Container arrangement and refrigeration device with a container arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container arrangements in refrigeration devices lack organization and accessibility for refrigerated goods, particularly ice cubes, leading to disorganization and potential slippage during use.
Innovation Solution
An insert tray with a positioning device that interacts with a receiving shape on the container's opening edge to securely fix the tray in place, combined with a box-shaped container design that includes a peripheral frame and bottom-side positioning rails to prevent slippage and optimize space, allowing for tidy organization and easy access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an insert tray is added to organize refrigerated goods, then organization and accessibility are improved, but device complexity increases
Solution Approach 1:
The insert tray is nested within the container, with the tray positioned inside the box-shaped container. The positioning device on the tray interacts with the receiving shape on the container's opening edge, creating a nested configuration that organizes refrigerated goods while maintaining a compact structure.
Solution Approach 2:
The container arrangement is segmented into distinct components: the box-shaped container and the separate insert tray. This segmentation allows the tray to be independently positioned and removed, providing organization for refrigerated goods without permanently complicating the overall container structure.
2Reliability
If a positioning device is used to fix the tray, then stability is improved, but manufacturing complexity increases
Solution Approach 1:
Instead of attaching complex fixation mechanisms to the tray, the solution inverts the approach by providing a receiving shape on the stationary container structure and a simple positioning device on the movable tray. The positioning device engages with the receiving shape to provide form-locking connection, stabilizing the tray without requiring complex manufacturing on the tray itself.
Solution Approach 2:
The positioning device is designed as a simple, easily manufactured component with minimal structural requirements. The form-locking connection through the bar and receiving shape creates a reliable yet simple solution that can be produced cost-effectively without delicate or damage-prone projections.
3Loss of energy
If the container uses a mesh design for airflow, then cooling efficiency is improved, but structural strength decreases
Solution Approach 1:
The container is segmented into the mesh walls for airflow and the separate frame structure for strength. The frame is attached at the opening edge to provide structural support, while the mesh portions allow cold air distribution. This segmentation enables both mesh design for cooling efficiency and frame structure for structural strength.

AI summary
A container arrangement for use in an interior (2) of a refrigeration device (1) includes a box-shaped container (40) with a bottom part (41) surrounded or enclosed by peripheral side walls (42) and with a loading opening (46) with an opening edge (43) defining a free end of the side walls (42), and an insert tray (50) for positioning in the container (40). The opening edge (43) includes a receiving shape (45) which interacts with a corresponding positioning device (55) on the tray (50) to define a predetermined inserted position of the insert tray (50) relative to the opening (46). The container arrangement (4) is configured for being pushed into and pulled out of the interior (2).
