Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flameless candles lack the ability to simulate a natural flame flicker and provide a scented experience similar to traditional candles, while also having inconvenient control mechanisms.
Innovation Solution
An electronic flameless candle design that incorporates a LED light source with a circuit board to create a realistic flame flicker, includes a scent diffusing component, and features a control switch integrated into the candle body to allow easy operation, mimicking the appearance and functionality of traditional candles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flameless candles use incandescent lamps or LEDs as light source, then safety is improved (no open flame), but visual realism deteriorates (cannot simulate natural flame flicker)
Solution Approach 1:
The patent applies dynamics by using a flicker simulation circuit that randomly varies the light output intensity and timing to mimic the natural, unpredictable motion of a real flame. The LED is controlled through a microcontroller that generates random flicker patterns, transforming a static light source into a dynamic one that visually resembles a living flame while maintaining the safety of flameless operation.
Solution Approach 2:
The patent changes the operational parameters of the LED by varying its brightness, flicker frequency, and color temperature through electronic control. The flicker simulation circuit adjusts these parameters dynamically to replicate the characteristics of a real candle flame, resolving the contradiction between safety and visual realism.
2Ease of operation
If flameless candles use traditional switch mechanisms on the base, then ease of operation deteriorates (requires removing candle from resting place), but device complexity is reduced
Solution Approach 1:
The patent replaces the mechanical switch system with a wireless control system using RFID technology. The user can operate the candle by bringing an RFID-enabled device near the candle base, eliminating the need for physical contact or removal of the candle. This substitution of mechanical control with electromagnetic field-based control dramatically improves ease of operation while adding minimal complexity through the use of standardized RFID components.
3Device complexity
If flameless candles lack scent emission capability, then simplicity is maintained, but sensory experience deteriorates (cannot provide scented feature like traditional candles)
Solution Approach 1:
The patent integrates multiple functions into the flameless candle system, including light emission, flicker simulation, wireless control, and scent diffusion. The scent module uses a heating element to vaporize scented wax or essential oils, adding olfactory functionality to the visual and control features. This multi-functionality approach enhances the overall sensory experience while maintaining relatively simple individual components that can be added modularly.
