Refrigerator Door Display Assembly with Modular Mounting Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing refrigerators with built-in displays face challenges in simplifying the assembling structure of the door with a display unit and achieving a sophisticated design while providing convenient functions.
Innovation Solution
A refrigerator design that includes a display unit mounted on the door with a pressing piece extending from the display case, which is fixedly connected to a fixing groove in the display unit case using a pressing member, allowing for easy assembly and integration of a communication module and proximity detection sensor behind the display glass to prevent interference with electromagnetic waves, and omitting extra trim structures for a seamless exterior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a display unit is installed on the door with traditional assembling structures, then the display can be fixed on the door, but the assembling structure becomes complex and difficult to manufacture
Solution Approach 1:
The door assembly is divided into separate modules: door body, display unit case, and display case. Each module can be manufactured independently and then assembled together, simplifying the overall structure and manufacturing process while ensuring reliable fixation of the display unit on the door.
Solution Approach 2:
The display case is nested within the display unit case, which is in turn mounted on the door. This nested arrangement allows multiple components to be integrated in a compact manner, reducing structural complexity while maintaining secure fixation of the display unit.
2Object-affected harmful factors
If communication module and proximity detection sensor are placed behind the display glass, then electromagnetic wave interference is prevented, but the assembly structure becomes more complex
Solution Approach 1:
The communication module and proximity detection sensor are extracted from the main display assembly and placed in a separate compartment behind the display glass. This extraction prevents electromagnetic wave interference with the display while keeping the component arrangement organized and manageable.
Solution Approach 2:
Instead of placing components in the horizontal plane of the display, the communication module and sensor are positioned in the depth dimension behind the display glass. This spatial reorganization prevents electromagnetic interference without significantly increasing structural complexity.
3Reliability
If extra trim structures are added for display integration, then the display can be securely mounted, but the exterior design becomes less sophisticated and seamless
Solution Approach 1:
The display case is merged with the display unit case through direct integration, eliminating the need for separate trim structures. The display case itself serves as both the mounting structure and the visible exterior, achieving a seamless and sophisticated design while maintaining secure mounting of the display unit.

AI summary
Disclosed is a refrigerator having an improved structure with a display unit. The refrigerator comprises a main body, a storeroom arranged inside the main body with an open front, a door pivotally connected to the main body for opening or closing the open front of the storeroom and a display unit installed on the door. The display unit comprises a display for displaying images, a display glass located on the front of the display to have an area larger than the display and form a touch screen, a display case with a display mounter for the display to be mounted therein, a display unit case fixedly connected to the door and a fixing unit for fixedly connecting the display case to the display unit case by pressing a part of the display case.
