Telescoping Wire Cable Tray for Cut-Free Length Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire cable tray systems require cutting and deburring during installation, which is time-consuming and poses safety risks due to sharp cut ends, and lack adjustable length capabilities without modification.
Innovation Solution
A telescoping wire cable tray system comprising outer and inner wire cable trays with transverse and longitudinal wires that slide relative to each other, secured by a trapeze support device with locking clips, allowing adjustable length without cutting, and incorporating a bend radius fitting that maximizes cable routing space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cable trays are cut to fit during installation, then the cable trays can be customized to various lengths, but the installation process becomes time-consuming and creates safety hazards from sharp cut ends
Solution Approach 1:
The cable tray system employs telescoping sections with movable inner trays that can slide within outer trays, allowing the overall length to be dynamically adjusted during installation without cutting. The locking clips enable the system to transition between extended and retracted states, providing customizable lengths while eliminating time-consuming cutting operations and safety hazards associated with sharp edges.
2Adaptability or versatility
If cable trays are cut to fit during installation, then the cable trays can be customized to various lengths, but the installation process becomes complex and hazardous
Solution Approach 1:
The telescoping mechanism with sliding inner trays and locking clips provides a simple, tool-free adjustment system that enhances ease of operation. Installers can easily extend or retract the cable tray sections by sliding the inner trays in or out and securing them with locking clips, eliminating the complexity and safety risks of cutting operations while maintaining full adaptability for various length requirements.
3Ease of manufacture
If fixed-length cable trays are used, then manufacturing and shipping is simplified, but the system lacks flexibility to accommodate various installation requirements
Solution Approach 1:
The cable tray system is divided into modular sections with standardized outer and inner trays that can be manufactured in fixed lengths for simplified production and shipping. These segmented modules are then combined using telescoping connections with locking clips, allowing the system to achieve various total lengths and configurations. This segmentation enables both manufacturing simplicity and installation flexibility to coexist.
4Device complexity
If traditional cable tray systems are used, then the structure is simple, but adjusting the length requires cutting and modification
Solution Approach 1:
The system maintains relatively simple structural elements (standardized wire trays, basic locking clips) while introducing dynamic adjustability through the telescoping mechanism. The inner trays slide within outer trays and are secured with simple locking clips, allowing length adjustment without complex mechanisms. This approach preserves structural simplicity while achieving full length adaptability.

AI summary
The present invention is directed to a telescoping wire cable tray system. The wire cable tray system includes an outer wire cable tray and an inner wire cable tray positioned within the outer wire cable tray. The inner wire cable tray slides or telescopes with respect to the outer wire cable tray enabling the length of the wire cable trays to be adjusted during installation of the wire cable tray system. The wire cable tray system may include trapeze support bars, clamps, side walls or downspout fittings.
