Refrigerator Foam Inserts for Uniform Cabinet Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Forming uniform insulating layers in cabinet structures, such as refrigerators, is challenging due to the difficulty in distributing insulating material around interior components, which can lead to defects like deformations in the cabinet shell.
Innovation Solution
The method involves using elongate supports made from expanded polystyrene foam or polyurethane insulating foam to space apart compartment liners within the cabinet shell, creating internal and external gaps that are filled with foam, ensuring uniform distribution and preventing foam shrinkage, while allowing for fluid communication between compartments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If insulating material is distributed about interior components within the cabinet structure, then insulating layers are formed, but uniformity of the insulating layers is difficult to achieve and deformations to the shell occur
Solution Approach 1:
Elongate supports are installed between compartment liners before the insulating foam is applied. These supports pre-establish the correct spacing and positioning, preventing the foam from causing deformations to the shell while ensuring uniform insulating layers are formed throughout the cabinet structure.
Solution Approach 2:
The elongate supports act as intermediary elements between the compartment liners and the insulating foam. They mediate the interaction by providing a rigid framework that maintains proper spacing during foam application, thereby achieving uniform insulating layers without shell deformations.
2Manufacturing precision
If compartment liners are spaced apart using traditional methods, then insulating layers can be formed, but uniform distribution of insulating material is difficult to achieve
Solution Approach 1:
The spacing function is segmented into multiple discrete elongate supports positioned at critical locations between compartment liners. This segmentation provides precise control over insulating material distribution without requiring a complex overall spacing mechanism, as each support independently maintains spacing in its local region.
Solution Approach 2:
The elongate supports are strategically positioned at specific locations where spacing is most critical for achieving uniform insulating layers. This local quality approach ensures uniform material distribution in key areas without adding complexity throughout the entire cabinet structure.

AI summary
A method of assembling a cabinet and an apparatus assembled according to the method are provided. The cabinet includes a shell with internal walls, a first compartment liner and a second compartment liner configured to be housed within the shell. The first compartment liner includes a first liner face and defines a first compartment. The second compartment liner includes a second liner face and defines a second compartment. The method includes the steps of positioning a pair of elongate supports between the first compartment liner and the second compartment liner such that the first liner face and the second liner face are adjacent one another and spaced apart.
