Multimount Oven Rack for Bottom or Sidewall Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oven racks lack flexibility and maximize usable space, as they cannot be easily installed on both sidewall shelf portions and the bottom surface of the oven chamber without interfering with the door or other components, limiting the options for users.
Innovation Solution
A multimount oven rack with a planar top and lower surface, supported by wire rods and crossbars, allowing it to be placed on sidewall shelf portions or the bottom surface, featuring stop and anti-tilt members to prevent movement and tilting, ensuring compatibility with both hidden and non-hidden bake elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the oven rack is mounted on sidewall shelf portions at standard heights, then the rack is supported at multiple heights for flexibility, but the usable space is reduced due to interference with the door and other components
Solution Approach 1:
The oven rack is designed with a universal support structure that can function in multiple mounting configurations - either on the sidewall shelf portions at standard heights or directly on the bottom surface of the oven chamber. This multi-functionality allows the same rack to adapt to different space requirements without needing separate racks for different positions.
Solution Approach 2:
The rack design adds a new dimensional option for mounting by enabling placement on the bottom surface of the oven chamber in addition to the traditional sidewall shelf portions. This dimensional change (from vertical sidewall mounting to horizontal bottom surface mounting) creates additional usable space above the bake element while maintaining rack support functionality.
2Volume of moving object
If the rack is placed on the bottom surface to maximize space, then usable space increases, but the rack may move or tilt without proper constraints
Solution Approach 1:
The rack incorporates stop members and anti-tilt members as preliminary constraint features that are built into the rack structure itself. These features proactively prevent movement and tilting before they can occur, ensuring the rack remains stable when placed on the bottom surface without requiring additional external constraints.
Solution Approach 2:
The stop members and anti-tilt members act as intermediary elements between the rack and the bottom surface of the oven chamber. These intermediaries provide the necessary mechanical constraints (stopping forward movement and preventing tilting) while allowing the rack to maintain its functional position for cooking.
3Volume of moving object
If the rack height is reduced to accommodate taller cooking ware, then space utilization improves, but the rack may interfere with the bake element when mounted on sidewalls
Solution Approach 1:
The rack system provides dynamic positioning options where the effective rack height can be adjusted by choosing different mounting locations. When taller cooking ware is needed, the rack can be mounted on the bottom surface, effectively reducing the distance from the bottom to the rack top. When mounted on sidewalls, the rack maintains standard height clearance from the bake element. This dynamic adaptability resolves the conflict between accommodating tall items and avoiding interference.

AI summary
An oven rack is received in an oven above a lower surface of the chamber and having a bake element mounted in the chamber either above or below the lower surface. The oven rack is configured to support cooking ware on one of the lower surface of the oven chamber or on rack shelf portions provided in sidewalls of the chamber. The rack includes a first portion having a substantially planar top surface, a second portion having a substantially planar lower surface spaced from the top surface and it is also configured to support the rack in one of the rack shelf portions or on the lower surface of the oven chamber. First and second walls extend between these first and second portions whereby the walls have a first dimension slightly greater than a height from the bottom surface of the oven chamber to a top of the bake element when the bake element is mounted above the lower surface.
