Wireless Induction Toothbrush Head With Multi-Wavelength LED Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric toothbrushes lack a light-up function and additional tooth care features, limiting their effectiveness in oral hygiene beyond vibration and bristle cleaning.
Innovation Solution
A wireless induction power supply type light-up electric toothbrush with a toothbrush head featuring LED lamps of different colors (purple, blue, and red) for specific oral care effects, powered by a rechargeable battery via wireless induction, allowing customizable tooth care functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LED lamps are added to the toothbrush head for light-up function and tooth care effects, then the tooth care functionality is improved, but the device complexity increases
Solution Approach 1:
The toothbrush is divided into a handle portion and a replaceable head portion. The LED lamps are integrated into the head portion, which can be independently replaced. This segmentation allows the complex light-up functionality to be isolated to the head portion, making the overall system more manageable and the handle portion simpler.
Solution Approach 2:
The toothbrush head is designed as a universal module that can be replaced to provide different tooth care functions. By placing LED lamps and other functional elements in the replaceable head portion, the same handle can work with different heads for different purposes (cleaning, whitening, gum care, etc.), reducing the complexity of the permanent handle structure.
2Ease of operation
If wireless induction power supply is implemented for the toothbrush head, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The mechanical connection and manual power transfer are replaced with wireless induction power supply. The electromagnetic induction mechanism eliminates the need for physical electrical contacts between the handle and head, simplifying the user operation (no plugging/unplugging) while containing the complexity within the power supply modules.
3Adaptability or versatility
If multiple LED lamps with different wavelengths are integrated into the toothbrush head, then the adaptability for different tooth care needs is improved, but the volume of the toothbrush head increases
Solution Approach 1:
Different LED lamps emitting different wavelengths (purple for gum relief, blue for whitening, red for sterilization) are positioned at specific locations within the toothbrush head corresponding to different functional zones. This local quality approach allows multiple functions to be integrated without uniformly increasing the overall head volume, as each LED is placed only where needed for its specific function.
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 integration of LED lamps with distinct wavelengths enhances gum relief, whitening, and sterilization, providing a more comprehensive oral care experience while enabling convenient replacement and compact design.
Implementation Method 1
the handle emission inductance coil is provided with a handle emission inductance coil, and the handle emission inductance coil is connected to the mainboard through a lead; the toothbrush head cover plate is upwards provided with a toothbrush head receiving inductance coil
Implementation Method 2
the toothbrush head LED panel is arranged with several toothbrush head LED lamps... a light-up band of the purple-light LED lamp is 325 nm-395 nm... a light-up band of the blue-light LED lamp is 480 nm-520 nm... a light-up band of the red-light LED lamp is 630 nm-680 nm
Implementation Method 3
Through rapid rotation or vibration of a core of an electric motor, a toothbrush head of an electric toothbrush is caused to vibrate at a high frequency
