Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional imaging systems are used to scan organs, then scanning can be performed, but the systems cannot automatically differentiate between different organs due to anatomical feature similarities, leading to significant error in scanning results
Solution Approach 1:
The patent segments the organ identification process into multiple analysis stages: initial scan data acquisition, feature extraction from anatomical structures, classification algorithm application, and result verification. This multi-stage segmentation allows each stage to focus on specific differentiation tasks, improving overall organ identification accuracy by breaking down the complex differentiation problem into manageable components.
Solution Approach 2:
The patent introduces classification algorithms as an intermediary between raw scan data and final organ identification. These algorithms act as mediators that process the scan data, apply learned patterns from training datasets, and produce differentiated organ identifications. This intermediary processing layer enables accurate differentiation of organs with similar anatomical features by applying computational intelligence rather than relying solely on conventional imaging thresholds.
2Measurement precision
If multiple specialized systems are used to scan different organs, then detailed scanning of specific organs can be achieved, but the systems become expensive to manufacture and require specialized training for each individual operating the system
Solution Approach 1:
The patent creates a universal scanning system that can identify multiple different organ types using a single integrated platform. The system employs a common hardware infrastructure combined with software-based classification algorithms that can be configured to identify various organs including heart vessels, liver vasculature, and femoral arteries. This multi-functional approach eliminates the need for multiple specialized systems while maintaining detailed scanning capability across different organ types.
Solution Approach 2:
The patent utilizes parameter changes in the classification algorithms to adapt the single system to different organ identification tasks. By modifying algorithm parameters, training datasets, and feature extraction parameters rather than changing physical hardware, the system can switch between identifying different organ types. This parameter-based adaptability allows one system to perform the functions previously requiring multiple specialized systems.
3Reliability
If conventional systems are designed for individual organs to limit error, then scanning accuracy for that specific organ improves, but the systems lack the capability to be programmed for new tasks and cannot be updated with latest scanning technologies
Solution Approach 1:
The patent implements a dynamic system where the classification algorithms can be continuously updated and retrained with new data. The system transitions from static, hardwired organ identification to a dynamic architecture where algorithm parameters, decision thresholds, and training datasets can be modified to incorporate latest scanning technologies and address new identification tasks. This dynamic nature allows the system to maintain high reliability for established organs while adapting to new organ types and scanning methodologies.
Solution Approach 2:
The patent enables the system to self-update through automated retraining processes where the classification algorithms can be retrained on new datasets without requiring complete system redesign. The system incorporates mechanisms to learn from new scanning data, automatically adjust parameters, and improve performance over time. This self-service capability allows continuous improvement of scanning accuracy and adaptation to new tasks without proportionally increasing system complexity.
