Door body for refrigerator and assembly method therefor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerator glass doors are limited in displaying large screens due to the need for a border with a glue distance of at least 20 mm, restricting the display range 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 with minimal or no borders on the sides, achieved through a specific assembly method involving foaming and gluing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a border with glue distance of at least 20 mm is reserved for attaching display screen, then the display screen can be stably attached, but the display range is limited and large-screen display cannot be achieved
Solution Approach 1:
The door body is divided into multiple components: panel, display screen, bracket, inner door lining, outer door lining, and trim strip group. The bracket is further segmented into support ribs that provide distributed support points. This segmentation allows the display screen to be supported at multiple locations without requiring large border areas, enabling full-screen or near-full-screen display while maintaining stable attachment.
Solution Approach 2:
A bracket is introduced as an intermediary component between the display screen and the door body structure. The bracket transfers the load and provides support without requiring direct gluing of the display screen to the panel with large borders. This intermediary structure enables the display screen to be attached with minimal or no borders while maintaining attachment stability.
2Ease of manufacture
If display screen is attached directly to panel with large borders, then attachment is simple, but the display effect is affected due to limited display range
Solution Approach 1:
The bracket serves as an intermediary that simplifies the attachment process while enabling larger display areas. Instead of directly gluing the display screen to the panel (which would require large borders), the bracket provides a structured support system that can be easily assembled and provides stable mounting for the display screen with minimal borders.
Solution Approach 2:
The support structure is segmented into multiple support ribs within the bracket, providing distributed attachment points. This segmentation allows the display screen to be supported effectively without requiring large border areas, maintaining both ease of manufacture and large display area.
3Area of moving object
If minimal or no borders are used for display screen, then large-screen display effect is achieved, but the structural reliability of mounting may be compromised
Solution Approach 1:
The bracket is divided into multiple support ribs that provide distributed support points across the door body. This segmentation allows the display screen to be mounted with minimal or no borders while maintaining mounting reliability through multiple contact points that distribute the mechanical load.
Solution Approach 2:
The support structure extends into the third dimension by creating a bracket that protrudes from the door body surface. This dimensional change allows the display screen to be supported from behind without requiring large border areas on the front surface, maintaining both large display area and mounting reliability.

AI summary
A door (120) of a refrigerator, comprising: a panel (200) having a main body (201) that constitutes a front end of the door (120), a left side (202) and a right side (203); a display screen (300) disposed behind the panel (200) and having, corresponding to the structure of the panel (200), a main body (301), a left side (302) and a right side (303); a main control board (500) for controlling the display screen (300); a bracket (400) disposed behind the display screen (300) to provide support for the display screen (300); an inner door lining (600) disposed behind the bracket (400) to provide support for the bracket (400); an outer door lining (800) disposed behind the inner door lining (600) to constitute a rear end of the door (120); and a trim strip group (700), with a foaming space being confined between the inner door lining (600), the outer door lining (800) and the trim strip group (700). The door of a refrigerator of the present invention achieves a large-screen display effect with no borders or narrow borders on the left and right sides.
