Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a physician manually analyzes all physiological measurement values and applies multiple diagnostic algorithms, then comprehensive diagnostic accuracy is improved, but the time required and complexity of analysis increases significantly
Solution Approach 1:
The patent introduces an intermediary system (computerized exercise test interpretation system) that mediates between the raw physiological data and the physician's diagnostic decision-making. This system automatically processes measurement values, applies diagnostic algorithms, and generates interpretation statements, thereby maintaining diagnostic accuracy while significantly reducing the time required for manual analysis.
Solution Approach 2:
The system enables self-service by allowing the exercise test data to automatically undergo processing and interpretation through predefined algorithms and rules. The system autonomously generates interpretation statements and reasoning texts without requiring manual intervention for each analysis step, thus reducing physician workload and analysis time while maintaining comprehensive diagnostic evaluation.
2Measurement precision
If multiple diagnostic algorithms and physiological measurement values are utilized, then diagnostic completeness is improved, but the complexity of the analysis system increases
Solution Approach 1:
The patent segments the complex diagnostic analysis into distinct, manageable components: individual physiological measurement values are processed separately through specific algorithms, and interpretation statements are generated for each measured parameter. This segmentation allows the system to handle multiple measurements and algorithms in an organized manner, reducing perceived complexity while maintaining diagnostic completeness.
Solution Approach 2:
The system employs universal diagnostic algorithms that can process multiple different physiological measurement values through the same analytical framework. The interpretation system is designed to handle various types of data (ECG, blood pressure, heart rate, etc.) using a unified approach, thereby managing system complexity while achieving comprehensive diagnostic evaluation across multiple parameters.
3Loss of information
If comprehensive physiological measurements are collected during exercise stress test, then diagnostic information quality is improved, but the difficulty of interpreting and managing the data increases
Solution Approach 1:
The computerized interpretation system serves as an intermediary that bridges the gap between comprehensive raw data collection and easy data interpretation. It automatically processes the large volume of physiological measurements, applies appropriate algorithms, and transforms the complex data into user-friendly interpretation statements and reasoning texts, thereby preserving information quality while dramatically improving ease of operation for physicians.
Solution Approach 2:
The patent replaces the manual mechanical process of data interpretation with an automated computational system. Instead of physicians manually analyzing each measurement value and applying algorithms, the system uses computerized processing to automatically generate interpretations, thereby maintaining high information quality while significantly improving ease of operation.
4Ease of operation
If a single test or algorithm is used for ECG interpretation, then simplicity of the testing process is maintained, but the ability to distinguish between healthy and pathological conditions decreases
Solution Approach 1:
The patent merges multiple diagnostic algorithms and measurement analyses into a unified interpretation system. Rather than requiring separate tests or algorithms to be evaluated independently, the system combines them into an integrated workflow that automatically processes all relevant data together, maintaining testing simplicity while improving pathology detection accuracy through the synergistic application of multiple algorithms.
Data Source
AI summary
A system and method for the efficient implementation of a complex exercise test is disclosed. A rule interpreter synthesizes interpretation statements based upon the processing of collected physiological data and user entered data with a series of exercise test interpretation rules. These statements aid a clinician in interpreting exercise test results by identifying detected abnormal or borderline conditions.
