Refrigerator having a rotatable door for the ice making compartment forming the exterior appearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerators with ice-making compartments often suffer from reduced efficiency due to the ice-making compartment being integrated within the freezing or refrigerating compartments, leading to difficulties in temperature control and reduced ice-making efficiency, as well as inadequate insulation between compartments.
Innovation Solution
A refrigerator design featuring an independently insulated ice-making compartment with a dedicated ice-making unit directly cooled by a refrigerant pipe, separate from the freezing and refrigerating compartments, and a unique door mechanism for enhanced sealing and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the ice-making compartment is integrated within the freezing or refrigerating compartments, then the device complexity is reduced, but the temperature control precision and insulation performance deteriorate
Solution Approach 1:
The patent divides the refrigerator into separate functional compartments: a freezing compartment, a refrigerating compartment, and an independently positioned ice-making compartment. This segmentation allows each compartment to have dedicated insulation and temperature control systems, resolving the contradiction by maintaining structural simplicity while achieving precise temperature control through functional separation.
2Device complexity
If the ice-making compartment is integrated within the freezing or refrigerating compartments, then the device complexity is reduced, but the insulation performance deteriorates
Solution Approach 1:
The patent implements separate insulation systems for each compartment. The ice-making compartment has its own insulation layer independent of the freezing and refrigerating compartments, preventing thermal interference and improving overall insulation efficiency while maintaining a unified refrigerator structure.
3Productivity
If the ice-making compartment is independently provided with direct refrigerant cooling, then the ice-making efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent introduces a dedicated refrigerant pipe as an intermediary element that directly connects the refrigeration system to the ice-making compartment. This allows efficient heat transfer for rapid ice production while using a simple pipe extension rather than a complex independent refrigeration system, thus improving productivity without significantly increasing device complexity.

AI summary
A refrigerator includes a body, a refrigerating compartment provided inside the body, a freezing compartment positioned at a lower portion of the refrigerating compartment and provided inside the body, an ice-making compartment provided inside the body and provided with an insulated space that is separated from the refrigerating compartment and the freezing compartment, and an ice-making compartment door to insulate the ice-making compartment from an outside and rotatably installed at the body as to open/close the ice-making compartment. Cooling efficiency is improved by completely separating the ice-making compartment from the freezing compartment and the refrigerating compartment, and user convenience is improved by separately installing the ice-making compartment door.
