Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooking appliances with single or double burners face inefficiencies in flame distribution and ignition stability, particularly when using different types of gases, leading to inconsistent heating and potential safety hazards.
Innovation Solution
The design incorporates a double burner structure with an outer and inner burner head, featuring flame spread spaces and strategically positioned ignition holes to ensure stable ignition and efficient flame distribution, regardless of gas type, using a burner body that mixes gas and air for efficient heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single burner or conventional double burner is used, then the structure is simple, but flame distribution is inefficient and ignition stability is poor
Solution Approach 1:
The burner head is divided into an inner burner head and an outer burner head with separate flame holes. The inner burner head has inner flame holes for central flame generation, while the outer burner head has outer flame holes for peripheral flame generation. This segmentation allows independent control and optimization of flame patterns in different zones, improving ignition stability without requiring an overly complex overall structure.
Solution Approach 2:
The inner burner head is nested within the outer burner head, creating a concentric double burner structure. The inner burner head is positioned centrally within the outer burner head, allowing both burners to share the same mounting space while providing distinct flame zones. This nesting approach increases functional complexity without proportionally increasing the external footprint or structural complexity.
2Productivity
If flame spread spaces are added to improve flame distribution, then heating efficiency increases, but device complexity increases
Solution Approach 1:
The flame spread spaces extend the flame generation in the vertical dimension by creating upward-flow paths from the inner flame holes through the central passage to the outer flame holes. This vertical flame spread mechanism increases the effective heating surface area and improves heating efficiency without requiring a larger horizontal footprint, thus limiting the increase in overall device complexity.
Solution Approach 2:
Different regions of the burner head are given different functional qualities: the inner burner head is optimized for central flame generation with specific inner flame hole patterns, while the outer burner head is optimized for peripheral flame generation with outer flame holes positioned at the periphery. This local differentiation improves flame distribution efficiency without requiring complete redesign of the entire burner structure.

AI summary
Provided is a burner. The burner includes a burner body receiving a gas and air, a burner head seated on the burner body, the burner head including an inner burner head and an outer burner head, and a burner cap seated on the burner body to cover the burner head. An outer flame hole through which a mixture gas is discharged and a flame spread space for spreading flame into the inner burner head are defined on the outer burner head, and an inner flame hole through which the mixture gas is discharged and an ignition hole defined under the inner flame hole are defined on the inner burner head.
