Refrigerator Door Aluminum Profile for Stable Cover Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerator door upper compartments with plastic coverings experience mechanical instability, leading to bending and displacement due to inadequate support from plastic claws, resulting in a less robust and aesthetically unappealing design.
Innovation Solution
The use of an aluminum profile with lateral coverings and an additional guiding means embedded with a panel fixing element, which includes an ornamental spacing element for easier mounting and enhanced visual appeal, replacing plastic coverings with a more robust material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If plastic coverings are used on the refrigerator door, then the door can be manufactured with lighter materials and easier assembly, but the coverings experience bending and displacement due to inadequate mechanical support
Solution Approach 1:
The patent combines plastic coverings with aluminum profile elements to create a composite structure. The aluminum profile provides rigid mechanical support while the plastic covering maintains aesthetic appearance and ease of assembly. This composite approach allows the lightweight plastic material to be used without suffering from its inherent mechanical weaknesses.
Solution Approach 2:
The aluminum profile acts as an intermediary element between the door frame and the plastic covering. It provides the necessary mechanical support and structural stability, mediating between the rigid door frame and the flexible plastic covering to prevent bending and displacement while maintaining ease of assembly.
2Ease of operation
If plastic claws are used to attach coverings to the door frame, then the assembly process is simplified, but the mechanical connection is inadequate and can break or demount with small force
Solution Approach 1:
The patent replaces pure plastic attachment mechanisms with a composite system combining aluminum profile elements and plastic coverings. The aluminum profile provides strong mechanical attachment points while maintaining the simplicity of plastic assembly methods, thereby increasing connection strength without sacrificing ease of mounting.
Solution Approach 2:
The attachment system is segmented into distinct functional elements: the aluminum profile provides structural support and attachment points, while the plastic covering provides aesthetic finish and simple assembly characteristics. This segmentation allows each material to perform its optimal function.
3Reliability
If a more robust material like aluminum is used for the door covering, then bending and displacement are eliminated, but the visual appeal and aesthetic quality may be reduced compared to plastic coverings
Solution Approach 1:
The patent uses composite materials where the aluminum profile provides the structural framework and mechanical stability, while the plastic covering maintains the aesthetic appearance. This allows the door to achieve both robustness and visual appeal through the synergistic combination of materials.
Solution Approach 2:
The patent applies different material qualities to different parts of the door structure. The aluminum profile is used in areas requiring mechanical strength and stability, while plastic coverings are used in areas where aesthetic appearance is prioritized. This local differentiation of material properties optimizes both reliability and visual appeal.

AI summary
A refrigerator having a deep freeze compartment door with an aluminum profile having lateral coverings at both sides and an additional guiding means mounted on a panel fixing element. The panel fixing element is embedded with the outer part of the door such that an ornamental spacing element is fixed to the guiding element and to the lateral coverings such that an easier on site mounting is obtained and a more appealing visual effect is achieved.
