Retractable Electronic Candle Flame With Dust-Blocking Lid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional candles have a short lifespan and pose a fire risk, while electronic candles accumulate dust and are difficult to clean due to their special shape.
Innovation Solution
An electronic candle design featuring a movable lid and light-emitting component that vertically protrudes and retracts, along with a transfer mechanism and controller to prevent dust entry and facilitate easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light emitting component with a special flame shape is used to create aesthetic appeal, then the decorative quality is improved, but the ease of cleaning deteriorates due to dust accumulation in complex geometries
Solution Approach 1:
The light emitting component is made movable rather than fixed, allowing it to retract into the housing for cleaning access. This dynamic design enables the component to change position between operational mode (protruding) and cleaning mode (retracted), resolving the contradiction between aesthetic quality and ease of cleaning.
2Illumination intensity
If the light emitting component protrudes from the housing to simulate a real flame, then the aesthetic quality is improved, but dust accumulation increases on the exposed surface
Solution Approach 1:
The light emitting component dynamically changes position between protruding (for aesthetic quality) and retracted (to prevent dust accumulation). This movement allows the system to optimize for different operational states, reducing dust exposure while maintaining flame simulation capability.
Solution Approach 2:
The light emitting component is extracted from the housing during cleaning operations, separating it from the housing structure. This extraction allows for easy removal and cleaning of the component without disassembling the entire housing, addressing the dust accumulation issue.
3Device complexity
If a fixed light emitting component is used to simplify the structure, then the device complexity is reduced, but the ability to prevent dust entry deteriorates
Solution Approach 1:
A movable lid is introduced that dynamically opens and closes based on the operational state. When the light emitting component is retracted, the lid closes to prevent dust entry. This simple dynamic mechanism effectively prevents dust without requiring complex sealing systems.

AI summary
Methods, systems and devices associated with an electronic candle are described. In one example, an electronic candle comprises a housing having a through-hole at its top and a component shell. The component shell encloses a transfer mechanism including a driver motor and one or more gears positioned inside the component shell, a light emitting component coupled to the transfer mechanism such that the transfer mechanism causes the light emitting component to move vertically up or down to protrude from the housing or to retract into the housing, a lid positioned inside the component shell and movable to remain in at least one of an open configuration or a closed configuration, and a controller configured to turn on or off the light emitting component. The candle also includes a controller configured to turn on or off the light emitting component.
