Modular Drive Module for Server Extraction Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server configurations face challenges when replacing large-size disk drives with small-size disk drives, as the smaller drives do not fit the larger drive's size, leading to inefficiencies in drive replacement and space utilization.
Innovation Solution
A modular drive module design featuring a casing, circuit board, cover, and fixing member with engaging and pressing arms, allowing for detachable insertion and extraction of multiple small drives into a server's extraction opening, with a clamping mechanism to secure the circuit board and drives within the server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple small-size disk drives are assembled directly in the extraction opening without modularization, then the drives can be installed, but the overall size of the small drives does not fit the large drive's extraction opening and space utilization is inefficient
Solution Approach 1:
The patent divides the extraction opening into multiple slots to accommodate multiple small-size drives simultaneously. The modular drive module is segmented into a casing, cover, fixing member, and multiple drive units, allowing flexible configuration to match the extraction opening dimensions and improve space utilization.
Solution Approach 2:
The modular drive module design creates a universal interface that can accommodate different configurations of small-size drives. The standardized casing and fixing mechanism allow the same module structure to hold varying numbers and types of drives, providing adaptability across different server configurations.
2Productivity
If a modular drive module design is implemented, then drive replacement efficiency is improved and space utilization is optimized, but the device structure becomes more complex with additional components like casing, cover, and fixing member
Solution Approach 1:
The drive module is segmented into distinct functional components (casing, cover, fixing member) that can be independently manufactured and assembled. This segmentation simplifies the manufacturing process and allows for easier maintenance and replacement of individual components without affecting the entire assembly.
Solution Approach 2:
The fixing member incorporates self-latching mechanisms and positioning features that automatically secure the drives within the module when assembled. This self-service design reduces the need for complex fastening operations and specialized tools, simplifying the overall assembly process despite the modular structure.
3Reliability
If the fixing member with engaging arm and pressing arm is used to secure drives, then the drives are firmly fixed, but the mechanism for detaching requires pulling in specific directions which may complicate the operation
Solution Approach 1:
The fixing member employs dynamic arms (engaging arm and pressing arm) that can move between locked and unlocked positions. The arms are designed to flex and engage with corresponding features on the drives, providing secure fixation during operation while allowing controlled release when detachment is required.
Solution Approach 2:
The detachment mechanism works by reversing the engagement action - pulling the pressing arm in the opposite direction of the pressing force releases the lock. This inversion principle allows the same mechanical structure to provide both secure fixation and controlled release, maintaining reliability while enabling ease of operation.

AI summary
A drive module is inserted into an extraction opening of a server and includes a casing, a circuit board, a fixing member fixed on the casing, a plurality of drives, and a cover having a clamping portion and forming a space cooperatively with the casing. The fixing member has engaging and pressing arms. The engaging arm is engaged with the circuit board when the clamping portion and the casing clamp the circuit board. The pressing arm has a hole for engaging with a protruding portion of the server to fix the drive module. The plurality of drives is inserted into the space and plugged into the circuit board. When the pressing arm is pulled toward a first direction or a second direction opposite to the first direction, the hole is disengaged from the protruding portion or the pressing arm drives the engaging arm to be separate from the circuit board.
