Refrigerator Door Case With Removable Sliding Container Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerator designs limit the efficient use of interior space due to fixed or slidingly mounted containers on the door, making it difficult to separate them from the door structure.
Innovation Solution
A refrigerator with a sliding apparatus that includes a guide rail on the container and a corresponding guide portion in the case, featuring a fixing rib and supporting rib to prevent movement, and a lever mechanism for easy release, allowing containers to be easily inserted or removed through an opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If containers are fixed on the door or configured to slide by a rail structure, then the containers can be mounted on the door, but it becomes difficult to separate the containers from the door
Solution Approach 1:
The mounting structure is divided into separate components: a case fixed on the door and containers that can be independently removed. The case contains guide portions and fixing ribs that provide mounting functionality, while containers have guide rails and supporting ribs for engagement. This segmentation allows containers to be easily separated from the door by removing them from the case, resolving the contradiction between ease of separation and mounting capability.
Solution Approach 2:
The case acts as an intermediary component between the door and the containers. It provides the mounting function through its guide portions and fixing ribs, while allowing containers to be easily removed. The case mediates the connection between the door structure and containers, enabling easy separation without requiring complex rail structures directly on the door.
2Ease of operation
If containers are fixed on the door, then the containers are securely mounted, but the inside space of the containers cannot be efficiently used
Solution Approach 1:
The mounting system transitions from a static fixed connection to a dynamic removable connection. Containers can be easily removed from the case by pulling them forward, allowing efficient access to the interior space. The guide rails and supporting ribs maintain secure mounting during normal use, while the lever mechanism enables easy removal when needed, resolving the contradiction between security and accessibility.
3Adaptability or versatility
If a rail structure is used to make containers slide, then containers can move on the door, but separating containers from the door becomes difficult
Solution Approach 1:
The sliding function is segmented from the mounting function. The case contains guide portions that provide sliding capability, while the containers have guide rails for engagement. This segmentation allows containers to slide within the case for versatility, while separation is achieved by simply removing containers from the case without dealing with complex rail structures, resolving the contradiction between sliding capability and ease of separation.

AI summary
A refrigerator is provided including a main body having a storage chamber, a door coupled with the front surface of the main body, to open or close the storage chamber, and a case having a rear surface facing the rear surface of the door the front part of the case having an opening. A container is in the case. A sliding apparatus enables the container to slide to be inserted into or pulled out of the case through the opening and includes a guide rail at a bottom of the container, an inclined guide portion in the case to guide the guide rail, a fixing rib at the rear end of the guide portion including a streamlined shape at the front end of the fixing rib and a supporting rib in the container supported by the fixing rib to prevent the container from moving.
