Three-Rail Slide Assembly for Heavy Chassis Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies face challenges in mounting heavy objects due to insufficient strength, leading to deformation or damage, and previous mounting methods are either inconvenient in limited spaces or require excessive space, lacking versatility.
Innovation Solution
A slide rail assembly with a first rail, a second rail, and a third rail, featuring a releasing feature and an engaging member that allows synchronous movement and detachment, enabling flexible mounting options by communicating apertures and holes for mounting heavy objects without requiring extensive space or lifting.

Engineering Contradiction Analysis
1Weight of moving object
If the third rail is used to carry heavy objects, then the carrying capacity is improved, but the third rail may deform or damage due to insufficient strength
Solution Approach 1:
The slide rail assembly is divided into three separate rails (first rail, second rail, third rail) that can be used independently or in combination. This segmentation allows the first and second rails to provide additional support when heavy objects need to be carried, while the third rail can still be used independently for lighter objects, thus preventing overload damage.
Solution Approach 2:
The third rail is designed to serve multiple functions: it can be used independently for mounting light objects, or in combination with the first and second rails for mounting heavy objects. This multi-functionality allows the same component to adapt to different load requirements without requiring separate structures.
2Area of stationary object
If the drop-in mounting method is used to mount a chassis, then the mounting space is reduced, but the chassis must be lifted higher than the slide rail assembly which is inconvenient when located near the top position
Solution Approach 1:
The mounting process is segmented into two independent methods: Method 1 uses all three rails together for mounting, and Method 2 uses only the third rail for mounting. This segmentation allows users to choose the appropriate method based on the installation location and space constraints, improving operational flexibility.
Solution Approach 2:
The system provides dynamic mounting options where the third rail can be detached from the first and second rails to create different mounting configurations. This dynamic reconfigurability allows the system to adapt to different spatial requirements during installation and operation.
3Ease of operation
If the inner rail is pulled out and detached for mounting, then the chassis can be mounted without lifting, but the mounting method requires larger space than the drop-in method
Solution Approach 1:
The third rail is designed to function in multiple mounting configurations: it can be used as part of a three-rail assembly or detached as a standalone mounting rail. This universality allows the same component to serve different mounting needs without requiring additional parts or increasing space requirements.
4Weight of moving object
If the third rail is made stronger to carry heavy objects, then the carrying capacity is improved, but the device complexity increases
Solution Approach 1:
Instead of making the third rail stronger and more complex, the system segments the load-bearing function across three separate rails. Each rail maintains a simple, lightweight structure, but when combined, they provide the necessary strength for heavy objects. This segmentation avoids increasing individual component complexity while achieving the required carrying capacity.

AI summary
A slide rail assembly comprises a first rail, a second rail, a third rail and an engaging member. The first rail comprises a releasing feature. The second rail is movable relative to the first rail. The third rail is movable relative to the second rail. The engaging member is pivoted to the second rail. Wherein, the engaging member is configured to engage with the third rail to allow the second rail and the third rail to be synchronously moved relative to the first rail along a first direction, and the releasing feature is configured to disengage the engaging member from the third rail when the second rail is synchronously moved with the third rail relative to the first rail to a predetermined position.
