Main Board Expansion Slot Layout for 1U and 2U Server Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server designs face challenges in accommodating both standard and low profile expansion cards efficiently, particularly in optimizing space utilization within the limited heights of 1U and 2U cases, which hinders the integration of multiple cards and affects the server's expansion capability and energy efficiency.
Innovation Solution
The server design incorporates a main board assembly with strategically arranged expansion slots and a switching circuit that allows for the installation of both standard and low profile expansion cards, with carefully defined distances between slots to accommodate different card widths, enabling flexible card placement and improved space utilization across various case heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the server case height is reduced to 1U or 2U to minimize physical space usage, then space utilization is improved, but the ability to accommodate both standard and low profile expansion cards is compromised
Solution Approach 1:
The base board is segmented into multiple regions with different expansion slots (first expansion slot, second expansion slot, third expansion slot) positioned at different locations. Each slot can accommodate different types of expansion cards (standard or low profile) based on its position and spacing, allowing the single base board to support both card types in compact 1U/2U cases
Solution Approach 2:
Instead of relying solely on vertical space (height) to differentiate card accommodation, the design utilizes horizontal positioning and spacing relationships between expansion slots. The distances between slots are specifically designed to accommodate different card widths, transforming the problem from a vertical dimension constraint to a horizontal layout solution
2Power
If multiple expansion cards are installed to enhance server capability for big data processing, then processing power is improved, but space utilization and energy efficiency deteriorate
Solution Approach 1:
The expansion slot configuration is designed to be universal, supporting both standard and low profile expansion cards across different case heights (1U and 2U). This multi-functionality allows the server to be deployed in various form factors without redesign, enabling flexible scaling of processing capability while maintaining energy efficiency through appropriate card selection and placement
Solution Approach 2:
The design changes physical parameters (distances between expansion slots) to accommodate different expansion card types. By adjusting the spacing between slots based on card width requirements, the system can optimize the number and type of expansion cards installed, balancing processing power with space and energy constraints
3Adaptability or versatility
If different case heights (1U and 2U) are supported to increase market adaptability, then versatility is improved, but development and manufacturing complexity increases
Solution Approach 1:
A single base board design with specifically positioned expansion slots can accommodate both 1U and 2U case heights. The universal slot configuration allows the same motherboard to be used across different form factors, eliminating the need for separate development and manufacturing processes for different case heights, thereby reducing complexity and cost

AI summary
A main board assembly for being equipped with at least one of a standard expansion card and a low profile expansion card includes a base board, a first expansion slot, a second expansion slot, a third expansion slot and a switching circuit. There is a first distance between the second expansion slot and the first edge, and there is a second distance between the second expansion slot and the third expansion slot, which are greater than the width of the standard expansion card. There is a third distance between the first expansion slot and the third expansion slot, which is two times greater than the width of the low profile expansion card.
