Solution Overview

Problem

Refrigerators lack the ability to easily change their door design, limiting user customization and flexibility in terms of appearance and functionality.

Innovation Solution

A refrigerator design that includes a detachable door panel system, where the door panel can be easily coupled and decoupled from the door body using a combination of trims and adhesives, allowing for various designs and materials to be used, such as glass or metal, and enabling easy detachment and reattachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the door panel is fixed to the door body, then the door structure is stable and reliable, but the design cannot be easily changed

Engineering Contradiction:
Improvedesign changeabilityVSAvoiddoor structure stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The door is divided into separate components: a door body and a detachable door panel. The door panel can be removed and replaced independently from the door body, allowing design changes while maintaining the structural integrity of the door body. This segmentation enables users to change the appearance and material of the door panel without affecting the overall door structure stability.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the door panel is detachably mounted, then the design can be easily changed, but the coupling strength may be reduced

Engineering Contradiction:
Improvedesign changeabilityVSAvoidcoupling strength
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

Adhesive layers are pre-applied to the coupling surfaces of the door body and door panel. This preliminary preparation ensures that when the door panel is attached, strong bonding is achieved immediately. The pre-positioned adhesive and coupling structures ensure sufficient coupling strength for easy attachment and detachment while maintaining design flexibility.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If multiple materials are used for the door panel, then customization options are enhanced, but the manufacturing complexity increases

Engineering Contradiction:
Improvematerial customizationVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The door panel is designed as a separate, modular component that can be manufactured independently from the door body. This segmentation allows different materials (glass, metal, other materials) to be used for the door panel without complicating the overall manufacturing process. Each material type can be produced using its optimal manufacturing method, then assembled to the door body through the standardized coupling mechanism.

Inventive Principle:
Principle #1Segmentation
