Sunscreen Formulation with UV-Responsive Marker for Coverage Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals face challenges in verifying the coverage and effectiveness of sunscreen applications, as existing formulations are not visible and provide imperfect protection against ultraviolet radiation, leading to potential sunburns and long-term skin damage due to inadequate protection from UVA and UVB rays.
Innovation Solution
A sunscreen formulation incorporating an active ingredient that absorbs ultraviolet radiation and a marker that generates a detectable signal when exposed, allowing for real-time analysis of UV protection via an interrogator and analyzer system, which provides recommendations for further protection based on the intensity of the signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sunscreen formulation uses invisible active ingredients to absorb ultraviolet radiation, then skin protection against UVA and UVB rays is provided, but the coverage and effectiveness cannot be verified by the user
Solution Approach 1:
The patent incorporates markers that change color or emit detectable signals when exposed to UV radiation, allowing users to visually verify sunscreen coverage and effectiveness. These markers provide real-time feedback on protection status without compromising the active ingredients' UV absorption capabilities
Solution Approach 2:
The patent uses marker substances as intermediaries between the active UV-absorbing ingredients and the user's perception system. These markers do not replace the active ingredients but work alongside them to provide visible indication of coverage and protection status
2Reliability
If sunscreen formulations provide imperfect protection against ultraviolet radiation, then some skin protection is achieved, but sunburns and long-term skin damage can still occur due to inadequate protection
Solution Approach 1:
The patent implements a feedback mechanism where markers provide real-time information about sunscreen coverage quality and UV exposure levels. This allows users to identify inadequate coverage areas and reapply sunscreen promptly, preventing sunburn and long-term damage before they occur
Solution Approach 2:
The patent enables users to verify coverage immediately after application and throughout exposure periods, allowing for timely reapplication before protection becomes inadequate. This preliminary verification prevents the development of sunburn and cumulative skin damage
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 system enables users to assess and improve their UV protection by detecting the marker's signal, indicating the active ingredient's efficacy and recommending reapplication, thus enhancing skin protection against UVA and UVB radiation.
Implementation Method 1
an active ingredient configured to absorb ultraviolet electromagnetic radiation
Implementation Method 2
a marker configured to absorb ultraviolet electromagnetic radiation and configured to generate a detectable signal in response to the marker absorbing ultraviolet electromagnetic radiation
