Three-dimensional flame generation for electric fireplace
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electric fireplaces lack a realistic and simple-to-implement three-dimensional simulated flame generator, resulting in an unconvincing aesthetic and complex design.
Innovation Solution
A flame generator that directs light in multiple directions using a reflective element and a generator light source, creating a three-dimensional simulated flame by positioning light through angular ranges defined by the assembly openings in the log assembly, allowing for a modular and aesthetically pleasing design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional flame generator design is used, then the simulated flame can be generated, but the design becomes overly complex and the flame does not look realistic
Solution Approach 1:
The flame generator is segmented into three independent light sources positioned at different locations (front, side, and rear of the firebox), each responsible for illuminating specific portions of the simulated flame. This segmentation allows each light source to be simple in design while collectively creating a realistic three-dimensional flame effect, resolving the contradiction between realism and complexity.
Solution Approach 2:
The patent transitions from two-dimensional flame simulation to three-dimensional flame simulation by adding depth through the rear light source and using transparent or translucent log assemblies that allow light to pass through and create volumetric flame effects. This dimensional enhancement improves realism without requiring complex mechanical mechanisms.
2Reliability
If multiple light sources are used to create three-dimensional flame, then realism is improved, but device complexity increases
Solution Approach 1:
Multiple light sources are merged into a coordinated system where each light source (front, side, and rear) works together to illuminate different aspects of the simulated flame. The controller merges their operation to create a unified three-dimensional flame effect, achieving enhanced realism while keeping individual component designs simple and manageable.
Solution Approach 2:
Each light source serves multiple functions: the front light source illuminates the front surface and can pass through transparent logs to create internal flame effects; the side light source provides lateral illumination; the rear light source creates depth and background flame effects. This multi-functionality reduces the need for specialized complex components for each function.
3Reliability
If transparent or translucent log assembly is used, then three-dimensional flame effect is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent changes the optical parameter of the log assembly from opaque to transparent or translucent, which fundamentally alters how light interacts with the logs. This parameter change enables the three-dimensional flame effect by allowing light to pass through and illuminate the simulated flame from multiple directions, while the modular design maintains manufacturing feasibility through standard material processes.

AI summary
An electric fireplace (10) includes a log assembly (319) and a flame generator (324). The flame generator (324) directs light away from the log assembly (319) in both a first direction (318A) and a second direction (318B) that is different from the first direction (318A) to generate a three-dimensional simulated flame (318).
