Flex-Fitting Cable Tray Segmented Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cable tray systems lack flexibility to accommodate diverse installation requirements, particularly in transitioning between straight and curved sections, limiting their adaptability in various settings.
Innovation Solution
A cable tray system comprising two or more rigid sections coupled by flexible wires, such as U-shaped, loop-shaped, or V/W-shaped flex-wires, which allow the sections to move relative to each other when tension is applied, and a removable fastening device to lock them into a rigid position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid cable tray sections are used to maintain structural integrity, then strength and stability are improved, but flexibility and adaptability to different installation configurations deteriorate
Solution Approach 1:
The cable tray system is divided into multiple rigid sections that can be independently positioned and connected. Each section maintains its structural integrity while the segmented design allows the overall system to be configured in different arrangements to accommodate various installation requirements.
Solution Approach 2:
The cable tray system transitions from a static rigid structure to a dynamic configurable system. Rigid sections are connected through movable joints that allow adjustment of angles and positions, enabling the tray to adapt to different installation configurations while maintaining structural strength in each section.
2Stability of the object's composition
If rigid cable tray sections are connected to maintain structural stability, then stability is improved, but ease of installation and reconfiguration deteriorates
Solution Approach 1:
The cable tray is segmented into standardized rigid sections with consistent connection interfaces. This segmentation allows for pre-fabrication of stable sections that can be easily assembled and reconfigured during installation without compromising overall stability.
Solution Approach 2:
The connection parameters between rigid sections are designed to be adjustable within certain ranges, allowing installers to modify angles and positions while maintaining stable connections. This parameter adjustability facilitates ease of installation and reconfiguration without sacrificing structural stability.
3Strength
If fixed connections are used between cable tray sections to ensure structural integrity, then strength is improved, but adaptability to different configurations deteriorates
Solution Approach 1:
The connection system incorporates dynamic elements that allow rigid sections to be securely connected at variable angles and positions. The connections maintain structural integrity when assembled while enabling reconfiguration through adjustable mounting mechanisms that preserve strength across different configurations.

AI summary
A cable tray system including two or more cable tray sections comprising a first side rail and a second side rail arranged substantially parallel to one another and a floor extending between. The tray system also includes one or more flex-wires for joining the cable tray sections, where the flex-wires can be U- or loop-shaped. Upon exerting tension on the flex-wires, the first and second cable tray sections can move away from one another from a first position to a second position. In addition, the tray system includes a fastening device that removably locks the tray system into the second position.
