Slide rail assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies are prone to deformation or damage when supporting heavy objects, as the front section of the inner slide member can exceed its loading capacity over time, leading to structural weaknesses.
Innovation Solution
The slide rail assembly incorporates a reinforcing structure, such as a metal supporting member or ribs, between the front and rear portions of the second rail, which protrudes beyond the first rail when extended, providing enhanced structural strength and preventing deformation or damage from overweight loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the inner slide member is designed with a simple structure, then the device complexity is reduced and ease of manufacture is improved, but the strength and load-bearing capacity deteriorate when supporting heavy objects
Solution Approach 1:
The inner slide member is divided into a front section and a rear section, with the rear section having a larger cross-sectional area than the front section. This segmentation allows each section to be optimized independently - the front section maintains a smaller profile for ease of manufacture and installation, while the rear section provides enhanced strength to support heavy loads without requiring the entire member to be oversized.
2Strength
If the inner slide member is designed with sufficient strength to support heavy loads, then the strength parameter is improved, but the front section may still deform under prolonged heavy loading
Solution Approach 1:
The patent applies local quality by giving different cross-sectional areas to different sections of the inner slide member. The rear section has a larger cross-sectional area specifically positioned where heavy loads are applied, providing localized strength enhancement. This allows the structure to have varying properties along its length - stronger where needed and lighter where not required - preventing deformation under prolonged heavy loading while maintaining overall structural stability.

AI summary
A slide rail assembly (22) includes a first rail (28), a second rail (30), and a reinforcing structure (32). The first rail (28) includes a front end portion (38) and a rear end portion (40). The second rail (30) is displaceable with respect to the first rail (28). The reinforcing structure (32) is located at the second rail (30). A portion of the reinforcing structure (32) protrudes beyond the front end portion (38) of the first rail (28) when the second rail (30) is displaced from a first position (P1) to a second position (P2) with respect to the first rail (28).
