Innovation Solution
A handheld LED therapy device featuring a multilight cup with at least one light color, connected to a main controlling module that includes a single-chip microcomputer IC circuit and MOS transistors, allowing for simultaneous control of multiple LED therapy lights, including turning on/off, adjusting wavelengths, and setting timers, enhancing light output and therapy efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single LED light cup is used, then the device structure is simple, but the therapy effect is poor due to single light emission
Solution Approach 1:
The single LED light cup is segmented into multiple LED light cups, each emitting different wavelengths of light. This segmentation allows the device to provide comprehensive light therapy coverage while maintaining a modular structure that doesn't overly complicate the overall device design.
Solution Approach 2:
The device is designed with multi-functional LED light cups that can emit multiple wavelengths simultaneously. This multi-functionality enables a single device to address various skin concerns (anti-aging, acne treatment, wound healing) without requiring multiple separate devices, thus improving therapy effectiveness while keeping the device structure manageable.
2Reliability
If multiple LED light cups are used, then the therapy effect is improved, but the device structure becomes complex
Solution Approach 1:
Multiple LED light cups are merged into a single integrated handheld device with unified control. The control module consolidates the operation of all LED cups, and the power supply system is combined into a single battery unit, reducing structural complexity despite having multiple light emission components.
Solution Approach 2:
The multiple LED light cups are arranged in a nested or compact configuration within the handheld device body. This nesting approach maximizes the use of space, allowing multiple light cups to be housed in a compact form factor without significantly increasing the overall device size or structural complexity.
3Productivity
If multiple LED light cups with different wavelengths are used, then the light output and therapy efficacy are enhanced, but the control system complexity increases
Solution Approach 1:
The control module is designed as a universal controller that can manage multiple LED light cups with different wavelengths through a single interface. This multi-functional control system can switch between different wavelength combinations and operate in various modes (single wavelength, dual wavelength, multi-wavelength simultaneous operation) without requiring separate control circuits for each LED cup.
Solution Approach 2:
The control system utilizes parameter changes in the PWM duty cycle to regulate the intensity and activation of different LED wavelengths. By varying the duty cycle parameters, the system can control which wavelengths are active and at what intensity, providing versatile therapy options without increasing hardware complexity.
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 device offers improved light output and therapy effects by utilizing multiple LED colors with adjustable wavelengths, promoting skin metabolism, collagen production, tissue repair, and pain relief, meeting consumer demands for beauty and therapy benefits.
Implementation Method 1
A LED therapy device uses the principle of photo-dynamics to activate deep cells, facilitating the metabolism of skin. After the light is absorbed by the skin, the light energy is converted into intracellular energy
Implementation Method 2
the light energy is converted into intracellular energy, which relaxes and strengthens the capillaries and produces a photo-chemical reaction-enzymatic reaction with the skin, which increases the content of glycogen and protein
