Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a non-invasive, painless, and safe method to rejuvenate and reconstruct the lining walls of body cavities such as the vagina, which have lost elasticity and tone due to aging or pathological conditions, without causing excessive heating or cancerogenic effects, and ensuring reliable operation and sterility.
Innovation Solution
A photobiomodulation device and system using a probe with a three-dimensional array of light sources, preferably LEDs, emitting specific wavelengths of light within the visible spectral range, applied in continuous wave or pulse mode, to stimulate collagen and elastin production, enhance blood circulation, and improve tissue elasticity and moisture, with a control unit to adjust operational parameters like intensity and duration of illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If pulsed light is used to heat and shrink collagen in the skin, then skin elasticity is improved, but excessive heating and thermal injury may occur
Solution Approach 1:
The patent applies periodic pulsed light irradiation instead of continuous light exposure. The light source emits light in repeated pulses with specific duration intervals, allowing tissue heating during pulse exposure and cooling during intervals, thereby achieving collagen contraction and skin tightening while preventing excessive temperature rise and thermal injury to surrounding tissues.
2Productivity
If high intensity light is used to achieve therapeutic effects, then treatment efficiency is improved, but risk of cancerogenic effects and tissue damage increases
Solution Approach 1:
The patent utilizes specific wavelength parameters (red light at 630-680nm and near-infrared light at 780-1500nm) that are absorbed by cytochromes in mitochondria to stimulate cellular metabolism and ATP production. By changing the light parameters to these specific wavelengths and applying them in pulsed mode with controlled intensity, the treatment achieves therapeutic effects while avoiding the harmful effects associated with higher intensities or inappropriate wavelengths.
3Object-affected harmful factors
If cooling is applied to protect epidermis during pulsed light treatment, then skin safety is improved, but treatment complexity increases
Solution Approach 1:
The patent employs a transparent cooling substance (such as gel or liquid coolant) as an intermediary layer applied to the skin surface before light irradiation. This cooling medium serves as a mediator that absorbs excess heat from the light treatment, protecting the epidermis from thermal damage while allowing the therapeutic light to penetrate and reach the deeper dermal layers where collagen resides.
4Manufacturing precision
If multiple pulses and controlled delay timing are used to control temperature distribution, then treatment precision is improved, but operational complexity increases
Solution Approach 1:
The patent incorporates control systems that regulate the timing, duration, and intensity of light pulses based on predetermined protocols. The system controls the delay between coolant application and light irradiation, as well as the interval between multiple pulses, to achieve optimal temperature distribution in the tissue. This feedback-controlled approach ensures precise temperature management while simplifying operator intervention through automated sequencing.

Function Achieved in This Case
The method effectively rejuvenates vaginal walls by increasing elasticity and firmness, reducing vaginal diameter, and improving sexual satisfaction, while also treating conditions like bacterial vaginosis and hemorrhoids, and enhancing mucous membrane health without thermal injury or systemic side effects.
Implementation Method 1
light interferes with a number of cellular processes, including protein synthesis (e.g. collagen production), cell growth and differentiation, cell motility, membrane potential and binding affinities, neurotransmitter release, ATP synthesis
Implementation Method 2
applying pulsed light to the skin to heat and shrink collagen within the skin, thereby reviving the elasticity of the collagen and of the skin
