Innovation Solution

A fireplace design featuring a burner with horizontal and inclined portions forming a three-dimensional geometric space, combined with a gasification device, liquid supply, and control system to create a 3D flame effect, using simulated solid fuels and decorative elements to enhance realism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If liquid fuel is burned directly in a combustion tank, then the flame burns in a straight line, but the flame lacks depth and graduation, producing a rigid and visually unappealing effect

Engineering Contradiction:
Improveflame shapeVSAvoidburner structure
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The burner is divided into multiple segments including a combustion chamber main body, multiple horizontal portions, and multiple inclined portions. Each segment contains flame holes that emit flames in different directions, collectively forming a three-dimensional flame effect that simulates real firewood burning.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The burner structure transitions from a two-dimensional planar configuration to a three-dimensional spatial arrangement by adding inclined portions that extend upward at angles of 20° to 80°. This dimensional enhancement allows flames to burn in multiple directions (horizontally and upwardly), creating depth and graduation in the flame shape.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Shape

If a burner with three-dimensional geometric shape is used, then a realistic flame effect simulating firewood burning is achieved, but the device complexity increases

Engineering Contradiction:
Improveflame shapeVSAvoidburner structure
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The combustion chamber main body, horizontal portions, and inclined portions are merged into an integrated burner assembly with interconnected hollow structures. The gas distribution system merges multiple gas intake ports and passages into a unified network that supplies fuel gas to all flame holes simultaneously, simplifying the overall device despite the complex three-dimensional flame shape.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The burner structure serves multiple functions: it distributes fuel gas through its hollow internal passages, supports simulated solid fuels on its surfaces, provides structural framework for the combustion system, and shapes the three-dimensional flame pattern. This multi-functionality reduces the need for separate components, offsetting the complexity increase.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Shape

If simulated solid fuels are added to the burner, then the visual realism of firewood burning is enhanced, but the device complexity and installation complexity increase

Engineering Contradiction:
Improveflame shapeVSAvoidinstallation process
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

Simulated solid fuels in the form of artificial logs or wood pieces are placed on the inclined portions of the burner to visually replicate real firewood. These simulated fuels are arranged to mimic natural wood stacking patterns, enhancing the realistic appearance of the fireplace while maintaining the underlying gasification combustion process.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The simulated solid fuels are designed as simple, lightweight decorative elements that can be easily replaced or rearranged. Their primary function is visual rather than structural, allowing users to change the arrangement for aesthetic purposes without affecting the core combustion system operation.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

AI summary

The present invention discloses a fireplace for gasifying and burning fuel. The fireplace includes a housing, a burner, a gasification device, a liquid supply device, a fuel tank, and a controller. The burner is composed of a gas intake port, several horizontal portions, and several inclined portions. One end of each inclined portion located at a lower position is connected and fixed to one end of a horizontal portion, and the other ends of all the horizontal portions are connected to each other either directly or by means of a combustion chamber main body. The horizontal portions, the inclined portions, and the combustion chamber main body each have an internally hollow structure and are in communication with each other. The inclined portions are inclined upwardly with respect to the horizontal portions, and the inclined portions and the horizontal portions are combined into a three-dimensional geometric space shape. The gas intake port is provided below the burner and communicates with the interior of the burner. The horizontal portions are provided with first flame holes, the inclined portions are provided with second flame holes, and the combustion chamber main body is provided with third flame holes. When the burner is ignited, flames are burning in each of the combustion chamber main body, the horizontal portions, and the inclined portions, thereby forming a flame effect in a three-dimensional (3D) form.
