Quick-Mount Slide Rail With Stepped Connectors for Rack Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional quick-mount slide rails for server racks suffer from insufficient connection strength and stability due to the formation of a long lever arm when fitting into mounting holes of varying sizes, which affects the ability to support the weight of servers.
Innovation Solution
A tool-less quick-mount slide rail design featuring a connector slide module with movable locking positions and stepped cylindrical connectors that adjust to fit into different-sized mounting holes, ensuring the connectors do not form a long lever arm relative to the rack, thereby enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stepped cylindrical connector uses the smallest cylindrical segment to fit into a small mounting hole, then the connector can be fitted into the mounting hole, but a long lever arm is formed which reduces connection strength and stability
Solution Approach 1:
The connector slide module is designed to be movable along the front-rear direction, allowing dynamic adjustment of the connector's position. This enables the system to adapt to different mounting hole sizes while maintaining optimal connection strength by selecting appropriate locking positions rather than being fixed in a single position that creates a long lever arm.
Solution Approach 2:
The invention changes the position parameter of the connector relative to the bracket by providing multiple locking positions. By adjusting the connector's position along the front-rear direction, the system can optimize the lever arm length for different mounting scenarios, thereby maintaining connection strength while adapting to various hole sizes.
2Adaptability or versatility
If the stepped cylindrical connector uses the smallest cylindrical segment to fit into a small mounting hole, then the connector can be fitted into the mounting hole, but the assembly stability is reduced due to the long lever arm
Solution Approach 1:
The movable connector slide module with multiple locking positions allows the system to dynamically adjust to different mounting configurations. This dynamic positioning capability ensures assembly stability by enabling the connector to be positioned optimally for each specific mounting hole size rather than being constrained to a fixed position that creates instability.
Solution Approach 2:
By providing multiple locking positions that change the connector's position parameter along the front-rear direction, the invention enables optimization of the lever arm length. This parameter adjustment maintains assembly stability across different mounting hole sizes while preserving adaptability.
3Adaptability or versatility
If the connector is positioned to fit small mounting holes, then small holes can be accommodated, but the lever arm length increases which adversely affects connection strength
Solution Approach 1:
The dynamic positioning mechanism allows the connector to be moved to different locking positions based on the mounting hole size. This ensures reliable connections by enabling optimal positioning for each scenario rather than being forced into a fixed position that compromises connection reliability when adapting to different hole sizes.
Solution Approach 2:
The invention changes the position parameter of the connector to optimize the lever arm length for different mounting scenarios. By providing multiple locking positions, the system can adjust the connector's position to maintain connection reliability while accommodating various hole sizes.

AI summary
A quick-mount slide rail is adapted to be disposed on a rack. The quick-mount slide rail includes a bracket and a connector slide module. The bracket includes a side plate and a front plate extending perpendicularly from a front edge of the side plate, and having two through holes. The connector slide module is disposed on the bracket and is movable relative to the side plate among a plurality of locking positions. The connector slide module includes a connector sliding block that has a block body and two stepped cylindrical connectors extending respectively through the through holes. Each stepped cylindrical connector has cylindrical segments. Outer diameters of the cylindrical segments decrease sequentially and forwardly. When the connector slide module is moved to a selected locking position, one of the cylindrical segments of each stepped cylindrical connector protrudes forwardly from the front plate for at least a predetermined distance.
