Foldable Grill Cart Assembly for Tool-Free Setup and Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grill systems are often difficult to assemble, require numerous components, and take up significant space, especially when in a folded configuration, lacking portability and flexibility compared to permanent outdoor installations.
Innovation Solution
A grill system with a foldable cart that can transition between an upright and folded state, featuring a burner box detachably coupled to the cart, allowing for easy assembly and disassembly without tools, and a compact design that reduces storage and transportation volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a grill system uses a foldable cart design, then portability and storage space are improved, but assembly complexity and structural stability may worsen
Solution Approach 1:
The grill system is divided into separate modular components including the burners, cooking grates, and cart frame. These segments can be easily assembled and disassembled without tools, allowing the grill to be compact for storage yet functional when assembled. The modular design directly addresses the contradiction by enabling simple assembly while maintaining portability.
Solution Approach 2:
The cart frame incorporates foldable sides that can transition between an extended cooking position and a collapsed storage position. This dynamic structure allows the grill to adapt its volume based on usage needs, reducing storage volume while maintaining structural integrity during cooking operations.
2Volume of moving object
If a grill system uses a foldable cart design, then portability and storage space are improved, but structural stability may worsen
Solution Approach 1:
The foldable cart sides are designed to be rigid when extended for cooking, providing structural stability during use. When collapsed for storage, the reduced volume is achieved while the frame maintains its shape through the base structure and side frame geometry, balancing stability with compactness.
Solution Approach 2:
The side frames are positioned at different distances from the base plane, creating an asymmetric structure that optimizes both stability and compactness. This asymmetric design allows the folded sides to nest efficiently while the extended configuration provides a stable cooking surface.
3Ease of operation
If past foldable stands are used, then portability is improved, but set-up steps and space consumption worsen
Solution Approach 1:
The burners and cooking components are pre-assembled as complete modules that can be placed directly onto the cart base. This segmentation eliminates the need for complex step-by-step assembly of individual components, reducing set-up time while maintaining portability through the modular design.
Solution Approach 2:
The burners, cooking grates, and other components are pre-configured and ready for immediate installation on the cart. This preliminary preparation allows users to quickly assemble the complete grill system without needing to perform complex assembly steps during setup.

AI summary
In an embodiment, a grill is provided. The grill can include a grill cart and a burner box. The grill cart configured to be transitioned between an upright state and a folded state. The coupling between a first side frame and a base is located in a first plane that is substantially parallel with a plane defined by a bottom plate of the base, and the coupling between a second side frame and the bottom plate of the base is located in a second plane that is substantially parallel with the plane defined by the bottom plate. The first plane is located a first distance away from the plane defined by the bottom plate and the second plane is located a second distance away from the plane defined by the bottom plate. The first distance is not equivalent to the second distance. Other embodiments are also included herein.
