Refrigerator Panel Assembly with Back Cover Support to Prevent Sagging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerators require complete removal and replacement of decoration panels to change the outer appearance, leading to potential sagging and damage due to added components and repeated impacts.
Innovation Solution
A detachable panel assembly for refrigerators with a load-supporting structure using a back cover, including a metal back cover and brackets to secure the panel, allowing color-changing lighting without disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a reflective layer and transparent panel are added to enable color-changing lighting, then the outer appearance can be customized, but the door panel becomes heavy and may sag
Solution Approach 1:
The door assembly is segmented into multiple components: door body, panel assembly (with transparent panel and lighting device), and back cover. This segmentation allows the heavy panel assembly to be supported independently by the back cover structure, preventing the entire door from becoming excessively heavy while still enabling outer appearance customization through the transparent panel with lighting.
2Adaptability or versatility
If components are added to enable color-changing lighting, then the outer appearance can be customized, but the door panel may sag due to added weight
Solution Approach 1:
The back cover acts as an intermediary structure between the door body and the panel assembly. It provides additional support points and load distribution, serving as a mediator that prevents the panel assembly from sagging while still allowing the transparent panel to display customized outer appearances through lighting.
3Ease of operation
If the door is frequently opened and closed, then the door remains functional, but the panel assembly may sag or be damaged by repeated impact
Solution Approach 1:
The back cover with its extended support structure provides beforehand cushioning and reinforcement to the panel assembly. This pre-established support system absorbs and distributes the repeated impact forces generated during frequent door opening and closing operations, preventing sagging and damage before they occur.
4Ease of repair
If a detachable panel assembly is used, then maintenance becomes easier, but the mounting structure must be firm to prevent sagging
Solution Approach 1:
The detachable panel assembly is segmented into removable components (panel, lighting device, back cover) that can be easily maintained or replaced. The mounting structure uses the back cover's extended support portions to provide firm attachment points to the door body, ensuring that the detachable design does not compromise mounting strength and prevent sagging.

AI summary
An appliance includes a cabinet in which a storage space is defined and a door configured to open and close the storage space. The door includes a door body and a panel assembly mounted on the door body. The panel assembly includes a panel that defines a front surface of the door and is configured to transmit light, a lighting device configured to allow the panel to shine with a set color, and a back cover configured to define a rear surface of the panel assembly. A cover support portion of which at least a portion extends backward to be supported on the door body is disposed on a lower end of the back cover.
