Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for camouflaging skin blemishes are either time-consuming and require great accuracy or cannot effectively address blemishes in hard-to-reach areas without assistance.
Innovation Solution
A device equipped with a non-colorimetric detection system responsive to soundwaves, moisture, and other physical parameters, allowing for automatic detection and application of a composition to keratinous materials like skin, enabling accurate and efficient camouflage without the need for extensive user attention or assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a layer of covering composition is deposited to mask non-uniformities by going beyond them in all directions, then the application technique is simple and does not require great accuracy, but the result is not very natural
Solution Approach 1:
The patent applies makeup composition locally only to the detected non-uniform zones rather than uniformly across the entire skin surface. The system uses acoustic detection to identify specific areas with non-uniform reflectance and deposits composition precisely at those locations, achieving both accuracy and efficiency.
2Manufacturing precision
If the non-uniformity is covered in a masking composition in highly accurate manner covering only the blemish itself, then the camouflage result is accurate and natural, but the process requires a great deal of attention and becomes time-consuming
Solution Approach 1:
The patent replaces the manual visual inspection and manual application process with an automated acoustic detection system and automated composition delivery system. The microprocessor-controlled system detects non-uniformities using acoustic waves and automatically controls the composition application, eliminating the need for manual attention while maintaining high precision and speed.
Solution Approach 2:
The system performs both detection and application functions automatically without requiring continuous human intervention. The microprocessor controls the entire process from detecting non-uniformities to depositing composition, enabling the device to serve itself in completing the makeup application task efficiently.
3Manufacturing precision
If help from another person is used to apply composition to zones that are difficult or impossible to see, then accurate application to hard-to-reach areas is achieved, but the process becomes more complex and requires additional resources
Solution Approach 1:
The patent integrates multiple functions into a single handheld device: acoustic wave generation, acoustic signal detection, non-uniformity identification, and composition application. This multi-functional integration allows the device to independently handle all aspects of the makeup application process, including reaching hard-to-access areas, without requiring external assistance or additional complex systems.
