Integrated Support Frame for Sliding-Door Basket Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerators with sliding doors and storage baskets on the rear portion create empty spaces between the basket's sidewalls and the inner case, limiting storage capacity and coupling force between the door and support frame.
Innovation Solution
The design includes a storage basket with protruding sidewalls and a support frame that accommodates the basket, featuring roller support surfaces, protrusions, and an auxiliary basket that operates in conjunction with the main basket, enhancing storage space and coupling force through a coupling structure with a coupling bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the storage basket is provided on the rear portion of the sliding door with conventional support, then the basic storage function is achieved, but empty spaces are created between the basket sidewalls and the inner case, limiting storage capacity
Solution Approach 1:
The support frame is nested within the storage basket structure, with the frame's sidewalls forming an integral part of the basket assembly. This allows the support frame to provide structural support while simultaneously defining the boundaries of the storage space, eliminating empty spaces between separate components and maximizing storage capacity without adding external structural complexity
Solution Approach 2:
The support frame and storage basket are merged into a single integrated structure where the frame's sidewalls serve dual functions as both structural supports and storage boundaries. This consolidation eliminates the gap between separate components and maximizes the usable storage volume within the sliding door assembly
2Force
If the sliding door and support frame are coupled with conventional connection methods, then basic support function is achieved, but the coupling force between the door and support frame is insufficient
Solution Approach 1:
The coupling bracket integrates the sliding door and support frame into a single rigid assembly by combining their connection points into one unified structural element. This merged coupling structure distributes mechanical loads across both components simultaneously, significantly increasing the overall coupling force and structural stability without requiring multiple separate connection mechanisms
Solution Approach 2:
The coupling bracket is pre-configured with attachment points and structural geometry that optimizes force distribution before the sliding door is installed. This preliminary structural arrangement ensures that when the door and frame are coupled, the maximum coupling force is achieved immediately, providing enhanced structural integrity from the outset
3Adaptability or versatility
If the storage basket operates independently, then simple operation is achieved, but the auxiliary basket cannot operate in conjunction with the main storage basket
Solution Approach 1:
The storage basket assembly is designed with universal operational characteristics where the auxiliary basket shares the same support frame, movement mechanism, and coupling interface as the main basket. This multi-functional design allows either basket to operate independently or in coordination with the other, providing operational versatility without requiring separate control mechanisms for each basket

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration expands storage space and strengthens the coupling force between the sliding door and support frame, allowing for efficient operation of the auxiliary basket in conjunction with the storage basket, thereby improving the overall storage capacity and operational stability of the refrigerator.

AI summary
In a refrigerator including a sliding door configured to open and close a storage chamber, a storage basket provided on a rear portion of the sliding door, and a support frame configured to support the sliding door and the storage basket, sidewalls of the storage basket may be formed so as to protrude outwardly except a lower portion in which the support frame is disposed between an inner case and the sidewalls, thereby increasing a storage space of the storage basket. In addition, a front protrusion, an auxiliary protrusion, and a rear protrusion are formed in an upper portion of the storage basket, and therefore a relative position of an auxiliary basket to the storage basket may be limited, and the auxiliary basket may be drawn into and out in conjunction with drawn-in and-out movements of the storage basket.
