Oven Support Frame with Vertical Columns for Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional household cooking appliances face structural challenges as their load-carrying and aesthetic components are often the same, leading to inefficiencies in load distribution and potential for point failures, especially with thin sheet metal used for structural support.
Innovation Solution
The introduction of an elongated bead on vertical support columns and body-mounted hinge assemblies that engage with these columns, allowing for localized load distribution and increased strength without the need for the front panel to be structurally robust, using tabs and recesses for secure attachment and load transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of stationary object
If thin sheet metal is used for the front panel to reduce weight and cost, then the appliance becomes more cost-effective and lighter, but the structural strength and load-bearing capacity deteriorate
Solution Approach 1:
The invention separates the structural support function from the aesthetic enclosure function by introducing vertical support columns and an internal support frame. The front panel is divided into a cosmetic outer appearance and an internal support structure, allowing the front panel to be thin and lightweight while the support columns bear the structural loads.
Solution Approach 2:
Vertical support columns act as intermediary elements between the front panel and the load-bearing support frame. These columns receive loads from the front panel and transfer them to the support frame, enabling the front panel to be thin without compromising overall structural strength.
2Device complexity
If the front panel provides both aesthetic enclosure and structural support, then the design is simplified, but the load distribution becomes concentrated and point failures occur
Solution Approach 1:
The invention segments the load-bearing function from the enclosure function by introducing vertical support columns and a support frame. This distributes structural loads across multiple dedicated support elements rather than concentrating them in the front panel, improving reliability while adding moderate structural complexity.
Solution Approach 2:
The invention applies local quality by providing structural support only where needed - at the vertical columns and support frame locations - rather than requiring the entire front panel to be structurally robust. This allows thin panel material with localized reinforcement at critical support points.
3Device complexity
If the front panel carries the full load of the door and other components, then no additional support structure is needed, but the panel thickness and material requirements increase
Solution Approach 1:
The invention segments the load-carrying function from the front panel by introducing vertical support columns and a support frame. This allows the front panel to be thin cosmetic sheet metal while the support structure carries the full load of doors, racks, and other components.
Solution Approach 2:
Vertical support columns serve as intermediaries that transfer loads from the front panel to the internal support frame. This mediator structure enables the front panel to be thin material while still supporting heavy loads through the column-frame system.

AI summary
An oven includes a support frame for improved load distribution. The support frame includes a vertical support column that can include an elongated bead provided in a wall of the vertical support column. The support frame can also include a base rail. A bottom end of the vertical support column can terminate in an embossed pocked formed within the base rail.
