Household refrigerator with specific cover system in a receiving space for food
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Household refrigerators with additional panels behind the inner container's back wall face limitations in air circulation, leading to inefficient cooling and potential moisture accumulation, which can result in ice formation and increased assembly complexity.
Innovation Solution
A modular cover system where a separate covering plate is positioned in front of the inner container's wall, with a non-overlapping design allowing for easier access and individual adjustment of cover parts, incorporating a spacer web for gap management and integration of additional functional units like air channels and dispensing systems, reducing assembly effort and enhancing cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large covering plate extending over the entire height of the back wall is used, then the functional units are covered and protected, but the assembly effort increases and individuality is reduced
Solution Approach 1:
The covering plate is divided into multiple separate cover parts that can be individually assembled and disassembled. Each cover part covers a specific functional unit or region, allowing for selective assembly based on the specific requirements of the refrigerator model, thereby reducing overall assembly complexity while maintaining adequate coverage and protection.
2Reliability
If a large covering plate extending over the entire height of the back wall is used, then the functional units are covered and protected, but individuality and adaptability are reduced
Solution Approach 1:
The covering plate is divided into multiple separate cover parts that can be individually assembled and disassembled. Each cover part covers a specific functional unit or region, allowing for selective assembly based on the specific requirements of the refrigerator model, thereby reducing overall assembly complexity while maintaining adequate coverage and protection.
3Reliability
If the covering plate overlaps the functional unit, then complete coverage is achieved, but access to individual local sections becomes difficult
Solution Approach 1:
The covering plate is divided into multiple separate cover parts that can be individually assembled and disassembled. Each cover part covers a specific functional unit or region, allowing for selective assembly based on the specific requirements of the refrigerator model, thereby reducing overall assembly complexity while maintaining adequate coverage and protection.
4Adaptability or versatility
If additional panels are added behind the inner container wall, then functional units can be arranged, but air circulation is limited
Solution Approach 1:
The patent positions the functional units in the depth direction of the refrigerator, behind the covering plate but in front of the back wall, creating a layered spatial arrangement. This dimensional organization allows air to circulate freely in the receiving space without being blocked by panels, while still providing adequate space for functional units to be installed in the depth dimension.

AI summary
A household refrigerator has a receiving space for food which is delimited by walls of an inner container. A covering plate that is separate from the inner container is arranged in the receiving space in front of a wall of the inner container. A functional unit of the household refrigerator is arranged in the receiving space in front of the wall and in one spatial direction of the household refrigerator the covering plate ends next to the functional unit. The functional unit is covered, at least in certain sections, by a cover that is separate from the covering plate.
