Rack Slide Rail Assembly With Movable Brackets for Longer Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional slide rail assemblies for racks have limited extension length and insufficient supporting capability, failing to meet market requirements for longer extension and improved support.
Innovation Solution
The slide rail assembly comprises a first rail, first and second brackets, and a second rail, where the first rail is movable relative to the brackets and the rack, allowing for extended travel and enhanced support by incorporating rolling members and an engaging mechanism to prevent retraction, enabling longer extension and improved support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the first rail is fixedly mounted to the rack through fixed brackets, then the structure is simple and stable, but the extension length is limited
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed bracket-rail connection into a movable connection. The first bracket is configured to be movable relative to the first rail, allowing the first rail to move along the rack when mounted. This dynamic connection enables the extension length to be increased while maintaining structural stability through the engagement and disengagement mechanisms.
2Length of moving object
If the first rail is movable relative to the rack through movable brackets, then the extension length is increased, but the supporting capability may be reduced
Solution Approach 1:
The patent applies segmentation by dividing the supporting function into multiple components: the first bracket supports the first rail during movement, the engaging member provides stabilization at predetermined positions, and the rolling member reduces friction. This segmented approach maintains supporting capability while enabling extended movement.
Solution Approach 2:
The patent introduces a rolling member as an intermediary between the first bracket and the first rail. This rolling member reduces friction and enables smooth movement while maintaining supporting capability, resolving the contradiction between movability and support strength.
3Strength
If engaging members are added to prevent retraction, then the supporting capability is enhanced, but the device complexity increases
Solution Approach 1:
The engaging member is configured to automatically engage with the first rail when it moves to a predetermined position along the rack. This self-service mechanism provides stabilization without requiring external control systems, enhancing supporting capability while minimizing the increase in device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design allows for increased extension length and enhanced supporting strength of the slide rails, improving the carrying capacity and stability of objects mounted on the rack by allowing the first rail to move relative to the rack, thus extending the travel distance of the second and third rails.
Implementation Method 1
The first bracket and the first rail are movable relative to each other through the at least one rolling member
