LED Candle Light and Fragrance Atomizer Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices fail to provide a single solution that mimics the aesthetic of scented candles by emitting both light and fragrance without the risks associated with open flames, and they either lack the visual appeal of candles or the olfactory experience.
Innovation Solution
A device incorporating a light-emitting diode (LED) and a microprocessor that generates a pulse-width modulated waveform, coupled with a piezoelectric actuator and a feedback circuit, to create a flickering light effect, while also using an atomizer assembly to emit fragrance, mimicking the appearance and scent of a candle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an open flame candle is used to provide both light and fragrance, then the visual and olfactory experience is authentic, but safety risks increase due to fire hazards and wax dripping
Solution Approach 1:
The patent combines an LED light source with an atomizer fragrance dispensing system into a single integrated device. The LED provides flickering candle-like light while the atomizer simultaneously dispenses fragrance, merging two separate functions (lighting and fragrance delivery) into one unified system that eliminates fire hazards while preserving the candle experience.
Solution Approach 2:
The patent replaces the mechanical/chemical combustion process of traditional candles with an electronic LED lighting system. The LED, controlled by a microprocessor to create flickering effects, substitutes the flame's visual function without the thermal hazards, while the atomizer uses ultrasonic vibration rather than combustion to deliver fragrance.
2Adaptability or versatility
If electronic lighting devices are used to mimic candle appearance, then safety is improved by eliminating open flames, but the scented candle experience is lost due to inability to emit fragrance
Solution Approach 1:
The patent integrates an LED lighting system with an atomizer fragrance dispensing system into a single coordinated device. Both components are controlled by a microprocessor that synchronizes the flickering light pattern with the fragrance emission cycles, creating a unified candle-like experience that combines visual and olfactory elements.
Solution Approach 2:
The patent creates a multi-functional device that simultaneously performs lighting (LED with flicker control) and fragrance dispensing (atomizer system) functions. This universal device replaces the need for separate candle and fragrance dispenser, providing both visual and olfactory candle experiences through a single integrated system.
3Quantity of substance
If fragrance is dispensed continuously, then the ambient area is adequately scented, but energy consumption and material loss increase
Solution Approach 1:
The patent implements periodic fragrance dispensing through the atomizer system, which operates in cycles synchronized with the flickering light pattern. The microprocessor controls the atomizer to emit fragrance at specific intervals rather than continuously, reducing energy consumption and fragrance material usage while maintaining adequate ambient scent levels through strategically timed emissions.
