Selective Topical Composition Applicator Using Dynamic Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual application of topical compositions is imprecise, leading to undesirable appearances and wastage, as it often results in a continuous film over large skin areas, decreasing breathability and increasing the risk of allergic reactions.
Innovation Solution
A method and device that use image data analysis to selectively apply a composition by identifying and targeting areas with undesirable visual effects, applying a predetermined amount of a reflectance modifying agent to reduce artifact magnitude, with adjustable threshold values based on deposition rate and user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual application of topical composition is used, then ease of operation is improved, but manufacturing precision deteriorates
Solution Approach 1:
The patent replaces manual mechanical application with an automated system that uses image processing and computer control to detect skin artifacts and precisely apply composition only to affected areas, eliminating the imprecision of manual application while maintaining ease of use through automation
Solution Approach 2:
The system automatically detects skin artifacts through image processing and self-regulates the application process, eliminating the need for manual judgment and application while ensuring precise targeting of treatment areas
2Reliability
If heavy application of composition is used to cover artifacts, then artifact reduction is improved, but loss of substance worsens
Solution Approach 1:
The system applies composition with local quality by targeting only the specific artifact-affected areas detected through image processing, rather than applying uniformly across the entire treatment area, thereby reducing material waste while maintaining effective coverage where needed
Solution Approach 2:
The system uses partial action by applying composition only to the extent necessary for covering detected artifacts, avoiding excessive application to areas that do not require treatment, thus preventing material waste while ensuring adequate coverage of problem areas
3Reliability
If composition is applied over large portions of skin, then artifact reduction is improved, but object-generated harmful factors worsen
Solution Approach 1:
The system applies composition locally only to detected artifact areas rather than over large portions of skin, minimizing the surface area exposed to potential allergens while still achieving effective coverage of treatment areas
Solution Approach 2:
The system uses partial action by limiting composition application to only the necessary areas for artifact coverage, avoiding unnecessary exposure of healthy skin to potential allergens while maintaining adequate treatment coverage
4Reliability
If continuous film of composition is applied, then artifact coverage is improved, but object-generated harmful factors worsen
Solution Approach 1:
The system creates localized coverage only where artifacts are detected, forming a continuous film only in necessary areas rather than over the entire treatment surface, thereby maintaining skin breathability in untreated areas while achieving uniform coverage where needed
Solution Approach 2:
The system applies continuous film coverage partially, only to the extent necessary for artifact concealment, avoiding excessive application that would create continuous film over healthy skin and compromise breathability
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
Reduces waste and enhances aesthetic appearance by applying the composition only where needed, minimizing exposure to potential allergens and maintaining natural skin appearance while reducing the overall amount of composition used.
Implementation Method 1
the artifact magnitude is determined based on a reflectance of the treatment surface detected in the image
Data Source
AI summary
A device and method for selectively applying a composition a treatment surface (e.g., skin) to impart an aesthetically pleasing appearance to the surface. The device may include a detector for obtaining image data corresponding to an image of an area of skin. The device may also include an applicator for selectively applying a fixed amount of the composition to the skin to a location within the area of skin as determined by the device. The fixed amount is selected to reduce the artifact magnitude by a predetermined coverage level when applied to the skin. The device may include a processing arrangement for receiving image data from the detector, determining an artifact magnitude of the location based on the image data, comparing the artifact magnitude to a threshold, and directing the applicator to apply the composition to the skin when the artifact magnitude is above the threshold.
