Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional 2D image capture methods are used, then the system complexity is low, but the measurement precision of body anatomy is insufficient
Solution Approach 1:
The patent transitions from traditional 2D image capture to 3D depth mapping by introducing a depth camera that captures spatial information in the third dimension. This enables precise measurement of body anatomy including height, width, and depth parameters, resolving the measurement precision issue while the integrated kiosk design keeps system complexity manageable.
Solution Approach 2:
The patent replaces complex mechanical measurement systems with optical-based depth camera technology. The depth camera uses structured light or time-of-flight methods to capture 3D body geometry without requiring physical contact or complex mechanical scanning apparatus, thus improving measurement precision while maintaining reasonable system complexity.
2Productivity
If manual body measurement methods are used, then the equipment cost is low, but the productivity of avatar creation is reduced
Solution Approach 1:
The system enables self-service avatar creation where users independently complete the measurement process by standing in front of the depth camera. The automated capture and processing eliminate the need for operators, significantly improving productivity while the turnkey kiosk solution keeps deployment complexity manageable.
Solution Approach 2:
The system performs preliminary 3D body scanning and measurement automatically before the user even begins avatar customization. This pre-processing of anatomical data accelerates the overall avatar creation workflow, improving productivity while the automated nature reduces operational complexity.
3Manufacturing precision
If simple avatar creation methods are used, then the ease of operation is high, but the manufacturing precision of body-representative avatars is reduced
Solution Approach 1:
The system automatically captures 3D depth information and generates dimensionally accurate avatars without requiring users to manually input measurements or perform complex positioning. The depth camera and processing algorithms handle the complexity, providing high manufacturing precision while maintaining ease of operation through automated workflows.
Solution Approach 2:
Complex manual measurement and modeling tasks are replaced with automated computer vision and 3D reconstruction algorithms. The system processes depth camera data automatically to generate precise avatar geometries, achieving high manufacturing precision while users only need to stand still for scanning, maintaining ease of operation.
4Measurement precision
If physical fitting rooms are used, then the measurement precision is high, but the loss of time for customers is increased
Solution Approach 1:
The patent replaces physical fitting room infrastructure with a digital 3D scanning and virtual try-on system. The depth camera captures body measurements in seconds, and virtual garments are instantly rendered on the avatar, eliminating the time-consuming process of physically trying on multiple items while maintaining measurement accuracy through automated 3D reconstruction.
Solution Approach 2:
The system creates a digital 3D copy of the user's body geometry that can be used for virtual fitting. This digital twin captures accurate body measurements instantly, replacing the need for repeated physical measurements in fitting rooms and significantly reducing the time customers spend on the fitting process while maintaining precision.
