Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic candle lamps have low simulation degree, inadequate representation of a blackened wick, wax oil dripping, and poor blue flame simulation, and suffer from short battery life due to insufficient driving voltage.
Innovation Solution
A highly simulated electronic candle design featuring a simulated casing with a wax oil layer, a wick conduit with a burnt layer, a booster circuit with a chip, and a flame front with a light blue luminous body, along with a battery holder and circuit board configuration that maintains voltage above 2.2V, enhancing simulation and battery efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a wire is used to simulate the wick without considering carbonization blackening, then the structure is simple, but the simulation degree is low and distortion is large
Solution Approach 1:
The wick conduit is divided into two distinct sections: an upper portion without burnt layer and a lower portion with simulated burnt layer. This local differentiation allows the wick to accurately represent the carbonized state at the base while maintaining the functional structure at the top, resolving the contradiction between structural simplicity and simulation accuracy.
2Device complexity
If a groove is formed in the candle lamp housing to consider wax oil accumulation, then the structure is improved, but the dripping effect of wax oil is not simulated
Solution Approach 1:
A simulated wax oil layer made of transparent or translucent material is introduced as an intermediary element between the groove and the flame. This layer not only fills the groove but also reflects light to simulate the appearance of accumulated wax oil and creates the visual effect of dripping, thereby enhancing the simulation degree without significantly complicating the housing structure.
3Device complexity
If flame sheets or single mono-color LED lamps are used to simulate flame combustion, then the device is simple, but the simulation effect is poor and blue flame core is not achieved
Solution Approach 1:
The flame simulation is segmented into multiple functional components: a blue flame core luminous body for the high-temperature center, an orange flame sheet for the outer combustion layer, and a simulated wax oil layer for reflection. This segmentation allows each component to fulfill its specific function, achieving a realistic multi-layered flame effect with accurate color differentiation.
4Device complexity
If two 2XAA batteries in series structure are used with 3V voltage, then the device is simple, but the service life is short and battery capacity is wasted when voltage drops to 2V
Solution Approach 1:
A booster circuit is introduced to dynamically change the voltage parameter, boosting it from 1.5V to 3V as needed. This allows the use of two single-AA batteries that can be replaced individually when depleted, extending the overall service life and preventing waste of battery capacity in the remaining cell.
5Reliability
If LEDs require more than 2V-2.4V driving voltage and main control chip needs more than 2.2V working voltage, then the electronic circuit works normally, but the battery cannot work when voltage depletes to about 2V
Solution Approach 1:
The booster circuit performs preliminary action by boosting the battery voltage to the required level before it reaches the critical 2V threshold. This ensures that the LEDs and control chip continuously receive adequate voltage throughout the battery's discharge cycle, maintaining reliable operation and extending the usable period of the battery.

AI summary
A highly simulated electronic candle includes a simulated casing, a battery holder, a circuit board, a wick wire, and a flame front. A top of the simulated casing is depressed downwards to form a first groove, and an epoxy resin is injected into the first groove to form a simulated wax oil layer. The battery holder is arranged at an inner bottom end of the simulated casing. The circuit board is electrically connected to the battery holder. The wick wire is electrically connected to the circuit board and extending upwards through the simulated wax oil layer. The flame front is fixedly connected to a top end of the wick wire. The highly simulated electronic candle has a high simulation degree, simulates a wax oil dripping or a flame reflection of a real candle after burnt.
