Door for a household refrigeration device with identical mounting device in lateral ducts of opposite lateral sides, and household refrigeration device and method for producing a door
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current household refrigeration appliance doors lack variability and require a wide range of different components, limiting the use of identical components across device variants, which increases assembly effort and component storage needs.
Innovation Solution
The door design features laterally open channel troughs on both vertical longitudinal sides with interchangeable mounting areas for bearing parts and functional components, such as electronic display units, allowing for flexible assembly without modification, enabling the same components to be used for both left and right hinged configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different components are used for left and right hinged configurations, then the door can be adapted to different household refrigeration appliance variants, but the number of identical components that can be used is limited and assembly effort increases
Solution Approach 1:
The mounting area is designed with a universal structure that can accommodate both bearing parts for door hinges and functional parts for electronic display units. The recess and mounting means are configured to accept different component types without requiring conversion, allowing the same mounting area to serve multiple functions across different door configurations.
Solution Approach 2:
The mounting area is divided into a recess portion and a mounting means portion, allowing separate bearing parts and functional parts to be independently assembled. This segmentation enables flexible combination of different components while using the same base mounting structure, reducing the need for multiple specialized mounting areas.
2Adaptability or versatility
If multiple different components are required for various door configurations, then device variants can be created, but assembly effort and component storage needs increase
Solution Approach 1:
The mounting area serves as a universal interface for both bearing parts and functional parts. The same recess and mounting means structure is used regardless of whether a bearing part or functional part is installed, eliminating the need for separate mounting areas for different component types and significantly reducing assembly effort.
Solution Approach 2:
The mounting area is pre-configured with the recess and mounting means during door manufacturing, allowing bearing parts and functional parts to be directly assembled without requiring any conversion or modification of the mounting area. This preliminary preparation eliminates time-consuming assembly steps.
