Door of refrigerator and assembly method thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerator glass doors are limited in display range due to a required border distance of at least 20 mm, preventing large-screen displays and affecting the display effect.
Innovation Solution
A refrigerator door design featuring a panel with a display screen supported by a bracket and inner/outer door linings, along with a trim strip group, allowing for a large-screen display without borders on the sides, achieved through a specific assembly method involving foaming and gluing of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a border with glue distance of at least 20 mm is reserved, then the display screen can be stably attached to the glass door, but the display range on the left and right sides is limited and large-screen display cannot be achieved
Solution Approach 1:
The patent transitions from attaching the display screen directly to the glass door surface (2D attachment) to embedding it within a recessed cavity structure (3D spatial arrangement). By creating a recessed area in the glass door and forming a foam filling layer within this cavity, the display screen can extend to the edges of the glass door without requiring large border distances for attachment, thus achieving full-area or near full-area display while maintaining stable installation.
2Area of moving object
If the display screen is embedded without borders, then large-screen display effect is achieved, but the structural support and stability become more difficult to ensure
Solution Approach 1:
The patent applies beforehand cushioning by pre-forming a foam filling layer within the recessed cavity before installing the display screen. This foam layer serves as a cushioning and buffering medium that provides mechanical support, absorbs stress, and ensures stable positioning of the display screen. The foam material compensates for any gaps or irregularities, maintaining reliable contact and support across the entire display area without requiring traditional border attachments.
Solution Approach 2:
The patent employs composite materials by combining the glass door structure with a foam filling layer and metallic or plastic support frames. The foam material (likely a polymer foam) provides lightweight structural support and cushioning, while the glass door provides the rigid outer structure. This composite approach distributes mechanical loads effectively across the entire assembly, ensuring stability and reliability of the borderless display screen without compromising the strength of the glass door.
3Area of moving object
If the display screen occupies the full area of the glass door, then the display effect is enhanced, but the heat dissipation becomes more difficult
Solution Approach 1:
The patent introduces an intermediary heat dissipation system by incorporating ventilation openings or heat dissipation channels within the recessed cavity structure or the support frame. This intermediary structure acts as a thermal management system that facilitates air circulation behind the display screen, carrying heat away from the display components. The foam filling layer may also serve as a thermal insulation barrier, directing heat flow toward designated dissipation paths rather than allowing uniform heat distribution throughout the glass door, thus improving overall heat dissipation efficiency for the full-area display.

AI summary
A door of a refrigerator, comprising: a panel having a main body, a left side and a right side; a display screen disposed behind the panel and having, corresponding to the structure of the panel, a main body, a left side and a right side; a main control board for controlling the display screen; a bracket disposed behind the display screen to provide support for the display screen; an inner door lining disposed behind the bracket to provide support for the bracket; an outer door lining disposed behind the inner door lining; and a trim strip group, with a foaming space being confined among the inner door lining, the outer door lining and the trim strip group.
