Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gas burners lack the ability to control flame shape and direction, limiting both functional and aesthetic options for users.
Innovation Solution
A gas burner design featuring a combustion chamber with a circumferential crenellated wall and switchable burner caps that allow for the selection between an inner flame and a vertical flame state, achieved by directing fuel exit ports inwardly or upwardly through the use of an inner flame burner cap and a vertical flame burner cap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional gas burner design is used, then the burner structure is simple, but the flame shape and direction cannot be controlled
Solution Approach 1:
The burner is divided into multiple functional components: a base structure, a cap assembly with selectable configurations, and fuel delivery systems. This segmentation allows the flame control function to be added through the modular cap assembly without redesigning the entire burner, thus improving adaptability while managing complexity.
Solution Approach 2:
The burner cap is designed with multi-functionality, capable of being configured in different positions and orientations to produce various flame shapes and directions. This single component performs multiple functions (controlling flame shape, direction, and distribution) rather than requiring separate devices for each function, improving versatility without proportionally increasing overall device complexity.
2Productivity
If flame direction is not controlled, then the burner structure is simple, but heat loss increases and cooking efficiency decreases
Solution Approach 1:
The burner cap is designed to be dynamically adjustable, allowing users to change its position and orientation based on cooking requirements. This dynamic adjustment capability enables optimal flame direction control for different cooking tasks, improving cooking efficiency without requiring a complex automated control system.
Solution Approach 2:
The burner incorporates a manual adjustment mechanism that allows users to independently control flame direction and shape without requiring external assistance or complex automated systems. This self-service approach improves cooking efficiency through user control while keeping the device complexity relatively low.
3Adaptability or versatility
If multiple flame configurations are added, then functional and aesthetic options are improved, but the device complexity increases
Solution Approach 1:
Multiple flame configuration capabilities are merged into a single integrated cap assembly. By combining various flame control functions (directional control, shape modification, distribution patterns) into one unified component, the system achieves high adaptability while avoiding the complexity of multiple separate control mechanisms.
Solution Approach 2:
The burner cap utilizes spatial dimensionality to create different flame configurations. By adjusting the cap's position, orientation, and angular settings in three-dimensional space, multiple flame shapes and directions are achieved without adding numerous mechanical components. This dimensional approach provides versatility while maintaining relatively simple device architecture.

Implementation Method 1
A plurality of fuel exit ports is disposed in the circumferential crenellated wall, the fuel exit ports being directed generally inwardly toward the combustion chamber and upwardly from the bottom of the combustion chamber
Implementation Method 2
A vertical flame burner cap is selectively and alternatively coupled to the top portion of the circumferential crenellated wall to define a plurality of fuel exit ports directed generally upwardly to create the vertical flame projected up from the gas burner
Implementation Method 3
a combustion chamber having a bottom and a circumferential crenellated wall

AI summary
A gas burner having a switchable flame includes a combustion chamber having a bottom and a circumferential crenellated wall with a plurality of fuel exit ports disposed in the circumferential crenellated wall. The fuel exit ports are directed generally inwardly toward the combustion chamber and also upwardly from the bottom of the combustion chamber. The gas burner additionally includes a burner base and a swirl spreader disposed above the burner base which defines a top portion of the circumferential crenellated wall of the combustion chamber. An annular burner cap set includes an inner flame burner cap and a vertical flame burner cap where the inner flame burner cap and the vertical flame burner cap are selectively and alternatively positioned on the circumferential crenellated wall to define an inner flame state and a vertical flame state, respectively, of the fuel exit ports.
