Parallel-Entry Wiring Chamber for Conduit Body Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical conduit systems are inefficient for wiring operations due to the orientation of access openings, which are often orthogonal to the direction of entry of conduit ports, making it difficult to access wiring for devices remotely located from horizontal conduit runs, especially in industrial settings where infrastructure constraints are common.
Innovation Solution
The design of a top entry conduit body with ports configured to allow wiring access in a direction parallel to the axis of the conduit ports, featuring a wiring chamber with an opening that enables efficient entry and manipulation of wiring, and includes additional ports oriented perpendicular to the passage for enhanced connectivity and safety features like an engagable electrical isolator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the access opening is oriented orthogonal to the conduit ports (conventional design), then the conduit body structure is simple and compact, but wiring access becomes difficult for devices remotely located from horizontal conduit runs
Solution Approach 1:
The patent introduces a wiring chamber with an access opening oriented in a different dimension (parallel to conduit port entry direction) than conventional designs. This dimensional reorientation allows wiremen to access wiring from the same direction as conduit approach, eliminating the need to work around orthogonal openings and significantly improving ease of wiring operations for remotely located devices
2Productivity
If additional ports and wiring chambers are added to improve wiring access, then wiring efficiency improves, but device complexity increases
Solution Approach 1:
The conduit body is segmented into distinct functional zones: a passage for conduit connection and a separate wiring chamber for wiring operations. This segmentation allows the wiring chamber with its access opening to be added as a functional module that improves wiring efficiency without fundamentally redesigning the entire conduit body structure, thus limiting the increase in device complexity
Solution Approach 2:
The wiring chamber serves multiple functions: it provides a protected space for wiring connections, offers improved access orientation for wiremen, and can accommodate additional ports for enhanced connectivity. This multi-functionality justifies the added structural complexity by delivering multiple benefits from a single design feature
