Drawer Slide Locking Rail for Vibration-Resistant Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional slide devices with locking functions are cumbersome to manufacture and difficult to operate, as they require separate locking structures that complicate the prevention of movable bodies from undesirably sliding due to external vibrations, leading to potential damage and injury from articles falling out.
Innovation Solution
A slide device with a locking function that integrates a fixed rail, a first movable rail, and a second movable rail, featuring a locking unit at the inner front end of the fixed rail and a locked member with a spring support, allowing secure locking and easy release for smooth operation, preventing sliding during external vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate locking structure is added to prevent sliding due to external vibrations, then the reliability of preventing undesired sliding is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The locking structure is integrated into the slide device itself rather than being a separate component. The locking protrusion and locking groove are formed as integral parts of the movable rail and fixed rail respectively, merging the locking function with the sliding mechanism to reduce overall device complexity while maintaining reliability.
Solution Approach 2:
The movable rail serves multiple functions: it enables smooth sliding movement of the drawer and simultaneously provides the locking function through its integrated locking protrusion. This multi-functionality eliminates the need for separate locking structures, reducing device complexity while ensuring reliable prevention of undesired sliding during vibrations.
2Ease of manufacture
If a locking structure is integrated into the slide device, then the ease of manufacture is improved, but the ease of operation for opening drawers deteriorates
Solution Approach 1:
The locking member is designed to be movable rather than fixed, allowing it to transition between locked and unlocked states. This dynamic design enables easy operation of the drawer while maintaining the integrated locking structure that simplifies manufacturing. The locking member can be actuated by the user to release the lock when opening the drawer.
3Reliability
If a complex locking structure is provided, then the reliability of preventing sliding is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The locking protrusion and locking groove are formed as integral parts of the rail structures during the same manufacturing process, merging multiple functions into single components. This reduces the number of parts that need to be manufactured and assembled, significantly improving ease of manufacture while maintaining reliable locking functionality.
Solution Approach 2:
The movable rail integrates both the sliding function and locking function into a single component. The locking protrusion is formed as part of the movable rail structure itself, eliminating the need for separate locking components and simplifying the manufacturing process while ensuring reliable prevention of undesired sliding.
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
The integrated locking mechanism effectively secures the movable rail to the fixed rail, preventing the movable body from sliding away due to external vibrations, thus protecting stored articles and ensuring safety, while allowing easy operation by releasing the locking state for smooth drawer opening.
Implementation Method 1
a locked member pivotally installed at an outer front end of the second movable rail, to be locked to the locking unit of the fixed rail by a pivot support pin

AI summary
There is provided a slide device with a locking function to smoothly support the movement of a movable body, such as a drawer, to be movably installed in a fixed body, such as a box-type frame, which comprises: a fixed rail fixedly mounted on the fixed body; a first movable rail movably installed in the fixed rail in a forward-backward direction; a second movable rail movably installed in the first movable rail in the forward-backward direction and fixedly mounted on the movable body; a locking unit positioned at an inner front end of the fixed rail, to lock the second movable rail; and a locked member pivotally installed at an outer front end of the second movable rail, to be locked to the locking unit of the fixed rail by a pivot support pin.
