Profiled arrangement, particularly for a refrigerator and/or freezer device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing profiled arrangements for refrigerators and freezers are prone to contamination in the expansion folds of bellows seals, making them difficult to clean, and their visual appearance is not aesthetically pleasing when the gap between the door and cabinet body is closed.
Innovation Solution
A profiled arrangement with a profiled element that has a free end disposed on the sealing arrangement and connected to the base via a movement arrangement, which relocates the necessary movement to a non-visible region, allowing for a visually appealing and easy-to-clean design that maintains tolerance compensation and sealing functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bellows constructions are used to compensate tolerances and provide sealing, then the sealing functionality and tolerance compensation are improved, but the visual appearance deteriorates and cleaning becomes difficult due to visible expansion folds prone to contamination
Solution Approach 1:
The invention extracts the bellows construction from the visible region and relocates it to a non-visible region. The profiled element is designed with a first region in the visible area that has a first design (aesthetically pleasing, easy to clean), and a second region in the non-visible area that contains the bellows construction for tolerance compensation. This separation allows the sealing functionality to be maintained while eliminating the visual and cleaning drawbacks of visible expansion folds.
Solution Approach 2:
The invention transitions from a single-region design to a multi-region design along the longitudinal axis. The profiled element is divided into a first region (visible) and a second region (non-visible), allowing different functional and aesthetic requirements to be satisfied in different spatial dimensions. The bellows construction is placed in the second region, enabling tolerance compensation without affecting the visual appearance of the first region.
2Manufacturing precision
If bellows constructions with expansion folds are used, then tolerance compensation is improved, but ease of cleaning deteriorates due to contamination-prone folds
Solution Approach 1:
The bellows construction is extracted from the visible, easily accessible region and placed in the non-visible region. This allows the profiled element to have a smooth, continuous surface in the visible area that is easy to clean, while the tolerance compensation function is maintained in the non-visible area where cleaning is less critical.
Solution Approach 2:
The profiled element is segmented into multiple regions with different functions: a first region in the visible area with a smooth surface for easy cleaning, and a second region in the non-visible area containing the bellows construction for tolerance compensation. This segmentation allows each region to be optimized for its specific purpose.
3Ease of operation
If a simple linear profiled element is used, then ease of cleaning and visual appearance are improved, but adaptability to various gap dimensions deteriorates
Solution Approach 1:
The profiled element incorporates a dynamic bellows construction in its non-visible region, which can expand and contract to accommodate variations in gap dimensions. This dynamic region provides adaptability to different installation conditions while the visible region maintains a simple, clean design that is easy to maintain.
Solution Approach 2:
The profiled element is divided into a first region with a simple, smooth design for easy cleaning and visual appeal, and a second region with a bellows construction that provides adaptability to various gap dimensions. This segmentation allows the element to simultaneously achieve ease of cleaning and adaptability.
