Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the system generates and stores comprehensive data during the procedure, then the information available for analysis is improved, but the data clutter increases making it difficult to determine termination reasons
Solution Approach 1:
The patent extracts only the essential termination reason information from the comprehensive procedure data. When a procedure terminates prematurely, the system presents a simplified interface that captures only the specific reason for termination (e.g., patient discomfort, technical issue) rather than requiring analysis of all generated data. This extraction principle resolves the contradiction by isolating the critical information needed while eliminating data clutter.
Solution Approach 2:
The patent segments the data handling process into distinct phases: comprehensive data collection during the procedure, then focused termination reason capture upon termination. The system divides the information management task into routine procedure monitoring and specific termination documentation, allowing each segment to handle appropriate data volume without overwhelming the operator.
2Reliability
If the system implements comprehensive data collection and analysis capabilities, then the ability to monitor procedure conditions is improved, but the ease of operation deteriorates due to increased operator burden
Solution Approach 1:
The system performs self-service by automatically monitoring all procedure parameters and detecting conditions that may lead to premature termination. The comprehensive data collection and analysis run autonomously without requiring continuous operator intervention. When termination occurs, the system simply needs the operator to select or input the termination reason, maintaining high monitoring reliability while minimizing operational burden.
Solution Approach 2:
The patent introduces an intermediary layer between comprehensive data collection and operator decision-making. The system automatically processes and analyzes all procedure data, then presents only the essential termination reason options to the operator. This intermediary processing layer maintains reliable monitoring while shielding the operator from data complexity.
3Measurement precision
If the system provides detailed data and alerts during the procedure, then the measurement precision of procedure conditions is improved, but the difficulty of detecting and measuring termination reasons increases
Solution Approach 1:
The system performs preliminary action by continuously monitoring and analyzing all procedure parameters throughout the procedure, maintaining precise measurement of conditions. When termination occurs, this pre-collected data has already identified any anomalies, but the system simplifies the final step by presenting only the termination reason options rather than requiring operators to analyze all the precise measurement data themselves.
