Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If three-dimensional sensors (stereoscopic imaging elements, three-dimensional scanners, depth sensing devices) are used for body modeling, then measurement precision and three-dimensional body model accuracy are improved, but device cost and complexity increase significantly
Solution Approach 1:
The patent uses two-dimensional images as a simplified copy or representation of the three-dimensional body, processing these 2D images through machine learning models to generate personalized 3D body models. This approach replaces complex 3D sensors with simpler 2D imaging while achieving comparable or superior model accuracy through intelligent algorithms
Solution Approach 2:
The patent replaces mechanical/optical 3D sensing systems with a computational approach using 2D image processing and machine learning. Instead of using physical three-dimensional scanners or stereoscopic devices, the system uses standard 2D cameras combined with AI-based reconstruction algorithms to achieve 3D body modeling
2Device complexity
If traditional body measurement methods (manual measurement, coordination with health experts) are used, then device cost is reduced, but ease of operation and user convenience deteriorate
Solution Approach 1:
The patent enables users to independently perform body composition analysis by simply taking photos with their smartphones. The system automatically processes the images, generates 3D body models, and provides personalized insights without requiring manual measurements or coordination with health experts, making the process entirely self-service oriented
Solution Approach 2:
The patent transforms the body measurement process from manual physical measurements to automated image-based analysis. By changing the input parameter from manual data entry to 2D images, the system automatically extracts body composition parameters through machine learning, significantly improving user convenience while maintaining accuracy
3Device complexity
If exercise programs do not consider individual body characteristics, then program simplicity is maintained, but effectiveness and adaptability deteriorate
Solution Approach 1:
The patent generates personalized exercise and nutrition recommendations tailored to each user's specific body characteristics, such as body fat distribution, muscle mass, and body shape. Instead of using generic exercise programs, the system creates localized recommendations adapted to individual anatomical features, significantly improving program effectiveness
Solution Approach 2:
The patent creates dynamic, adaptive exercise and nutrition programs that automatically adjust based on user progress, body composition changes, and individual characteristics. The system continuously updates recommendations as users progress through their fitness journey, making the program flexible and highly effective rather than static and generic
