Pivotal Riser Board Memory Staggering for Space Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computer systems face challenges in maximizing memory module placement within limited server space due to the occupation of space by control chips on riser boards, leading to inefficient use of space between boards.
Innovation Solution
A memory combination featuring two pivotally connected riser boards that can rotate to be perpendicular to each other, allowing memory sockets on one board to face the other, with sockets staggered in an alternate manner to prevent interference and increase capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple riser boards are closely arranged on the main board with memory modules facing the same direction, then the structure is simple and easy to manufacture, but the control chip occupies space that cannot be configured with memory sockets, reducing space utilization
Solution Approach 1:
The patent changes the arrangement from a single-plane configuration to a three-dimensional staggered arrangement. Memory sockets on adjacent riser boards are positioned at different depths and angles, allowing space that would normally be occupied by control chips to be utilized by memory modules on neighboring boards. This dimensional change enables more efficient space utilization while maintaining structural simplicity.
2Quantity of substance
If memory modules are densely packed in limited server space, then memory capacity is increased, but memory modules may collide or interfere with each other
Solution Approach 1:
The patent implements a nested arrangement where memory modules on adjacent riser boards are positioned in staggered rows at different depths. The memory modules are arranged like nested dolls, with each board's memory sockets offset from its neighbors. This nesting approach allows maximum density while preventing physical collision and electrical interference between modules on different boards.
3Ease of operation
If riser boards are arranged with memory sockets in the same direction, then installation is straightforward, but the space between boards corresponding to control chips remains idle
Solution Approach 1:
The patent introduces asymmetric staggering between adjacent riser boards. While memory sockets on each individual board remain uniformly arranged for easy installation, the relative positioning between boards is asymmetric and offset. This asymmetry allows memory modules to occupy the previously idle space between boards, eliminating waste space while maintaining installation simplicity through standardized socket orientations on each board.

AI summary
A memory combination includes a first riser board, a second riser board, and a pivotal plate. The first riser hoard includes a plurality of first memory sockets of which long axis directions are parallel to each other. The second riser board includes a plurality of second memory sockets of which long axis directions are parallel to each other. Two end of the pivotal plate are pivotally connected to the first riser board and the second riser board based on an axial direction respectively. When the first and second riser boards rotate to be perpendicular to the pivotal plate, the first memory sockets face the second riser board, and the second memory sockets face the first riser board. The axial direction is perpendicular to the long axis directions of the first memory sockets and the long axis directions of the second memory sockets.
