Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies for carrying items like UPS systems face challenges in achieving both smooth operation and safety while maintaining a simple structure, often resulting in either inadequate performance or complex, costly designs.
Innovation Solution
A slide rail assembly comprising a first elongated web plate with L-shaped upper and lower folded panels forming a slide chute, and a nested second slide rail with L-shaped panels and a recess, providing a simple yet strong structure that enhances guiding and stopping mechanisms, allowing for smooth and secure operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If additional mechanisms such as roller wheels, roller balls, or gear wheels are added between the inner rail and outer rail to reduce friction resistance, then the smoothness and stability of operation is improved, but the structure becomes more complex and costs increase
Solution Approach 1:
The patent removes the complex additional mechanisms (roller wheels, roller balls, gear wheels) from the slide rail assembly, extracting only the essential sliding function. The inner rail slides directly on the outer rail through a simplified structure with L-shaped folded panels that provide guiding and support without requiring additional moving parts or complex components.
Solution Approach 2:
The slide rail components are segmented into simple L-shaped folded panels that are punched out from integral sheets. These panels are distributed along the inner and outer rails to provide localized support and guiding functions, replacing the need for complex continuous mechanisms while maintaining operational smoothness through multiple discrete contact points.
2Reliability
If a damping mechanism is provided between the inner and outer rails to prevent damage from excessive applied force, then the security and reliability is improved, but the structure becomes more complex and costs increase
Solution Approach 1:
The L-shaped folded panels are designed with inherent geometric features that provide cushioning and force distribution before excessive force can cause damage. The folded structure creates natural cushioning zones that absorb impact forces during operation, preventing damage to the slide rail assembly or cabinet without requiring separate damping mechanisms.
3Reliability
If position limiting means or positioning mechanisms are provided on the slide rail assembly to improve security during use, then the reliability is improved, but the structure becomes more complex and costs increase
Solution Approach 1:
The positioning and limiting functions are merged into the basic L-shaped folded panel structure itself. The geometry of the folded panels inherently provides position limiting by defining the sliding path and stop positions, eliminating the need for separate positioning mechanisms. The same structural elements that provide support also provide positioning and security functions.

AI summary
A slide rail assembly comprising: a first slide rail (10, 10′) comprising a first, elongated web plate (11, 11′), a front surface facing toward a carried item (80) in use and a back surface facing away from the carried item in use; a second slide rail (20, 20′) nested within the first slide rail and being movable relative to the first slide rail in length direction. The upper edge of the first web plate is provided with a first, L-shaped upper folded panel (12, 12′) extending at an angle of 90 degrees with regard to the back surface of the first web plate, the lower edge thereof is provided with a horizontal supporting panel (13, 13′) for supporting the item which is bended at an angle of 90 degrees with regard to the front surface of the first web plate, and the first web plate is also provided with at least one first, L-shaped lower folded panel (14, 14′) opposite to the first upper folded panel and extending at an angle of 90 degrees with regard to the back surface of the first web plate, with the first upper folded panel and the at least one first lower folded panel collectively constituting a slide chute for supporting and guiding the second slide rail sliding therein.
