Slide Rail Kit with Recessed First Rail for Increased Width Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail kits for racks face limitations in structural strength and assembly complexity due to the need for shorter first rails to fit within limited spaces, which compromises the ability to carry objects with larger widths.
Innovation Solution
The slide rail kit includes a first rail with a recessed structure on its outer side, allowing a portion of the rack's side frame to extend into a concave space, thereby enabling longer first rails without the need for additional extension members, and allowing for increased width capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the first rail is designed to be shorter to fit within the space between front post and rear post of the rack, then the lateral space occupied by the first rail is reduced, but the overall structural strength of the slide rail is reduced
Solution Approach 1:
The recessed structure on the outer side of the first rail allows the side frame of the rack to extend into the concave space, creating a nested configuration where the rack structure is integrated into the rail structure. This nesting enables the first rail to be shorter while maintaining structural strength through the combined rigidity of the rail and rack framework.
Solution Approach 2:
The recessed structure introduces a dimensional change by creating a concave space that accommodates the rack's side frame. This dimensional modification allows the first rail to achieve both reduced lateral footprint and maintained structural strength by utilizing the vertical and depth dimensions of the recessed area.
2Area of stationary object
If the first rail is designed to be shorter to fit within limited space, then lateral space usage is improved, but the ability to carry objects with larger widths is compromised
Solution Approach 1:
By nesting the rack's side frame into the recessed structure of the first rail, the effective carrying width is extended beyond the physical length of the first rail. The second rail can extend further outward to carry wider objects while the recessed first rail maintains a compact lateral profile when viewed from the outside.
3Strength
If additional extension members are added to increase the length of the first rail, then the structural strength is improved, but the assembly complexity of the slide rail assembly is increased
Solution Approach 1:
The recessed structure integrates the function of an extension member directly into the first rail's body, eliminating the need for separate extension components. The concave space is formed as an integral part of the first rail structure, reducing the total number of parts and simplifying assembly while maintaining the necessary structural strength.
4Adaptability or versatility
If additional extension members are added to accommodate wider objects, then the width capacity is increased, but the assembly complexity is increased
Solution Approach 1:
The recessed structure merges the accommodation function for wider objects directly into the first rail's design. By integrating the concave space that accepts the rack's side frame, the system achieves increased width capacity without requiring additional extension members or complex assembly procedures.

AI summary
A slide rail kit includes a first rail, a second rail and a bracket device. The first rail has an outer side and an inner side. The second rail is movable relative to the first rail and located adjacent to the inner side of the first rail. The bracket device is arranged on the first rail and includes a rack mounting feature. A recessed structure is formed at the outer side of the first rail and adjacent to the rack mounting feature.
