Slide rail assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies lack a user-friendly mechanism to easily operate and move the slide rail, particularly in scenarios requiring different market-specific configurations.
Innovation Solution
A slide rail assembly incorporating a handle, an auxiliary member, and an elastic feature, where the handle can switch between states, allowing the second rail to move from a retracted to an extended position, and the elastic feature engages the auxiliary member to hold the handle in the second state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional slide rail assembly without a handle is used, then the structure is simpler, but the ease of operation deteriorates as users cannot easily grip and move the slide rail
Solution Approach 1:
A handle is introduced as an intermediary component between the user and the second rail. The handle is movably connected to the second rail and can be gripped by users to easily move the slide rail assembly from retracted to extended position, without requiring direct manipulation of the rail itself.
Solution Approach 2:
The elastic feature automatically engages the auxiliary member with the handle when the second rail reaches the extended position, holding the handle in place without requiring user intervention. This self-servicing mechanism maintains the handle in the extended position state.
2Reliability
If a mechanism without state indication is used, then the structure is simpler, but the reliability deteriorates as users cannot determine the current state of the slide rail
Solution Approach 1:
The handle serves as a visual indicator of the slide rail assembly's state. When the second rail is in the extended position, the handle is automatically engaged by the elastic feature and positioned in a specific orientation that visually indicates the extended state to users, enhancing reliability through state visibility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy operation and movement of the slide rail by allowing users to switch the handle states, ensuring the slide rail can be efficiently extended and retracted, meeting various market requirements.
Implementation Method 1
the elastic feature is configured to accumulate a predetermined elastic force... the elastic feature is configured to release the predetermined elastic force to the auxiliary member

AI summary
A slide rail assembly includes a first rail, a second rail, a handle, an auxiliary member and an elastic feature. The handle is movable relative to the second rail. The auxiliary member is arranged on the second rail. When the second rail is located at a retracted position relative to the first rail, the auxiliary member abuts against the first rail, so as to allow the elastic feature to accumulate a predetermined elastic force. When the handle is moved to switch from a first state to a second state, the second rail is movable from the retracted position to an extended position along an opening direction, and the elastic feature releases the predetermined elastic force to the auxiliary member, such that the auxiliary member and the handle are engaged with each other to hold the handle in the second state.
