Solution Overview

Problem

Existing virtual try-on applications for cosmetics fail to accurately render color, texture, and shape on individual skin due to lack of personalized calibration, leading to high color deviation and unrealistic cosmetic product simulations.

Innovation Solution

A system utilizing a make-up calibration kit and an artificial neural network to generate personalized virtual try-on experiences by characterizing cosmetic product colors, deviations, and light effects, with a precise applicator for controlled application, and adjusting digital images to account for skin tone and texture variations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a standard virtual try-on application is used, then the application is simple and widely accessible, but the color rendering and texture accuracy are poor due to lack of personalization

Engineering Contradiction:
Improvecolor rendering accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary calibration by capturing reference images of the user's face with and without makeup, and pre-computing personalization parameters including skin tone, texture, and color characteristics. This preliminary action enables accurate virtual try-on without requiring complex real-time processing during actual makeup selection

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts multiple parameters including color values (RGB, HSV spaces), transparency levels, texture maps, and lighting conditions based on the user's personal characteristics. These parameter changes are applied to virtual makeup products to achieve realistic rendering that matches the user's specific skin properties

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If virtual makeup overlay is applied directly without calibration, then the process is fast and simple, but the color deviation from real makeup application is high

Engineering Contradiction:
Improvecolor accuracyVSAvoidcalibration time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The calibration process is performed in advance by capturing reference photos and computing personalization parameters before the actual virtual try-on. This preliminary calibration stores user-specific data that accelerates subsequent makeup selection while maintaining high color accuracy

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from the captured reference images to continuously refine the virtual makeup rendering. By comparing the user's actual skin properties with the virtual application results, the system adjusts color values and transparency to minimize deviation from real makeup appearance

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If the same virtual try-on process is applied to all users, then the system is scalable and easy to operate, but it does not account for individual skin color and texture variations

Engineering Contradiction:
Improvepersonalization capabilityVSAvoiduser convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system automatically performs calibration by capturing user photos and computing personalization parameters without requiring manual input or configuration. This self-service approach enables personalization while maintaining ease of operation, as the user simply needs to provide facial images rather than configure technical parameters

Inventive Principle:
Principle #25Self-service
