Slide rail assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies lack flexibility to meet diverse market requirements for moving and disconnecting carried objects from racks efficiently.
Innovation Solution
A slide rail assembly comprising a first rail, a second rail, and a handle, where the handle is movable relative to both rails, allowing it to unlock the second rail from a predetermined position and use a supporting feature to move the second rail or carried object to a new position, enabling easy disconnection of connected objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the handle is fixed to the second rail, then the structure is simple, but the handle cannot unlock the second rail at predetermined positions
Solution Approach 1:
The handle is designed to be movable relative to the second rail, transitioning between a locked position (where it engages the locking mechanism) and an unlocked position (where it can be manipulated). This dynamic mounting allows the handle to perform both locking and unlocking functions without requiring a separate fixed mounting structure.
2Reliability
If the handle directly moves the second rail without a supporting feature, then the structure is simple, but the rail cannot be reliably positioned at predetermined locations
Solution Approach 1:
The supporting feature is pre-positioned on the first rail at specific locations corresponding to predetermined positions. When the handle moves the second rail, these pre-positioned supporting features automatically guide and secure the rail at the correct locations, ensuring reliable positioning before final locking occurs.
3Adaptability or versatility
If the handle moves the second rail through the entire range without intermediate stops, then the operation is continuous, but the carried object cannot be disconnected at intermediate positions
Solution Approach 1:
The movement range of the second rail is segmented into multiple predetermined positions, each associated with a supporting feature. The handle can stop at any of these segmented positions, allowing the carried object to be disconnected at intermediate locations while maintaining continuous operational capability throughout the full range.

AI summary
A slide rail assembly (20, 200) comprises a first rail (38, 312), a second rail (40, 204) and a handle (48, 202). When the handle (48, 202) is moved from a first operating position to a second operating position, the handle (48, 202) is configured to unlock the second rail (40, 204) relative to the first rail (38, 312) at a predetermined position.
