Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household refrigeration appliances face challenges in improving the positioning of trays during movement and ensuring the extended position is easily adjustable while effectively managing leverage and torsional forces, especially with large and heavily loaded trays.
Innovation Solution
A household refrigeration appliance with a guide system and a tilt protection and/or extension stop device that includes a stop element and a stabilizing element, where the stop element is mechanically stabilized by a stabilizing element connected to the tray and the appliance's shell, absorbing and dissipating forces to prevent bending or breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a stop element is designed to abut with a counter-stop element to limit tray extension, then the tray positioning is improved, but the stop element is subjected to high leverage and torsional forces that may cause bending or breakage
Solution Approach 1:
The stop device is segmented into a stop element and a separate stabilizing element. The stabilizing element is connected to both the stop element and the tray, creating a triangular support structure that distributes the leverage and torsional forces away from the stop element, preventing bending or breakage while maintaining precise tray positioning.
2Reliability
If the stabilizing element is added to connect the stop element to the tray, then the stop element is stabilized and force absorption is improved, but the device complexity increases
Solution Approach 1:
The stabilizing element is integrated into the existing tray structure, merging the stabilization function with the tray itself. This approach adds minimal complexity to the guide system while providing reliable force distribution, as the stabilizing element utilizes the tray's existing structural integrity.

AI summary
One aspect of the invention relates to a household refrigeration appliance (1) with a receiving compartment (3, 5) for foodstuffs, which is bounded by walls (17, 43), with a tray (7, 8, 9, 10, 11) for receiving stored goods, which is slidably arranged in the receiving compartment (3, 5) by means of a guide system (12) of the household appliance (1), wherein the guide system (12) has a guide unit (13, 14, 15) which is arranged on at least one of the walls (17, 43), and with a tilt protection and/or extension stop device (27, 28) which limits the extension and/or tilting of the tray (7, 8, 9, 10, 11) in the extended state, wherein the tilt protection and/or extension stop device (27, 28) has a tray-side stop element (29) which projects laterally from the tray (7, 8, 9, 10, 11). 8, 9, 10, 11) is arranged and is in an extended position of the shell (7, 8, 9, 10, 11) for abutting against a counter-stop element (36) external to the shell,so that the tilt protection and/or the extension stop is formed, wherein the shell (7, 8, 9, 10, 11) has a stabilizing element (33) which is connected to the shell-side stop element (29) and ends at a shell part (34) of the shell (7, 8, 9, 10, 11), so that the shell-side stop element (29) is stabilized.
