Solution Overview

Problem

The challenge of increasing storage density in servers without compromising computing performance is exacerbated by the limited available mounting space, as adding more hard disks reduces space for computing assemblies, affecting data processing speed.

Innovation Solution

A storage server design with a sliding storage tray and vertical arrangement of hard disks, combined with a computing assembly stacked perpendicular to the storage assembly, allows for efficient use of space, enabling high storage density and computing performance through modular components like adapter plates and golden fingers for reliable data transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the number of hard disks is increased to satisfy storage density, then storage capacity is improved, but available mounting space for computing assemblies is reduced

Engineering Contradiction:
Improvenumber of hard disksVSAvoidmounting space for computing assemblies
Core Design Contradiction:
Quantity of substanceVSArea of stationary object

Solution Approach 1:

The patent transitions from traditional horizontal arrangement of hard disks to a vertical arrangement where hard disks are stacked along the height direction of the server. This dimensional change allows multiple hard disks to be positioned in the same horizontal footprint, dramatically increasing storage density without encroaching on the horizontal mounting space required for computing assemblies. The vertical stacking approach utilizes the third dimension (height) to resolve the space conflict between storage and computing components.

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

Solution Approach 2:

The patent implements a nested structure where hard disks are vertically stacked within a confined space, similar to nested dolls. Multiple hard disks are arranged one above another in a vertical column, with each disk positioned within the vertical envelope of the server chassis. This nesting approach maximizes the use of vertical space, allowing a high number of hard disks to coexist in a compact volume without interfering with the horizontal space needed for computing assemblies.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Quantity of substance

If more hard disks are added to increase storage density, then storage capacity is improved, but data processing speed is affected

Engineering Contradiction:
Improvestorage capacityVSAvoiddata processing speed
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The patent divides the storage system into multiple independent hard disk units that can operate in parallel. Each hard disk maintains its own data processing channel, allowing simultaneous read/write operations across multiple disks. This segmentation of storage into parallel-operating units increases overall data throughput and processing speed, counteracting the potential slowdown that might result from increased storage density.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs dynamic resource allocation and load balancing mechanisms that allow the system to adaptively manage data processing tasks across multiple hard disks. The system can dynamically assign computing tasks to available processing units, optimize data access patterns, and balance the workload to maintain high processing speeds even as storage capacity scales up.

Inventive Principle:
