Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional modular information handling system designs face challenges in providing adequate mechanical support and alignment for increasing component density within limited space, leading to space constraints and inefficiencies in chassis design.
Innovation Solution
A structural subassembly with a first portion for one type of information handling resource and a second portion for another, divided by a common wall, featuring mechanical features that engage with the chassis for guiding and retaining the subassembly during insertion and removal, and providing electrical coupling through connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If component density is increased in information handling systems, then space utilization is improved, but mechanical support and alignment become insufficient
Solution Approach 1:
The chassis is divided into multiple structural portions (first portion, second portion, third portion) that can independently support different information handling resources. This segmentation allows each portion to be optimized for specific mechanical support requirements while collectively achieving high component density throughout the chassis.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement by positioning components at different heights and orientations within the chassis. The structural portions extend in multiple directions and provide support at various levels, effectively using vertical and lateral dimensions to increase component density without compromising mechanical strength.
2Volume of moving object
If component density is increased, then space requirements are reduced, but alignment precision deteriorates
Solution Approach 1:
The structural portions act as intermediary elements between the chassis framework and the information handling resources. These intermediaries provide precise alignment features such as guide rails, positioning slots, and mounting surfaces that ensure accurate placement of components while enabling compact arrangement within the chassis.
Solution Approach 2:
Different regions of the chassis are provided with specialized structural portions having different geometric characteristics and alignment features tailored to the specific requirements of each information handling resource type. This local optimization ensures precise alignment for each component while maintaining overall high density.
3Ease of operation
If modular components are used for ease of installation, then operational ease is improved, but structural support becomes insufficient
Solution Approach 1:
The modular information handling resources are divided into discrete, independently installable units that can be easily inserted into and removed from the chassis. Each module is designed to interface with specific structural portions, providing straightforward installation while the distributed structural portions collectively ensure adequate structural support for all modules.
Solution Approach 2:
The structural portions serve as intermediary mounting structures that facilitate easy module installation through standardized interfaces, guide rails, and retention mechanisms. These intermediaries translate the ease of modular installation into secure, supported configurations within the chassis.

AI summary
A structural subassembly for use in an information handling system chassis may include a first portion, a second portion, a common wall, and one or more mechanical features. The first portion may be configured to receive one or more of a first type of information handling resource. The second portion may be configured to receive one or more of a second type of information handling resource. The common wall may divide the first portion from the second portion. The one or more mechanical features may be configured to engage with one or more respective mechanical features of the information handling system chassis in order to perform at least one of guiding of the subassembly relative to the information handling system chassis during insertion or removal of the subassembly into or from the information handling system chassis and retention of the subassembly relative to the information handling system chassis.
