Refrigerator Door Quick-Release Latch for Fast Drawer Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing refrigerator doors are cumbersome and prone to damage or improper alignment due to the need for unscrewing and rescrewing multiple fasteners, leading to difficulties during installation.
Innovation Solution
A quick release mechanism featuring a latch and keeper, where the latch is pivotally coupled to the door and the keeper is U-shaped, allowing the door to be easily attached and detached without tools, utilizing a spring to bias the latch for secure sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fasteners (screws) are used to attach the door, then the connection is secure and reliable, but the installation and removal process becomes time-consuming and complex
Solution Approach 1:
The fastening system is divided into separate functional components: a keeper attached to the drawer slide and a latch attached to the door. This segmentation allows the latch to be quickly engaged with the keeper without requiring multiple fasteners, thus reducing installation time while maintaining connection reliability through the dedicated latch-keeper interface.
Solution Approach 2:
The latch is designed as a movable component that can pivot between engaged and disengaged positions. This dynamic mechanism allows for quick attachment and detachment of the door, eliminating the need for time-consuming screw operations while ensuring secure connection when engaged through the latch-keeper interface.
2Strength
If multiple fasteners are used to secure the door, then the connection strength is sufficient, but the procedure becomes difficult and prone to damage
Solution Approach 1:
The complex multi-fastener system is extracted and replaced with a simplified latch-keeper mechanism. The keeper is attached to the drawer slide and the latch to the door, creating a direct engagement system that maintains connection strength while dramatically improving ease of operation by eliminating difficult screwing and unscrewing procedures.
Solution Approach 2:
The latch mechanism is designed to be self-aligning and self-latching when brought together with the keeper. This self-service characteristic allows users to attach the door without requiring precise alignment or special tools, making the procedure easy to perform while ensuring adequate connection strength through the engaged latch-keeper interface.
3Reliability
If traditional fastening methods are used, then the door can be securely attached, but improper installation is more likely causing sealing or alignment issues
Solution Approach 1:
The keeper acts as an intermediary component that provides a defined engagement interface between the drawer slide and door latch. This intermediary structure guides the latch into proper alignment during attachment, ensuring correct positioning and sealing alignment while maintaining secure attachment through the latch-keeper engagement.
Solution Approach 2:
The keeper is pre-attached to the drawer slide at the correct position and orientation during manufacturing. This preliminary action ensures that when the latch is engaged during installation, proper alignment and sealing position are automatically achieved, reducing the likelihood of improper installation while maintaining attachment reliability.

AI summary
A refrigerator includes a refrigerated compartment and a drawer having a drawer slide, a door and a quick release mechanism. The drawer slide allows the drawer to slide into and out of the refrigerated compartment, and the door selectively seals the refrigerated compartment. The quick release mechanism removably couples the door to the drawer slide. The quick release mechanism includes a latch and a keeper. The latch is pivotally coupled to one of the door and the drawer slide, and the keeper has a slot for receiving the latch.
