Solution Overview

Problem

The existing designs of automatic ice-making machines in refrigerators face challenges with inconvenient mounting, maintenance, and cleaning due to limited space surrounding the ice-making machine when it is mounted on the inner wall of the ice-making chamber.

Innovation Solution

The ice-making machine is mounted on the ice-making chamber door, allowing for unobstructed access and space when the door is opened, facilitating easy mounting, maintenance, and cleaning, with additional features like an ice storage box below and positioning projections to ensure stability and secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the ice-making machine is mounted on the inner wall of the ice-making chamber, then the refrigerator can achieve automatic ice-making functionality, but the space surrounding the ice-making machine is limited, making cleaning and maintenance inconvenient

Engineering Contradiction:
Improveautomatic ice-making functionalityVSAvoidconvenience of cleaning and maintenance
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The ice-making chamber door is designed to be movable, allowing the ice-making machine to be accessed by opening the door. This dynamic configuration enables convenient cleaning and maintenance while maintaining automatic ice-making functionality when the door is closed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The ice-making machine is extracted from the fixed inner wall mounting and relocated to the door structure. This extraction allows the machine to be easily accessible by opening the door, solving the cleaning and maintenance accessibility problem while preserving the automatic ice-making capability.

Inventive Principle:
Principle #2Taking out (Extraction)

2Device complexity

If the ice-making machine is mounted on the inner wall of the ice-making chamber, then the refrigerator structure is compact, but the ice-making machine is difficult to access for mounting and maintenance due to occlusion by chamber walls

Engineering Contradiction:
Improvecompact refrigerator structureVSAvoidaccessibility for mounting and maintenance
Core Design Contradiction:
Device complexityVSEase of repair

Solution Approach 1:

By making the door movable rather than fixed, the design enables easy access to the ice-making machine for mounting and maintenance while keeping the overall refrigerator structure compact. The dynamic door configuration resolves the accessibility issue without compromising structural compactness.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The door acts as an intermediary structure that houses the ice-making machine and provides access control. This intermediary design allows the machine to be protected within the compact structure while enabling easy access through door opening, solving both compactness and accessibility requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If the ice-making machine is mounted on the door, then the space available for mounting and maintenance is significantly increased, but additional structural components are required

Engineering Contradiction:
Improvespace availability for mounting and maintenanceVSAvoiddoor structure requirements
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The door structure serves multiple functions: it provides access to the ice-making machine, houses the machine during operation, and enables easy cleaning and maintenance. This multi-functionality increases space availability for operations while minimizing additional structural complexity by utilizing the door's inherent versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The ice-making machine is merged with the door structure, combining the access function, housing function, and operational space into a single integrated component. This merging eliminates the need for separate access mechanisms and reduces overall structural complexity while maximizing space availability for mounting and maintenance.

Inventive Principle:
Principle #5Merging (Combining)
