Modular Ornametal Flame System Using Venturi Jets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire pit systems produce blue, intense flames that lack the natural ambiance and safety of a wood fire, are not customizable, and have inefficient gas distribution leading to small, low-volume flames with poor heat and light distribution.
Innovation Solution
A system using brass pipe sections and connectors to support jets that utilize the Venturi effect for mixing gas and air, allowing for adjustable flame patterns and positions to create a wide, low-heat, ornamental flame with improved light and heat distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If gas is ejected from a jet at high speed, then the flame produces intense heat and bright light, but the flame appears rushed and lacks natural movement, and produces inordinate amounts of heat
Solution Approach 1:
The system divides the gas delivery into multiple separate jets distributed across the fire pit, rather than a single concentrated jet. Each jet operates at lower individual flow rates, producing flames that are brighter collectively but less intense individually, creating natural movement and reducing excessive heat concentration in one location.
Solution Approach 2:
The patent positions jets at specific locations and angles to create varying flame characteristics in different zones. Some jets are positioned to create rising flames, others to create lateral flames, producing a differentiated flame pattern that mimics natural wood fire behavior with varied movement and temperature distribution.
2Power
If a single manifold with closely positioned nozzles is used, then heating efficiency is maximized, but the flame pattern is concentrated and lacks voluminous appearance
Solution Approach 1:
The system transitions from a two-dimensional concentrated manifold to a three-dimensional distributed jet arrangement. Jets are positioned at various heights, angles, and locations throughout the fire pit structure, creating voluminous flame patterns that extend in multiple spatial dimensions rather than confined to a single plane.
Solution Approach 2:
Multiple identical or similar jet assemblies are distributed throughout the fire pit, each producing a copy of the flame effect. This replication of flame sources across multiple locations creates a cumulative voluminous appearance while maintaining efficient gas utilization at each individual jet.
3Ease of manufacture
If standard size fireplaces or fire pits are used, then installation is simplified, but the system cannot be customized for different architectural or aesthetic needs
Solution Approach 1:
The fire pit system is divided into modular components including separate gas delivery lines, individual jet assemblies, and configurable support structures. This segmentation allows the system to be adapted to various fireplace and fire pit sizes and shapes by selectively assembling and positioning components, while maintaining relatively simple installation procedures.
Solution Approach 2:
The system incorporates adjustable elements such as configurable jet positions, variable gas flow rates, and adaptable support structures that can be modified during installation to match different architectural requirements. This dynamic configurability enables customization without requiring completely different system designs.

AI summary
A modular burner system includes a nipple elongated along an axis and a plurality of jets connected to the nipple. The jets are spaced from each other along the axis. Each jet connected to the nipple has a jet axis and is elongated from the nipple along the jet axis. Each jet connected to the nipple has an exit on the jet axis spaced from the nipple to release fuel to fuel a flame at the exit. The jet axis of at least one of the jets connected to the nipple is at a first angle relative to the axis and the jet axis of at least one of the jets connected to the nipple is at a second angle relative to the axis different than the first angle.
