Slide Rail Assembly with Arced Auxiliary Member for Guided Reinsertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies face challenges in efficiently reinserting and guiding rails back into their passages after being drawn out, requiring increased user effort and potential frictional resistance.
Innovation Solution
The introduction of an auxiliary member with an arced contour adjacent to the passage opening of the first rail, which guides the second rail for reinsertion and reduces friction through a supporting member with an arced contour, facilitating smooth movement and reduced force requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional slide rail assembly is used without an auxiliary guiding member, then the structure is simple, but the second rail is difficult to reinsert and align into the passage after being drawn out
Solution Approach 1:
An auxiliary member with an arced contour is introduced as an intermediary guiding structure positioned adjacent to the passage opening. This auxiliary member acts as a mediator that guides the second rail during reinsertion into the passage, making the operation easier without requiring complex active mechanisms.
Solution Approach 2:
The auxiliary member is designed with an arced (curved) contour that corresponds to the curvature needed to guide the second rail back into the passage. This curved geometry naturally guides the rail during reinsertion, converting a difficult linear alignment task into a smoother curved path insertion.
2Force
If a traditional slide rail assembly is used without friction-reducing features, then the structure is simple, but the force required to move the rail is high
Solution Approach 1:
The arced contour of the auxiliary member and the corresponding arced supporting surface create a curved guidance path that reduces friction during reinsertion. The curved geometry allows the rail to be guided back into the passage with reduced frictional resistance compared to forced linear alignment.
3Ease of operation
If the auxiliary member is added to guide the second rail, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The auxiliary member serves as a simple intermediary guiding element that provides alignment assistance during reinsertion. By positioning this single auxiliary component adjacent to the passage opening, the patent achieves improved alignment ease without requiring multiple complex active guiding mechanisms.
