Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for mounting and dismounting disk drives in servers are inefficient, requiring the use of tools and screws, which prolongs the process and increases maintenance time and production costs.
Innovation Solution
A server disk drive holder assembly comprising an outer tray, an inner tray, and a latch arm with a hook portion and a flexible restoring element, allowing for tool-free mounting and dismounting by engaging and disengaging the trays without screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional screw fixing method is used to secure disk drive on tray, then the disk drive is firmly fixed, but the mounting and dismounting process becomes time-consuming and requires tools
Solution Approach 1:
The tray is divided into an outer tray and an inner tray that can be independently assembled and disassembled. The inner tray can be quickly inserted into and removed from the outer tray without requiring disassembly of the entire structure, enabling rapid maintenance while maintaining secure fixation during operation.
Solution Approach 2:
A latch arm with a hook portion serves as an intermediary mechanism between the inner tray and outer tray. The hook portion engages with a locking hole to provide secure fixation, while the entire latch arm can be quickly actuated to release the connection, enabling tool-free mounting and dismounting.
2Reliability
If multiple screws are used to fix disk drive, then the fixation is secure, but the complexity of the fixing structure increases
Solution Approach 1:
Multiple fixing functions are merged into a single integrated latch mechanism. The latch arm combines the locking hook, the release mechanism, and the structural connection into one component, eliminating the need for multiple separate screws and fasteners while maintaining secure fixation.
Solution Approach 2:
The latch arm serves multiple functions: it provides the locking mechanism, acts as a structural support, and serves as the release mechanism. This multi-functional design reduces the overall number of components needed in the fixing structure, simplifying the assembly while maintaining reliability.
3Productivity
If tool-free mounting is implemented, then maintenance efficiency improves, but the locking mechanism becomes more complex
Solution Approach 1:
The latch arm is designed as a movable component that can be easily actuated between locked and unlocked positions. The dynamic nature of the latch arm allows for quick engagement and disengagement of the inner tray, achieving tool-free mounting while keeping the locking mechanism relatively simple through mechanical advantage.
Solution Approach 2:
The latch mechanism is designed to be self-actuating through a simple pulling motion on the latch arm. The flexible restoring element and hook portion work together to automatically engage and disengage the locking mechanism without requiring external tools, maintaining simplicity while enabling tool-free operation.

AI summary
A server disk drive holder assembly includes an outer tray, an inner tray and a latch arm. The outer tray includes a locking hole. The inner tray overlaps on the outer tray. The inner tray is movable with respect to the outer tray. The inner tray includes a fastening hole. A latch arm is pivotally disposed on an outer side of the outer tray. The latch arm includes a hook portion. When the locking hole is aligned with the fastening hole, the hook portion is inserted through the locking hole to be engaged with the fastening hole. A disk drive can be clamped between the outer tray and the inner tray. By utilizing the movable latch arm to fasten the outer tray and the inner tray, the disk drive can be quickly mounted and dismounted.
