Refrigerator Door Display Assembly for Touch and Wireless Integration
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 on the door with a touch screen feature, a display case fixedly connected to the door frame using a pressing piece and fixing unit, and a proximity detection sensor to activate the display upon user approach, allowing for easy assembly and integration of communication modules without interference from the metal door frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display unit is installed on the door of the refrigerator, then user convenience and functionality are improved, but the assembling structure becomes more complex
Solution Approach 1:
The display unit is divided into separate components: display case, display unit case, pressing piece, and fixing unit. These segmented parts can be assembled independently and then combined, simplifying the overall assembly process while maintaining full functionality.
Solution Approach 2:
The display case is nested within the display unit case, with the pressing piece extending from the display case into the display unit case. This nested arrangement allows multiple components to be integrated in a compact manner, reducing assembly complexity while preserving all functions.
2Shape
If a display unit is built into the door, then the design becomes more sophisticated, but the assembly process becomes more difficult
Solution Approach 1:
The pressing piece is pre-formed on the display case before assembly. This preliminary preparation allows for easier integration during the final assembly step, as the pressing action is already built into the component structure rather than requiring separate assembly operations.
Solution Approach 2:
The fixing unit utilizes the pressing piece's inherent pressing action to achieve self-fixing. When the display unit case is positioned, the pressing piece automatically presses against the fixing groove, creating a self-assembling mechanism that simplifies the overall assembly process while maintaining a sophisticated integrated design.
3Adaptability or versatility
If communication modules are integrated into the display unit, then remote control capabilities are enhanced, but electromagnetic wave transmission may be interfered with by the metal door frame
Solution Approach 1:
The display glass acts as an intermediary between the communication modules and the external environment. It allows electromagnetic waves to pass through while providing physical protection and integration within the display unit structure, enabling communication functionality without direct exposure to the metal door frame's interference.
Solution Approach 2:
The display glass is specifically positioned in the display unit to create a localized transmission path for electromagnetic waves. This local quality enhancement allows communication modules to function effectively by providing a dedicated pathway that minimizes interference from the surrounding metal structure.

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.
