Solution Overview

Problem

The installation of an icemaker in a refrigerator's door compartment often results in water overflow when the door is opened and closed, leading to damage and reduced storage space, and existing solutions like water overflowing preventing covers hinder the icemaker's rotation.

Innovation Solution

An icemaker with a rotating tray and a water overflowing preventing member disposed around or adjacent to the tray, which rotates with the tray to prevent water overflow and is designed to return to its initial position by self-gravity, allowing for seamless door operation and ice discharge.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the icemaker is installed in the door of the freezing compartment, then the storing space is sufficiently secured, but water stored in a tray may overflow when the door is opened and closed

Engineering Contradiction:
Improvestoring spaceVSAvoidwater overflow
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The water overflowing preventing member is designed to rotate together with the tray, changing from a static cover to a dynamic component that moves with the tray during door opening/closing operations, preventing water overflow while allowing tray rotation

Inventive Principle:
Principle #15Dynamics

2Object-affected harmful factors

If a water overflowing preventing cover is installed on the icemaker, then water overflow is prevented, but it is difficult to rotate the icemaker as the icemaker trips over the cover

Engineering Contradiction:
Improvewater overflow preventionVSAvoidtray rotation
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The water overflowing preventing member is configured to rotate together with the tray, transforming from a fixed obstacle to a moving component that follows the tray's rotation, thereby eliminating interference with tray rotation while maintaining water overflow prevention

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The water overflowing preventing member is integrated with the tray rotation mechanism, combining the water prevention function with the rotation motion, allowing both functions to coexist without interference

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If the icemaker is installed in the freezing compartment, then the icemaker structure is simple, but the storing space of the freezing compartment is reduced by the space occupied by the icemaker

Engineering Contradiction:
Improveicemaker structureVSAvoidstoring space
Core Design Contradiction:
Device complexityVSArea of stationary object

Solution Approach 1:

The icemaker is relocated from the freezing compartment interior to the door, utilizing the door space dimension, thereby preserving the freezing compartment's storing space while maintaining the icemaker's functionality with the added benefit of door opening/closing driven rotation

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