Solution Overview

Problem

Existing gas burners have a heightened top burner part due to the need for a space to install the nozzle and allow gas to flow upwards, increasing the overall height and complicating the cleaning process, which exposes the upper plate to external elements and makes it difficult to maintain cleanliness.

Innovation Solution

The design incorporates a nozzle installation part that protrudes through a hole in the upper plate, allowing the nozzle to be positioned above the plate, reducing the internal height of the burner body and using supporting parts with reduced horizontal cross-sectional areas for easier cleaning, while preventing foreign substances from entering the burner assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the nozzle is installed inside the burner body below the upper plate, then the gas can flow upward through the burner body, but the longitudinal height of the burner body must be increased to accommodate the nozzle installation space and gas flow path

Engineering Contradiction:
Improvenozzle installationVSAvoidburner body height
Core Design Contradiction:
Ease of manufactureVSLength of moving object

Solution Approach 1:

The nozzle is inverted from its conventional position inside the burner body to protrude upward through the upper plate. This inversion eliminates the need for internal nozzle installation space and upward gas flow path within the burner body, thereby reducing the longitudinal height of the burner body while maintaining functional integrity

Inventive Principle:
Principle #13The other way round (Inversion)

2Ease of operation

If the burner head is separated from the burner body for cleaning, then the burner head and cap can be cleaned, but the hole in the upper plate is exposed to the outside making it difficult to clean the upper plate and allowing water or foreign substances to enter

Engineering Contradiction:
Improvecleaning accessibilityVSAvoidforeign substance contamination
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The nozzle serves as an intermediary element that protrudes through the upper plate, creating a sealed interface between the burner interior and exterior. This intermediary structure allows the upper plate to be cleaned without exposing internal components to foreign substances, as the nozzle itself can be removed and cleaned separately while maintaining the sealing function

Inventive Principle:
Principle #24Intermediary (Mediator)

3Length of moving object

If the nozzle installation part protrudes through the upper plate, then the internal height of the burner body is reduced, but the supporting parts must have reduced horizontal cross-sectional areas to facilitate cleaning

Engineering Contradiction:
Improveburner body heightVSAvoidsupporting part cross-sectional area
Core Design Contradiction:
Length of moving objectVSArea of stationary object

Solution Approach 1:

The supporting parts are designed with non-uniform cross-sectional areas, featuring reduced horizontal dimensions in regions that require cleaning access. This local quality modification allows the supporting parts to maintain structural function while facilitating easier cleaning, as the reduced cross-sectional areas create smoother surfaces and fewer crevices where debris can accumulate

Inventive Principle:
Principle #3Local quality
