Multi-Section Cable Carrier for Long-Travel Slide Rails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable management assemblies for slide rail systems have limited extended length, making them inadequate for applications requiring increased distance between movable and stationary rails, which restricts their usability in meeting market demands.
Innovation Solution
A multi-section cable management device with pivotally connected arms, including a first set and a second set of arms, where the second set of arms are connected to the first set, and an additional arm, along with a supporting member, allowing the device to adapt to longer slide rail assemblies by moving the second rail with respect to the first rail, enabling extended length and sequential opening/closing operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a traditional two-arm cable management assembly is used, then the structure is simple, but the extended length is limited and cannot meet market demands for longer slide rail assemblies
Solution Approach 1:
The cable management device is divided into multiple arm sets (first set of arms and second set of arms) that can be sequentially deployed. Each arm set functions as an independent segment that can extend and retract separately, allowing the overall device to achieve greater extended length while maintaining manageable structural complexity through modular design
2Length of moving object
If the slide rail assembly extended length is increased, then it can meet market demands, but the cable management assembly cannot adequately support the longer distance
Solution Approach 1:
The cable management device employs dynamic multi-stage deployment where arm sets can extend and retract in sequence based on the slide rail position. This dynamic adaptation ensures that cable management capability is maintained throughout the entire extended range, with each arm set activating only when needed to support the current extension level

AI summary
A slide rail assembly (22) includes a first rail (28), a second rail (34) movable with respect to the first rail (28), and a cable management device (37). The cable management device (37) includes a first set of arms and a second set of arms connected to the first set of arms. The first set of arms include two arms (38a, 38b) that are movable with respect to each other. The second set of arms also include two arms (38c, 38d) that are movable with respect to each other. The cable management device (37) has a portion connected to the first rail (28) and is switched from a first state to a second state in response to the second rail (34) moving with respect to the first rail (28) from a first position (P1) to a second position (P2).
