Rotating HDD Tray Assembly for Tool-Free Perpendicular Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer chassis designs face limitations in space utilization due to the longitudinal space occupied by drives, drive trays, and drive backplanes, which restricts the accommodation of other components and cable management.
Innovation Solution
A drive tray assembly that allows drives to be oriented perpendicularly within the chassis, utilizing a rotatable outer tray and a slidable inner tray mechanism, enabling tool-free installation and retention via lower and side retention pegs, reducing longitudinal space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the long dimension of the HDD tray is aligned parallel to the y-axis (front-to-back axis) to maximize the number of HDDs that can be installed through the front, then the number of HDDs is improved, but the longitudinal space occupied by the HDD trays and HDD backplane increases
Solution Approach 1:
The patent rotates the HDD tray assembly 90 degrees so that the long dimension of the tray is aligned perpendicular to the y-axis (front-to-back axis) instead of parallel. This dimensional change allows HDDs to be installed through the front while occupying significantly less longitudinal space, resolving the contradiction between maximizing HDD quantity and minimizing longitudinal space occupation.
2Quantity of substance
If the HDD tray is designed to accommodate more HDDs, then the storage capacity is improved, but the space available for other components (motherboard, cable management) is reduced
Solution Approach 1:
By reorienting the HDD trays perpendicular to the y-axis, the patent frees up longitudinal space that can be allocated to other components such as larger motherboards and improved cable management areas, while still maintaining the same storage capacity through the front-accessible tray design.
3Ease of operation
If a rotatable outer tray and slidable inner tray mechanism are implemented to enable tool-free installation, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent implements a self-servicing mechanism where the slidable inner tray automatically engages with retention pegs on the motherboard when the outer tray is rotated into position. This self-engaging design eliminates the need for tools or manual fastening operations, improving ease of installation while keeping the mechanism relatively simple through automatic self-service functionality.

AI summary
A drive tray assembly is disclosed for placing drives (e.g., hard disk drives) in a computer chassis in a rotated orientation and without the need for additional tools. The drive tray assembly includes an outer tray on a hinge capable of being rotated away from the computer chassis during drive changes. An inner tray, upon which a drive may be placed, is coupled to the outer tray. When the outer tray is moved to a closed position within the computer chassis, pressing on a handle can cause the inner tray to move from a disengaged position to an engaged position, thus connecting the drive to a drive backplane within the computer chassis.
