Fire Display Device Vertical Flame Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional fire display devices face challenges in creating highly visible flames from a distance, as they often produce low, spread-out flames due to pilot light ignition configurations that result in a whipping effect, making it difficult to achieve defined ignition events and theatrical flame shapes.
Innovation Solution
The solution involves directing at least one stream of flames vertically from a center housing within the fire display device, with additional gaseous fuel streams injected via gaseous fuel injectors positioned outside the housing, which increases flame height and reduces the whipping effect, allowing for more visible and controlled flame displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If traditional pilot light ignition configuration is used, then the device structure is simple, but the flame height is low and the flame is spread out making it difficult to see from distance
Solution Approach 1:
The ignition system is segmented into two distinct parts: a centralized ignition source (pilot light or ignitor in center housing) and distributed fuel injection points (multiple gaseous fuel injectors positioned outside the center housing). This segmentation allows the ignition source to remain simple while the fuel delivery system creates multiple vertical flame streams, resolving the contradiction between simple ignition configuration and tall visible flames.
Solution Approach 2:
A center housing is introduced as an intermediary structure that contains the ignition source and positions it centrally relative to multiple fuel injectors. This intermediary component organizes the ignition process and directs fuel streams vertically upward, enabling tall flames without requiring the ignition source itself to be complex or positioned at multiple locations.
2Stability of the object's composition
If traditional pilot light ignition is used, then the ignition process is simple, but the whipping effect occurs causing flames to be affected by external factors like airflow
Solution Approach 1:
The fuel delivery system is segmented into multiple independent injectors positioned outside the center housing, each delivering fuel to a common ignition zone. This segmentation allows the ignition source to remain simple while the distributed fuel injection points create multiple vertical flame streams that are more resistant to whipping effects from airflow, as the vertical orientation and multiple streams provide stability.
Solution Approach 2:
The fuel injection parameters are changed by positioning multiple fuel injectors outside the center housing and directing fuel streams vertically upward. This parameter change in fuel delivery configuration, combined with the centralized ignition source, creates a more stable flame structure that resists external airflow effects while maintaining a relatively simple ignition system.
3Manufacturing precision
If traditional ignition configuration ignites gaseous fuel close to burner pan, then the ignition timing is simple, but the flames are low and spread out rather than forming defined ignition events
Solution Approach 1:
The center housing serves as an intermediary that positions the ignition source centrally and directs multiple fuel streams from outside injectors toward a common ignition zone. This intermediary structure enables defined ignition events where multiple gaseous fuel streams are ignited at substantially the same time, creating tall vertical flames rather than low spread-out flames, while keeping the ignition mechanism itself relatively simple.
Solution Approach 2:
The fuel injection system is arranged in a vertical dimension with multiple injectors positioned outside the center housing and directing fuel streams upward. This vertical arrangement, combined with centralized ignition, creates defined ignition events with tall flames that are visually distinct and theatrical, transforming the traditional horizontal flame spread pattern into a vertical flame structure.
4Illumination intensity
If multiple gaseous fuel streams are ignited at substantially the same time, then the theatrical effect is enhanced, but the ignition synchronization becomes more difficult to achieve
Solution Approach 1:
The center housing acts as an intermediary that集中s the ignition source and directs multiple fuel streams from outside injectors toward a common ignition zone. This intermediary structure naturally synchronizes the ignition of multiple fuel streams as they converge at the same location, enabling simultaneous ignition and enhanced flame visibility without requiring complex multi-point ignition synchronization systems.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration results in taller, more visible flames that are less affected by external factors, enhancing the entertainment and theatrical effect of fire displays by providing a more consistent and visually appealing flame structure.
Implementation Method 1
a pilot light and an ignitor positioned within the center housing and configured to ignite the stream of gaseous fuel to produce flames
Implementation Method 2
Additional gaseous fuel streams may then further be directed towards the at least one stream of flames via gaseous fuel injectors positioned outside of the center housing

AI summary
Systems and methods for a fire device forming at least one stream of flames within a center housing, and directing the at least one stream of flames through one or more apertures formed into an upper surface of the center housing and vertically above the center housing. In some examples, one or more gaseous fuel streams are injected towards the at least one stream of flames and above the center housing via fuel injection ports positioned outside of the center housing.
