Monolithic Conduit Outlet Body with Varying Hub Dimensions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conduit outlet bodies often require the use of threaded reducers to adjust the cross-sectional dimensions of axial hub openings, leading to potential corrosion and water ingress issues, especially in applications like stanchion light mounting where smaller diameters are needed.
Innovation Solution
A conduit outlet body with integrally formed axial and transverse hubs of varying cross-sectional dimensions, eliminating the need for threaded reducers by configuring the hubs to directly accommodate different conduit sizes, such as ¾ in and 1 in Metric Trade Sizes, and incorporating a monolithic design with access windows for easy access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If threaded reducers are used to adjust the cross-sectional dimensions of axial hub openings, then different conduit sizes can be accommodated, but corrosion and water ingress issues occur
Solution Approach 1:
The patent integrates multiple hub openings with different cross-sectional dimensions directly into the conduit outlet body as a single monolithic structure. This eliminates the need for separate threaded reducer components by incorporating varying opening sizes (e.g., ¾ inch and 1 inch Metric Trade Sizes) directly into the body, thereby maintaining adaptability while removing the corrosion-prone threaded interfaces that could allow water ingress.
Solution Approach 2:
The conduit outlet body is designed to perform multiple functions simultaneously: it provides structural support, creates multiple access points for different conduit sizes, and serves as a junction point for internal wiring. The monolithic structure with varied hub openings universalizes the component to handle different conduit configurations without requiring additional adapters or reducers.
2Adaptability or versatility
If threaded reducers are used to adjust hub opening dimensions, then conduit size adaptability is achieved, but device complexity increases
Solution Approach 1:
Multiple functional elements (hubs with different opening sizes) are merged into a single conduit outlet body component. This consolidation eliminates the need for separate threaded reducer parts, directly reducing device complexity while maintaining the ability to accommodate various conduit sizes through the integrally formed hubs.
Solution Approach 2:
The conduit outlet body is designed as a universal component that incorporates multiple hub openings of different cross-sectional dimensions, allowing it to serve multiple conduit connection functions simultaneously. This multi-functionality eliminates the need for multiple specialized components, thereby simplifying the overall device structure.
3Reliability
If monolithic design with varying hub opening dimensions is used, then threaded reducers are eliminated, but manufacturing complexity increases
Solution Approach 1:
The patent combines multiple hub openings with different cross-sectional dimensions into a single monolithic conduit body that can be manufactured as one integrated piece. This approach eliminates the need for separate threaded reducer components, improving reliability by removing potential corrosion and water ingress points, while the monolithic structure allows for streamlined manufacturing processes.

AI summary
A conduit outlet body includes a body conduit, an axial hub, a transverse hub, and an access window that are integrally and monolithically formed as a single, one-piece component. The cross-sectional dimension of the transverse hub opening is different than the cross-sectional dimension of the axial hub opening.
