Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flame simulation technologies fail to replicate a realistic flickering effect, often appearing artificial and causing annoyance due to the creation of smoke, heat, and residue associated with traditional flame-based light sources.
Innovation Solution
A flame simulation method and apparatus that utilize a computing device to control the brightness of lighting elements through pseudo-random event generators, simulating wind agility and flame calmness, thereby creating a more realistic flickering effect by adjusting the brightness levels of multiple independently controlled light sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional flame-based light sources are used, then a warm ambient lighting effect is achieved, but fire risk and harmful factors (smoke, heat, residue) are created
Solution Approach 1:
The patent creates a flame simulation apparatus that copies the visual appearance of a flame using LED lighting elements arranged in a circular pattern. The controller simulates flame characteristics by randomly adjusting the brightness of individual LEDs to create a flickering effect, providing the warm ambient lighting of a real flame without the harmful factors.
Solution Approach 2:
The patent replaces the mechanical/chemical combustion process of traditional flames with an electrical system using LED lighting elements controlled by a microcontroller. This substitution eliminates fire risk, smoke, heat generation, and residue while maintaining the visual characteristics of a flame through electronic control of light emission.
2Device complexity
If simple random-loop-based algorithms are used for flame simulation, then implementation is simple, but the flickering effect appears artificial and causes annoyance
Solution Approach 1:
The patent divides the flame simulation into multiple independent LED lighting elements arranged in a circular pattern. Each LED can be controlled independently by the controller, allowing for more sophisticated and realistic flickering patterns. The segmentation of the flame into multiple controllable points enables complex randomization algorithms that produce natural-looking variations in brightness and timing.
Solution Approach 2:
The patent implements dynamic control of LED brightness levels through a randomized algorithm that continuously adjusts the intensity of each LED element. The controller randomly selects which LEDs to activate and at what brightness level, creating ever-changing flickering patterns that mimic the natural randomness of a real flame. This dynamic adjustment prevents the artificial, repetitive appearance of simple loop-based algorithms.

AI summary
A method for simulating a candle flame with at least one computing device. The method may include controlling at least one lighting element according to at least a current wind value and a current flame value. The method may include controlling the current wind value and the current flame value by iteratively determining whether a first event occurred. When the first event is determined to have occurred, the method may include setting the current wind value to a random wind value and then changing the current wind value toward a baseline wind value. When the first event is determined to have not occurred, the method may include changing the current wind value toward the baseline wind value, determining whether a second event occurred. When the second event is determined to have occurred, the method may include setting the current flame value to a random flame value.
