Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing server racks lack efficient mechanisms for securely locking and conveniently unlocking server nodes for maintenance and replacement, while optimizing space utilization and ensuring adequate clearance for maintenance access.
Innovation Solution
A computing device rack with a retaining member and actuator system that allows the latch to move between initial and final positions, engaging or disengaging with the server node for locking or unlocking, using resilient materials and actuators to deform the link portion and facilitate secure attachment or removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is provided to securely lock each server node to the rack, then reliability of server node retention is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is divided into modular components: a retaining member with latch, a separate actuator, and mounting features. Each component performs a specific function, allowing independent optimization and simplifying manufacturing while maintaining overall reliability through coordinated operation of these segmented parts.
Solution Approach 2:
The resilient retaining member automatically engages with the server node upon insertion and locks into place without requiring manual intervention. The mechanism self-actuates through the resilient deformation of the retaining member, eliminating the need for complex control systems while ensuring reliable retention.
2Reliability
If manual locking and unlocking procedures are implemented, then reliability of server node retention is improved, but ease of operation deteriorates
Solution Approach 1:
The manual mechanical locking operation is replaced by an actuator-driven system that automatically moves the retaining member between locked and unlocked states. This substitution eliminates tedious manual manipulation while maintaining secure retention through the actuator-controlled resilient engaging structure.
Solution Approach 2:
The retaining member transitions dynamically between locked and unlocked states through actuator operation, enabling quick server node installation and removal. The resilient nature of the retaining member allows for smooth, controlled movement between positions, improving operational speed and convenience while maintaining reliability during transitions.
3Reliability
If server nodes are securely locked to the rack, then reliability of system operation is improved, but ease of repair deteriorates
Solution Approach 1:
The retaining member is designed to be dynamically controllable, transitioning between a locked state that secures the server node during operation and an unlocked state that facilitates easy removal for maintenance. The actuator enables rapid state changes, allowing the system to switch between reliable retention and ease of repair as needed.
Solution Approach 2:
The locking mechanism temporarily holds the server node in a secured state during normal operation, then readily releases it when maintenance is required. The resilient retaining member can be quickly reset to its initial position after release, allowing the same mechanism to serve both retention and repair facilitation functions without permanent modification.
4Ease of repair
If more clearance space is provided around the rack for maintenance access, then ease of repair is improved, but volume of the computing system increases
Solution Approach 1:
The locking and unlocking functions are extracted from manual operations and integrated directly into the rack structure through the actuator-retaining member system. This extraction eliminates the need for excessive clearance space that would otherwise be required for manual manipulation of locking mechanisms, allowing compact rack design while maintaining ease of repair through automated operation.

Implementation Method 1
Movement of the actuator relative to the frame and the retaining member from a first position to a second position deforms the retaining member to move the latch from an initial position to a final position relative to the frame

AI summary
A computing device rack for housing a computing device. The rack comprises a frame to which a computing device is mountable, a retaining member mounted to the frame, and the retaining member having a latch that is movable relative to the frame, and an actuator movably coupled to the frame and the retaining member. Movement of the actuator relative to the frame and the retaining member from a first position to a second position deforms the retaining member to move the latch from an initial position to a final position relative to the frame, and thereby engages or disengages with the computing device that is mounted on the frame for locking or unlocking, respectively.
