Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional air-cooled server slide rails are used for immersion servers, then the server can be installed vertically, but the server is prone to direct collision damage due to operational errors
Solution Approach 1:
The patent applies beforehand cushioning by pre-installing a buffer structure at the end of the slide rail before any collision can occur. The buffer structure includes a buffer spring and buffer block that are预先 positioned to absorb impact energy when the server cart hits the end of the rail, preventing direct collision damage to the server equipment.
Solution Approach 2:
The buffer structure acts as an intermediary element between the server cart and the fixed rail. When collision occurs, the buffer spring and buffer block intervene to absorb and dissipate impact energy, preventing direct contact between the server cart and the hard surface of the fixed rail, thus protecting the server from damage.
2Object-affected harmful factors
If a buffer structure is added to the slide rail, then collision damage is prevented, but the device complexity increases
Solution Approach 1:
The buffer structure is segmented into distinct functional components: a buffer block for initial contact, a buffer spring for energy absorption, and a mounting structure for integration. This segmentation allows each component to be optimized independently and facilitates easy installation and maintenance, reducing overall system complexity despite adding buffering functionality.
Solution Approach 2:
The buffer structure is designed to be nested within or integrated into the existing slide rail structure. The buffer block and spring are housed within a compact mounting structure that attaches to the fixed rail, allowing the buffering function to be added without significantly increasing the overall footprint or complicating the slide rail's external dimensions.
3Object-affected harmful factors
If the buffer structure uses elastic members and liquid coolant, then impact absorption is improved, but the manufacturing complexity increases
Solution Approach 1:
The buffer structure employs self-service principles where the buffer spring automatically compresses and rebounds to absorb and dissipate impact energy without requiring external control systems. The liquid coolant in the buffer chamber automatically responds to impact forces, providing additional damping without requiring active pumping or control mechanisms, thereby simplifying manufacturing while maintaining effective impact absorption.

Function Achieved in This Case
The buffer structure effectively prevents collision damage by using the liquid coolant to absorb impacts, ensuring the server's longevity and operational reliability, while maintaining structural compactness and ease of operation.
Implementation Method 1
elastic members arranged between the bottoms of the guide pins and the bottoms of the buffer chambers
Implementation Method 2
the liquid coolant of the server passes through the small holes in the tail portion of the buffer tank to enter the buffer chambers and fills up the chambers

AI summary
The present invention relates to a buffer structure for immersion server slide rail and a working method therefor, which belongs to the field of server slide rails. The buffer structure is composed of a buffer tank, buffer chambers, small holes, guide pins, elastic members and a buffering block. When the slide rail is open, due to the fact that the elastic members undergo a loss of compression, the guide pins and the buffering block are pushed to move outwards, the server's liquid coolant enters the buffer chambers through the small holes in the tail portion of the buffer tank and fills up the chambers, and the buffering block stops moving when abutting against the first position-limiting stopper; whereas when the slide rail is closed, the tail portion of the first moveable rail abuts against the buffering block to generate an inward thrust, pushing the buffering block and the guide pins to move inwards, and the guide pins press against the elastic members and the liquid coolant in the buffer chambers, thereby forming a buffer. In this way, the present invention is made to be structurally compact, rational, easy to operate, enabling automatic buffering, thereby preventing collision damage that may be caused by excessive impact during operation, reducing accidental damage that may be caused by undesirable operation, and prolonging the server's lifespan.
