Solution Overview

Problem

Current refrigerator designs do not allow for easy replacement of door panels, which can lead to maintenance and aesthetic issues over time.

Innovation Solution

The refrigerator features a door panel that is detachably coupled to the door body using first and second fixers, allowing for easy mounting and removal, with a buffer member to absorb shocks and noise, and a variety of designs for the panel body to meet user needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the door panel is made as a single integrated structure with the door body, then the structural strength is improved, but the ease of repair and replacement deteriorates

Engineering Contradiction:
Improvestructural strengthVSAvoidease of panel replacement
Core Design Contradiction:
StrengthVSEase of repair

Solution Approach 1:

The door assembly is divided into separate components: the door body and the door panel are detachably connected through fixing structures. This allows the panel to be replaced independently without replacing the entire door assembly, resolving the contradiction between structural strength and ease of repair.

Inventive Principle:
Principle #1Segmentation

2Ease of repair

If the door panel is made detachable for easy replacement, then the ease of repair is improved, but the structural strength deteriorates

Engineering Contradiction:
Improveease of panel replacementVSAvoidstructural strength
Core Design Contradiction:
Ease of repairVSStrength

Solution Approach 1:

Fixing structures such as recesses and protrusions are pre-designed and pre-positioned on the door body and panel respectively. These preliminary structural features ensure that when the panel is reattached, it achieves proper alignment and structural strength without requiring complex assembly procedures, thus maintaining both ease of repair and structural integrity.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If multiple fixing structures are used to secure the panel, then the reliability is improved, but the device complexity increases

Engineering Contradiction:
Improvepanel attachment reliabilityVSAvoidfixing structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The fixing structures are designed as integrated features of the door body and panel themselves (recesses, protrusions, clips) rather than separate fastening components. This extraction of the fastening function into the structural elements themselves maintains reliability while avoiding the complexity of additional separate fixing mechanisms.

Inventive Principle:
Principle #2Taking out (Extraction)
