Refrigerator Door Panel Trim Assembly for Easy Design Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigerators face challenges in easily changing door designs and preventing the edge of a door panel from separating from the door body during assembly or disassembly.
Innovation Solution
The design incorporates a door system with a rotatable door body, a panel body, and trim components that include grooves, protrusions, and cut-out portions for secure coupling and easy detachment, along with a buffer member to absorb impacts and prevent edge separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the door panel is fixed to the door body using traditional fastening methods, then the attachment is secure, but the design cannot be easily changed and the panel edge may separate during assembly or disassembly
Solution Approach 1:
The door assembly is divided into separate components: door body, panel body, and trim. The trim acts as a detachable connector that segments the attachment system, allowing the panel to be easily separated from the door body while maintaining secure attachment when connected. This segmentation enables design changes by allowing different panel or trim configurations.
Solution Approach 2:
The trim is positioned to extend from the panel body and nest within or alongside the door body structure. The first trim protrusion fits into the first trim groove, creating a nested connection that secures the panel to the door body while allowing for easy detachment and reconfiguration.
2Reliability
If the trim is rigidly fixed to prevent separation, then the attachment stability is improved, but the ease of assembly and disassembly is reduced
Solution Approach 1:
The trim connection system transitions from a static rigid fixation to a dynamic detachable connection. The trim can be easily inserted and removed from the grooves, allowing the system to adapt between secured (attached) and flexible (detached) states. This dynamic capability enables both stable attachment and easy reconfiguration.
Solution Approach 2:
The trim acts as an intermediary component between the panel body and door body. It provides the connection function while allowing for easy insertion and removal. The intermediary trim with its protrusions and grooves mediates the attachment process, making assembly and disassembly simple operations while maintaining reliable connection when attached.
3Reliability
If multiple fixing members are used to secure the trim, then the attachment stability is improved, but the device complexity and assembly time increase
Solution Approach 1:
The complex multi-point fastening system is extracted and replaced with a simplified groove-protrusion interface. Instead of multiple separate fixing members, the connection function is integrated into the trim structure itself through the groove-protrusion geometry, reducing component count and assembly complexity while maintaining attachment stability.
Solution Approach 2:
The functions of multiple fixing members are merged into the integrated groove-protrusion connection system. The first trim protrusion fitting into the first trim groove combines alignment, connection, and securing functions into a single integrated mechanism, reducing device complexity while maintaining reliable attachment.

AI summary
A refrigerator including a main body forming a storage compartment, and a door configured to open and close the storage compartment. The door includes a door body rotatably coupled to the main body and including an insulator therein, a panel body positioned in a front of the door body, a first trim disposed at a first edge of the panel body and configured to be coupled to the door body while being rotated with respect to the door body, and a second trim disposed at a second edge opposite to the first edge of the panel body and configured to be coupled to the door body when the first trim is coupled to the door body.
