Rack Cable Management Arm with Blocking Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable management solutions for rack systems do not effectively limit the movement of cable management arms to a specific range, failing to meet market requirements for precise positioning and stability during the insertion and removal of electronic devices.
Innovation Solution
A cable management device with a first and second cable management arm, a first connecting member, and a blocking member that limits the relative movement between the connecting member and the cable management arm to a specific range, using a pivotally connected shaft member and limiting parts to prevent excessive movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cable management arms are made movable to accommodate device insertion and removal, then adaptability is improved, but movement control and positioning precision deteriorate
Solution Approach 1:
The cable management arm employs a dynamic structure with pivot connections at multiple points (first pivot connection between connecting member and arm, second pivot connection between arm and cable management device). This allows the arm to adapt its position dynamically during device insertion/removal while the blocking member provides precise positioning limits to prevent excessive movement.
Solution Approach 2:
The blocking member changes the movement parameter of the cable management arm by physically limiting its rotation range. The blocking member abuts against the arm or connecting member to prevent rotation beyond predetermined angles, thereby controlling the movement parameter within acceptable bounds while maintaining adaptability.
2Adaptability or versatility
If cable management arms are made movable to accommodate device insertion and removal, then adaptability is improved, but structural stability deteriorates
Solution Approach 1:
The system uses dynamic pivot connections that allow controlled movement during device insertion/removal operations. The blocking member provides stable positioning limits, ensuring the arm returns to predetermined positions, thereby maintaining structural stability while enabling necessary adaptability.
Solution Approach 2:
The blocking member provides preliminary anti-action by preemptively preventing the cable management arm from rotating beyond safe angular limits. This counteracts potential instability by establishing hard boundaries on movement, ensuring the arm remains within stable operational ranges throughout the device insertion and removal process.
3Measurement precision
If blocking members are added to limit arm movement, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The cable management device is segmented into distinct functional components: the cable management arm, the connecting member, and the blocking member. This segmentation allows the blocking member to be designed as a simple, dedicated element for positioning control, minimizing its complexity while achieving precise positioning functionality.
Solution Approach 2:
The blocking member acts as an intermediary element between the cable management arm and the external environment. It provides precise positioning control through simple geometric blocking rather than complex active control mechanisms, thereby improving positioning precision without significantly increasing overall device complexity.

AI summary
A cable management device (38) includes a first cable management arm (40), a second cable management arm (42), a connecting member (62) and a blocking member (75). The second cable management arm (42) is movable relative to the first cable management arm (40). The connecting member (62) is movably connected to the first cable management arm (40). The blocking member (75) is arranged adjacent to a junction area between the connecting member (62) and the first cable management arm (40), and configured to abut against at least one of the connecting member (62) and the first cable management arm (40) to limit a relative movement between the connecting member (62) and the first cable management arm (40) to a limited range.
