Pivotable Refrigerator Shelf for Space-Saving Storage Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerator shelf systems are complex to install and remove, requiring separate storage and often involving slidable mechanisms that are costly and difficult to manage.
Innovation Solution
A pivotable shelf system where the shelf is supported by a holder guided along the side edge of an intermediate floor, allowing the shelf to be easily extended in length without protruding above the floor, with a guide mechanism that includes a support element with a guide groove and projection for space-saving folding and locking, and U-shaped support rails for protection and easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a slidable mechanism is used to extend the shelf, then the storage space can be increased, but the device complexity and manufacturing cost increase
Solution Approach 1:
The shelf is designed to be pivotable between a folded position (parallel to intermediate floor) and an unfolded position (below intermediate floor), transforming a static structure into a dynamic one that adapts storage capacity based on need without complex slidable mechanisms
Solution Approach 2:
The shelf system is divided into separate components: the intermediate floor, the shelf, and the holder with pivot mechanism, allowing independent assembly and simplifying the overall structure while maintaining functionality
2Volume of moving object
If the shelf is made larger to increase storage area, then more goods can be stored, but the shelf protrudes above the intermediate floor when folded
Solution Approach 1:
The shelf extension is achieved by utilizing the vertical dimension through pivoting motion, allowing the shelf to extend below the intermediate floor rather than protruding above it, thus increasing storage area without increasing the horizontal footprint when folded
3Ease of operation
If the holder is not guided along the side edge, then the structure is simpler, but the shelf cannot be pushed backwards in a space-saving manner
Solution Approach 1:
The guide groove acts as an intermediary element between the holder and the intermediate floor, providing guided motion that enables space-saving positioning while keeping the overall structure simple and easy to manufacture
