Solution Overview
Problem
Household refrigeration appliances require specific adaptations for different equipment classes, leading to increased complexity and cost due to the need for unique openings, grooves, and tools, limiting the interchangeability of refrigerated goods trays and shelves across classes.
Innovation Solution
A household refrigeration appliance design featuring insert parts with latching elements that can be locked into place, allowing the same refrigerated goods container to accommodate either insert parts or telescopic rails, enabling the same container to be used in both lower and higher equipment classes without significant modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If specific openings or grooves are provided for different equipment classes, then the refrigerated goods container can be adapted to specific equipment classes, but the variety of parts and manufacturing complexity increases
Solution Approach 1:
The patent implements a universal mounting system where a single type of opening and backing part design serves multiple equipment classes. The insert part with latching element can be used in both lower equipment classes (with insert parts) and higher equipment classes (with telescopic rails), eliminating the need for different opening and groove designs for different equipment classes.
Solution Approach 2:
The mounting system is segmented into modular components: the opening in the refrigerated goods container, the backing part attached to the container, and the insert part with latching element. This segmentation allows the same basic structure to be configured for different equipment classes without requiring different opening or groove designs.
2Adaptability or versatility
If different openings and grooves are designed for different equipment classes, then specific equipment class requirements are met, but manufacturing tools and production steps must be increased
Solution Approach 1:
The patent establishes a universal opening design that can accommodate both insert parts for lower equipment classes and telescopic rails for higher equipment classes. The same opening geometry, backing part attachment method, and latching mechanism are used across all equipment classes, eliminating the need for different manufacturing tools for different opening types.
3Reliability
If refrigerated goods trays are adapted to specific equipment classes, then they can be properly mounted, but interchangeability between equipment classes is limited
Solution Approach 1:
The mounting system is designed to be dynamically adaptable rather than statically fixed to one equipment class. The insert part with latching element provides a standardized interface that maintains reliable mounting for refrigerated goods trays across different equipment classes, allowing the same tray to be interchangeably mounted on both insert parts and telescopic rails.

AI summary
The present invention relates to a household refrigerating appliance (100) comprising a refrigerated goods container (106) with an inside which delimits a receiving space (112) for food, and two insert parts (200a, 200b), the insert parts (200a, 200b) being attached to side walls (107 , 108) are attached to the inside of the refrigerated goods container (106) and each insert part (200a, 200b) has a latching element (232) which extends through an opening (120) in the refrigerated goods container (106) and has a latching receptacle (124) of a backing part ( 122) is locked. Furthermore, the present invention relates to a refrigerated goods tray (300) for a household refrigeration appliance (100) comprising a bottom surface (302) and two side surfaces (304, 306), each side surface (304, 306) having a receiving area (312) for alternatively receiving a refrigerated goods container side wall (108) attached guide rib (202) or a telescopic rail attached to a refrigerated goods container side wall (108), the receiving area (312) is limited by a shell guide surface (310, 310E) in the direction of the bottom surface (302), a pull-out limitation (314). of the side surface (304, 306), and a portion of the receiving area (TA1) is arranged between the tray guide surface (310, 310E) and the extension limit (314).
