Adjustable Refrigerator Door Guide Assembly for Variable Food Heights
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, thereby optimizing storage and minimizing cool air leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 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 heights to secure the door guide at desired positions, transforming a static structure into a dynamic, adjustable one.
Solution Approach 2:
The door guide assembly is divided into separate functional components: a guide rail, a moving unit, a stopper, and a latch. This segmentation allows each component to perform its specific function independently while working together as a system, enabling height adjustment without requiring complete structural redesign.
2Adaptability or versatility
If door guides are fixed, then manufacturing and installation are simple, but they cannot accommodate food of varying heights
Solution Approach 1:
The door guide incorporates a moving unit that can dynamically adjust its position along the guide rail, allowing accommodation of food items with different heights. The stopper mechanism can be set at various heights to maintain the door guide in the appropriate position for different storage needs.
3Adaptability or versatility
If door guides are movable to adjust height, then flexibility is improved, but the risk of cool air leakage increases if not properly secured
Solution Approach 1:
The latch mechanism is designed to automatically engage and secure the stopper in place once the door guide is positioned at the desired height. This preliminary securing action ensures that the movable door guide is firmly fixed before use, preventing any unintended movement that could cause cool air leakage while maintaining the flexibility to adjust heights.
4Reliability
If a securing mechanism is added to fix the movable door guide, then reliability is improved, but device complexity increases
Solution Approach 1:
The latch mechanism automatically engages with the stopper to secure the door guide in place once positioned. This preliminary securing action ensures stable positioning without requiring complex manual intervention or additional components, as the latch self-activates to maintain reliability.

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.
