Universal Joiner for Channel Raceway Configurations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing joiners for channel raceways lack flexibility and efficiency in connecting multiple pieces of channel framing to form various configurations, such as tee, elbow, and cross joiners, which limits their adaptability and stability in housing wires and cables.
Innovation Solution
A joiner system comprising a base with upward posts and connecting projections that can form different configurations by attaching a joiner wall panel via snap-fit connections, allowing for interconnection of two, three, or four pieces of channel framing to create a channel raceway assembly, with optional frangible connections for further configuration options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing joiners are used to connect channel framing pieces, then basic connection function is achieved, but flexibility and adaptability for various configurations (tee, elbow, cross joiners) are limited
Solution Approach 1:
The joiner body is designed with multiple connecting projections that can accommodate different channel framing configurations (tee, elbow, cross joiners) using a single universal design. The base with multiple posts and connecting projections allows the same joiner body to serve multiple functions by simply changing the arrangement of channel pieces rather than requiring different specialized joiners for each configuration type.
Solution Approach 2:
The joiner is divided into separable components including a base, multiple posts, and connecting projections that can independently connect to different channel framing pieces. This segmentation allows flexible assembly and disassembly for various configurations while maintaining structural integrity through standardized connection interfaces.
2Productivity
If traditional connection methods are used for channel framing, then structural stability may be achieved, but connection efficiency and ease of assembly are reduced
Solution Approach 1:
Multiple connection functions are merged into a single joiner body that simultaneously connects multiple channel framing pieces through its base and connecting projections. This consolidation allows all connections to be made in one assembly operation rather than requiring separate connection steps for each channel piece, thereby improving both productivity and ease of operation.
Solution Approach 2:
The connecting projections are designed to automatically align and engage with the channel framing pieces through a snap-fit or self-locking mechanism. This self-aligning feature eliminates the need for precise manual positioning and complex fastening procedures, making assembly easier and more efficient while ensuring consistent structural stability.
3Adaptability or versatility
If channel framing pieces are connected to form various configurations, then adaptability is improved, but connection stability and structural strength may be compromised
Solution Approach 1:
The connecting projections are designed with asymmetric geometries that provide different connection characteristics for different channel framing configurations. Each projection can be optimized for specific connection types (tee, elbow, cross) while maintaining overall structural stability. The asymmetric design ensures proper orientation and secure engagement for each configuration type.
Solution Approach 2:
The connecting projections incorporate curved or rounded surfaces that facilitate smooth engagement and distribution of mechanical stresses across the connection interface. This curvature allows for slight adjustments in alignment while maintaining stable connections across various configurations, thereby preserving both adaptability and reliability.

AI summary
A joiner system for a channel raceway includes a joiner body with first and second posts, and a joiner wall panel separate from the joiner body. The joiner wall panel connects to the joiner body between the first and second posts to form a wall between the first and second posts. First and second connecting projections extend outward from adjacent the respective first and second posts. The first and second connecting projections are spaced apart from one another and in generally opposing relationship with respect to one another. The joiner body has a snap-fit component on the lower side of a base of the joiner body. The snap-fit component mates in a snap-fit connection with a splice plate to interconnect the joiner body and at least two pieces of channel framing.
