Refrigerator Inner Door Control Unit to Minimize Cool Air Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerators often lose cool air when accessing the control unit or door guards, and the placement of control units within the storage compartments can lead to inefficiencies in temperature and humidity control, as well as aesthetic and operational issues.
Innovation Solution
A refrigerator design featuring a control unit mounted on the inner door, accessible via an auxiliary outer door, which allows for independent operation of the inner and outer doors to minimize cool air loss and enhance food storage options, with the control unit including a display and operational components and a housing that includes a transparent member for visibility and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the control unit is installed inside the storage compartment, then it can control the internal environment, but it causes inefficiency in temperature and humidity control and aesthetic issues
Solution Approach 1:
The door assembly is segmented into an inner door and an outer door that can operate independently. The control unit is mounted on the inner door, allowing it to be accessed through the auxiliary opening in the outer door without opening the main storage compartment door. This segmentation resolves the contradiction by separating the control function from the storage space while maintaining aesthetic appearance.
2Ease of operation
If the main door is opened to access the control unit or door guards, then the control unit can be operated, but cool air is lost
Solution Approach 1:
An auxiliary door with an auxiliary opening serves as an intermediary element between the user and the control unit. This intermediary allows access to the control unit and door guards through a smaller opening rather than the full main door, minimizing the volume of cool air that escapes during operation.
3Adaptability or versatility
If an auxiliary door is added to access door guards, then food storage options increase and cool air is preserved, but device complexity increases
Solution Approach 1:
The auxiliary door serves multiple functions: it provides access to door guards for food storage, allows operation of the control unit, and preserves cool air by minimizing opening size. This multi-functionality resolves the contradiction by making a single structural element serve several purposes rather than adding separate components for each function.

AI summary
A refrigerator may include a storage compartment, an inner door which comprises an opening having a size corresponding to a size of the storage compartment, a plurality of door guards, and an outer door which open and close the storage compartment, wherein the inner door comprises a control unit may control an internal environment of the storage compartment.
