Solution Overview
Problem
Existing alcohol fuel gasification devices for fireplaces suffer from non-uniform heating, leading to unstable and potentially explosive boiling of liquid fuel, and safety hazards due to close integration with burners.
Innovation Solution
A gasification device with a gasification chamber featuring electric heating elements enclosed between the chamber and a base, cooling fins for uniform heating, a liquid level control system with probes for precise fuel management, and a controller for regulating heating and fuel supply, along with a non-metal gas outlet pipe to prevent heat transfer from the burner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the electric heating device directly heats the housing of the gasification chamber with a simple shape, then the device structure is simple, but the heating area is insufficient and heating is non-uniform causing explosive boiling
Solution Approach 1:
The heating system is segmented into multiple electric heating elements (first heating element on the base, second heating element on the inner wall) instead of a single heating source. The gasification chamber is divided into functional zones with different heating characteristics, allowing uniform heating across the entire fuel volume and preventing localized overheating that causes explosive boiling.
Solution Approach 2:
Different regions of the gasification chamber are provided with different heating characteristics - the base area receives heating from the first heating element while the inner wall area receives heating from the second heating element. This local differentiation of heating quality ensures uniform temperature distribution throughout the liquid fuel, resolving the heating uniformity issue while maintaining structural simplicity.
2Volume of moving object
If the gasification chamber is integrated with burners or arranged very close to burners, then the device structure is compact, but heat from flames returns to the gasification chamber affecting gasification rate and causing safety hazards
Solution Approach 1:
The gasification chamber is extracted and separated from the burner assembly, positioned at a distance from the burners. This separation removes the harmful thermal feedback from the burners to the gasification chamber, stabilizing the gasification rate and preventing explosive boiling, while the overall device remains compact through optimized spatial arrangement.
3Ease of manufacture
If the gasification chamber has a simple housing shape for accommodating liquid fuel, then the manufacturing is easy, but the heating area is not sufficiently large leading to non-uniform gasification
Solution Approach 1:
The heating area is expanded by utilizing multiple dimensions - heating elements are placed on the base (horizontal dimension) and on the inner wall (vertical dimension). This multi-dimensional heating arrangement increases the total heating surface area without complicating the external housing shape, maintaining ease of manufacture while achieving uniform heating throughout the liquid fuel volume.

AI summary
A device includes a chamber, a lid, heating elements, a base, and a controller. The chamber is a structure containing a inner cavity, the base is below the chamber, and the heating elements are between a lower surface of the chamber and the base. Cooling fins are in the inner cavity connected to a lower surface of the inner cavity and are close to the heating elements. Channels for liquid circulation are provided between fins and between the fins and an inner wall of the chamber. The lid is above the chamber and seals the inner cavity so that the inner cavity is closed. Gas outlet ports are on the lid. Due to the cooling fins, when the heating elements heat liquid fuel in the inner cavity, the liquid fuel is heated uniformly, and the gasification process is stable and controllable, avoiding explosive boiling of the liquid fuel.
