Front-Mount Interlocking Sliding Rail for Easy Drawer Lock Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rear-mount type interlocking sliding rail assemblies are difficult to repair as the interlocking mechanism is installed at the rear side, making it challenging to replace when damaged.
Innovation Solution
A front-mount type interlocking sliding rail assembly with a sliding rail system comprising an outer rail, intermediate rail, inner rail, bracket, swivel member, limiter blocks, and a switching mechanism that allows for easy installation and repair by positioning the interlocking mechanism at the front side, ensuring positive interlocking operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the interlocking mechanism is installed at the rear side of the sliding track assembly, then the structural design is conventional and compact, but it becomes difficult to remove and replace the interlocking mechanism when damaged
Solution Approach 1:
The patent inverts the conventional rear-mount configuration by positioning the interlocking mechanism at the front side of the sliding track assembly. This inversion allows the interlocking mechanism to be easily accessed, removed, and replaced from the front, directly resolving the repair difficulty while maintaining conventional structural design benefits
2Ease of repair
If the interlocking mechanism is positioned at the front side, then installation and repair become facilitated, but the structural configuration becomes non-conventional
Solution Approach 1:
The patent applies inversion by placing the interlocking mechanism at the front side rather than the conventional rear side. This non-conventional positioning is intentionally designed to facilitate easy access for installation and repair operations, accepting the structural configuration change as a trade-off for improved maintainability
3Device complexity
If a simple sliding rail structure is used, then the device complexity is reduced, but the interlocking operation may not be sufficiently positive or reliable
Solution Approach 1:
The patent applies local quality by concentrating the interlocking function in a specific localized mechanism at the front of the sliding rail assembly. This localized interlocking mechanism, while simple in overall structure, provides positive and reliable interlocking operation through its specific geometric configuration and engagement features
Solution Approach 2:
The interlocking mechanism is designed to automatically engage and disengage through the natural movement of the sliding rail components. The mechanism self-regulates the interlocking operation through its inherent mechanical geometry, ensuring positive and reliable function without requiring external control systems or complex additional components

AI summary
A front-mount type interlocking sliding rail assembly includes a sliding rail assembly formed of an outer rail, an intermediate rail and an inner rail, a bracket affixed to the outer rail, a swivel member pivoted to the bracket and having two opposite protruding blocks and an actuating block, first limiter and second limiter disposed at two opposite sides and movable by the swivel member, a switching block affixed to the inner rail and having two opposing wings respectively suspending in between a base portion and two stop flanges of the bracket, and a push member located on one wing and adapted for pushing the actuating block to bias the swivel member.
