Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual or visual analysis by experts is used to determine coloration parameters, then the process is simple and accessible, but the precision and accuracy of the determination is poor
Solution Approach 1:
The patent replaces manual visual analysis by experts with an automated image processing system. A camera captures images of the body zone, and computer algorithms automatically analyze coloration parameters, eliminating human subjectivity and improving measurement precision while maintaining operational simplicity through automation.
Solution Approach 2:
The patent creates a digital copy (image) of the body zone instead of requiring direct physical measurement or manual inspection. The captured image serves as a data representation that can be processed by computers to extract coloration parameters with high precision, replacing the need for complex manual assessment tools.
2Measurement precision
If objective measurements using colorimetric devices are used, then measurement precision is improved, but the complexity of the determining device increases
Solution Approach 1:
The patent employs a standard camera device that can perform multiple functions: capturing images, storing data, and enabling virtual try-on capabilities. This multi-functional approach replaces the need for specialized colorimetric equipment, achieving high measurement precision without increasing device complexity, as the same camera serves both documentation and analytical purposes.
Solution Approach 2:
The patent introduces an image as an intermediary between the physical body zone and the coloration parameter determination. Instead of directly measuring coloration with complex instruments, the system captures visual information through a simple camera and processes this intermediate data to extract precise coloration parameters, simplifying the overall measurement system.
3Ease of operation
If virtual try-on software is used to simulate make-up effects, then product selection is assisted, but the rendering accuracy may not reflect real-world results
Solution Approach 1:
The patent implements a feedback mechanism where the system captures actual images of the body zone with applied coloration, compares these with the simulated virtual try-on results, and uses this feedback to refine and improve the rendering accuracy. This iterative process ensures that the virtual simulations increasingly reflect real-world outcomes, enhancing both ease of operation and rendering precision.
Solution Approach 2:
The patent performs preliminary capture of the body zone's actual coloration and storage of reference data before the virtual try-on process. By pre-acquiring and analyzing the actual coloration characteristics, the system can more accurately simulate and predict the effects of different coloration products, improving rendering accuracy while maintaining user-friendly operation.
