Solution Overview

Problem

Existing shielding devices fail to effectively prevent flame extinguishment by wind and do not adequately protect users from flames generated by burner assemblies.

Innovation Solution

A complementary-shaped tube is designed to fit around the burner assembly's well, with a heat-resistant structure that shields the flame from wind and positions the upper end near the grate's upper limit, ensuring the flame is protected and heat is evenly distributed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a shielding device is added to protect the flame from wind, then flame stability is improved, but device complexity increases

Engineering Contradiction:

Improveflame stabilityVSAvoidshielding device structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The shielding device is divided into a modular tube structure that can be assembled in sections, allowing the flame shield to protect against wind while maintaining manageable complexity through segmented design

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A tube structure is introduced as an intermediary element between the flame and the wind, physically blocking harmful wind forces from directly contacting the flame while preserving heat transfer efficiency

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the tube is positioned close to the grate to shield the flame, then flame protection is improved, but heat distribution to larger pots and pans may be compromised

Engineering Contradiction:

Improveflame protectionVSAvoidcompatibility with larger pots and pans

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The tube structure extends vertically above the grate rather than horizontally across it, protecting the flame from lateral wind forces while maintaining vertical heat rise that can accommodate various pot and pan sizes

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The shielding tube is designed with dimensions and positioning that allow it to protect the flame effectively while simultaneously being compatible with a range of cookware sizes, achieving multi-functionality for both flame protection and universal pot compatibility

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A burner assembly shielding device for preventing blowout of a flame generated by the burner assembly includes a tube that is sized and shaped complementarily to a perimeter of a well of a burner assembly. A lower end of the tube is configured to insert into the well so that an upper end of the tube is fixedly positioned proximate to an upper plane that is defined by an upper limit of a grate of the burner assembly. A wall of the tube is configured to shield a flame that is generated by the burner assembly from wind to prevent the flame from being extinguished.
