Foldable Barbecue Oven Shelf and Roller Base for Portability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current barbecue ovens with object placement shelves are not portable due to their large volume when not in use and are prone to damage or pollution, as the shelves cannot be folded.
Innovation Solution
A combined type of barbecue oven design featuring a foldable object placement shelf with an X-shaped supporting structure, reinforced edges, and a coil base frame with rollers, allowing the oven to be compactly stored and easily moved by inclining the coil base frame for dragging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the object placement shelf is fixed and cannot be folded, then the shelf provides stable support for objects, but the overall volume of the barbecue oven becomes large and it becomes non-portable
Solution Approach 1:
The object placement shelf is designed to be dynamically adjustable between a horizontal extended position for use and a vertical folded position for storage. The shelf connects to the supporting structure via rotation shafts, allowing it to change its spatial configuration from a stable horizontal plane to a compact vertical arrangement, thus resolving the contradiction between stability during use and compactness during storage.
Solution Approach 2:
The shelf system is segmented into multiple components: the object placement plate, reinforced edges with rotation shafts, and the supporting structure with vertical slots. This segmentation allows the shelf to be folded vertically while maintaining structural integrity through the reinforced edges and rotation shafts, enabling both stability during use and compact storage.
2Device complexity
If the object placement shelf is fixed and cannot be folded, then the shelf structure is simple, but the barbecue oven becomes non-portable and the shelf is prone to damage or pollution
Solution Approach 1:
The shelf incorporates rotation shafts at the reinforced edges that enable dynamic folding motion. This dynamic mechanism allows the shelf to transition between horizontal and vertical positions, providing portability while maintaining relatively simple construction through the use of basic rotational joints and reinforced edge structures.
3Volume of moving object
If the object placement shelf is made foldable, then the barbecue oven becomes portable and compact, but the shelf mechanism becomes more complex
Solution Approach 1:
The folding mechanism uses simple rotation shafts connected to vertical slots in the supporting structure. The rotation shafts allow the shelf to fold vertically while the slot constraints guide the motion, creating a compact portable design without requiring complex mechanisms such as hinges, springs, or motorized systems.
Solution Approach 2:
The vertical slot in the supporting structure acts as an intermediary constraint that guides the rotation shaft's motion. This slot-rotation shaft combination provides a simple yet effective folding mechanism that enables compact storage while maintaining structural support, avoiding the need for more complex folding mechanisms.
4Area of moving object
If the object placement shelf is extended horizontally, then the shelf provides adequate support area for objects, but the barbecue oven volume increases
Solution Approach 1:
The shelf dynamically changes its horizontal area by folding vertically when not in use. When extended horizontally, it provides adequate support area for barbecue objects. When folded vertically, it reduces the horizontal footprint and overall volume, allowing the barbecue oven to be compact and portable while maintaining sufficient shelf area during operation.

AI summary
A combined type of barbecue oven comprises a barbecue oven and a coil base frame provided with rollers, the barbecue oven is mounted on the coil base frame, wherein the two ends of the supporting structure of the barbecue oven are provided with a foldable object placement plate. The object placement plate of the barbecue oven is foldable; therefore the occupying space is small. Moreover, the volume of the whole oven body is small, which is convenient for moving. When being moved in a short distance, the barbecue oven does not need to be moved, it only requires to mount the coil base frame with an inclined side and provided with the rollers and the barbecue oven on the coil base frame, so that the whole combined type of barbecue oven can be dragged to move; the barbecue oven is conveniently used, healthful, and suitable for being popularized.
