Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual breast measurement and bra-fitting methods are limited in accuracy due to variability in breast shapes and sizes, relying on indirect 'best-match' techniques and requiring expensive equipment and controlled environments, making it challenging to provide properly fitting garments without physical try-ons.
Innovation Solution
A computer-implemented method that generates a three-dimensional model of a subject's body from 2D images by extracting features corresponding to standard human anatomy, using non-rigid transforms to align anatomical landmarks, allowing for precise determination of breast morphology parameters such as volume, shape, and position, and adjusting virtual garments for accurate fitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If indirect 'best-match' techniques are used for breast measurement, then the measurement process is simplified, but measurement precision deteriorates due to variability in breast shapes and sizes
Solution Approach 1:
The patent creates a three-dimensional digital model that copies and represents the actual breast morphology. By capturing the breast shape in 3D space and creating a virtual replica, the system achieves precise measurements without requiring physical contact or complex manual measurement processes, thus resolving the contradiction between operational simplicity and measurement accuracy
Solution Approach 2:
The patent transitions from traditional two-dimensional image analysis to three-dimensional modeling. By adding the third dimension, the system can accurately represent breast volume, shape, and position, overcoming the limitations of 2D methods while maintaining ease of operation through automated processing
2Measurement precision
If expensive equipment and controlled environments are used, then measurement precision improves, but device complexity and accessibility worsen
Solution Approach 1:
The patent replaces complex mechanical measurement systems with computational methods. Instead of using expensive physical scanning equipment and controlled environments, the system uses standard digital cameras combined with image processing algorithms and three-dimensional modeling techniques to achieve accurate measurements, thereby reducing device complexity while maintaining precision
Solution Approach 2:
The system enables subjects to perform self-measurement using their own devices. By providing automated feature extraction and three-dimensional model generation, the patent eliminates the need for professional operators or specialized equipment, allowing anyone to obtain accurate breast morphology measurements independently
3Measurement precision
If manual marker identification is used, then measurement accuracy improves, but ease of operation and automation deteriorate
Solution Approach 1:
The patent introduces automated image processing algorithms as an intermediary between the captured image and the final measurement. These algorithms automatically identify anatomical landmarks and extract features, serving as a mediator that replaces manual identification while maintaining accuracy through sophisticated computer vision techniques
Solution Approach 2:
The system transforms the measurement process by changing from manual parameter identification to automated parameter extraction. By using algorithms that automatically detect and measure anatomical features, the patent achieves both high precision and full automation, eliminating the trade-off between accuracy and ease of operation
