Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decorative stoves fail to achieve a vivid viewing effect of flame burning on water, lacking the desired ornamental impact.
Innovation Solution
A decorative gas stove design featuring a stove body with a cavity, a water tank with air outlet holes, an ignition portion, and an anti-backflow structure to deliver gaseous fuel to the water surface for ignition, along with a solenoid valve and pulse igniter for controlled flame production, and a viewing glass for safety and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If gaseous fuel is supplied to the water surface for burning, then the ornamental flame effect is improved, but water may flow back into the supply pipe causing safety issues
Solution Approach 1:
An anti-backflow structure is introduced as an intermediary component between the water tank and supply pipe. This structure includes a movable plugging portion that automatically blocks the air outlet holes when water level rises, preventing water from flowing back into the supply pipe while allowing normal gas flow during operation
Solution Approach 2:
The movable plugging portion is designed to automatically respond to water level changes without external control. When water flows back and contacts the plugging portion, it is pushed to block the air outlet holes, creating a self-activating safety mechanism that prevents further backflow
2Reliability
If a movable plugging portion is added to prevent backflow, then system safety is improved, but device complexity increases
Solution Approach 1:
The movable plugging portion is designed to automatically respond to water level changes without external control. When water flows back and contacts the plugging portion, it is pushed to block the air outlet holes, creating a self-activating safety mechanism that prevents further backflow
Solution Approach 2:
The anti-backflow function is extracted as a separate, independent movable plugging portion that can be easily added to the existing gas supply structure. This modular approach allows backflow prevention to be implemented without redesigning the entire system
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
The solution enables gaseous fuel to burn on the water surface, creating an ornamental flame effect while preventing backflow and ensuring safety through controlled ignition and insulation, thereby enhancing the decorative appeal.
Implementation Method 1
gaseous fuel flowing to a water surface through the air outlet holes... igniting the gaseous fuel... burning on the water surface
Implementation Method 2
the movable plugging portion being pushed from the plugging position to the avoidance position by the gaseous fuel when the energy device outputs the gaseous fuel into the gas supply cavity
Implementation Method 3
the reset portion being configured to push the movable plugging portion from the avoidance position to the plugging position when the energy device stops supplying gaseous fuel
