Fluid Dispenser With Integrated LED Light Therapy Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skin treatment dispensers lack the ability to effectively prepare, treat, and optimize the skin during and after fluid application, as they do not incorporate light therapy which is known to have anti-inflammatory and skin-regeneration stimulating effects.
Innovation Solution
A fluid dispenser is designed with a module containing a light-emitting diode (LED) that emits monochromatic light in the 400 nm to 700 nm spectrum, integrated into a compact, ergonomic device resembling a pen, allowing for simultaneous fluid application and skin treatment, with the light being guided through a transparent application wall to ensure consistent exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional dispenser is used for fluid application, then the fluid can be applied to the skin, but the skin cannot be prepared or treated simultaneously to optimize treatment effectiveness
Solution Approach 1:
The patent combines a conventional fluid dispenser with a light therapy device into a single integrated applicator. The dispenser includes both fluid delivery mechanisms and light-emitting components (LEDs or lasers) that can simultaneously apply fluid and deliver light therapy to the skin, thereby preparing and treating the skin during the same application process.
Solution Approach 2:
The applicator is designed to perform multiple functions: it can dispense fluid, deliver light therapy, and potentially combine both functions simultaneously. This multi-functional design allows the device to prepare skin, apply treatment, and enhance absorption all in one step, improving treatment effectiveness without requiring separate devices.
2Reliability
If light therapy components are added to the dispenser, then skin treatment effectiveness is enhanced, but the device complexity increases
Solution Approach 1:
The light therapy components (light source, housing, application surface) are merged with the existing dispenser structure. The light-emitting elements are integrated into the dispenser body or applied surface, allowing both fluid delivery and light therapy functions to share common structural elements, thereby minimizing the increase in device complexity.
Solution Approach 2:
The application surface serves dual purposes: it is both the surface against which the user applies the dispenser and the medium through which light is delivered to the skin. This multi-functional design reduces the need for separate components, keeping the device relatively simple while providing enhanced treatment capabilities.
3Reliability
If the light source is placed close to the skin for effective treatment, then treatment efficacy improves, but accidental exposure to sensitive areas increases
Solution Approach 1:
The light is delivered through the application surface at the specific location where the user intentionally applies the dispenser to the skin. This localized delivery ensures that light exposure occurs only at the intended treatment area, not in surrounding sensitive areas, thereby maintaining treatment efficacy while preventing accidental exposure.
Solution Approach 2:
The application surface acts as an intermediary between the light source and the skin. The light passes through this surface only at the point of contact, providing a controlled and localized treatment area. This intermediary structure prevents stray light from reaching sensitive areas while maintaining effective treatment at the intended site.
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 light therapy enhances the effectiveness of skin treatment by stimulating collagen synthesis, improving vascularization, and accelerating skin repair, while maintaining ease of use and preventing accidental exposure to sensitive areas.
Implementation Method 1
a module comprising at least one source of radiation, such as an LED, each emitting monochromatic light in the spectrum lying in the range 400 nm to 700 nm, and having an anti-inflammatory action and/or a stimulating action for stimulating skin-regeneration metabolisms
Implementation Method 2
Infrared light is thermal radiation at a wavelength of about 700 nm or longer. The light heats the area being treated, stimulates blood circulation, heats tissues, and activates fibroblasts
Implementation Method 3
the light being guided through a transparent application wall to ensure consistent exposure
