Slide Rail Assembly with Resilient Locking for Narrow-Space Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies face challenges in being easily operable within narrow spaces, particularly in releasing the locking mechanism to accommodate varying market demands and spatial constraints.
Innovation Solution
A slide rail assembly with a resilient engaging member and a locking mechanism that allows the second rail to lock with the engaging member when moving from one position to another, featuring a synchronizing member and a third rail that drives the second rail to a locked position, and an operating member to release the lock, ensuring the assembly can be easily operated within narrow spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is used to secure the second rail to the first rail, then the stability and reliability of the slide rail assembly is improved, but the ease of operation within narrow spaces deteriorates due to the complexity of releasing the lock
Solution Approach 1:
The resilient portion of the engaging member is designed to automatically engage with the locking member when the second rail moves to the locked position, eliminating the need for manual intervention to establish the lock. The resilient portion's inherent elasticity enables automatic engagement without requiring additional actuators or complex release mechanisms, thus improving reliability while maintaining ease of operation.
Solution Approach 2:
The resilient portion acts as an intermediary between the locking member and the operating member. It translates the movement of the second rail into automatic engagement with the locking member, and conversely, transmits the releasing force from the operating member to disengage the lock. This intermediary mechanism simplifies the release operation by providing a mechanical advantage that works within narrow spaces.
2Strength
If the locking mechanism is designed with robust engagement features, then the strength and stability of the connection is improved, but the device complexity increases making it harder to operate within narrow spaces
Solution Approach 1:
The locking mechanism is segmented into distinct functional components: the locking member with its blocking feature, the engaging member with its resilient portion, and the operating member. Each component has a specific function, and their simplified individual designs collectively achieve strong connection without excessive overall complexity. The blocking feature is a simple protruding structure rather than a complex interlocking mechanism.
Solution Approach 2:
Instead of designing a complex mechanism that actively secures the rails together, the invention uses a resilient portion that passively engages with the locking member through elastic deformation. The strength comes from the resilient portion's material properties and geometric design rather than complex mechanical interlocks, thereby reducing overall device complexity while maintaining connection strength.
3Reliability
If the slide rail assembly is designed for secure locking, then the reliability is improved, but the ease of manufacture deteriorates due to additional precision requirements
Solution Approach 1:
The resilient portion is designed to self-adjust during assembly, compensating for minor manufacturing tolerances. Its elastic properties allow it to deform and engage with the locking member even when there are slight variations in the dimensions of the blocking feature or mounting positions, thereby maintaining locking reliability without requiring extremely tight manufacturing tolerances.
Solution Approach 2:
The resilient portion's material properties and geometric parameters are optimized to provide sufficient engagement force while accommodating manufacturing variations. By adjusting the resilience parameters (such as material hardness, cross-section dimensions, and mounting distances), the design achieves reliable locking with standard manufacturing capabilities, avoiding the need for high-precision machining or specialized assembly processes.

AI summary
A slide rail assembly comprises a first rail, an engaging member, a second rail and a locking member. The engaging member is arranged on the first rail and comprises a resilient portion. The second rail is movable relative to the first rail. The locking member is movably mounted on the second rail. When the second rail at a first position moves to a second position in a first direction relative to the first rail, the locking member locks with the resilient portion of the engaging member to prevent the second rail at the second position from moving in a second direction.
