Refrigerator Door Diffuser Structure for Soft Pattern Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigerators with existing light-emitting diode (LED) lighting on the door handle fail to effectively represent patterns on the front surface under low ambient lighting and lack mood lamp functionality, making them unsuitable for enhancing aesthetics and user experience.
Innovation Solution
A refrigerator design featuring a transparent member behind the exterior member and a light-emitting member outside the transparent member, where light emitted diffuses through the transparent member and exterior patterns, creating a tranquil atmosphere and highlighting designs, especially in low-light environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If an LED light is mounted on the door handle to improve identification and aesthetics, then the ability to identify the door handle is improved, but the effectiveness in representing patterns on the front surface under low ambient lighting is insufficient
Solution Approach 1:
A transparent member with a diffusing portion is introduced as an intermediary between the light emitting member and the exterior member. This diffuser scatters the light to create soft, indirect illumination that effectively highlights patterns on the refrigerator front surface, resolving the contradiction between providing sufficient light and achieving aesthetic representation.
Solution Approach 2:
The lighting system transitions from direct point-source illumination to volumetric diffusion by incorporating a transparent member with diffusing portions. This dimensional change in light distribution creates a tranquil atmosphere and enhances pattern visibility without requiring intense direct light.
2Ease of operation
If direct light is emitted from the door handle to provide illumination, then the identification capability is improved, but direct light annoyance occurs and mood lamp functionality is not achieved
Solution Approach 1:
The transparent member with diffusing portions serves as a mediator that transforms direct light from the LED into soft, scattered illumination. This eliminates direct light annoyance while maintaining door handle identification capability and adding mood lamp functionality.
Solution Approach 2:
The diffusing portions of the transparent member create variations in light distribution and intensity, producing a tranquil atmosphere that mimics indirect lighting. This transforms the character of the light from harsh direct illumination to soft ambient glow.
3Shape
If tempered glass or plastic material is used for the exterior member to enhance color representation and texture, then the aesthetic quality is improved, but the complexity of the door structure increases
Solution Approach 1:
The transparent member with diffusing portions is nested within the door structure, positioned between the light emitting member and the exterior member. This nested arrangement integrates the lighting and diffusing functions into the existing door assembly without requiring separate external components, thereby managing structural complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution reduces direct light annoyance, provides a luxurious aesthetic by mimicking indirect lighting, and accentuates patterns, offering a refined and three-dimensional appearance that sets the refrigerator apart in terms of design.
Implementation Method 1
light emitted from the light emitting member passes through the transparent member
Implementation Method 2
light emitted from the light emitting member passes through the transparent member and through a pattern on the exterior member and diffuses to the outside

AI summary
Provided are a refrigerator and a refrigerator door. The refrigerator and refrigerator door include a transparent member provided behind an exterior member defining the exterior of the refrigerator, a light emitting member provided on an extending line of an outer end of the transparent member to radiate light toward the transparent member, and a diffusing portion formed at one side of the transparent member. Light from the light emitting member passes through the transparent member and a pattern on the exterior member to be diffused to the outside. Through this configuration producing a soft glow of light, aesthetics can be improved and opulence can be enhanced.
