Fire pit ventilation features
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor fire pits face challenges in installation within permanent or decorative structures without compromising design or performance, as they often require additional ventilation ports or diminish performance when installed in non-ventilated spaces.
Innovation Solution
A fire pit insert ring system that includes a surround and a vent panel with airflow openings, allowing for ventilation into the fire pit even when installed in non-ventilated structures, by suspending the fire pit and providing airflow through rebated portions and support ledges, ensuring adequate combustion air flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fire pit is installed in a permanent or decorative structure without external ventilation ports, then the design flexibility and structural integration are improved, but the combustion performance deteriorates due to insufficient airflow
Solution Approach 1:
The patent transitions from horizontal/external ventilation (requiring external ports in the structure) to vertical/downward ventilation (through the floor or lower structure). The air intake system directs airflow from below the fire pit, utilizing the vertical dimension to bypass the need for external side ports while maintaining adequate oxygen supply for combustion
Solution Approach 2:
The patent introduces an intermediary air intake system consisting of vents, baffles, and flow directors that mediate between the external environment and the combustion chamber. This intermediary system channels air through the structure's floor or lower sections, allowing integration with permanent structures while ensuring proper airflow without requiring direct external access points at the fire pit level
2Reliability
If additional external ventilation ports are provided for the fire pit, then the combustion performance is maintained, but the design freedom and aesthetic integration of the structure are reduced
Solution Approach 1:
The patent extracts the ventilation function from the fire pit assembly itself and relocates it to the structural foundation or lower sections. By separating the air intake function from the visible fire pit structure, the system maintains combustion performance while eliminating the need for external ventilation ports that would compromise aesthetic integration and design freedom
Solution Approach 2:
The patent employs intermediary components such as floor vents, bass traps, and air flow directors that are concealed within or integrated into the structural elements. These intermediaries provide the necessary airflow path without requiring visible external ports on the fire pit or其主要结构, thereby maintaining both performance and aesthetic integration
3Reliability
If the fire pit is suspended within the installation using the insert ring, then the airflow distribution is improved, but the structural support complexity increases
Solution Approach 1:
The insert ring serves multiple functions simultaneously: it provides structural support for suspending the fire pit, creates the necessary air intake openings, and directs airflow distribution. By combining these functions into a single component, the system achieves improved airflow without proportionally increasing structural support complexity
Solution Approach 2:
The patent merges the support structure with the ventilation system. The insert ring that suspends the fire pit is integrated with air intake baffles and flow directors, so that the same structural element that provides support also manages airflow. This consolidation reduces the need for separate complex support mechanisms while ensuring proper air distribution

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.
