Drawer Slide Rail with Integrated Buffer and Auto-Bounce Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer slide rails lack effective mechanisms to control the opening and closing forces, leading to potential damage, noise, and inconvenience due to uncontrollable manual operations.
Innovation Solution
A buffer device on the slide rail with a buffer groove, buffer hook, and door bouncing mechanism, combined with pull springs and compression springs, allows for controlled automatic opening and closing of drawers, reducing impact and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional slide rails are used for drawer opening and closing, then the structure is simple and easy to manufacture, but the drawer operation is uncontrollable causing damage and noise
Solution Approach 1:
The patent combines multiple functions into a single integrated slide rail device: the buffer mechanism, bouncing mechanism, and slow-close function are all merged into one device that replaces conventional separate slide rails, achieving controlled drawer operation without requiring multiple separate components
Solution Approach 2:
The buffer mechanism is activated before the drawer completes its closing motion to cushion the impact and reduce closing speed, preventing damage and noise while maintaining a relatively simple overall structure
2Adaptability or versatility
If automatic slow-push mechanisms are installed to prevent over-opening, then damage and noise are reduced, but the drawer cannot be automatically ejected and operation convenience is limited
Solution Approach 1:
The bouncing mechanism uses spring elements that dynamically respond to the drawer's motion state, automatically ejecting the drawer when it is pushed closed by detecting the closing force and direction, thereby providing adaptability without requiring manual intervention
Solution Approach 2:
The device automatically detects the drawer's closing motion and activates the bouncing mechanism to eject the drawer without user intervention, making the system self-serving and enhancing operation convenience
3Object-affected harmful factors
If buffer devices are added to reduce impact during drawer closure, then damage and noise are prevented, but the device complexity increases
Solution Approach 1:
The buffer mechanism is integrated into the slide rail structure itself rather than being a separate add-on component, combining buffering, bouncing, and slow-close functions into one unified device to minimize the increase in overall structural complexity

AI summary
A device for auto-bouncing and slowly closing a drawer mainly provides a buffer device on a slide rail between a drawer and a left side opposite surface or right side opposite surface of a drawer slot, so that the impact is reduced and the drawer is automatically pulled back when the drawer is closed. At the same time, a door bouncing device is operated in coordination with, so that the drawer can be automatically eject to a specific position when the drawer is pressed, so as to achieve the multiple practicality.
