Telescopic Cable Management Device for Server Chassis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable management devices in server chassis are inadequate in accommodating increased cable lengths or server configurations, as they do not provide sufficient distance range during server movement, leading to entanglement, pinching, or overstretching of cables.
Innovation Solution
A cable management device comprising a sliding rail assembly, cable management assembly, and connecting assembly, featuring pivotally connected sliding arms and a rotatably connected supporting bar, which allows for adjustable length extension and retraction to accommodate varying cable configurations, ensuring smooth movement and storage of cables within a server chassis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the server chassis is made longer to accommodate more cables or servers, then the cable management capability is improved, but the distance range of the existing cable management device becomes insufficient
Solution Approach 1:
The cable management device employs a telescopic structure with multiple sliding arms that can dynamically extend and retract. The sliding arms are connected through pivot joints and sliding rails, allowing the device to adjust its length according to the server's position during insertion or removal operations, thereby providing sufficient cable management capability for both compact and extended configurations.
Solution Approach 2:
The cable management device is divided into multiple segmented sliding arms (first sliding arm, second sliding arm, third sliding arm, fourth sliding arm) that can move independently relative to each other. This segmentation allows each arm to adjust its position to accommodate varying cable lengths and server configurations, solving the contradiction between adaptability and fixed length.
2Object-affected harmful factors
If the cable management device becomes longer during pulling process, then cable entanglement is prevented, but the device complexity increases
Solution Approach 1:
The device uses dynamic telescopic sliding arms that automatically extend when the server is pulled out and retract when the server is inserted. This dynamic adjustment prevents cable entanglement and overstretching without requiring a permanently complex structure, as the complexity is only activated when needed.
Solution Approach 2:
The sliding arms are nested within each other in a telescopic arrangement, with inner arms sliding within outer arms. This nesting allows the device to maintain a compact form when not in use while providing extended length when needed, reducing overall device complexity while preventing cable harm during server movement.

AI summary
A cable management device in a server chassis able to hold and safeguard a greatly extended range of cable lengths, and server chassis including same, comprises connecting assembly, sliding rail assembly, and cable management assembly. The sliding rail assembly includes parallel first and second sliding rails, the first sliding rail including outer, middle, and inner rails, and the second sliding rail including similar outer, middle, and inner rails. The assembly includes first to fourth sliding arms, together with a supporting bar. The first sliding arm is movably connected to the outer rail of the second sliding rail, and the fourth sliding arm is movably connected to the inner rail of the first sliding rail. One end of the supporting bar is connected to the middle rail of the first sliding rail, the other end is connected to the middle rail of the second sliding rail.
