Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of information handling system chassis increases due to various add-in card (AIC) form factors, leading to increased differentiation and complexity in system configurations.
Innovation Solution
The use of sleeve adapters that convert larger AIC bays into multiple smaller sleeve bays, allowing for the accommodation of different AIC form factors and routing data signals accordingly, thereby simplifying chassis configurations and accommodating various form factors within a single chassis bay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple CEM form factors are used to accommodate various system configurations, then adaptability is improved, but device complexity increases
Solution Approach 1:
The invention segments the chassis bay structure by introducing removable sleeve adapters that divide a single bay into multiple smaller bays. Each sleeve adapter can be independently installed or removed to accommodate different AIC form factors, thereby segmenting the chassis configuration options without permanently increasing structural complexity.
Solution Approach 2:
The invention introduces dynamic configurability through removable sleeve adapters that allow the chassis to adapt its bay structure based on installation needs. The sleeve adapters can be dynamically added or removed to change the number and type of AICs supported, transforming a static chassis structure into a dynamic one that responds to configuration requirements.
2Adaptability or versatility
If multiple chassis configurations are designed to accommodate different AIC combinations, then adaptability is improved, but manufacturing complexity increases
Solution Approach 1:
The invention creates a universal chassis bay design that can accommodate multiple AIC form factors through the use of standardized sleeve adapters. Instead of designing multiple specialized bays for different AIC types, a single universal bay design配合 various sleeve adapters achieves multi-functionality, simplifying manufacturing while maintaining adaptability.
Solution Approach 2:
The sleeve adapter acts as an intermediary component between the standardized chassis bay and various AIC form factors. This intermediary allows the chassis to support different AIC types without requiring specialized bay designs, thereby reducing manufacturing complexity while maintaining versatility.
3Device complexity
If sleeve adapters are used to convert larger AIC bays into smaller bays, then device complexity is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The invention manages manufacturing precision requirements by standardizing the physical and electrical parameters of sleeve adapters. By defining specific parameters such as adapter dimensions, connector positions, and signal routing configurations, the design ensures that while precision is required, it is concentrated in standardized components rather than varying across different chassis configurations.

AI summary
Add-in card (AIC) adapters or sleeve adapters, suitable for use with information handling system chassis defining one or more AIC bays suitable for receiving a first AIC form factor, convert the bay into two or more sleeve-defined bays. Each sleeve bay is suitable for receiving a different and typically smaller form factor. For example, a chassis with an Enterprise and Data Center Standard Form Factor (EDSFF) E5 double wide bay may include a sleeve adapter defining two E5 single wide sleeve bays, each of which is suitable for receiving a corresponding E5 single wide AIC form factor. In another example, a sleeve adapter may be configured to convert an E5 double wide bay into one or more sleeve bays configured for a legacy CEM form factor. Sleeve adapters may route a subset of PCIe data lanes associated with a bay to each sleeve bay defined by the sleeve adapter.
