Refrigerator Ice-Maker Layout Using Guided Cold Air
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerators require users to bend to access ice makers located in freezing compartments, which can be inconvenient, especially for shorter individuals, and rearranging the compartments to address this issue increases manufacturing costs and complexity.
Innovation Solution
Incorporating an ice making compartment within the refrigerating compartment and using a cold air guiding device to direct cold air from the heat exchanger to the ice making compartment, allowing for ice production without altering the refrigerator's capacity or freezing compartment layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ice maker is arranged in the freezing compartment, then ice can be made using cold air from the heat exchanger, but users must bend to access the ice maker which is inconvenient
Solution Approach 1:
The ice maker is extracted from the freezing compartment and relocated to the refrigerating compartment door, allowing users to access ice at a convenient height without bending, while maintaining the freezing compartment's original layout and avoiding increased device complexity
Solution Approach 2:
A cold air guiding device acts as an intermediary to transport cold air from the heat exchanger in the freezing compartment to the ice maker in the refrigerating compartment door, enabling ice production without direct thermal connection between the two compartments
2Ease of operation
If the freezing compartment is arranged over the refrigerating compartment to improve ice accessibility, then ice access becomes easier, but manufacturing costs and complexity increase
Solution Approach 1:
The ice maker function is extracted from the freezing compartment and placed in the refrigerating compartment door, eliminating the need to rearrange compartment positions while achieving easy ice access and maintaining manufacturing simplicity
Solution Approach 2:
Instead of changing the vertical arrangement of compartments (overhead freezing compartment), the solution moves the ice maker to a different spatial dimension - the door structure of the refrigerating compartment - achieving the same accessibility goal without structural reconfiguration
3Ease of operation
If the ice maker is placed outside the freezing compartment, then ice accessibility improves, but manufacturing costs increase due to additional heat exchanger installation
Solution Approach 1:
The heat exchanger in the freezing compartment serves dual functions: cooling the freezing compartment and providing cold air to the ice maker through the cold air guiding device, eliminating the need for a separate ice-making heat exchanger and reducing manufacturing costs
Solution Approach 2:
The cold air guiding device serves as an intermediary that efficiently transports cold air from the existing heat exchanger to the ice maker, enabling external ice maker placement without requiring additional heating or cooling components

AI summary
A refrigerator is disclosed which enables the user to easily take ice out of an ice maker without causing a variation in the capacity of the refrigerator or a limitation on the position of a freezing compartment. The refrigerator includes a refrigerator body which includes a freezing compartment and a refrigerating compartment, an ice making compartment which is arranged in the refrigerating compartment, to make ice, a heat exchanger which generates cold air for freezing food storing stored in the freezing compartment, and a cold air guiding device which guides the cold air generated by the heat exchanger to the ice making compartment, to enable the ice making compartment to make ice.
