Cable Management Arm Locking Mechanism for Secure Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable arrangement devices for cable management arms often result in cables being easily shifted or dropped from support features due to their design, leading to instability and inconvenience during positioning or removal.
Innovation Solution
A cable arrangement device featuring a support member with a U-shaped body and a locking member that pivots to allow upright positioning, enabling easy installation and removal of cables by engaging and disengaging the hook portions and inclined surfaces, preventing the locking member from impeding cable placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cable support features are designed as hook-like members with open top, then the cables can be quickly positioned, but the cables may drop from the open top when the arm is pulled or bent
Solution Approach 1:
The locking member is designed to pivot between a locked position (where it engages with the hook portion to secure cables) and an unlocked position (where it allows cable installation/removal). This dynamic positioning resolves the contradiction by providing both quick access and secure retention based on operational state
Solution Approach 2:
The locking member acts as an intermediary between the hook portion and the cables. When engaged, it prevents cable drop while maintaining the open-top hook structure for easy cable positioning. The locking member mediates between the need for quick positioning and the need for secure retention
2Reliability
If the locking member is engaged with the hook portion, then the cables are securely held, but the locking member may impede cable placement during installation
Solution Approach 1:
The locking member pivots to an unlocked position during cable installation to clear the path for cable placement, then rotates to the locked position to secure the cables. This dynamic movement resolves the contradiction by temporarily removing the locking member from the cable path during installation while providing secure retention during operation
Solution Approach 2:
The locking member is designed to be movable to an unlocked position before cable installation occurs. This preliminary action of moving the locking member out of the way allows smooth cable placement, and subsequent rotation locks the cables in place

AI summary
A cable arrangement device for a cable management arm includes a support member (14) and a locking member (16). The support member (14) includes a fixing portion (18), an accommodation portion (20) and a hook portion (22). The accommodation portion (20) includes a first sidewall (24), a second sidewall (26) and a bottom wall (28) connected between the first and second sidewalls (24, 26). The first sidewall (24) is fixed to the fixing portion (18) and has a connection member (30) which has a first pivotal portion (32) which has a positioning feature (34). The second sidewall (26) is fixed to the hook portion (22). The locking member (16) has a second pivotal portion (36) and an engaging portion (38). The second pivotal portion (36) is pivotably connected to the first pivotal portion (32) and has an engaging feature (40) engaged with the positioning feature (34). The engaging portion (38) is engaged with the hook portion (22) of the first sidewall (14) when the engaging portion (38) is in locked position.
