Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional slide rail assemblies are not adaptable to chassis of different sizes, resulting in insufficient support and stability issues during installation.
Innovation Solution
A slide rail assembly comprising a first rail, a second rail slidably connected to the first rail, a third rail with a support portion and a movably connected support member, and a resilient member generating elastic force to ensure the stop portion contacts the chassis, providing adjustable support for various chassis sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional slide rail assemblies are used, then the structure is simple, but they cannot adapt to chassis of different sizes and provide sufficient support
Solution Approach 1:
The slide rail assembly is divided into multiple segments: a first rail, a second rail that slides relative to the first, and a third rail with a support portion. This segmentation allows each component to perform specific functions and enables the assembly to adapt to different chassis lengths through relative movement of the segments.
Solution Approach 2:
The second rail is configured to slide relative to the first rail, and the support member can move along the third rail. This dynamic configuration allows the assembly to adjust its length and support position according to different chassis sizes, providing adaptability while maintaining structural integrity.
2Adaptability or versatility
If the slide rail assembly is extended to support longer chassis, then support coverage is improved, but stability may be compromised without proper support
Solution Approach 1:
The resilient member is pre-configured to generate elastic force that automatically pushes the stop portion of the support member against the chassis. This preliminary action ensures that contact and support are established before the chassis is fully installed, maintaining stability throughout the installation process.
Solution Approach 2:
The support member acts as an intermediary between the third rail and the chassis. It transmits the elastic force from the resilient member to the chassis through the stop portion, providing stable support while allowing for adjustments in chassis length.
3Adaptability or versatility
If fixed support structures are used, then manufacturing is simple, but they cannot provide adjustable support for various chassis sizes
Solution Approach 1:
The slide rail assembly is designed as a universal structure that can support chassis of different lengths. The combination of sliding rails and movable support members allows a single assembly design to serve multiple chassis sizes, eliminating the need for different fixed support structures for different applications.

AI summary
A slide rail assembly includes a first rail, a second rail, a third rail, a support member and a resilient member. The second rail is slidably connected to the first rail to which the third rail is connected. The support member is movably connected to the third rail and has a side portion and a stop portion. The side portion has at least one first slot, and a first connecting member extends through the at least one first slot and is connected to the third rail. The resilient member generates an elastic force in response to a relative movement between the support member and the third rail. The support member is movable relative to the third rail and contacts against the chassis.
