Storage unit for cooled goods with a cooled goods holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerated storage units are cumbersome to handle, especially when loaded with goods, as they require removal of overlying items to access lower ones, making it difficult to conveniently and safely remove refrigerated goods carriers.
Innovation Solution
A storage unit with an adjustable handle element that can be used as a handle for safe removal of refrigerated goods carriers in a horizontal direction, and when moved into a second position, securely fixes the carrier in the support frame using transversely oriented stop surfaces, allowing for easy handling and secure anchoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If refrigerated goods carriers are stacked one above another in the storage unit, then storage capacity is improved, but handling difficulty increases because all overlying carriers must be removed to access lower ones
Solution Approach 1:
The support frame is divided into multiple levels with individual support contours for each carrier. Each carrier can be independently positioned and removed from its specific level without affecting others, enabling selective access to any carrier in the stack while maintaining vertical stacking for improved storage capacity.
2Ease of operation
If refrigerated goods carriers are made removable for convenient handling, then handling ease is improved, but security of fixation deteriorates
Solution Approach 1:
The handle element is designed with movable arms that can dynamically transition between a locked position (where arms engage with the support frame to secure the carrier) and an unlocked position (where arms disengage to allow removal). This dynamic mechanism enables both secure fixation during storage and convenient handling when needed.
3Ease of operation
If carriers are designed for horizontal removal, then handling ease is improved, but compatibility with vertical stacking deteriorates
Solution Approach 1:
The support frame features localized horizontal support contours at different vertical levels, each designed to accommodate carriers in a horizontal orientation. This local horizontal support structure enables carriers to be removed horizontally from their specific level while maintaining overall vertical stacking compatibility across multiple levels.

AI summary
The storage unit (2,3) has a storing chamber and a cooling good carrier that is fixed in a carrier frame (5). The cooling good carrier is extracted in horizontal direction. A grip element is moved in a position, in which it fixes the cooling good carrier in the carrier frame in form-fit manner.
