition. This segmentation allows each portion to be optimized for its specific function, improving overall assembly durability.
Solution Approach 2:
The transition coupling is designed to be installed before final conduit section assembly, with the first end portion预先 (in advance) fitted into the reamed conduit section. This preliminary action prevents damage during subsequent assembly operations and ensures proper alignment and secure connection.
3Productivity
If standard conduit sections are used without transition couplings, then assembly is faster, but wiring efficiency is reduced due to non-uniform diameters
Solution Approach 1:
The transition coupling serves multiple functions within a single component: it connects conduit sections of different diameter conditions, maintains structural integrity, ensures smooth wiring routing, and provides a secure mounting interface. This multi-functionality improves wiring installation efficiency without requiring multiple separate components.

AI summary
A conduit transition coupling facilitates connection of tubing with a conduit section through which associated electrical wiring and/or cables are routed. The assembly method includes providing a conduit transition coupling, which is joined to the conduit section which is positioned in an associated concrete slab or the like. The conduit coupling assembly thus particularly facilitates routing of wiring from a conduit section positioned within a concrete slab or like flooring element, through the conduit transition coupling, and associated conduit or tubing.
