Drive Cage Hinge Latch for Tool-Free Peripheral Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for mounting and removing internal peripheral devices from a drive cage assembly in servers or personal computers are time-consuming and can lead to electrical shorts due to loose screws, and require additional support during transport.
Innovation Solution
A latch system with a hinge bracket that allows for either rack or tower orientation, enabling secure attachment and detachment of peripheral devices without tools, using a combination of pivotally connected latches and guide slots for easy operation and support, eliminating the need for additional fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws or fastening devices are used to mount peripheral devices, then the devices can be securely fixed, but the removal and installation process becomes time-consuming and risks electrical shorts from misplaced screws
Solution Approach 1:
The patent replaces the traditional screw-based mechanical fastening system with a spring-loaded latch mechanism. The latch system uses elastic springs to provide locking force, eliminating the need for screws and manual fastening operations. Users simply slide the peripheral device into the drive cage, and the spring-loaded latches automatically engage to secure it, dramatically reducing installation time while maintaining secure mounting.
2Object-affected harmful factors
If plastic clips are used to lock peripheral devices, then screw misplacement is avoided, but additional metal brackets or locking screws are needed for transport support
Solution Approach 1:
The patent combines multiple functions into a single integrated latch system. The spring-loaded latches simultaneously provide secure locking during operation and adequate support during transport, eliminating the need for separate metal brackets or additional locking mechanisms. The unified design maintains device security while avoiding the complexity of multiple components.
3Adaptability or versatility
If multiple fastening methods are provided for different orientations, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent employs a dynamic hinge bracket that can pivot between different orientations to accommodate both rack mode (vertical) and tower mode (horizontal) configurations. This single movable component replaces the need for separate latch systems for each orientation, maintaining versatility while reducing overall device complexity through dynamic adaptability.

AI summary
Latch systems for a drive cage assembly are disclosed. In an exemplary embodiment, the latch system may be operated by moving a hinge bracket in a first direction to slide at least one latch on the hinge bracket into an open position. Then receiving a peripheral device in the drive cage assembly in either a tower orientation or a rack orientation when the at least one latch is in the open position. Then moving the hinge bracket in a second direction to slide the at least one latch into a closed position and secure the peripheral device in the drive cage assembly.
