Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional candles are used to simulate flame effect, then realistic flickering flame effect is achieved, but environmental pollution and fire hazards occur
Solution Approach 1:
The patent replaces the mechanical combustion system of traditional candles with an electromagnetic system consisting of a coil and magnet. The coil generates a magnetic field that interacts with the magnet to produce irregular motion of the light-transmitting member, simulating flame flickering without combustion. This substitution eliminates fire hazards and pollution while maintaining the visual effect.
Solution Approach 2:
The patent creates a visual copy of candle flame effect using LED light source combined with a light-transmitting member that swings irregularly. The LED board emits light that passes through the moving light-transmitting member, producing a flickering effect that copies the appearance of real flame without the harmful properties of actual combustion.
2Illumination intensity
If swinging light-transmitting member is used to simulate flickering flame, then realistic flame effect is achieved, but service life is reduced due to mechanical failure
Solution Approach 1:
The patent eliminates complex transmission mechanisms (gears, linkages, bearings) by using a direct electromagnetic interaction system. The coil and magnet are positioned to interact directly, causing the light-transmitting member to swing without requiring intermediate mechanical components. This reduces wear and failure points, significantly improving reliability and service life.
Solution Approach 2:
The patent employs dynamic positioning of the magnet relative to the coil to generate irregular, natural-looking flame motion. The magnet is positioned off-center to create asymmetric swinging motion that mimics real flame behavior. The system transitions from static to dynamic operation, allowing the light-transmitting member to move freely within a defined range without mechanical constraints.
3Productivity
If LED-based candle lamp with lenses is used to enhance lighting efficiency, then lighting efficiency is improved, but flame simulation realism is reduced
Solution Approach 1:
The patent replaces static lens-based flame simulation with a dynamic system where the light-transmitting member swings irregularly in response to magnetic field interaction. This dynamic motion creates more realistic flickering patterns compared to fixed optical elements. The LED board provides efficient lighting while the moving light-transmitting member adds natural flame characteristics.
Solution Approach 2:
The patent uses a light-transmitting member with specific local properties - it is positioned to receive light from the LED board and transmit it in a controlled manner. The member's material and shape are optimized to create appropriate light diffusion and flickering effects locally, while the overall system maintains high lighting efficiency through the LED source.

Function Achieved in This Case
The solution provides a long-lasting, safe, and realistic candle flame simulation without the risks of naked flames, improving lighting efficiency and creating a romantic atmosphere while reducing energy consumption and mechanical failures.
Implementation Method 1
The coil is connected to a coil power supply branch of the power cord so as to form an electromagnetic field that changes over time and interacts with the magnet
Implementation Method 2
The lampshade and the fixing member are assembled together to form a unity that is suspended to the support structure of the immovable part of the lighting device by means of an elastic member

AI summary
The present disclosure relates to a lighting device simulating visual effect of candle flame includes an immovable assembly and a movable assembly. The immovable assembly has a stationary supporting structure for holding a light source in position. The movable assembly has a light-effect component for simulating visual effect of natural flame at a candle wick. The movable assembly further includes at least a part of a driving component accommodated in the supporting structure. The part of the driving component and the light-effect component of the movable assembly are such connected to each other that when the part of the driving component moves positively and/or is driven to move passively, at least a part of the light-effect component performs swing movement. The lighting device thus can simulate naturally flickering or dancing flame of a burning candle, thereby creating lighting effect and atmosphere as those provided by a real candle.
