Fire pit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable fire pits are not easily accessible for ash removal, require cumbersome methods for cleaning, and lack convenient transport and storage solutions.
Innovation Solution
A fire pit design featuring a quick release lock mechanism for the base portion, allowing easy access to an ash collection sump, collapsible structure for storage, and attachment of accessories like grill or hot plates, with a support assembly for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the base portion is made fixed and closed, then structural stability is improved, but ash removal accessibility deteriorates
Solution Approach 1:
The base portion is designed to be dynamically changeable between closed and open positions. The first and second plates can pivot between a closed position (providing structural stability during use) and an open position (enabling easy ash removal). The quick release lock mechanism enables this dynamic transformation, allowing the base to transition from a stable enclosed structure to an open configuration for maintenance access.
2Ease of operation
If the base portion is made removable, then ash removal accessibility is improved, but structural stability deteriorates
Solution Approach 1:
The base portion is segmented into separate first and second plates that can be independently manipulated. This segmentation allows the base to be opened by pivoting the plates while maintaining the overall structural integrity of the fire pit. The segmented design enables partial access for ash removal without requiring complete disassembly, thus preserving structural stability while improving accessibility.
3Adaptability or versatility
If the fire pit is made expandable for use, then functionality is improved, but storage convenience deteriorates
Solution Approach 1:
The side wall structure incorporates hinged connections that enable the fire pit to dynamically transform between an expanded configuration (providing full functionality for burning and cooking) and a collapsed configuration (enabling convenient storage and transport). The hinges allow smooth transitions between states, making the fire pit adaptable to different usage and storage needs without requiring complex assembly or disassembly procedures.
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 efficient ash removal, easy cleaning, convenient transport, and versatile use with accessories, improving user experience and functionality compared to prior designs.
Implementation Method 1
during normal use, upon actuating the quick release lock mechanism from the locked position to the unlocked position, the first and second plates are configured to move to the open position under gravity

AI summary
A fire pit comprising a body having a side wall structure. The body further comprises a base plate located adjacent a lower end portion of the side wall structure, and an opening defined by a perimeter of an upper end portion of the side wall structure. Together, the side wall structure and the base plate form a fire pit chamber. The lower end portion of the side walls and the base plate form a collection sump for collecting and retaining ash that is generated during use. The lower portion of two opposite side walls and and the base plate are tapered downwards towards the center of the base plate to facilitate collection of ash.
