Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerator door panel mounting systems face challenges with productivity and accuracy due to exposed brackets, complex installation processes, and increased manufacturing costs, particularly when dealing with heavy panels and complex geometries.
Innovation Solution
A refrigerator door design featuring a panel assembly with a first and second cap decor, an insulator, and brackets that allow for easy mounting and detachment, utilizing a system of cap decors, brackets, and an insulator to maintain a firm and aesthetically pleasing mounting of panels without exposing brackets externally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple brackets are mounted on the outside to mount the panel, then the panel can be securely fixed, but productivity deteriorates and accurate mounting position cannot be maintained
Solution Approach 1:
The door body is segmented into multiple regions with recessed grooves positioned at specific locations. These grooves divide the mounting function into discrete locations, allowing the panel to be securely fixed at multiple points without requiring multiple external brackets. The segmentation of the door body structure enables efficient panel mounting while maintaining productivity.
Solution Approach 2:
The mounting structure is nested within the door body itself through recessed grooves that are formed as integral parts of the door. Instead of adding external mounting elements, the mounting features are nested within the existing door structure, eliminating the need for separate external brackets and improving both productivity and mounting accuracy.
2Ease of manufacture
If brackets for coupling are exposed to both sides of the door, then the panel can be mounted, but the outer appearance deteriorates
Solution Approach 1:
The mounting function is extracted from external brackets and integrated into the door body structure itself. The recessed grooves are formed directly in the door body, eliminating the need for separate external brackets. This extraction of the mounting function into the door structure maintains manufacturing ease while improving outer appearance by removing exposed coupling elements.
Solution Approach 2:
The mounting structure is merged with the door body by forming recessed grooves as an integral part of the door structure. Instead of combining separate door and bracket components, the mounting features are merged into the door itself, creating a unified structure that maintains ease of manufacture while eliminating exposed brackets for better appearance.
3Reliability
If multiple installation portions are disposed on the rear surface of the glass panel, then the panel can be mounted, but workability and productivity deteriorate due to coupling difficulty
Solution Approach 1:
Instead of providing multiple protruding installation portions on the panel that need to be coupled to the door, the structure is inverted: recessed grooves are formed in the door body and the panel is inserted into these grooves. This inversion simplifies the mounting operation by eliminating the need to align and couple multiple protruding elements, thereby improving workability while maintaining mounting security.
4Force
If large groove and installation portion or many grooves and installation portions are required for supporting heavy panel, then the panel can be supported, but the door volume increases and manufacturing cost increases
Solution Approach 1:
Instead of providing large or numerous grooves throughout the door structure, recessed grooves are strategically positioned at specific locations where they can most effectively support the panel. The grooves are designed with optimal local geometry to provide maximum support capability with minimal volume consumption, thereby supporting heavy panels without increasing door volume or manufacturing cost.

AI summary
A refrigerator includes a cabinet and a door. The door includes a door liner, a front plate, a first cap decor coupled to the door liner and the front plate, a second cap decor coupled to the door liner and the front plate at a position facing the first cap decor, an insulator filled into a space defined by coupling of the door liner, the front plate, and the cap decors, and a panel assembly disposed detachably in front of the front plate. The panel assembly includes a panel defining an outer appearance of a front surface of the door, a first bracket protruding from a rear surface of the panel and inserted into the first cap decor, and a second bracket provided on the rear surface of the panel and supported by the second cap decor.
