Bladed Chassis Front Rear Blade Access and Cable Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bladed chassis systems lack flexibility in blade insertion and removal, with limited access to optical adapters and inefficient cable management, particularly in terms of directional flexibility and secure cable routing.
Innovation Solution
A bladed chassis system that allows blades to be inserted and removed from both the front and rear, featuring a chassis with open portions, guide members, and a latching arrangement that enables secure locking and unlocking of blades, along with a cable management system that routes optical fibers efficiently while maintaining a minimum bend radius.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If blades are fixed to be inserted only from the front, then the chassis structure is simple, but the flexibility and accessibility of the system is reduced
Solution Approach 1:
The chassis is segmented into front and rear portions, each with independent access capabilities. The rear portion can be opened separately from the front, allowing blade insertion and removal from either end without requiring the entire chassis to be accessed from one direction only.
Solution Approach 2:
The chassis is designed with universal access capability, allowing blades to be inserted and removed from both front and rear directions. This multi-functional design enables the same chassis structure to accommodate different operational scenarios and user preferences.
2Ease of operation
If optical adapters are mounted on blades that remain fixed in the chassis, then the mounting structure is simple, but access to optical adapters is limited
Solution Approach 1:
The blade system transitions from a static fixed position to a dynamic movable position. Blades can be extended forward from the chassis to provide enhanced access to optical adapters, and the latching mechanism allows for controlled movement between retracted and extended states.
Solution Approach 2:
A latching mechanism acts as an intermediary between the blade and chassis, enabling controlled movement. The latch allows the blade to be securely held in either the retracted or extended position, facilitating easy access to optical adapters when needed while maintaining structural integrity.
3Adaptability or versatility
If cable clamps are fixed to the rear of the chassis, then cable routing is simple, but cable management flexibility is reduced
Solution Approach 1:
The cable management system incorporates movable cable clamps that can be adjusted along the rear portion of the chassis. This dynamic positioning capability allows cables to be routed flexibly to accommodate different blade positions and cable entry points while maintaining secure cable management.

AI summary
A bladed chassis system facilitates installation of the bladed chassis system and replacement of the blades at the chassis. Blades can be inserted and removed from the front and/or the rear of the bladed chassis system at the discretion of the user. Blades can be moved between discrete positions. In examples, blades can be one-handedly released from the chassis to allow movement between discrete positions. In examples, accidental movement past a discrete position is inhibited. Accidental removal of the blades from the chassis is inhibited. The chassis and blades cooperate to manage the optical fiber cables routed through a cable port in the chassis to the blades.
