Portable Fire Pit Grill Cart With Locking Pivot Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable recreation devices typically consist of separate units for barbecuing grills and fire pits, making it difficult to transport both to remote locations simultaneously.
Innovation Solution
A portable device that integrates a fire pit and a barbecuing grill coupled to a transport cart, featuring a frame with a handle, lateral support portions, and wheels, allowing for easy movement and configuration between stowed and deployed positions, with a gas supply system for the fire pit and grill, and a locking mechanism to prevent pivotal movement of the fire pit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If portable grills and fire pits are sold as separate units, then each unit can be optimized for its specific function, but it becomes difficult to transport both to remote locations simultaneously
Solution Approach 1:
The patent combines a fire pit and a grill into a single integrated portable device. The fire pit assembly and grill assembly are structurally merged and mounted on a common cart frame, allowing both functions to be transported together as one unit while maintaining their individual operational capabilities
Solution Approach 2:
The integrated device serves multiple functions: it can operate as a fire pit for warmth and ambiance, as a grill for cooking, and as a combined unit where the grill can be positioned over the fire pit for enhanced cooking performance. This multi-functionality resolves the contradiction by providing versatility without requiring separate transport of multiple devices
2Ease of operation
If the fire pit is pivotally coupled to the frame for easy positioning, then the fire pit can be easily adjusted and stored, but unwanted pivotal movement can occur during transport
Solution Approach 1:
The fire pit assembly is pivotally coupled to the frame, allowing it to be dynamically adjusted between different positions (e.g., over the fire pit, beside it, or stored). This dynamic coupling enables easy repositioning during use while the pivotal mechanism itself provides adaptability
Solution Approach 2:
A locking mechanism is provided that can be engaged before transport to prevent unwanted pivotal movement. This preliminary action of locking ensures stability during transport, while the ability to unlock allows for easy repositioning during use, thus resolving the contradiction between flexibility and stability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient and simultaneous use of both fire pit and grill at remote locations, such as beaches or campsites, with the ability to easily transport and set up the device, ensuring stability and safety through the use of wheels and a locking mechanism.
Implementation Method 1
a fire pit (22) coupled to the frame (12)... adapted to receive wood or other fuel, or alternatively, adapted to receive a gas supply
Implementation Method 2
a grill (38) coupled to the frame (12)... adapted for grilling food
Implementation Method 3
a grill (38) coupled to the frame (12)... adapted for grilling food

AI summary
A portable device which integrates the functionalities of a fire pit and a barbecuing grill. The fire pit and grill are coupled to a transport cart to facilitate movement of the fire pit and grill to a desired location. In this respect, the transport cart may be configured to allow a user to transport the device across sand (e.g., when using the device at a beach) or across a parking lot (e.g., when using the device while tailgating in a stadium parking lot). Thus, the device easily allows for enjoyment of both a fire pit and a grill in remote locations.
