Modular Conduit Body Segmentation for Flexible Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical conduit systems lack flexibility and ease of reconfiguration, leading to complexities in ordering, stocking, and installation due to fixed configurations.
Innovation Solution
The conduit body design allows for configurations such as 'go-forward', 'T', 'turn-left', and 'turn-right' setups, with interchangeable housing, hub, and cover plate components that can be secured and sealed using screws and O-rings, enabling easy reconfiguration between these and other configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fixed-configuration conduit bodies are used, then manufacturing and installation are straightforward, but flexibility and adaptability are reduced
Solution Approach 1:
The conduit body is divided into separate modular components including a body portion, hub portion, cover plate, and seal member. Each component can be independently manufactured and then assembled in different configurations (go-forward, T, turn-left, turn-right) to provide multiple conduit routing options from a single set of components.
Solution Approach 2:
A single universal body portion design can accommodate multiple conduit configurations through interchangeable hub and cover plate assemblies. The standardized interface allows the same body to serve multiple functions across different installation scenarios, eliminating the need for multiple specialized conduit body types.
2Adaptability or versatility
If multiple fixed-configuration conduit bodies are stocked for different routing needs, then adaptability is improved, but ordering and inventory complexity increase
Solution Approach 1:
The universal body portion with standardized interfaces allows a single inventory item to replace multiple configuration-specific conduit bodies. Contractors can stock fewer universal bodies and create different configurations as needed, simplifying ordering and inventory management while maintaining adaptability.
Solution Approach 2:
By segmenting the conduit body into standardized modular components, each component can be independently stocked and then combined in various configurations. This reduces the total number of unique parts needed in inventory compared to stocking complete pre-configured conduit bodies for every possible routing scenario.
3Ease of operation
If conventional conduit bodies are installed, then installation is straightforward, but reconfiguration capability is lost
Solution Approach 1:
The modular segmented design with standardized interfaces allows conduit bodies to be easily disassembled into individual components and reassembled in different configurations. This maintains installation simplicity while enabling future reconfiguration without requiring specialized tools or procedures.
Solution Approach 2:
The conduit body system transitions from a fixed static configuration to a dynamic reconfigurable system. The standardized threaded interfaces and modular components enable the installation to be adapted and reconfigured as project needs change, providing long-term flexibility.

AI summary
A conduit body may include a body including a side and a bottom to form a cavity. The side of the body may include an outer surface and a recessed surface forming grooves. The conduit body may include a hub that includes an annular tube forming an opening to receive a cable. The body may be configured to receive the edges of the hub in the grooves such that movement of the hub in a linear direction may move the hub through the grooves to couple the hub to the body. When the hub is coupled to the body using the grooves, the conduit body may be configured to receive the cable through the annular tube of the hub and through the opening in the recessed surface into the cavity.
