Solution Overview

Problem

Current blade server chassis lack physical support during maintenance, leading to inconvenient and potentially damaging handling practices due to limited space in server rooms.

Innovation Solution

A blade server assembly that includes a support assembly connected to both the blade server chassis and the blade server, allowing it to be supported substantially outside the chassis, facilitating easier access and maintenance without the need for awkward positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If blade server is installed inside the blade server chassis, then space utilization is improved, but maintenance convenience deteriorates

Engineering Contradiction:
Improvespace utilizationVSAvoidmaintenance convenience
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The support assembly enables the blade server to be dynamically positioned between two states: installed inside the chassis for space-efficient operation, and extended outside the chassis for convenient maintenance. The support assembly includes a support surface that can be positioned to hold the blade server in either configuration, allowing transition between compact storage and accessible maintenance modes.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If blade server is removed from the chassis for maintenance, then maintenance access is improved, but handling safety deteriorates

Engineering Contradiction:
Improvemaintenance accessVSAvoidhandling safety
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The support assembly acts as an intermediary device between the blade server chassis and the maintenance personnel. It provides a dedicated support surface that safely holds the blade server during maintenance operations, eliminating the need for personnel to awkwardly support or balance the server on their knees or other unstable surfaces. The support assembly includes a support surface configured to receive and securely hold the blade server.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If blade server is supported outside the chassis during maintenance, then maintenance convenience is improved, but device complexity increases

Engineering Contradiction:
Improvemaintenance convenienceVSAvoidchassis structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The support assembly is implemented as a separate, modular component distinct from the main blade server chassis structure. This segmentation allows the support functionality to be added without fundamentally redesigning the chassis, and the support assembly can be independently configured and adjusted. The support surface is positioned to work in conjunction with the chassis without being integrated into its core structure.

Inventive Principle:
Principle #1Segmentation

AI summary

A blade server assembly is disclosed that includes a blade server chassis, a blade server, and a support assembly connected with the blade server chassis and with the blade server so as to support the blade server substantially outside the blade server chassis. A method is also disclosed for maintaining a blade server installed in a blade server chassis that includes supporting the blade server substantially outside the blade server chassis through a support assembly connected with the blade server chassis and with the blade server.
