Oven Side Grid Stops for Controlled Rack Push-In and Pull-Out
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking oven designs lack a simple and low-complexity solution for preventing foodstuff supports from being pushed against the rear wall or pulled out unintentionally, which can cause damage and disrupt air circulation.
Innovation Solution
A foodstuff support system with lateral guiding devices formed as side grids, featuring upper and lower horizontal bars with rear and front embossings that act as push-in and pull-out stops, ensuring the support's symmetry and ease of assembly, allowing for double push-in and pull-out stops without complex mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stop elements are formed as broadening in the frame of the foodstuff support, then the pull-out-stop function is achieved, but the device complexity increases
Solution Approach 1:
The patent combines the push-in-stop and pull-out-stop functions into a single embossing element on the foodstuff support. The embossing interacts with both the rear embossing (for push-in-stop) and the front embossing (for pull-out-stop) of the guiding device, eliminating the need for separate stop elements and reducing structural complexity.
Solution Approach 2:
The embossing on the foodstuff support serves multiple functions: it acts as both a push-in-stop element and a pull-out-stop element by interacting with different embossings on the guiding device. This multi-functionality reduces the number of components needed while maintaining reliable stopping functions in both directions.
2Reliability
If a locking mechanism with multiple components is used, then the push-in-stop and pull-out-stop functions are achieved, but the ease of manufacture deteriorates
Solution Approach 1:
The patent merges multiple stop functions into a single embossing structure on the foodstuff support. This embossing works in conjunction with the embossings on the guiding device to provide both push-in-stop and pull-out-stop functions, significantly simplifying the manufacturing process compared to multi-component locking mechanisms.
Solution Approach 2:
The embossing structure is designed to automatically provide both push-in-stop and pull-out-stop functions through its geometric form and interaction with the guiding device embossings. The structure serves itself by using the same element for multiple stopping functions, eliminating the need for separate components and complex assembly procedures.
3Ease of operation
If the foodstuff support can be pushed against the rear wall, then the ease of operation is improved, but the object-affected harmful factors increase
Solution Approach 1:
The patent implements a push-in-stop function that prevents the foodstuff support from being pushed against the rear wall before damage can occur. The rear embossing on the guiding device interacts with the embossing on the foodstuff support to create a stopping force that counteracts the pushing force, protecting the rear wall from damage while allowing normal sliding operation.
4Ease of operation
If the foodstuff support lacks a pull-out-stop, then the ease of operation is improved, but the reliability deteriorates
Solution Approach 1:
The patent implements a pull-out-stop function that prevents unintentional pulling out of the foodstuff support before it can cause problems. The front embossing on the guiding device interacts with the embossing on the foodstuff support to create a stopping force that counteracts unintended pull-out forces, while allowing intentional removal when needed.

AI summary
The present invention relates to a cooking oven with at least one slidable foodstuff support (10) and at least one pair of lateral guiding devices (32, 34) for said foodstuff support (10). The foodstuff support (10) includes at least one support embossing (22) formed in a lateral border (20) of said foodstuff support (10). The guiding devices (32, 34) of one pair are arranged at two opposite side walls of an oven cavity. At least one guiding device (32, 34) includes a rear embossing (26) interacting with the support embossing (22), so that the support embossing (22) and the rear embossing (26) form a push-in-stop for the foodstuff support (10) . The at least one guiding device (32, 34) includes a front embossing (28) interacting with the support embossing (22), so that the support embossing (22) and the front embossing (28) form a pull-out-stop for the foodstuff support (10). The rear embossing (26) and the front embossing (28) extend into directions opposite to the direction of the support embossing (22). Further, the present invention relates to a corresponding foodstuff support (10) for the cooking oven. Additionally, the present invention relates to a side grid (30) for a side wall in an oven cavity of the cooking oven.
