Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a stationary multi-camera system is used to capture motion data, then measurement precision is improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent replaces the mechanical multi-camera system with a mobile device using computational photography and image processing algorithms. The mobile device captures motion data through a single camera or fewer cameras, using software-based tracking of visual markers and sensors instead of multiple physical cameras, thereby reducing system complexity while maintaining measurement precision
Solution Approach 2:
The patent uses visual markers and sensors that create optical copies or representations of motion data. These markers are captured by the camera and processed to extract motion information, allowing a single camera to capture data that would traditionally require multiple cameras, thus simplifying the system while preserving measurement accuracy
2Measurement precision
If a stationary multi-camera system is used to capture motion data, then measurement precision is improved, but portability deteriorates
Solution Approach 1:
The patent replaces the fixed mechanical installation of multiple cameras with a portable mobile device that can be easily transported and deployed. The mobile device uses computational methods to achieve motion capture functionality that traditionally required a stationary multi-camera system, enabling portability while maintaining measurement precision through software-based tracking and processing
Solution Approach 2:
The mobile device serves multiple functions: it acts as a camera, a computer for processing motion data, and a display device. This multi-functionality allows a single portable device to replace the entire stationary multi-camera system, enabling the system to be used in various locations including athletic events, clinics, and training facilities without requiring fixed installation
3Measurement precision
If motion capture data is analyzed on a per user basis in a laboratory, then analysis accuracy is improved, but productivity deteriorates
Solution Approach 1:
The patent implements immediate feedback by processing and displaying motion capture data in real-time or near-real-time on the mobile device. The system provides instant analysis results, equipment fitting recommendations, and performance feedback to users without requiring laboratory-based batch processing, thereby maintaining analysis accuracy while dramatically improving productivity and enabling on-site decision making
Solution Approach 2:
The mobile device performs automated analysis of motion capture data using built-in processing capabilities and algorithms. The system automatically tracks visual markers, calculates motion parameters, and generates insights without requiring manual laboratory analysis, enabling users to obtain accurate analysis results immediately in the field rather than waiting for post-laboratory processing
4Measurement precision
If multiple cameras are used to capture three-dimensional points of movement, then measurement precision is improved, but loss of information increases due to data management complexity
Solution Approach 1:
The patent replaces the need for multiple cameras with a single mobile device camera by using computational methods to extract three-dimensional motion information. The system processes visual marker data and sensor readings through algorithms that reconstruct 3D motion from 2D images, maintaining measurement precision while eliminating the data management complexity associated with coordinating and processing data from multiple cameras
