Electronic Candle Flame-Head Touch Switch for Easier Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic candles face issues with power switches located on the bottom surface, requiring the candle to be picked up for operation, which is cumbersome, and often result in greasy surfaces due to waxy materials, impacting user experience and reliability.
Innovation Solution
An electronic candle design featuring a touch switch integrated into the simulated flame head, allowing operation by touching the flame head, with a control loop including the touch switch, luminous body, battery, and PCB board, and optionally a secondary switch at the base for dual-control modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power switch is arranged on the bottom surface of the base, then the device structure is simple, but the ease of operation deteriorates as the candle must be picked up to operate
Solution Approach 1:
The control function is moved from the bottom surface (horizontal plane) to the simulated flame head (vertical dimension), allowing operation without picking up the candle. The touch switch is integrated into the flame head structure, enabling users to control the candle by touching the top surface rather than the bottom.
2Shape
If the candle body is made of waxy material, then the aesthetic appearance is improved, but the object-generated harmful factors worsen due to greasy surface
Solution Approach 1:
The switch function is extracted from the waxy candle body surface and integrated into the simulated flame head structure. This allows the candle body to maintain its aesthetic waxy appearance while the control interface is separated into a non-greasy flame head component that can be touched without transferring wax residue.
3Ease of operation
If a touch-sensitive switch is used, then the ease of operation is improved, but the reliability deteriorates due to potential false triggering
Solution Approach 1:
The simulated flame head serves as an intermediary structure between the user's finger and the touch switch. By embedding the touch switch within the flame head housing rather than exposing it directly on the candle body, the system reduces false triggering from accidental contact while maintaining ease of intentional operation.
