Birthday candle with automatic lighting effect
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing birthday candles lack advanced features such as automatic lighting effects, limiting their ornamental and atmospheric impact.
Innovation Solution
A birthday candle with an automatic lighting effect is designed, featuring a paraffin wax candle body, a wick, a light sensor, a light source, and a control circuit board that synchronizes the light source and sounder with the burning wick.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional birthday candles are used with simple paraffin wax and wick structure, then the manufacturing cost is low and the structure is simple, but the ornamental effect and atmospheric impact are limited
Solution Approach 1:
The patent combines multiple functions into a single birthday candle product: traditional burning function, automatic lighting detection function, light emission function, and sound playback function. The control circuit board integrates the light sensor, light source control, and sounder control into one unified system, allowing the candle to simultaneously perform illumination and atmospheric effects while maintaining relatively simple manufacturing processes.
Solution Approach 2:
The birthday candle is designed to perform multiple functions: it can burn traditionally like a regular candle, automatically detect light to trigger effects, emit light through the light source, and play sounds through the sounder. This multi-functional design enhances the ornamental and atmospheric capabilities while keeping the base structure relatively simple.
2Adaptability or versatility
If automatic lighting control and sound effects are added to the birthday candle, then the atmospheric effect and celebratory experience are enhanced, but the device complexity increases
Solution Approach 1:
The light sensor automatically detects the light from the burning wick and triggers the control circuit board without requiring external control or complex programming. The system self-regulates by detecting the presence of flame light and automatically activating or deactivating the light source and sounder based on the burning state, simplifying the control logic while maintaining enhanced atmospheric effects.
3Illumination intensity
If the light source is positioned to illuminate through the hollow channel, then the lighting effect and visual appeal are improved, but the structural complexity of the candle body increases
Solution Approach 1:
The candle body is divided into functional zones: the hollow channel provides a dedicated light path from the light source at the bottom to the upper portion of the candle, separating the illumination function from the structural support function. This segmentation allows the light to travel through a defined path, enhancing the visual effect while keeping the structural additions minimal and purposeful.
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 candle provides a rich and enhanced celebratory atmosphere by automatically controlling light and sound effects in sync with the burning wick, offering a more engaging and beautiful experience.
Implementation Method 1
a light sensor configured in the candle body at a position close to the wick and configured for detecting light generated by the wick when the wick burns
Implementation Method 2
a light source, and a control circuit board electrically connected with the light sensor and the light source
Implementation Method 3
The wick is made of flammable material
Data Source
AI summary
A birthday candle with an automatic lighting effect mainly includes a candle body, a wick connected to the candle body with an end protruding outside an upper end of the candle body, a light sensor configured in the candle body at a position close to the wick and configured for detecting light generated by the wick when the wick burns, a light source, and a control circuit board electrically connected with the light sensor and the light source. The control circuit board is used for controlling the light source according to signals output from the light sensor. The control circuit board turns on the light source once the wick burns and turns off the light source once the wick is extinguished, such that the light source can work synchronously and coordinately along with the wick.
