Refrigerator Rack with Pivoting Frame for Stable Bottle Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerator racks are unstable and inconvenient to use, particularly when trying to place bottled liquids in a tilted position to prevent liquid flow, as they often require an unstable foldable structure that complicates horizontal and tilted placement.
Innovation Solution
A rack design featuring a first and second support frame that can pivot between positions to accommodate bottles in both lying and tilted states, allowing for efficient space utilization and secure placement without affecting horizontal positioning, using a revolving shaft and positioning apparatus for stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a foldable rack with a revolving shaft is used to enable tilted placement, then tilted and horizontal placement functions are achieved, but the structure becomes unstable and operation becomes inconvenient
Solution Approach 1:
The rack is divided into a fixed support frame and a movable support frame that can pivot independently. The movable support frame is segmented into a support panel and a support leg, allowing the panel to rotate between horizontal and tilted positions while the leg remains stable, thus achieving versatility without compromising structural stability.
Solution Approach 2:
The tilting function is extracted from the entire rack structure and assigned specifically to the movable support frame. This allows the fixed support frame to maintain stability while only the necessary component (movable frame) performs the tilting operation, improving both reliability and ease of operation.
2Adaptability or versatility
If the second support frame is positioned to support tilted bottles, then tilted placement is enabled, but space utilization decreases and aesthetics are compromised
Solution Approach 1:
The movable support frame is designed to pivot dynamically between a horizontal position (when bottles are stored lying down) and a tilted position (when bottles need to be displayed tilted). When in the horizontal position, the support panel aligns with the fixed support frame, maximizing space utilization and maintaining aesthetics. When tilted, it provides the necessary angled support without requiring a permanently larger structure.
Solution Approach 2:
The support panel rotates from a two-dimensional horizontal plane to a three-dimensional tilted orientation, allowing the same physical space to serve dual purposes. This dimensional transformation enables tilted bottle placement without permanently occupying additional space, as the panel returns to its original plane when not in use.
3Adaptability or versatility
If a directly tilted rack surface is used, then tilted placement is achieved, but horizontal placement becomes inconvenient
Solution Approach 1:
The movable support frame with its pivotable support panel allows users to dynamically adjust between horizontal and tilted positions based on their needs. When horizontal placement is required, the panel is simply positioned horizontally, providing a flat, convenient surface. When tilted placement is needed, the panel rotates to the tilted position. This dynamic adjustment is much easier than trying to use a permanently tilted surface for horizontal storage.

AI summary
A rack is provided for a refrigeration appliance. The rack includes a first support frame and a second support frame. The second support frame can move between a first position and a second position, and when the second support frame is at the first position, the first support frame and the second support frame form an accommodating portion extending from the first support frame to the second support frame and adapted to accommodating a bottle body in a lying state. When the second support frame moves to the second position, the second support frame supports a bottle neck located above the first support frame and is adapted to support the bottle body with a supporting portion supporting the bottle body in a tilted state.
