Slide Rail Kit with Recessed Structure for Wider Object Accommodation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies face limitations in structural strength and assembly complexity due to the need for additional extension members to accommodate larger objects, while maintaining a compact design.
Innovation Solution
A slide rail kit with a recessed structure on the first rail that allows a portion of the rack's side frame to extend into a concave space, enabling the second rail to carry wider objects without requiring the first rail to be shortened, thus maintaining structural integrity and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the first rail is shortened to reduce lateral space occupied, then the slide rail can fit within the space between front post and rear post, but the overall structural strength is reduced
Solution Approach 1:
The recessed structure allows the side frame to extend into the concave space formed by the recessed structure, creating a nested configuration where the side frame is partially housed within the rail structure. This nesting arrangement maintains structural strength by utilizing the space efficiently without requiring the rail to be shortened.
2Area of moving object
If the first rail is shortened to accommodate wider objects, then the second rail can carry objects with larger width, but additional extension members are required increasing assembly complexity
Solution Approach 1:
The recessed structure integrates the function of what would otherwise require separate extension members into the first rail itself. By forming a concave space directly in the rail body, the design combines the support function and the space-providing function into a single structural feature, eliminating the need for additional components and simplifying assembly.
3Area of stationary object
If the first rail is shortened to reduce lateral space, then the slide rail fits within rack boundaries, but the recessed structure requires the side frame to extend into concave space
Solution Approach 1:
The recessed structure creates a localized concave space at a specific position on the first rail, allowing the side frame to extend into this localized area. This local modification enables the rail to maintain its overall length and structural integrity while providing the necessary space accommodation in a specific region.
