Solution Overview

Problem

Conventional decorative gas fireplaces struggle to replicate an authentic wood fire effect, as the heating of ceramic elements diminishes the visible flame height and visual appeal, and existing solutions are inefficient in managing heat and gas consumption.

Innovation Solution

A gas fireplace design incorporating a separate light source to create a glowing effect on fireplace elements, controlled independently of the burner, along with a light conductor to direct light and enhance the visual authenticity, and optional features like a spark simulator and smoke simulator to simulate a fire, while managing heat and gas usage effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If ceramic elements are heated to create a glowing effect, then the visual authenticity of the fireplace is improved, but the visible flame height is reduced and gas consumption increases

Engineering Contradiction:
Improveglowing effectVSAvoidflame height
Core Design Contradiction:
Illumination intensityVSLength of moving object

Solution Approach 1:

The patent divides the fireplace system into separate functional components: a burner element for producing flames and a lighting element for creating the glowing effect. This segmentation allows independent control of flame height and glowing intensity, resolving the contradiction by enabling both functions to operate optimally without interfering with each other.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The glowing effect function is extracted from the heating process. Instead of using the burner to heat ceramic elements for glow, a separate lighting element is introduced. This extraction eliminates the trade-off between flame height and glowing effect, as the lighting element provides glow without consuming gas or reducing flame size.

Inventive Principle:
Principle #2Taking out (Extraction)

2Illumination intensity

If ceramic elements are heated to create a glowing effect, then the visual authenticity of the fireplace is improved, but gas consumption increases

Engineering Contradiction:
Improveglowing effectVSAvoidgas consumption
Core Design Contradiction:
Illumination intensityVSUse of energy by moving object

Solution Approach 1:

The glowing effect function is extracted from the gas combustion process and assigned to a separate lighting element. This extraction eliminates the direct consumption of gas for creating glow, as the lighting element uses electrical energy instead, thereby resolving the contradiction between glowing effect and gas consumption.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the energy parameter from thermal (gas combustion) to electrical (lighting element). This parameter change allows the glowing effect to be achieved without increasing gas consumption, as the lighting element operates independently on electrical power.

Inventive Principle:
Principle #35Parameter changes

3Length of moving object

If more gas is supplied to increase flame height, then the visual effect is improved, but the heating of fireplace elements increases which reduces visible flame height

Engineering Contradiction:
Improveflame heightVSAvoidheating of fireplace elements
Core Design Contradiction:
Length of moving objectVSTemperature

Solution Approach 1:

The patent segments the functions of flame production and glowing effect into separate elements. The burner element focuses on producing visible flames without the need to heat ceramic elements for glow, while the lighting element handles the glowing effect. This segmentation resolves the contradiction by eliminating the competing thermal demands.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent replaces the thermal mechanism (heating ceramic elements to produce glow) with an optical/electrical mechanism (lighting element). This substitution eliminates the unwanted heating of fireplace elements while maintaining the desired glowing effect, allowing flame height to be increased without the counterproductive heating effect.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
