Pre-jointed Cable Tray with Movable Fishplates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cable tray systems require separate storage and assembly of fishplates and cable tray sections, leading to increased assembly time, logistical difficulties due to non-standard lengths, and inefficient storage management.
Innovation Solution
A pre-jointed cable tray device with temporarily mounted fishplates that are immobilized by braking and elastic locking means, allowing for standard length storage and delivery without protruding, enabling easy handling and assembly by integrating fishplates into the cable tray sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If fishplates are permanently mounted on cable tray sections at their final positions, then assembly time is reduced and management is simplified, but the total length of the cable tray increases and logistical handling becomes difficult
Solution Approach 1:
The fishplates are designed with movable mounting that allows them to be positioned in different locations along the cable tray section. During storage and transport, they are positioned at the end to maintain standard length, and during assembly, they can be moved to the appropriate joining positions. This dynamic repositioning capability resolves the contradiction between reduced assembly time and maintained standard length.
Solution Approach 2:
The cable tray system is segmented into modular sections with fishplates that can be independently positioned and mounted at different locations. This segmentation allows the fishplates to be stored with the cable tray sections in a compact configuration while enabling flexible positioning during assembly to achieve the desired connection points without permanently extending the overall length.
2Volume of stationary object
If fishplates and cable tray sections are stored and delivered separately, then storage volume is optimized, but assembly time increases and management becomes complex
Solution Approach 1:
The fishplates are permanently mounted on the cable tray sections during manufacturing, merging two previously separate components into a single integrated unit. This combination reduces assembly time on-site as everything is pre-assembled, while the modular design ensures that the overall storage volume does not increase significantly compared to separate storage of components.
3Ease of operation
If fishplates are mounted at the end of cable tray sections, then they are ready for assembly, but they protrude and increase the total length causing logistical difficulties
Solution Approach 1:
The fishplates are designed with movable mounting that allows them to be positioned in different locations along the cable tray section. During storage and transport, they are positioned at the end to maintain standard length, and during assembly, they can be moved to the appropriate joining positions. This dynamic repositioning capability resolves the contradiction between reduced assembly time and maintained standard length.

AI summary
The invention relates to a cable tray device (1) comprising a cable tray section (2A) extending along a longitudinal axis (X2A), which has a bottom (8) delimited between two walls (6), these walls having an end part which delimits a first free edge, two splices (4) for connecting the cable tray section with another cable tray section (2B), each of which comprises a first branch adapted to be arranged against a wall of the cable tray section and a second branch adapted to be arranged against the bottom of the cable tray section, the first branch of the splices having an end part which delimits a second free edge and which is able to overlap the end part of the wall.The splices are suitable for being wedged on the cableway section in a temporary configuration where they straddle the walls and are immobilized on the cableway section by braking or locking means which oppose the movement (F4) of the splices in axial translation along the cableway section, and elastic locking means which oppose the tilting (F2) of the splices around the walls of the cableway section.
