Drawer slide rail
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer slide rail designs lack sufficient structural strength due to insecure mounting of the base on the rail member, which affects the stability and adjustment of the gap between the drawer and the cabinet.
Innovation Solution
A drawer slide rail with a reinforced supporting structure featuring a base with multiple supporting arms and an adjustable supporting member, allowing for secure mounting and adjustable positioning to enhance structural integrity and ease of gap adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the base is mounted on the rail member to allow gap adjustment, then the ease of operation is improved, but the structural strength deteriorates due to insecure mounting
Solution Approach 1:
The base is divided into multiple supporting arms (first supporting arm, second supporting arm, third supporting arm) that contact different portions of the rail member. This segmentation allows the base to be mounted securely at multiple points while maintaining adjustment capability, resolving the contradiction between ease of operation and structural strength.
Solution Approach 2:
Different supporting arms contact different local regions of the rail member with specific geometries. The first supporting arm contacts the bottom portion, the second supporting arm contacts another bottom portion, and the third supporting arm contacts the lateral portion. This local quality approach ensures secure mounting at critical locations while preserving adjustment functionality.
2Strength
If the base structure is reinforced to improve structural strength, then the strength is improved, but the device complexity increases due to multiple supporting arms
Solution Approach 1:
Multiple supporting arms are merged into a single integrated base structure. The first, second, and third supporting arms are all part of one base component that mounts to the rail member, reducing the number of separate parts while achieving reinforced structural strength through multi-point contact.
Solution Approach 2:
The base structure serves multiple functions simultaneously: it provides structural reinforcement through multiple supporting arms, enables gap adjustment through the adjustable supporting member, and secures mounting on the rail member. This multi-functionality reduces overall device complexity by combining several functions into one component.

AI summary
A drawer slide rail includes a longitudinal body and a base. The longitudinal body includes a pair of first sidewalls extending respectively from two sides of a front end portion of the longitudinal body and a pair of second sidewalls respectively connected to the first sidewalls and extending respectively from two sides of the longitudinal body. The base is mounted on the front end portion of the longitudinal body and includes first to third supporting arms. The first supporting arm is pressed against a bottom portion of one of the first sidewalls. The second supporting arm is pressed against a bottom portion of one of the second sidewalls. The third supporting arm is pressed against a lateral portion of one of the second sidewalls.
