Conduit Coupling Adapter for Stable Junction Box Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for securing wiring conduits to junction boxes, such as handholes, fail to prevent conduit shifting during installation tasks and restrict cable routing due to excess conduit, necessitating larger enclosures or additional boxes.
Innovation Solution
A conduit coupling adapter with a first end for adhesive attachment to the conduit and a second end with threads for secure insertion into an enclosure, using a locking nut and washer to create a stable and watertight connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If excess conduit is inserted into the handhole to prevent unintentional extraction, then the conduit is secured against environmental conditions, but the conduit shifts during installation tasks and restricts cable routing
Solution Approach 1:
The conduit system is segmented into two functional parts: the conduit itself and the coupling adapter. The adapter is further divided into a securement portion (with teeth for gripping the conduit) and a mounting portion (with threads for the enclosure). This segmentation allows the conduit to be securely held without requiring excess length inside the enclosure, enabling efficient cable routing.
Solution Approach 2:
The coupling adapter serves as an intermediary component between the conduit and the enclosure. Instead of directly inserting excess conduit into the enclosure, the adapter mediates the connection by providing a securement mechanism (teeth that grip the conduit) and a mounting mechanism (threads that engage the enclosure), eliminating the need for excess conduit while preventing both extraction and shifting.
2Reliability
If excess conduit is inserted into the handhole to prevent unintentional extraction, then the conduit remains secure environmentally, but a larger junction box or additional boxes are needed to accommodate the extra conduit
Solution Approach 1:
The coupling adapter segments the connection function into a securement portion that grips the conduit externally and a mounting portion that engages the enclosure. This allows the conduit to be securely attached without requiring significant internal volume of the enclosure, maintaining compact enclosure size while ensuring reliable conduit security.
Solution Approach 2:
The adapter acts as an intermediary that enables secure conduit attachment without requiring the conduit to extend into the enclosure volume. The securement portion with teeth grips the conduit outside the enclosure, while the mounting portion with threads engages the enclosure wall, eliminating the need for additional enclosure volume to accommodate excess conduit.
3Ease of operation
If the conduit is not securely attached, then cable routing and installation tasks are easier, but the conduit shifts during these tasks
Solution Approach 1:
The coupling adapter provides dynamic adaptability during installation. The securement portion with teeth can grip the conduit at various positions, allowing the installer to accommodate slight variations in conduit insertion depth or angle. Once installed, the teeth firmly grip the conduit to prevent shifting, providing both installation flexibility and operational stability.
