Solution Overview

Problem

Conventional cookers with top burners struggle to effectively heat containers of varying shapes, and there is a need for a cost-effective and simple manufacturing solution for such burners.

Innovation Solution

The top burner design includes an outer and inner burner with differently arranged flame holes, allowing for efficient combustion of mixed gas, where the inner burner is positioned within the outer burner, and the distance between flame holes can vary, enabling flexible heating of containers with different shapes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional top burner with uniform flame hole arrangement is used, then the manufacturing is simple, but it cannot effectively heat containers of varying shapes

Engineering Contradiction:

Improveability to heat containers of varying shapesVSAvoidburner structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The burner is divided into multiple independent burners (e.g., circular burner, rectangular burner, oval burner), each with flame holes arranged in a specific pattern corresponding to different container shapes. This segmentation allows each burner to be optimized for a particular shape while maintaining manufacturing simplicity for each individual burner.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The top burner assembly incorporates multiple burners with different flame hole arrangements (circular, rectangular, oval patterns) to create a multi-functional system that can effectively heat various container shapes including circular, rectangular, and oval containers, making a single burner assembly universal for different cooking needs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple burners with different flame hole arrangements are provided, then containers of different shapes can be heated effectively, but the manufacturing cost and complexity increase

Engineering Contradiction:

Improveaccommodation of different container shapesVSAvoidmanufacturing simplicity and cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Multiple burners with different flame hole arrangements are integrated into a single top burner assembly, where burners are positioned side-by-side or in a nested configuration on the same burner body. This nesting approach allows multiple functional burners to be manufactured as one integrated unit, reducing overall manufacturing complexity and cost compared to producing separate burner assemblies.

Inventive Principle:

Principle #7Nested doll (Nesting)

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

This design allows for effective heating of variously shaped containers while simplifying the manufacturing process and reducing costs, as it can accommodate containers with both circular and rectangular bottoms using a single top burner.

AI summary

A top burner and a cooker having the top burner are provided. The top burner includes a first burner provided with a plurality of flame holes that form flame by combusting mixed gas and a second burner provided with a plurality of flame holes that form flame separated from the flame formed by the flame holes of the first burner by combusting the mixed gas. An arrangement of the flame holes of the first burner is realized in a different shape from an arrangement of the flame holes of the second burner.
