Solution Overview

Problem

Conventional refrigerators lack an aesthetically pleasing exterior design that provides a dynamic visual effect when viewed from different angles, leading to a dull and uninteresting appearance.

Innovation Solution

A refrigerator door design featuring a combination of a three-dimensional pattern on a transparent molded body and a two-dimensional pattern on a front glass, with the three-dimensional pattern protruding from the back surface and the two-dimensional pattern having gradations in brightness, saturation, or hue, along with an integrated LED lighting device for enhanced visual effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If a conventional solid-color door is used, then the manufacturing process is simple, but the aesthetic appearance is dull and lacks visual interest

Engineering Contradiction:
Improveaesthetic appearanceVSAvoiddoor structure complexity
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The door is divided into multiple layers: a door frame, a transparent molded body with three-dimensional patterns, and a front glass with two-dimensional patterns. This segmentation allows each layer to contribute different visual effects while maintaining manufacturing feasibility for each component

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The door combines multiple materials including transparent molded body material, glass material, and frame material to create a composite structure that achieves both aesthetic complexity and manufacturing practicality

Inventive Principle:
Principle #40Composite materials

2Shape

If a three-dimensional pattern is added to create visual depth, then the aesthetic appearance is enhanced, but the manufacturing complexity increases

Engineering Contradiction:
Improvevisual depth effectVSAvoidmolding process complexity
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

The patent transitions from two-dimensional flat door surfaces to three-dimensional patterns by forming protrusions and recesses in the transparent molded body. This dimensional change creates visual depth effects while the molding process integrates these features into the manufacturing step

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Shape

If an LED lighting device is integrated, then the visual appeal is enhanced, but the device complexity increases

Engineering Contradiction:
Improvevisual appealVSAvoiddoor assembly complexity
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The LED lighting device is merged with the door structure by integrating it into the door frame or molded body. This combination allows the lighting function to be incorporated without requiring separate mounting structures, thereby enhancing visual appeal while managing overall device complexity

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A refrigerator is provided. The refrigerator may include a refrigerator body with a storage space defined therein, a door frame rotatably coupled to the refrigerator body to open and close the storage space, a transparent molded body coupled to a front surface of the door frame, and a glass panel coupled to a front of the transparent molded body. The transparent molded body may include a three-dimensional pattern formed on a surface thereof, and the glass panel may include a two-dimensional pattern having a gradation in at least one of brightness, saturation and hue.
