Household cooling appliance containing a specifically configured plate-like separation unit in a receiving space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household cooling appliances with plate-like separation units lack a modular and easily installable solution for integrating light modules, which complicates the mounting process and requires additional fastening elements that may be thermally disadvantageous.
Innovation Solution
A household cooling appliance featuring a plate-like separation unit with a module carrier that accommodates a light module, utilizing a snap-fit connection for easy installation and removal, and an adhesive bond for attaching the module carrier to the base plate, eliminating the need for additional fastening elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the light module is directly fastened to the glass base plate using adhesive bond or additional fastening elements, then the mounting is stable, but the installation complexity increases and thermal disadvantages occur
Solution Approach 1:
The patent introduces a module carrier as an intermediary component between the light module and the glass base plate. The module carrier receives the light module in a receptacle and provides a mounting interface, eliminating the need for direct fastening of the light module to the glass plate. This intermediary structure simplifies installation by providing a standardized mounting interface while maintaining secure attachment through the carrier's design features such as retaining walls and engagement structures.
2Reliability
If additional fastening elements like screws are used to attach the light module to the base plate, then the mounting is stable, but the installation process becomes more complex and time-consuming
Solution Approach 1:
The patent segments the mounting system into distinct functional components: the module carrier with its receptacle structure and the light module with integrated mounting features. The carrier includes retaining walls and engagement structures that work with corresponding features on the light module to provide stable mounting without requiring separate fastening elements. This segmentation allows for tool-free installation while maintaining secure attachment.
3Reliability
If adhesive bond is used directly on the glass base plate, then the mounting is stable, but thermal management is compromised
Solution Approach 1:
The module carrier serves as a thermal intermediary, positioning the light module at a distance from the glass base plate. This spacing allows for thermal management by preventing direct heat transfer to the glass surface, which could cause thermal stress or condensation. The carrier structure provides a thermal buffer while maintaining mechanical stability through its engagement features.

AI summary
A household cooling appliance contains a housing and a first receiving space for food configured in the housing. A plate-like separation unit, which is releasably arranged in the first receiving space, is arranged for separation of the volume of the first receiving space. The separation unit contains a base plate, wherein on the bottom side of the base plate a module carrier is arranged for receiving a function module of the separation unit, which is a light module. The light module is releasably arranged to be sunk in a receptacle of the module carrier at least in part and is held therein by a fixing connection.
