Adjustable Refrigerator Door Guide Assembly for Variable Food Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerator door guides are fixed and cannot be adjusted to accommodate food of varying heights, leading to inefficiencies in storing and retrieving items while maintaining the cold air inside the storage chamber.
Innovation Solution
A door guide assembly that is removably coupled to the refrigerator door, featuring a moving unit with a catching portion and stopper mechanism, allowing for up-down movement and adjustment of the guide's position to match the height of stored food, while a latch system secures the stopper in place to prevent rotation and ensure proper alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the door guides are fixed in the opening, then the structure is simple and stable, but the heights of the door guides cannot be adjusted according to the heights of food stored
Solution Approach 1:
The door guide assembly is designed with movable components that allow dynamic adjustment of height. The moving unit can slide along the guide rail, and the stopper mechanism can be positioned at different locations to secure the door guide at various heights, transforming a static structure into a dynamic, adjustable one.
Solution Approach 2:
The door guide assembly is divided into separate functional components: the guide rail, the moving unit, the stopper, and the latch. This segmentation allows each component to perform its specific function independently while working together as a complete adjustable assembly, resolving the contradiction between adjustability and complexity.
2Adaptability or versatility
If the door guide assembly includes multiple components for adjustment, then the adaptability increases, but the ease of manufacture decreases
Solution Approach 1:
The door guide assembly uses standardized components with universal functions. The guide rail provides both guidance and support, the moving unit handles both movement and positioning, and the stopper serves both as a positioner and a locking element when engaged with the latch. This multi-functionality reduces the need for specialized parts, easing manufacture.
3Ease of operation
If the door guide can move up and down, then the ease of operation improves, but the reliability of fixing the position decreases
Solution Approach 1:
The stopper mechanism is designed to automatically engage with the guide rail at the desired position when the moving unit is stationary. The gravitational force and the mechanical interaction between the stopper and guide rail provide self-locking, ensuring the door guide remains securely fixed without requiring additional active locking components during normal operation.
4Reliability
If the latch mechanism is added to fix the stopper, then the position stability improves, but the device complexity increases
Solution Approach 1:
The latch acts as an intermediary element that connects the stopper to the moving unit. Instead of designing a complex direct locking mechanism between the stopper and the guide rail, the latch mediates this connection, providing a simple yet effective locking action that enhances position stability without significantly increasing overall system complexity.

AI summary
An integral door guide assembly is removably coupled in an opening of a door of a refrigerator and has an adjustable height. The refrigerator includes a first door rotatably connected to a front surface of a main body, and having an opening in which a plurality of door guide assemblies can be arranged, and a second door rotatably connected to a front surface of the first door. The door guide assembly includes a door guide, a guide removably fixed on both side walls of the opening, a moving unit removably coupled with both side walls of the door guide, guided by the guide to move in an up-down direction, a stopper coupled with the guide, and caught by or released from the catching projections to adjust a position of the moving unit and a latch configured to fix the stopper released from the catching projections.
