Multi-Mode Burner Group Control Using Single Configurable Selector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cooking appliance manufacturing, the traditional system requires multiple control knobs for each burner, leading to increased costs and a cluttered user interface, while digital gas systems allow for fewer control knobs due to their flexibility in placement and operation.
Innovation Solution
A single configurable control selector assembly that can be assigned to different burners, featuring a burner status display and multiple operating modes, allowing for collective or individual control of burners, and includes an ignition function for enhanced safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual control knobs are assigned to each burner, then each burner can be controlled independently, but the number of control knobs increases leading to increased costs and cluttered user interface
Solution Approach 1:
A single control knob is designed to control multiple burners through different operational modes. The control knob can operate burners individually or collectively based on selected modes, making one control element perform the function of multiple traditional knobs while maintaining ease of operation through mode selection
2Adaptability or versatility
If digital gas valves are used with remote control knobs, then control knob placement becomes flexible, but the system requires complex signaling mechanisms between knobs and valves
Solution Approach 1:
A controller acts as an intermediary between the control knob and digital gas valves. The controller receives signals from the control knob and manages the communication with multiple valves, simplifying the overall system architecture while maintaining placement flexibility and reducing direct connection requirements
3Device complexity
If a single control selector is used for multiple burners, then the number of controls is reduced and interface is simplified, but the ability to control each burner individually may be compromised
Solution Approach 1:
The control system dynamically switches between different operational modes (individual burner control, collective burner control, etc.) based on user selection. This dynamic mode switching allows a single control knob to adapt its function to provide either individual or collective control as needed, maintaining versatility while reducing the number of physical controls

AI summary
A cooking appliance and system therefor utilize a burner group capable of operating in multiple modes such that gas cooktop burners disposed in the burner group may be collectively or individually controlled in different modes.
