Movable Refrigerator Door Column Design for Bidirectional Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile refrigerators have doors that can only be opened on one side, causing inconvenience in narrow environments, and existing solutions for bidirectional opening are complex or rely on intricate mechanics.
Innovation Solution
A movable refrigerator design featuring door columns on both sides of the body, with mounting and accommodating grooves and arc-shaped limiting protrusions, allowing the door to be easily rotated and opened bidirectionally, facilitated by bolts and an elastic door buckle for convenient installation and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a door shaft or door column is provided on only one side of the refrigerator body, then the structure is simple, but the door can only be opened to one side causing inconvenience in narrow environments
Solution Approach 1:
The refrigerator body is divided into four corners with door frames, and door columns are segmented and fixed at each corner. This segmentation allows selective installation of door columns on different sides of the refrigerator body, enabling bidirectional door opening while maintaining structural simplicity.
Solution Approach 2:
The door connection system is made detachable and reconfigurable. Door columns can be removed and reinstalled on different sides of the refrigerator body, allowing the door opening direction to be dynamically changed according to usage requirements rather than being fixed.
2Adaptability or versatility
If complex mechanics with hooks and push rods are used on each side of the door, then bidirectional door opening is achieved, but the structure becomes complex and difficult to assemble
Solution Approach 1:
The complex push rod mechanism and hooks are extracted and replaced with simple door columns fixed at the door frames. The door columns work in conjunction with mounting grooves and limiting protrusions to achieve bidirectional door opening without requiring intricate mechanical components.
Solution Approach 2:
Mounting grooves and limiting protrusions are introduced as intermediary elements between the door columns and the door. These simple geometric features enable the door to be securely attached and detached from different sides without complex mechanics.
3Adaptability or versatility
If differently sized rod portions or retaining portions are used to provide bidirectional opening, then door opening flexibility is achieved, but the structure becomes asymmetric and more complex
Solution Approach 1:
While the door columns themselves are symmetric, the mounting grooves and limiting protrusions are positioned asymmetrically on different sides of the door. This asymmetric arrangement of connection features enables bidirectional opening while keeping the door column structure simple and uniform.

AI summary
Provided is a movable refrigerator allowing bidirectional door opening. The refrigerator comprises a refrigerator body and a refrigerator door, wherein the refrigerator door is detachably connected to the refrigerator body; door frames are provided at four corners of the refrigerator body, and convex door columns are fixedly provided at the door frames; mounting grooves are provided at two ends of one side of the refrigerator door, and accommodaitng grooves are provided at two ends of the corresponding side; and limiting protrusions are provided in the mounting grooves, and the door columns are clamped between the mounting grooves and the limiting protrusions, so that the refrigerator body and the refrigerator door are rotatably connected, and the door columns on the opposite sides are accommodated in the accommodating grooves. By providing the door columns on the front side and the rear side of the refrigerator body and also providing the mounting grooves and the accommodating grooves on the refrigerator door, the refrigerator door can be mounted on any lateral surface on the front side or the rear side, it is easy to detach the refrigerator door from the refrigerator body, and a user can change the opening direction of the refrigerator door at any time, thereby overcoming the defect of one-side door opening.
