Innovation Solution
An electronic scented candle design featuring a flame piece, shell with an installation chamber, fragrance container with a liquid suction channel, scent chamber, and heating device, which rapidly generates and dissipates scented material through thermal energy and air flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional candles are used to provide ambiance and scent, then the atmosphere is enhanced, but the fire hazard increases and lifetime is reduced
Solution Approach 1:
The patent replaces the mechanical/chemical combustion system of traditional candles with an electronic heating system. A heating element heats a fragrance material in a scent chamber, causing it to vaporize and disperse through air flow channels, eliminating the open flame while maintaining the ambiance and scent functions
Solution Approach 2:
The patent changes the operating parameters from high-temperature combustion (candle flame) to controlled low-temperature heating (heating element). This parameter change allows the fragrance material to vaporize and disperse without requiring an open flame, thus eliminating fire hazard while maintaining functionality
2Device complexity
If existing electronic scented candles use a fan to force scent release, then the structure is simplified, but the scent production quality deteriorates
Solution Approach 1:
The patent uses natural convection currents created by the heating element to drive air flow through the scent chamber and out through outlets. The heated air rises and creates a natural flow pattern that carries the fragrance vapor, eliminating the need for mechanical fans while improving scent dispersion quality
Solution Approach 2:
The patent utilizes the phase transition of the fragrance material from liquid to vapor through controlled heating. The heating element vaporizes the fragrance material in the scent chamber, and the phase-changed vapor is then carried by natural convection currents to the outlets, improving scent production without requiring complex mechanical systems
3Device complexity
If electronic scented candles use traditional heating methods, then the device is simpler, but the scent generation speed is reduced
Solution Approach 1:
The patent nests the fragrance material container inside the scent chamber, which is itself inside the main body of the electronic candle. This nested arrangement allows the heating element to directly heat the fragrance material through the chamber walls, rapidly generating scent without complex external delivery systems
Solution Approach 2:
The scent chamber acts as an intermediary between the heating element and the external environment. The heating element heats the fragrance material within the scent chamber, causing rapid vaporization, and the chamber's design with integrated air flow channels enables quick dispersion of the generated scent
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The electronic scented candle provides a convenient and efficient means of scent dispersion, offering rapid scent generation and dissipation, improved safety compared to traditional candles, and enhanced user experience.
Implementation Method 1
a liquid suction channel positioned within the fragrance container, where a first end of the liquid suction channel protrudes from the fragrance container into the scent chamber and a second end of the liquid suction channel is positioned within the fragrance container to draw a fragrance material from the fragrance container to the scent chamber
Implementation Method 2
a heating device in communication with the scent chamber to provide thermal energy to the fragrance material drawn into the scent chamber and to the external air drawn into the scent chamber through the air inlet. The heating device is configured to impart the thermal energy to contents of the scent chamber and to volatize the contents of the scent chamber
Implementation Method 3
an air inlet in communication with the scent chamber to direct air from the external environment to the scent chamber

AI summary
An electronic scented candle is described that includes a movable flame-shaped component, a shell including an installation chamber, a fragrance container that is removably positioned inside the installation chamber and a scent chamber. An electric fan is positioned within the shell to drive the air into the scent chamber and a scent outlet coupled to the scent chamber to allow the fragrance material to leave the scent chamber and to reach an external environment of the electronic scented candle. The electronic candle also includes a receptacle for connecting a power cord on a bottom surface of the electronic candle. The bottom surface includes a plurality of protruding stands that provide a space to allow the power cord to be connected to the receptacle and be routed below the bottom surface.
