Fire pit ventilation insert ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Outdoor solid fuel fire pits face challenges in installation within permanent or decorative structures due to airflow requirements, often necessitating additional ventilation or compromising performance.
Innovation Solution
A fire pit insert ring system with a vent panel that provides airflow to the outer wall of the fire pit, allowing for installation in non-ventilated structures by suspending the fire pit and directing air flow inwardly, thus maintaining performance without external ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fire pits are installed in permanent or decorative structures, then structural integration is improved, but airflow to the fire pit is restricted
Solution Approach 1:
The vent panel extends downward from the surround in a vertical dimension, allowing air to be drawn from below the fire pit installation. This three-dimensional airflow path enables structures to be built around the fire pit while maintaining adequate air supply through the lower extension of the vent panel.
Solution Approach 2:
The vent panel acts as an intermediary component between the structure and the fire pit, providing a dedicated airflow path that mediates between the structural enclosure and the combustion air requirements. The panel with vent openings creates an intermediate airflow channel.
2Quantity of substance
If external ventilation ports are added to structures, then airflow is improved, but structural design freedom is reduced
Solution Approach 1:
The vent panel is merged with the surround to form an integrated insert ring assembly. This combination eliminates the need for separate external ventilation ports in the structure, as the vent panel itself provides the necessary airflow path while being part of the fire pit installation components.
Solution Approach 2:
The vent panel serves multiple functions: it provides airflow to the fire pit, extends downward to access air below the installation, and integrates with the surround to form a complete assembly. This multi-functionality reduces the need for additional structural modifications.
3Adaptability or versatility
If fire pits are suspended by the insert ring, then installation versatility is improved, but structural support requirements increase
Solution Approach 1:
The support ledges are positioned to contact the rim of the fire pit in a way that distributes the support force evenly around the circumference. This equipotential support arrangement allows the insert ring to suspend the fire pit effectively without requiring excessive localized support forces.

Function Achieved in This Case
Enables the installation of fire pits in various structures while ensuring adequate combustion air flow, reducing smoke and enhancing flame appearance, even in non-ventilated environments.
Implementation Method 1
The vent panel provide airflow into the installation and to an outer wall of the firepit
Data Source
AI summary
An insert ring that suspends a fire pit at least partially within an opening of a support structure, and provides ventilation into the support structure to an outer wall of the fire pit.
