Refrigerator door with a replaceable door panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and inconvenience of replacing refrigerator door bodies to meet changing aesthetic demands, as well as the instability and complexity of existing assembly methods, are not adequately addressed by current technologies.
Innovation Solution
A refrigerator door design featuring a detachable decorative panel that uses a rotary latch and limiting members for snap-fitting connections, allowing quick assembly and detachment without screws, and limiting panel displacement through snap-fitting structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the whole door body of the refrigerator is replaced to achieve changes in appearance, then the aesthetic demands are satisfied, but the cost is high and the use of the refrigerator is affected
Solution Approach 1:
The door assembly is divided into two independent parts: a door body and a decorative door panel. The decorative panel can be detached and replaced independently from the door body, allowing users to change appearance without replacing the entire door assembly. This segmentation enables cost-effective aesthetic updates while maintaining the functional integrity of the refrigerator door.
2Ease of operation
If simple snap-fitting structures are used for assembly, then the detachment is simpler and more convenient, but the stability of assembly may be compromised
Solution Approach 1:
The rotary latch mechanism provides a dynamic locking system that transitions between locked and unlocked states. When rotated to the locked position, the latch engages with the lock post to secure the panel firmly. When rotated to the unlocked position, the engagement is released for easy detachment. This dynamic mechanism provides both strong holding force during use and simple release when needed.
Solution Approach 2:
Multiple limiting functions are merged into a single integrated latch structure. The rotary latch simultaneously performs: (1) limiting displacement in the up-down direction through engagement with the lock post, and (2) limiting displacement in the front-rear direction through cooperation with the limiting member. This merging of multiple constraints into one mechanism simplifies the assembly while ensuring comprehensive stability.

AI summary
The present invention provides a refrigerator door with a replaceable door panel, comprising: a door body and a decorative door panel detachably connected to the door body; a rotary latch and a limiting member are disposed on the door body; a rear side of the decorative door panel facing towards the door body comprises a second limiting member and a lock post; wherein when the decorative door panel is assembled on a front side of the door body, the rotary latch and the lock post snap-fit each other to limit a displacement of the decorative door panel in an up-down direction; the first limiting member cooperates with the second limiting member to limit a displacement of the decorative door panel in a front-rear direction.
