Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional electronic candles use simple switch power supply control, then the device complexity is low, but the realism and user experience are poor
Solution Approach 1:
The patent combines multiple functions (blowing control via pressure sensor, music playback via Bluetooth and memory card, flame simulation via LED and mechanical structure) into a single integrated electronic candle system. The control circuit board integrates multiple control functions, and the candle shell incorporates both the simulated flame body and loudspeaker, merging structure and function to achieve high realism without proportionally increasing complexity.
Solution Approach 2:
The electronic candle is designed with multiple functions: it can be controlled by blowing (pressure sensor), play music through Bluetooth connection, play music from memory card, and simulate flame movement. This multi-functionality allows a single device to replace multiple separate functions, improving realism and user experience while managing complexity through integration.
2Adaptability or versatility
If traditional electronic candles have fixed music playback, then the device complexity is low, but the adaptability and user experience are poor
Solution Approach 1:
The music playback system is designed with dual functionality: it can play music from a built-in memory card and can also receive music files wirelessly via Bluetooth connection. This allows the candle to adapt to different user needs and music sources without requiring complex wired connections or external devices, enhancing versatility while keeping the control system manageable through integrated Bluetooth and memory card interfaces.
Solution Approach 2:
The control circuit board acts as an intermediary that manages both the Bluetooth receiver and memory card slot, coordinating between different music sources and the loudspeaker. This intermediary component simplifies the overall system by centralizing control logic, allowing the candle to switch between different music playback modes without requiring separate control systems for each function.
3Reliability
If traditional electronic candles use simple LED lighting, then the device complexity is low, but the flame simulation realism is poor
Solution Approach 1:
The patent merges the LED light source with a mechanical simulated flame body structure. The LED is not simply placed inside a static housing but is integrated with a mechanical structure that can move and swing, combining optical emission with mechanical motion to create a more realistic flame effect. The candle shell itself is designed to accommodate both the LED and the simulated flame body in a unified structure.
Solution Approach 2:
The simulated flame body is designed with dynamic movement capability through the magnetic supporting mechanism. Instead of a static LED arrangement, the flame body can swing and move dynamically, controlled by the magnetic supporting rod and rotating ball mechanism. This dynamic behavior mimics the natural movement of real flames, significantly improving realism while using a relatively simple magnetic-mechanical system.
4Ease of operation
If traditional electronic candles lack blowing control, then the device complexity is low, but the interaction realism and user experience are poor
Solution Approach 1:
The pressure sensor acts as an intermediary that detects the physical action of blowing and converts it into an electrical signal that the control circuit board can process. This intermediary component bridges the gap between user interaction (blowing) and system response (flame extinction), enabling realistic interaction without requiring complex control logic. The flow guide tube further assists by directing airflow to the sensor efficiently.
Solution Approach 2:
The patent replaces traditional mechanical switching mechanisms with a pressure sensor-based detection system. Instead of using complex mechanical levers or buttons to control flame extinction, the system uses an electronic pressure sensor to detect airflow caused by blowing. This substitution of mechanical control with electronic sensing simplifies the interaction mechanism while enabling more nuanced and realistic control responses.
