Solution Overview

Problem

Existing refrigerator display units are inconveniently separated from the door, requiring additional components and potentially damaging the door's front side.

Innovation Solution

A display unit is designed to be solidly mounted and easily separable from the door, featuring a display case with a concave structure and coupling protrusions that allow for rotation and secure mounting, preventing insertion and separation damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the display unit is separated from the door using an additional separation unit, then the display unit can be removed, but additional components are required and the front side of the door is damaged

Engineering Contradiction:

Improvedisplay unit removalVSAvoidadditional components

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The separation function is merged into the display unit's own structure through the protrusion and groove mechanism. The display unit includes a protrusion that engages with a groove in the door, allowing the display unit to serve both as the mounted component and the separation mechanism, eliminating the need for separate separation units

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The separation functionality is extracted from the door structure and integrated into the display unit itself. Instead of having the door provide separation features, the display unit contains its own protrusion that interfaces with the door's groove, transferring the separation capability to the removable component

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If the display unit is separated from the door using an additional separation unit, then the display unit can be removed, but the front side of the door is damaged

Engineering Contradiction:

Improvedisplay unit removalVSAvoiddoor damage

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The potential harm of damage is converted into a beneficial non-contact separation mechanism. The protrusion-groove design allows the display unit to be removed by simple displacement without requiring forceful actions that would damage the door's front side, transforming what could be a damaging separation process into a gentle, controlled movement

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Stability of the object's composition

If the display unit is solidly mounted on the door, then the mounting is secure, but the display unit cannot be easily separated

Engineering Contradiction:

Improvemounting securityVSAvoiddisplay unit separation

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The mounting system transitions from a static fixed state to a dynamic removable state through the protrusion-groove mechanism. The display unit is securely mounted when engaged, but can be easily separated by displacing the protrusion from the groove, allowing the system to switch between stable and removable states as needed

Inventive Principle:

Principle #15Dynamics

AI summary

A refrigerator includes a body having a storage compartment, a door that opens and closes the storage compartment, and a display unit separably provided on a front side of the door. If one side of the display unit is inserted into an inner side of the front side of the door due to rotation, the other side of the display unit is provided to protrude toward a front of the door. With this configuration, the display unit can be easily separated from the door.
