Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If static measurements are used for virtual try-on, then the system complexity is reduced, but the accuracy of fit assessment deteriorates
Solution Approach 1:
The patent transitions from static measurements to dynamic 3D body scanning that captures the actual shape and contours of the human body. The system uses multiple cameras to capture images from different angles and reconstructs a dynamic 3D model of the body, allowing for accurate real-time fit assessment while maintaining manageable system complexity through automated processing.
Solution Approach 2:
The patent creates a digital 3D copy (avatar) of the consumer's body that can be used for virtual try-on. This digital twin accurately represents the consumer's body shape, measurements, and proportions, enabling precise fit assessment without requiring physical garment trials. The avatar serves as a realistic replica that maintains the complexity benefits of digital processing while achieving high measurement precision.
2Measurement precision
If real-time 3D body scanning is implemented, then the accuracy of size prediction is improved, but the processing time increases
Solution Approach 1:
The patent performs preliminary 3D body scanning and avatar creation before the actual virtual try-on process. The system captures the consumer's body data in advance, processes it into a standardized 3D model, and stores it for rapid retrieval during shopping. This preliminary action eliminates the need for time-consuming scanning during the try-on experience, reducing processing time while maintaining high accuracy.
Solution Approach 2:
The patent replaces traditional manual measurement methods with automated optical 3D scanning systems. Multiple cameras and image processing algorithms automatically capture and analyze body geometry, eliminating the need for manual tape measurements and reducing human error. This substitution of mechanical/manual processes with automated optical systems significantly reduces processing time while improving measurement precision.
3Loss of information
If multiple cameras are used for 3D scanning, then the completeness of body data is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple camera systems into a unified 3D scanning setup where cameras are positioned at specific angles around the scanning area. The system combines images from multiple cameras through image processing algorithms to reconstruct a complete 3D model of the body. This merging approach captures comprehensive body data from all angles while managing system complexity through integrated hardware and software design.
Solution Approach 2:
The patent designs the multi-camera system to serve multiple functions: capturing front, back, and side views; generating 3D body models; extracting precise measurements; and creating virtual avatars. The same camera array and processing system handle all these tasks, making the increased device complexity worthwhile by providing comprehensive body data completeness and eliminating the need for separate scanning systems for different purposes.
