Refrigerator Accommodation Container for Cool Air Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerators lose cool air when the door is opened, affecting the temperature stability of sensitive foods like kimchi, vegetables, and fish, and existing cool air covers are not suitable for large refrigerators or allow full opening for single container access.
Innovation Solution
The design includes an accommodation container with a box shape and adjustable walls to minimize cool air release, featuring a handle and protrusions for easy access and placement, allowing the cool air to circulate around the food storage container without releasing it to the front, and the accommodation container is formed using transparent or semi-transparent materials for visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a cool air cover is installed at the front surface of the storage compartment to prevent cool air release, then cool air loss is reduced, but the device complexity increases and it is not suitable for large-size refrigerators with pair of doors
Solution Approach 1:
The invention divides the storage compartment into multiple partitions, with each partition having its own door and cool air retention structure. This segmentation allows individual access to specific partitions without opening the entire storage compartment door, reducing cool air loss while maintaining a simple overall structure without requiring a complex full-coverage cool air cover.
2Ease of operation
If the entire cover is opened to access a single food storage container, then accessibility is improved, but cool air loss increases
Solution Approach 1:
Each partition is equipped with its own door that can be opened independently. When a user needs to access a specific food storage container, only the door of that particular partition needs to be opened, not the entire storage compartment. This segmented access design maintains ease of operation for individual containers while minimizing cool air loss by keeping other partitions sealed.
3Ease of manufacture
If the front side wall has the same height as other walls, then manufacturing is simplified, but cool air cannot be prevented from escaping to the front side
Solution Approach 1:
The front side wall is designed with a different height than the rear side wall, left side wall, and right side wall. The front side wall extends higher to align with the front surface of the storage compartment, creating an asymmetric structure that effectively blocks cool air from escaping to the front when the door is open. This asymmetric design prioritizes cool air retention over manufacturing simplicity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution prevents cool air loss when the door is open, enhances accessibility to food storage containers, and maintains temperature stability by allowing cool air to circulate around the food storage container, improving the preservation of sensitive foods.
Implementation Method 1
The front side wall has a height corresponding to a height of the food storage container to prevent the cool air around the food storage container from being released to a front side of the refrigerator
Implementation Method 2
The rear side wall, the left side wall, and the right side wall have heights lower than the height of the front side wall to allow the cool air to flow around the food storage container

AI summary
A refrigerator capable of preventing a cool air from being released when a door is open by having an accommodation container, including a bottom wall, a front side wall, a rear side wall, and lateral side walls to form an accommodation space, stored in a storage compartment together with a food storage container while accommodating the food storage container, the lateral side walls being spaced from the food storage container to form a space that allows a cool air to remain around the food storage container, the front side wall having a height corresponding to a height of the food storage container to prevent the cool air around the food storage container from being released, and the rear side wall and the lateral side walls having heights lower than the height of the front side wall to allow the cool air to flow around the food storage container.
