Pivoting Barbecue Oven Assembly With Food-Warming Casing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current outdoor cooking appliances lack a combination of a barbecue and an oven in a single, portable unit where both components can be used independently and efficiently, with inadequate temperature control for maintaining cooked foods.
Innovation Solution
A multifunction outdoor cooking set integrating a barbecue and a pizza, bread, or tarte flambée oven, where both are heated by a single hearth and the oven is pivotally mounted to allow easy access to the barbecue, featuring a refractory stone-lined oven and a temperature-maintaining box for keeping food warm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a barbecue and an oven are combined in a single appliance heated by one hearth, then space efficiency and portability are improved, but safety conditions deteriorate when one part is still hot and the other needs to be used
Solution Approach 1:
The oven is mounted on a pivoting mechanism that allows it to move between a horizontal cooking position and a vertical storage position. This dynamic configuration enables the oven to be tilted back when the barbecue is in use, preventing contact with hot surfaces and ensuring safe operation of both components in sequence
Solution Approach 2:
The combined appliance is divided into two functional modules: a barbecue section with its own cooking surface and an oven section with refractory stone lining. Each module can be independently accessed and used by pivoting the oven away from the barbecue area, allowing separate operation while maintaining a compact integrated structure
2Adaptability or versatility
If the oven is mounted horizontally above the barbecue, then cooking functionality is improved, but access to the barbecue cooking surface is blocked
Solution Approach 1:
The oven is mounted on a pivoting mechanism that allows it to move between a horizontal cooking position and a vertical storage position. When the barbecue needs to be used, the oven can be tilted back to a vertical position, clearing access to the barbecue cooking surface while maintaining full cooking functionality when needed
3Area of stationary object
If cooked food is placed on a raised grill away from the hearth, then space utilization is improved, but temperature control is lost causing food to cool or dry out
Solution Approach 1:
A temperature-maintaining box serves as an intermediary device between the heat source and the food. This box, equipped with a heating element and thermostat control, provides a controlled thermal environment that maintains food at optimal serving temperatures without direct exposure to the barbecue flames, preventing both overheating and excessive cooling
Solution Approach 2:
The temperature-maintaining box incorporates a thermostat that continuously monitors the internal temperature and provides feedback control to the heating element. This feedback mechanism automatically adjusts heating power to maintain the desired temperature range, preventing food from cooling down or drying out while maximizing space utilization
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary
The invention relates to a multi-functional outdoor cooking assembly formed by an oven (3) pivotally mounted on a barbecue (2) by means of a pivot joint (39). The barbecue (2) comprises an ash pan (18), a firebox (13) and a cooking surface (29), while the oven (3) includes a cooking base (41) made from firestone (42) and a door (44) in the front face (43) thereof. The chamber (40) of the oven (3) has a double wall (51) that is open in the lower portion thereof and connected to a chimney (52) that is mounted on the upper portion of the oven (3) and connected to the firebox (13) of the barbecue (2). The cooking assembly comprises at least one temperature-maintaining casing (74) to be mounted, by means of one of its sidewalls (76), on a hot side of the barbecue (2). Said casing (74) comprises a thermometer (91) and an air exhaust port (92) that allows the hot air contained therein to escape.
