Slide rail assembly and mounting method for slide rails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies face difficulties in aligning and mounting the third rail with the second rail due to obstruction by the carrier, making the assembly process inconvenient for users.
Innovation Solution
A slide rail assembly with a guiding structure comprising first, second, and third guiding portions on the first rail, which facilitates the mounting of the second rail into the channel by guiding it in the height or transverse direction, preventing obstruction and ensuring accurate alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the third rail is mounted to the second rail in a direction D, then the carrier can be extended or retracted, but the carrier blocks the user's sight and makes alignment difficult
Solution Approach 1:
The guiding structure changes the mounting direction from the longitudinal direction (direction D) to the height direction. The second rail is guided to approach the channel opening from above or below, and then enters the channel vertically, completely avoiding the line of sight blockage caused by the carrier.
Solution Approach 2:
The guiding structure acts as an intermediary component between the second rail and the channel opening. It includes a guiding portion that extends beyond the channel opening in the height direction to guide the second rail during mounting, facilitating alignment without requiring the user to look past the carrier.
2Ease of operation
If the guiding structure is added to facilitate mounting, then alignment is improved, but the device complexity increases
Solution Approach 1:
The guiding structure is integrated with the first rail structure. The guiding portion is formed as part of the first rail assembly, combining the guiding function with the existing structural components, thereby minimizing additional complexity while achieving the alignment improvement.
Solution Approach 2:
The guiding portion extends beyond the channel opening in the height direction by a specific distance (e.g., 5-15mm) to provide sufficient guidance during mounting. This partial extension is enough to facilitate alignment without adding excessive structural complexity.
