Slide Rail Connecting Structure for Precise Drawer Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail systems face challenges in accurately mounting drawers due to minor errors during the mounting process, leading to alignment issues between the drawer and the slide rail, which existing solutions attempt to address but at the cost of increased production complexity and cost.
Innovation Solution
A slide rail system with a front connecting device featuring an adjusting element and an engaging element, allowing for transverse adjustment of the drawer's position relative to the slide rail, and a rear connecting device with a locking element for aligning the slide rail assembly, utilizing a screw rod and elastic arm mechanism for precise alignment and disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing adjustment mechanisms are used to correct mounting errors, then alignment precision is improved, but device complexity and production cost increase
Solution Approach 1:
The patent integrates the adjustment function directly into the connecting device structure by combining the connecting element with transverse guiding portions and adjustment slots, eliminating the need for separate adjustment mechanisms while maintaining alignment precision
Solution Approach 2:
The connecting device serves multiple functions simultaneously: it connects the drawer to the slide rail, provides transverse adjustment capability, and guides alignment all through a single integrated structure, reducing overall device complexity
2Manufacturing precision
If existing adjustment mechanisms are used to correct mounting errors, then alignment precision is improved, but production cost increases
Solution Approach 1:
By merging the adjustment functionality into the existing connecting device structure through integration of adjustment slots and guiding portions, the patent eliminates the need for separate adjustment components, thereby reducing production cost while maintaining alignment precision
Solution Approach 2:
The connecting device enables self-adjustment during installation through its integrated transverse guiding portions and adjustment slots, allowing workers to correct mounting errors without requiring complex external adjustment tools or procedures
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 precise adjustment and alignment of the drawer with respect to the slide rail, effectively addressing mounting errors while simplifying the manufacturing process and reducing production costs.
Implementation Method 1
The adjusting element has an adjusting portion and a screw rod. The screw rod is connected to the first unit and the second unit. The second unit is displaceable relative to the second rail in response to rotation of the adjusting portion of the adjusting element

AI summary
A slide rail assembly includes first and second rails. The second rail, slidable relative to the first rail, has a mounting hole. A connecting device includes first and second units, an engaging element, and an adjusting element. The second unit has a transverse guiding portion located at its counterpart of the first unit. The engaging element, connected to the second unit, has an engaging portion partially located in the mounting hole to connect the connecting device to the second rail. The adjusting element is connected to both units. The second unit is displaceable in response to rotation of the adjusting element, thereby enabling displacement of the engaging portion relative to the mounting hole.
