Modular Refrigerator Gasket Assembly with Detachable Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerator gasket assemblies are labor-intensive to assemble, require replacement of the entire gasket when only a portion is worn, and are bulky for shipping due to manufacturing before shipping.
Innovation Solution
A modular gasket assembly with detachable sections connected using a two-piece or three-piece coupler, allowing for selective disconnection and replacement of individual sections, reducing assembly time and enabling more efficient shipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire gasket is manufactured as a single unit before shipping, then the gasket maintains structural integrity and sealing performance, but the shipping volume and cost increase due to the need to ship the complete assembly even when only a portion is worn
Solution Approach 1:
The gasket is divided into multiple separate sections (top, bottom, left side, right side) that can be manufactured independently and shipped separately. Each section contains its own coupling mechanisms (male/female connectors) to assemble into a complete rectangular gasket at the installation location, reducing shipping volume while maintaining the ability to form a complete sealing structure when needed.
2Reliability
If the entire gasket is manufactured and shipped as a complete unit, then the gasket provides complete sealing coverage, but assembly time and labor intensity increase due to the complexity of joining multiple sections
Solution Approach 1:
The gasket is segmented into four independent sections that can be manufactured separately and assembled at the installation site using simple coupling mechanisms. This segmentation reduces assembly complexity and time while still providing complete sealing coverage when all sections are properly connected.
Solution Approach 2:
Coupling mechanisms (male and female connectors) serve as intermediaries between the separate gasket sections, enabling quick and simple assembly without requiring complex joining processes. These connectors facilitate easy connection and disconnection of sections during installation or replacement.
3Reliability
If the entire gasket is replaced when only a portion is worn, then the complete gasket ensures continuous sealing performance, but material waste and cost increase due to replacing functional sections
Solution Approach 1:
The gasket is divided into replaceable sections that can be independently removed and replaced. When one section becomes worn or damaged, only that specific section needs to be replaced rather than the entire gasket, reducing material waste while maintaining sealing performance through the remaining functional sections during the replacement process.
Solution Approach 2:
The gasket system transitions from a static, monolithic structure to a dynamic, modular system where sections can be independently replaced. This dynamic approach allows the gasket to adapt to wear patterns by replacing only the necessary sections, extending the overall service life of the gasket assembly.
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
Facilitates easier assembly, allows for section-by-section replacement, and reduces shipping volume by enabling disconnection of worn sections, thereby improving efficiency and reducing waste.
Implementation Method 1
The bellows portion 514 is flexible and defines a bellows cavity 516
Implementation Method 2
The cabinet engaging portion 512 has a cavity 518 for holding a strip of magnetic material 520, which when the door is closed will be attracted to magnetic material in the face portion of the cabinet to maintain the refrigerator door in a closed position
Implementation Method 3
The ends of the gasket sections are then spliced together by heat welding the sections to one another to form the final gasket

AI summary
A refrigerator gasket assembly has a first gasket section, a second gasket section and a coupler connecting the first gasket section and the second gasket section. The coupler is configured to permit the selective connection and disconnection of the first gasket section from the second gasket section. In some variations, the coupler is a two piece coupler and in other variations the coupler is a three piece coupler.
