Solution Overview

Problem

Conventional rack mount storage units have limited capacity for hard disk drives due to space constraints, requiring multiple enclosures for large data storage and complicating easy access for maintenance and replacement.

Innovation Solution

A side loading enclosure design with integrally connected plates and slide rails allows for increased HDD capacity by mounting drives perpendicularly and enabling horizontal access, along with a vertical mount rack storage unit that accommodates multiple enclosures, increasing storage density.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If hard disk drives are arranged in removable carriers accessible from the front of the enclosure, then individual drives can be replaced easily, but the number of HDDs that can be mounted is limited by the front area space

Engineering Contradiction:
Improveease of drive replacementVSAvoidnumber of drives per enclosure
Core Design Contradiction:
Ease of repairVSQuantity of substance

Solution Approach 1:

The patent transitions from traditional front-accessible drive arrangement to side-loading configuration where drives are mounted perpendicular to the bottom plate and accessed horizontally. This dimensional change allows drives to be arranged in multiple rows extending between end plates, effectively utilizing the side area of the enclosure rather than being constrained by the front panel space, thereby increasing the total number of drives while maintaining easy replacement capability

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Quantity of substance

If multiple enclosures are used to increase storage capacity, then more data can be stored, but the system complexity and space requirements increase

Engineering Contradiction:
Improvestorage capacityVSAvoidnumber of enclosures
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent combines multiple drive stacks into a single enclosure by arranging them in parallel rows that share common end plates and connecting members. This merging approach consolidates what would traditionally require multiple separate enclosures into one unified structure, increasing storage capacity while reducing the number of discrete units needed in the rackmount storage system

Inventive Principle:
Principle #5Merging (Combining)

3Quantity of substance

If drives are mounted perpendicular to the bottom plate in multiple rows, then storage density increases, but cable management and connectivity complexity increases

Engineering Contradiction:
Improvestorage densityVSAvoidcable and connector arrangement
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent employs universal connecting members that can interface with multiple stacks of drives simultaneously. These connecting members serve multiple functions by providing both structural support for the perpendicular drive mounting and electrical connectivity to all drives in a row, thereby managing cable and connector complexity while enabling high storage density through perpendicular multi-row configuration

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A side loading enclosure for a rack mount type storage unit is provided. The enclosure provides for easier access to hard disk drives (HDDs) for maintenance and repair as well as the ability to increase the number of HDDs that can be mounted in a single enclosure. The enclosure may include a bottom plate, a pair of side plates, and a pair of end plates. Located within the enclosure are a first row, extending perpendicularly between the pair of end plates, having one or more stacks of HDDs mounted to a first printed circuit board and a second row, extending perpendicularly between the pair of end plates, having one or more stacks of HDDs mounted to a second printed circuit board. The one or more stacks of HDDS in the first row is separate from and located parallel to the one or more stacks of HDDs in the second row.
