Refrigerator Shelf Support With Removable Bottle Bracket Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerated goods carriers for household refrigeration appliances have pivoting bracket structures that are difficult to remove and store efficiently, as they require emptying the appliance and risk damage, making them operationally unreliable and inflexible.
Innovation Solution
A refrigerated goods carrier with stub axles featuring a protruding element at the distal end to prevent axle escape under load, and adapters with multiple attachment points for different bottle formats, allowing easy adaptation and secure bracket positioning using fixed and elastic hooks, ensuring operational reliability and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bracket structure is designed to be removable from the refrigerated goods carrier, then the adaptability and storage flexibility are improved, but the device complexity and risk of damage increase
Solution Approach 1:
The bracket structure is divided into separate components: the bracket body, the axle journal, and the retaining element. This segmentation allows the bracket to be easily attached and detached from the refrigerated goods carrier while minimizing the risk of damage during removal and storage.
Solution Approach 2:
The bracket can be completely removed from the refrigerated goods carrier when not in use, allowing for flexible storage arrangements and adaptation to different storage needs. The extraction feature enables users to store brackets outside the refrigerator or in alternative locations.
2Ease of manufacture
If the stub axle is designed without additional retaining elements, then the manufacturing simplicity is improved, but the reliability of the bracket connection deteriorates under load
Solution Approach 1:
Instead of making the entire axle more complex, a simple retaining element (such as a bent wire or clip) is added locally at the distal end of the stub axle. This local modification prevents the axle from escaping its bearing under load while maintaining the overall simplicity of the manufacturing process.
3Adaptability or versatility
If multiple attachment points are provided for adapters, then the adaptability to different bottle formats is improved, but the device complexity increases
Solution Approach 1:
The adapter system is designed with multiple attachment points on the bar that can accommodate different bottle formats and sizes. The same basic adapter structure can be attached at different locations along the bar, providing universal adaptability without requiring multiple different adapter designs.

AI summary
A support for refrigerated products in a refrigeration appliance, in particular a domestic refrigeration appliance, comprises a plate (1), strips (3) that extend in the direction of the depth of the plate and border lateral edges of the plate, and at least one bow that is pivotably retained below the plate, within bearings (11) arranged on the strips.
