Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing lighting technologies are used, then the device structure is simple, but the accuracy of simulating flame chemistry and turbulence is insufficient
Solution Approach 1:
The lighting device is divided into multiple discrete light emission points (DLEPs) that can be independently controlled. Each DLEP represents a specific region of the simulated flame, allowing different intensity values to be applied to different segments to create realistic flame chemistry variations and turbulence patterns.
Solution Approach 2:
The system employs dynamic intensity adjustment where the controller continuously modifies the intensity values of individual DLEPs based on simulated flame chemistry parameters and turbulence characteristics. This dynamic control enables the lighting device to accurately replicate the ever-changing nature of real flames.
2Adaptability or versatility
If a single light source is used, then the device complexity is low, but the ability to simulate flame variations over time is limited
Solution Approach 1:
Instead of using a single light source, the invention employs multiple discrete light emission points arranged to represent different zones of a flame. Each DLEP can be independently controlled with different intensity values, enabling the system to simulate various flame characteristics including chemistry variations and turbulence patterns that a single source cannot achieve.
Solution Approach 2:
Different regions of the flame are illuminated with different intensity characteristics. The controller assigns specific intensity values to each DLEP based on the local flame chemistry and turbulence conditions, creating a spatially varying light distribution that accurately represents the non-uniform nature of real flames.
3Reliability
If static light intensity is used, then the control system is simple, but the realism of flame simulation is reduced
Solution Approach 1:
The control system dynamically adjusts the intensity of each DLEP over time based on simulated flame chemistry parameters and turbulence characteristics. This temporal variation in light intensity creates a realistic flame simulation that captures the natural fluctuations and movements of real flames, rather than maintaining a static appearance.
Solution Approach 2:
The system incorporates feedback mechanisms where the controller monitors the simulated flame parameters and adjusts the DLEP intensities accordingly. This feedback loop ensures that the lighting device accurately responds to changes in flame chemistry and turbulence, maintaining high realism in the simulation.

AI summary
A lighting device includes a housing having a cavity and a translucent area, a plurality of discrete light emission points (DLEPs) positioned in the cavity for emitting light through the translucent area, a power source, and a controller causing the DLEPs to simulate a burning wax candle. The housing is configured to imitate a wax candle. The controller actuates a first of the DLEPs according to sequential first intensity values, and actuates a second of the DLEPs according to sequential second intensity values. The sequential first intensity values are determined by sequentially combining first change values to an initial first intensity value, and the sequential second intensity values are determined by sequentially combining second change values to an initial second intensity value. Sequential increases/decreases in the first intensity values simulate increases/decreases in optimal flame chemistry, and sequential increases/decreases in absolute value of the first change values simulates increases/decreases in turbulence.
