Universal Drawer Slide with Adjustable Cam for Dual-Side Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer slides with lock-in and lock-out features require separate left and right-hand slides, increasing inventory and labor costs, as they need to operate in specific directions, which is inefficient for applications like emergency and commercial vehicles where flexibility in mounting is necessary.
Innovation Solution
A universal drawer slide that can be mounted on either side of a cabinet, featuring a cam that can be adjusted to allow both levers to operate in the same direction, enabling the same slides to be used for both sides with minimal adjustments, and includes both lock-in and lock-out mechanisms for flexible operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate left and right drawer slides are used to ensure proper lever operation direction, then the drawer slide reliability is improved, but the device complexity and inventory requirements increase
Solution Approach 1:
The drawer slide is designed with a universal configuration that can function on both left and right sides of a cabinet. The cam mechanism can be oriented in different positions (first and second positions) to accommodate different mounting orientations, allowing a single drawer slide design to replace what would traditionally require separate left-hand and right-hand slides. This multi-functional design reduces inventory requirements while maintaining proper lever operation direction on both sides.
2Adaptability or versatility
If the cam position is adjusted to enable universal mounting on either side, then the adaptability is improved, but the ease of operation may be affected
Solution Approach 1:
The cam mechanism is designed to be adjustable between different positions. The cam can be oriented in a first position for mounting on one side of the cabinet and in a second position for mounting on the opposite side. This dynamic adjustability allows the same drawer slide to adapt to different mounting orientations while maintaining consistent lever operation characteristics through proper cam orientation.
3Productivity
If a single universal drawer slide design is used for both sides, then the manufacturing efficiency is improved, but the precision of lever-cam engagement may deteriorate
Solution Approach 1:
The drawer slide incorporates asymmetric cam positioning that accounts for the different mounting orientations. By providing specific first and second cam positions that correspond to left and right side mounting respectively, the design maintains precise lever-cam engagement for each orientation while using a single universal slide design. The asymmetric positioning ensures that the cam profile properly engages the lever in both mounting configurations without compromising precision.

AI summary
A universal drawer slide is described. The drawer slide includes an outer slide member and an inner slide member that are configured to move between a closed position and an extended position. A lever is pivotally mounted to a front portion of the inner slide member. A cam mounts to the outer slide member in at least a first position and a second position. An engaging end of the lever engages with the cam in either the first position or the second position.
