Solution Overview
Problem
Existing artificial intelligence servers face issues with GPU modules colliding with server connectors due to excessive installation forces, leading to potential damage.
Innovation Solution
A damping mechanism with a bracket, stop assembly, and damping pad that engages when excessive force is applied, preventing the bracket from moving and stopping the GPU module, thereby avoiding connector collision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the GPU module is allowed to slide freely into the server casing, then the installation process is simple and fast, but the GPU module may collide with the server connector due to excessive installation force causing damage
Solution Approach 1:
The damping mechanism is pre-installed on the server casing before the GPU module is installed. The bracket is positioned in advance with the damping pad facing the potential impact direction. When the GPU module is slid in, if excessive force is applied, the impact is immediately absorbed by the pre-positioned damping mechanism, preventing connector collision without interfering with normal installation speed
Solution Approach 2:
The damping pad is installed on the bracket in advance as a protective cushion. This cushioning element is positioned before any potential impact occurs, so that when the GPU module is installed with excessive force, the damping pad absorbs the impact energy before it can reach and damage the server connector, thus protecting the connector while allowing free installation motion
2Reliability
If a damping mechanism is added to prevent GPU module collision, then connector protection is improved, but the device complexity increases
Solution Approach 1:
The damping mechanism is divided into separate functional components: a bracket that attaches to the server casing, a damping pad that absorbs impact, and a stop assembly with positioning members. This segmentation allows each component to be simple in itself while collectively providing comprehensive protection, reducing the overall complexity compared to a monolithic damping structure
Solution Approach 2:
The bracket serves as an intermediary structure between the server casing and the damping pad. It provides a mounting platform for the damping mechanism while maintaining a simple sliding capability along the installation direction. This intermediary structure simplifies the connection between the protective damping elements and the server casing, reducing structural complexity
3Reliability
If the bracket is constrained to prevent movement, then the GPU module is protected from collision, but the ease of operation during installation is reduced
Solution Approach 1:
The bracket is designed with dynamic characteristics, allowing it to slide freely along the installation direction during normal GPU module installation. The positioning members can move along the sliding groove without resistance. Only when excessive impact force is applied does the damping mechanism activate and provide constraint, thus maintaining ease of operation for normal installation while providing protection when needed
Solution Approach 2:
The damping mechanism activates automatically when excessive impact force is applied during GPU module installation. The positioning members naturally engage with the stop assembly under impact conditions without requiring external control or manual intervention. This self-activating protection maintains ease of operation for normal installation while providing automatic protection when needed

Implementation Method 2
the guide groove extends obliquely downward from the second end to the first end, and the rolling member is adapted to be located at the first end by gravity
