Refrigerator Ice-Making Compartment Layout for Easier Ice Access
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 position.
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, but users must bend to access it which is inconvenient
Solution Approach 1:
The ice making compartment is moved from the freezing compartment to the refrigerating compartment, utilizing the vertical space above the freezing compartment. This dimensional repositioning allows users to access ice at a higher, more convenient level without bending, while the cold air guiding device ensures proper cooling functionality is maintained.
2Ease of operation
If the freezing compartment is rearranged to improve ice accessibility, then user convenience improves, but manufacturing costs and complexity increase
Solution Approach 1:
The refrigerator is segmented into distinct functional zones: the freezing compartment remains dedicated to freezing operations, while the refrigerating compartment is segmented to include a separate ice making compartment. This segmentation allows independent optimization of each zone without requiring complex rearrangement of the entire refrigerator structure, maintaining manufacturing simplicity.
Solution Approach 2:
A cold air guiding device acts as an intermediary between the freezing compartment and the ice making compartment in the refrigerating compartment. This mediator transfers cold air from the freezing compartment to the ice making compartment, enabling ice production without requiring the ice maker to be physically located in the freezing compartment, thus avoiding complex structural changes.
3Ease of operation
If the ice making compartment is placed outside the freezing compartment, then accessibility improves, but refrigerator volume and manufacturing complexity increase
Solution Approach 1:
The ice making compartment is nested within the refrigerating compartment's vertical space, utilizing the area above the freezing compartment. This nested arrangement allows the ice making functionality to be incorporated without significantly increasing the overall refrigerator volume, as it uses otherwise underutilized space in the existing structure.

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 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.
