System Board Support Frame With Arc Mounting to Reduce Sagging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As server technology advances, the increased weight of components leads to sagging in server chassis, which can exceed height limitations and cause contact with adjacent servers, and pre-bowing sheet metal alone is insufficient to mitigate this issue.
Innovation Solution
A support member with a frame and mounting members is introduced, where the mounting members form an arc to bend the system board, reducing sagging and preventing contact between adjacent servers by bowing the system board in an upward direction, and a handle member is used for easy insertion and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If pre-bowing sheet metal is used to reduce sagging, then the sagging is reduced to some extent, but it becomes insufficient when component weight increases
Solution Approach 1:
The support member is pre-configured with mounting members positioned to bend the system board into an upward arc before installation. This preliminary action creates a pre-tensioned structure that actively counteracts the downward sagging force caused by heavy components, rather than merely pre-bowing the chassis sheet metal which provides insufficient counteraction.
Solution Approach 2:
The support member acts as an intermediary element between the system board and the server chassis. It includes a frame with mounting members that connect to the system board, providing structural reinforcement and creating an upward arc that mediates the stress distribution, preventing direct transmission of heavy component weight to the chassis while maintaining board stability.
2Productivity
If the system board is made heavier with advanced components, then computing power and component density increase, but sagging increases and exceeds height limitations
Solution Approach 1:
The mounting members are positioned to bend the system board into a curved upward arc rather than leaving it flat. This curvature creates a structural form that naturally resists downward bending forces, allowing the board to support heavier high-performance components while maintaining proper vertical clearance and preventing contact with adjacent servers.
3Stability of the object's composition
If a rigid support structure is added to prevent sagging, then stability improves, but device complexity increases
Solution Approach 1:
The support member is divided into a frame structure with multiple discrete mounting members positioned at specific locations on the system board. This segmentation allows each mounting member to provide localized support and create the upward arc effect, achieving stable board positioning without requiring a monolithic complex support structure.
