Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional methods are used to simulate a single candle flame, then the simulation can be created, but it fails to convincingly replicate the complex kinetic interactions and light movements of a real flame, especially at short viewing distances
Solution Approach 1:
The patent uses a physical flame silhouette element that is illuminated by a light source to create a visual copy of a real flame. The silhouette element is moved chaotically to replicate the natural, unpredictable motion of a real candle flame, providing a convincing simulation at short viewing distances without needing to model complex kinetic interactions computationally.
Solution Approach 2:
The patent employs a drive mechanism that generates chaotic motion of the flame silhouette element through electromagnetic interaction with ferromagnetic materials. This mechanical movement replicates the flickering and dancing motion of a real flame, creating visual realism without directly simulating the complex fluid dynamics and combustion processes.
2Measurement precision
If combustion-based candles are used, then a realistic flame effect is achieved, but safety issues arise due to the presence of flame and heat, and maintenance requirements increase
Solution Approach 1:
The patent replaces the combustion-based mechanical system with an electromagnetic system. Instead of using actual burning fuel, the invention uses a light source to illuminate a flame silhouette element that is moved by electromagnetic forces acting on ferromagnetic materials. This substitution eliminates fire hazards and heat generation while maintaining the visual appearance of a real flame.
Solution Approach 2:
The invention creates a visual copy of a combustion flame using light and shadow rather than actual combustion. The illuminated silhouette element replicates the appearance, color, and motion characteristics of a real candle flame without the dangerous byproducts of combustion, providing safety while maintaining realism.
3Illumination intensity
If conventional flame simulation devices are used, then flame display can be achieved, but they require substantial energy inputs and frequent battery replacement, driving up purchase and operating costs
Solution Approach 1:
The patent replaces energy-intensive mechanical or electronic display systems with a more efficient light-based system. The flame silhouette element is illuminated by a light source and moved by electromagnetic forces, which consume less energy than conventional LED arrays or other electronic flame simulation devices. This reduces both operating costs and maintenance requirements.

AI summary
An electric candle device that resembles a real was candle includes an outer shell with an uneven edge around the top of the outer shell. The device includes one or more light emitting elements positioned within a cavity inside the outer shell and that emit beams at a non-zero angle with respect to a longitudinal axis of the electric lighting device to provide illumination from within the cavity in an upward direction and reaching above the top surface after passing through the opening. An optical element is positioned to receive light from the one or more light emitting elements and to direct the received light toward the top surface. The optical element has a focal point to change one or both of a size and direction of the light received prior to projecting the light in the direction of the top surface.
