Refrigerator Shelf Holding Device for Adjustable Hanging Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Household refrigeration appliances lack versatility in accommodating various sizes and types of refrigerated goods, with existing shelves often requiring adaptation or modification to support different containers, limiting their usability.
Innovation Solution
A shelf with a holding device that encloses its edge section, featuring adjustable rails with grooves and springs, allowing for the hanging storage of refrigerated goods of different widths and types without the need for special adaptation, and enabling easy insertion of commonly used carriers like baking trays or bottles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional shelves are used without additional holding devices, then the shelf structure remains simple and unmodified, but the versatility and adaptability to accommodate various sizes and types of refrigerated goods is limited
Solution Approach 1:
The holding device is divided into separate modular components: a U-shaped channel member that attaches to the shelf edge, and multiple L-shaped support members that can be independently positioned along the channel. This segmentation allows the system to adapt to various container sizes while keeping each component simple and easy to install.
Solution Approach 2:
The holding device is designed as a universal attachment system that can accommodate multiple types of refrigerated goods including bottles, baking trays, and other containers of varying dimensions. The adjustable support members within the U-shaped channel provide multi-functional capability without requiring modification to the shelf itself.
2Adaptability or versatility
If the shelf is modified to accommodate different types of containers, then the adaptability increases, but the ease of manufacture and installation decreases due to special adaptation requirements
Solution Approach 1:
The holding device is extracted as a separate attachable component rather than being integrated into the shelf structure. The U-shaped channel member attaches to the shelf edge without requiring modification to the shelf itself, and the support members can be independently installed and adjusted, simplifying both manufacture and installation.
3Adaptability or versatility
If fixed support structures are used on the shelf, then the structural stability is maintained, but the ability to accommodate different widths and types of refrigerated goods is reduced
Solution Approach 1:
The support members are designed to be movable and adjustable within the U-shaped channel, allowing dynamic repositioning to accommodate different container widths and types. This dynamic capability maintains structural stability while providing the flexibility to adapt to various storage needs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances the usability of household refrigeration appliances by allowing the storage of multiple types of refrigerated goods, including baking trays and bottles, without modifying the shelf, and accommodating different widths through adjustable rails, thereby increasing storage flexibility and efficiency.
Implementation Method 1
Each support member (17.3, 17.4) has a pair of springs (30) which, for lateral guidance of a refrigerated goods carrier (16) pushed into the rail (17.1, 17.2) in a groove base of the groove (18.1, 18.2) of the rail (17.1, 17.2) and/or on a vertical wall (32) adjoining the upper wall (19.1, 19.2) in order to press against a lateral edge of the refrigerated goods carrier (16).

AI summary
The invention relates to a household refrigeration appliance (1) comprising a thermally insulated inner container (2) having two opposing side walls (3a, 3b) that laterally define a storage space (8) for refrigerated goods, and at least one shelf (13) arranged in the storage space (8) between the two opposing side walls (3a, 3b), which forms a storage surface for the refrigerated goods, which is bounded by at least one edge section (14, 14a-14d) of the shelf (13) and comprising a holding device (15) encompassing the at least one edge section (14, 14a-14d) for the suspended storage of further refrigerated goods below the shelf (13), wherein the holding device (15) is designed to extend and store a refrigerated goods carrier (16) below the shelf (13), which can be removed from the storage space (8) and is designed to receive the further refrigerated goods, on the holding device (15).
