Server Chassis Dual-Rail Design to Reduce Slide Structure Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current server chassis designs require significant internal space for slide rail structures, limiting the number of stacked layers and data storage units due to their bulky configuration.
Innovation Solution
A server chassis design featuring a pair of outer rail structures on the inner walls of the outer case and a pair of inner rail structures on the outer walls of the chassis body, utilizing a single-layer ball slide rail and inner rail-plate configuration to reduce occupied space, allowing for more data storage units and enhanced practicality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a three-section slide rail structure is used, then good supporting is achieved, but more internal space is occupied and the number of layers stacked is reduced
Solution Approach 1:
The slide rail structure is divided into two separate components: an outer rail structure fixed to the cabinet and an inner rail structure attached to the chassis body. This segmentation allows each component to be optimized independently, reducing the overall space required while maintaining the three-section functionality through coordinated movement of both rails.
Solution Approach 2:
The patent transitions from a traditional single bulky slide rail to a dual-rail configuration where the outer and inner rails work together in different spatial dimensions. The outer rail provides primary support while the inner rail enables precise movement, effectively utilizing three-dimensional space more efficiently and reducing the footprint of the rail system.
2Quantity of substance
If multiple data storage units are arranged in arrays, then data storage capacity is increased, but the weight of the server increases
Solution Approach 1:
The dual-rail slide mechanism distributes the weight of multiple data storage units across two separate rail structures (outer and inner rails), effectively counterbalancing the increased load. This allows the chassis to support higher weights while maintaining smooth movement and extraction functionality.
