Portable Gas Stove Burner Control With Flame-Out Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor portable gas stoves lack comprehensive control over gas transmission, leading to potential safety hazards due to uncontrolled gas supply and vulnerability to wind extinguishing the flame.
Innovation Solution
An outdoor portable gas stove design featuring an annular gas passage in the burner, a control valve in the gas pipeline, and a flame-out protection device, along with an electronically controlled ignition system and adjustable foot bracket, allowing for controlled gas flow and automatic stop of gas supply when the flame is extinguished.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If gas directly connects with burner to reduce volume, then portability is improved, but gas transmission control capability deteriorates
Solution Approach 1:
The gas pipeline is segmented into internal and external portions, with the control valve positioned on the external pipeline. This segmentation allows the control mechanism to be separated from the compact burner assembly, enabling effective gas flow control while maintaining a small overall stove volume.
Solution Approach 2:
A control valve is introduced as an intermediary device between the gas source and the burner. This intermediary component enables precise control of gas transmission, allowing the user to regulate gas flow and adjust firepower, while the valve's compact design does not significantly increase the overall stove volume.
2Reliability
If wind shields are added around burner to prevent wind extinction, then flame protection is improved, but device complexity increases
Solution Approach 1:
The stove cover serves multiple functions: it protects the burner from wind, supports cooking utensils, and provides structural framework. By making the existing stove cover multi-functional rather than adding a separate wind shield, the design achieves flame protection without increasing device complexity.
Solution Approach 2:
The wind protection function is merged with the stove cover structure. The stove cover simultaneously acts as a wind barrier and a support structure for cooking utensils, combining multiple functions into a single component to avoid increasing overall complexity.
3Reliability
If flame-out protection device is added to prevent gas leakage, then safety is improved, but device complexity increases
Solution Approach 1:
The flame-out protection device operates on a feedback principle where the flame's presence or absence automatically controls the gas supply. When the flame is detected (through thermal or electromagnetic sensing), the valve remains open; when the flame goes out, the system automatically closes the valve to stop gas flow, providing safety through automatic feedback control without requiring complex manual intervention systems.
4Ease of operation
If control valve is added to adjust firepower, then controllability is improved, but device complexity increases
Solution Approach 1:
The control valve is designed with a simple manual operation mechanism that allows users to easily adjust gas flow and firepower through direct manipulation. The valve's design enables self-service operation without requiring complex control systems, electronic components, or multiple adjustment mechanisms, maintaining simplicity while providing effective firepower control.
