Fire Pit Burner Layout for Uniform Flames and Water Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fire pit burners often produce uneven and unnatural-looking flame patterns, requiring additional media to conceal the burner design, and struggle with water drainage and moisture accumulation.
Innovation Solution
A fire pit burner design featuring an inlet hub connected to a fuel supply spoke and a burner tube with specific angled and curved configurations, including top and side holes, promotes uniform fuel and flame distribution by minimizing void areas and using a sloping design to drain water, resulting in a natural-looking flame pattern.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional fire pit burners use traditional burner designs, then the structure is simple, but the flame pattern is uneven and unnatural-looking
Solution Approach 1:
The burner is divided into multiple functional components: a central hub, multiple spokes extending from the hub, and burner tubes positioned at the ends of the spokes. Each spoke contains multiple holes distributed along its length, and each burner tube has holes at multiple positions (top, bottom, and side). This segmentation allows fuel to be delivered to numerous distributed outlets, creating uniform flame distribution across the entire burner structure, eliminating the uneven flame patterns of conventional single-tube designs.
Solution Approach 2:
The burner design transitions from a conventional single-plane or simple linear configuration to a three-dimensional radial structure. The spokes extend outward from the central hub in multiple directions, positioning burner tubes at various radial distances and angles. This spatial distribution across multiple dimensions ensures uniform fuel delivery and flame emission in all directions, creating a natural-looking circular flame pattern that fills the fire pit evenly.
2Reliability
If conventional fire pit burners use horizontal or flat designs, then manufacturing is simple, but water drainage and moisture accumulation are problematic
Solution Approach 1:
The burner components are designed with asymmetric slopes rather than symmetric horizontal surfaces. The spokes are positioned at angles relative to the horizontal plane, and the burner tubes are oriented to create sloped surfaces. This asymmetric angular configuration causes water and moisture to naturally drain downward along the inclined surfaces toward collection points, preventing water accumulation and corrosion issues that plague flat, horizontal burner designs.
Solution Approach 2:
The central hub is designed with a curved, dome-like upper surface rather than a flat top. This curved geometry facilitates water shedding by creating continuous slopes that direct water away from the hub center toward the spoke connections and drainage points. The curvature eliminates flat surfaces where water could pool, enhancing the overall drainage effectiveness of the burner system.
