Interchangeable Gas Burner Assembly With Automatic Flow Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas cooktop appliances have fixed burner configurations that limit user flexibility and require complex reconfiguration when changing burner sizes or locations, making it difficult to accommodate varying cooking needs and user preferences.
Innovation Solution
A cooktop appliance with interchangeable burners of different sizes and flame shapes, along with a gas flow switch that automatically adjusts gas flow to accommodate the selected burner, allowing for easy repositioning and size changes without reconfiguring igniters or fuel delivery systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed burner configuration is used in a gas cooktop, then the appliance structure is simple and reliable, but the user flexibility and adaptability to different cooking needs is limited
Solution Approach 1:
The burner assembly is divided into separable components including the burner body, igniter assembly, and fuel delivery system. This segmentation allows individual components to be independently replaced or reconfigured, enabling users to change burner configurations without replacing the entire cooktop assembly, thus improving adaptability while managing complexity.
Solution Approach 2:
The cooktop is designed with universal mounting interfaces and standardized connection points that allow different burner types and sizes to be installed in the same appliance. This multi-functionality enables a single cooktop to accommodate various burner configurations, enhancing user flexibility without requiring multiple specialized appliances.
2Adaptability or versatility
If burners of different sizes are positioned at fixed locations, then the appliance structure is simple, but the user cannot easily change burner locations to accommodate different cooking preferences or safety needs
Solution Approach 1:
The burner mounting system transitions from a static fixed configuration to a dynamic reconfigurable system. Burners can be easily removed and repositioned to different locations on the cooktop surface, allowing users to adapt burner placements to their specific cooking needs, safety requirements, or utensil sizes, thereby improving ease of operation and adaptability simultaneously.
3Adaptability or versatility
If the gas flow system is fixed for a specific burner size, then the fuel delivery system is simple and reliable, but the system cannot accommodate different burner sizes without reconfiguration
Solution Approach 1:
The gas flow system incorporates adjustable parameters including variable orifice sizes, controllable valve positions, and adaptable pressure regulation mechanisms. These parameter changes allow the fuel delivery system to be easily adjusted to match different burner sizes and gas consumption requirements, enabling adaptability without complex reconfiguration procedures.
Solution Approach 2:
The gas flow system is designed with self-adjusting features such as automatic flow regulation based on burner size detection or preset configuration settings. When a different burner is installed, the system automatically or semi-automatically adjusts gas flow parameters to the appropriate level, reducing the need for manual reconfiguration and simplifying the adaptation process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables flexible burner placement and size adjustments, enhancing user convenience and accommodating various cooking utensils while maintaining reliable operation and ease of use.
Implementation Method 1
The first gas flow switch may include a valve upstream of the fixed gas receptacle to selectively restrict gas flow upon engagement of the first gas flow switch with one of the first interchangeable burner or the second interchangeable burner.

AI summary
A cooktop and appliance is provided that may include a first hob zone having a fixed gas receptacle, a first interchangeable burner, a second interchangeable burner, and a first gas flow switch. The first interchangeable burner may be selectively positionable at the first hob zone and define a fuel output area. The second interchangeable burner may also be selectively positionable at the first hob and may define a fuel output area smaller than the fuel output area of the first interchangeable burner. The first gas flow switch may be disposed at the first hob zone to selectively engage one of burners. The first gas flow switch may include a valve upstream of the fixed gas receptacle to selectively restrict gas flow upon engagement of the first gas flow switch with one of the first interchangeable burner or the second interchangeable burner.
