Multi-Rail Slide Rail Assembly for Wider Rack Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies have a width limitation due to space restrictions, preventing the accommodation of wider carried objects in rack systems, as they are typically configured with slide rails of fixed dimensions.
Innovation Solution
A slide rail assembly design featuring a mounting member with multiple rails, where the third rail is movable relative to the first rail and the second rail is movable relative to the fourth rail, allowing for increased flexibility and width accommodation by synchronizing or unsynchronizing the movement of the rails using an engaging member and elastic member, and incorporating slide assisting devices and buffer members for structural strength and impact absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the width of slide rail assembly is increased to accommodate wider carried objects, then the carrying capacity is improved, but the rack space utilization deteriorates due to insufficient space
Solution Approach 1:
The patent transitions from a traditional single-plane horizontal arrangement to a three-dimensional configuration where rails are arranged both horizontally and vertically. The mounting member supports multiple rails at different heights, allowing the system to utilize vertical space within the rack, thereby increasing carrying capacity without consuming additional horizontal rack space.
Solution Approach 2:
The slide rail assembly is divided into multiple independent rails (first rail, second rail, third rail, fourth rail) that can move independently or in coordination. This segmentation allows the system to distribute the load across multiple rails arranged in different spatial positions, effectively increasing the overall carrying capacity while maintaining a compact footprint.
2Area of moving object
If multiple rails are arranged in parallel to increase width, then the carrying capacity is improved, but the device complexity increases
Solution Approach 1:
Multiple rails are integrated onto a single mounting member, which serves as a unified structural platform. The mounting member combines the support functions for multiple rails into one component, reducing the overall number of separate parts and simplifying the assembly structure while still providing multi-rail functionality.
Solution Approach 2:
The patent incorporates engaging members that can dynamically connect or disconnect between different rails based on operational requirements. This dynamic configuration allows the system to adjust its complexity - when rails need to move independently, the engaging members disengage; when synchronized movement is needed, the engaging members connect the rails, providing adaptability without permanent complexity.
3Adaptability or versatility
If rails are made movable relative to each other to increase flexibility, then the adaptability is improved, but the reliability deteriorates due to potential misalignment or instability
Solution Approach 1:
The mounting member serves as an intermediary structure that provides a stable reference frame for the movable rails. By anchoring multiple rails to this common mounting member, the system ensures that even when rails move relative to each other, they maintain proper alignment and spacing, preventing misalignment issues while preserving movement flexibility.
Solution Approach 2:
The patent employs engaging members that can dynamically transition between engaged and disengaged states. When engaged, these members provide additional constraints and stability to prevent misalignment; when disengaged, they allow independent rail movement. This dynamic control mechanism maintains reliability during movement operations.
