Movable Cable Holder for Server Rack Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In densely packed server racks, the fixed positioning of cables in front of slots hinders unit insertion and removal, as cables sag and interfere with other components, complicating maintenance and increasing space requirements.
Innovation Solution
The implementation of a cable holder system with sliders and rails that allows the cable holder to slide transversely, guided by upper and lower rails, preventing cable sagging and obstruction during unit insertion or removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cables are fixed at the space in front of slots, then cable management is simplified, but unit insertion and removal becomes difficult
Solution Approach 1:
The cable guide is designed to be movable rather than fixed, allowing it to be shifted to the side during unit insertion/removal and returned to its original position afterward. This dynamic positioning resolves the contradiction by providing fixed cable management during normal operation while enabling easy unit access during maintenance.
Solution Approach 2:
The cable guide is prepared in advance with a movable structure that can be quickly repositioned. Before unit insertion or removal, the cable guide is preliminarily shifted to the side, clearing the path for unit access. This preliminary action enables both good cable management and easy unit maintenance.
2Ease of operation
If a movable cable guide is provided to enable unit insertion and removal, then maintenance workability improves, but the structure becomes more complex
Solution Approach 1:
The cable guide is segmented into a movable portion and a fixed portion, allowing only the necessary part to move while the rest remains stationary. This reduces the complexity of the movable structure while still achieving the goal of improving maintenance workability.
Solution Approach 2:
Only the specific portion of the cable guide that interferes with unit insertion is made movable, while other portions remain fixed. This localized mobility minimizes structural complexity while maximizing maintenance accessibility.
3Ease of operation
If cables are pulled out or given long extra lengths to move the cable guide, then unit access is improved, but cables sag and interfere with other components
Solution Approach 1:
The cable guide is extracted from its fixed position and made independently movable. This allows the cable guide to be repositioned without moving the cables themselves, preventing cable sagging and interference while still improving unit access.
Solution Approach 2:
The movable cable guide acts as an intermediary between the cables and the unit insertion path. By moving this intermediary component rather than the cables themselves, unit access is improved without causing cable sagging or interference with other components.

AI summary
An information processing apparatus includes a rack in which slots into each of which an assembly is removably inserted are arranged in a top-bottom direction, a cable holder that bundles cables removably attached to the assembly, using a holding portion extending in the top-bottom direction, a pair of sliders fixed to an upper part and a lower part of the cable holder, and a pair of upper and lower rails fixed to the rack and guiding the pair of sliders to slide the cable holder in a transverse direction on an opening side of the slots.
