Solution Overview

Problem

Existing refrigerators with automatic ice making and crushing functions waste internal space and require the door to be opened to access ice cubes, making operation inconvenient.

Innovation Solution

A refrigerator design with a mounting bracket on the door inner surface that integrates the ice making assembly closer to the door, reducing internal space usage and featuring a wiring groove for electrical components, allowing direct ice access without opening the door through an ice outlet passage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If ice making components are installed inside the refrigerator compartment, then ice making function is achieved, but refrigerator internal space is wasted

Engineering Contradiction:
Improveice making functionVSAvoidrefrigerator internal space
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The ice making assembly is extracted from the refrigerator compartment and installed on the refrigerator door instead. The mounting bracket is fixed on the door inner surface, positioning the ice making components outside the main storage space, thereby recovering internal volume while maintaining the ice making capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The ice making function is relocated from the three-dimensional internal space to the two-dimensional door surface. By utilizing the door as a mounting platform, the system transforms the spatial arrangement, moving the ice making assembly to a different dimensional plane that does not encroach on storage volume.

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

2Adaptability or versatility

If ice cubes are stored in the refrigerator, then ice making function is completed, but door must be opened to access ice which is inconvenient

Engineering Contradiction:
Improveice making functionVSAvoidice access convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The ice outlet passage extracts the ice delivery function from the internal storage location and connects it directly to the door exterior. This allows ice to be dispensed outside the refrigerator compartment, enabling users to access ice without opening the door, thus improving operational convenience.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The ice outlet passage acts as an intermediary channel between the ice making assembly and the external environment. It transports ice cubes from the enclosed making chamber to the outside world, facilitating direct access while maintaining the sealed refrigerator compartment.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Volume of stationary object

If ice making assembly is moved closer to door, then space usage is optimized, but wiring management becomes more complex

Engineering Contradiction:
Improverefrigerator internal spaceVSAvoidwiring management
Core Design Contradiction:
Volume of stationary objectVSDevice complexity

Solution Approach 1:

The mounting bracket is designed with multi-functionality: it not only secures the ice making assembly to the door but also incorporates integrated wiring channels and electrical component mounting areas. This consolidation handles both mechanical support and electrical routing in a single structure, managing complexity rather than increasing it.

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

Solution Approach 2:

The mounting bracket merges the support structure, wiring pathway, and electrical component housing into a unified assembly. By combining these previously separate functions into one integrated element, the design simplifies the overall system architecture and reduces the number of discrete components that would otherwise complicate wiring management.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A refrigerator having an ice making function, comprising a refrigerator door (1); an inner surface (11) of the refrigerator door (1) is fixedly provided thereon with a mounting support (2), and the mounting support (2) is configured to mount an ice making assembly (3). The mounting support (2) comprises a first surface (21) that faces the refrigerator door (1) and a second surface (22) that is opposite to the first surface (21); the second surface (22) comprises a mounting area (221) used for mounting the ice making assembly (3) as well as an edge area (222) provided at the periphery of the mounting area (221). A wiring groove (211) is formed at the edge area (222) of the mounting support (2), and the wiring groove (211) is recessed in the direction from the first surface (21) toward the second surface (22); and/or the wiring groove (211) is formed at a position corresponding to the edge of the mounting support (2) on the inner surface (11) of the refrigerator door (1), and the wiring groove (211) is recessed in the direction from the inner surface (11) of the refrigerator door (1) toward an outer surface of the refrigerator door (1). Thus, the ice making assembly (3) is disposed closer to the refrigerator door (1), further reducing the space which the ice making assembly (3) occupies as the interior of the refrigerator.
