Cable Arm Slide Connection for Two-Sided Rack Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection devices for cable management arms and slide assemblies restrict the width and space due to protruding components, making it difficult to remove the cable support arm from the rails, especially when the chassis needs to be removed from a storage position, as they only allow for one-directional removal.
Innovation Solution
A connection device with a connection member featuring bent portions, a sidewall with a window, and an engaging member with a resilient arm and insertion piece, allowing for two-sided operation by using insertion arms and a resilient arm to maintain and release the connection between the cable management arm and the slide assembly, reducing protrusion and enhancing space efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plungers are used to connect the cable support arm to the rails, then the connection can be made, but the plungers protrude beyond the chassis and restrict the width and space when the chassis is installed in the rack
Solution Approach 1:
The engaging member is nested within the connection member, with the resilient arm and engaging portion contained inside the hollow body structure. This nesting arrangement allows the connection mechanism to be compact and not protrude beyond the chassis, resolving the space restriction problem while maintaining connection functionality
Solution Approach 2:
Instead of using protruding plungers that extend outward, the invention inverts the design by creating a recessed engaging member within the connection member. The engaging portion is contained within the hollow body, turning the conventional protruding connection into a recessed one, thereby eliminating the width restriction issue
2Reliability
If plungers are used for connection, then the connection can be made, but when the cable support arm is removed from the rails, the plungers provide only one removal direction, making it difficult to pull the plungers to release the connection when the chassis is to be removed from the rack from the storage position
Solution Approach 1:
The connection member is segmented into multiple functional parts: the hollow body, the resilient arm, the engaging portion, and the button. This segmentation allows the engaging mechanism to be actuated from different sides independently, enabling removal from either the front or rear of the chassis without interference, thus improving operational ease
Solution Approach 2:
The invention inverts the conventional single-direction plunger design by creating a bidirectional engagement system. The engaging portion can be actuated from either side of the chassis through the resilient arm mechanism, allowing removal operations to be performed from both front and rear, thereby resolving the directional limitation

Function Achieved in This Case
Enables convenient two-sided operation for releasing the connection between the cable management arm and the slide assembly, reducing space occupation and facilitating easier installation and removal, while maintaining secure positioning.
Implementation Method 1
an engaging member fixed to the sidewall of the connection member and having a resilient arm and an engaging portion, wherein the resilient arm extends to the window of the connection member

AI summary
A connection device for a cable management arm and a slide assembly includes a connection member, an engaging member and an insertion piece. The connection member is fixedly connected to the cable management arm and includes a passage and a window. The engaging member is fixedly connected to the connection member and has a resilient arm and an engaging portion. The resilient arm is located corresponding to the window. The insertion piece is fixedly connected to the slide assembly and has two insertion arms. One of the insertion arms has a contact section located corresponding to the engaging portion. When the insertion piece is inserted into the passage, the engaging portion of the engaging member contacts the contact section of the insertion arm to position the insertion piece to the connection member.
