Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If large medical diagnostic devices like MRI machines and CT scanners are used, then measurement precision and reliability are improved, but portability and ease of operation deteriorate
Solution Approach 1:
The patent segments the diagnostic device into a handheld portable unit for field collection and a centralized cloud processing system for analysis. The handheld device captures basic physiological data (heart rate, oxygen saturation, blood pressure) using simple sensors, while complex AI-based diagnostic functions are performed remotely on cloud servers, resolving the contradiction between portability and computational capability requirements
Solution Approach 2:
The patent introduces a cloud-based processing system as an intermediary between the simple handheld device and the complex AI analysis. This intermediary handles the computationally intensive tasks of deep learning model inference, data comparison with standard of care protocols, and diagnostic result generation, allowing the handheld device to remain portable while achieving high measurement precision through sophisticated remote processing
2Adaptability or versatility
If multiple sensors and AI algorithms are integrated into a portable device, then functionality and measurement precision are improved, but device complexity and power consumption increase
Solution Approach 1:
The patent extracts the complex AI processing algorithms, deep learning models, and data comparison functions from the portable handheld device and places them in the cloud environment. The handheld device only contains minimal sensors and processing capability for data collection, while the cloud system provides the sophisticated diagnostic functions, thereby reducing device complexity while maintaining high functionality
Solution Approach 2:
The patent implements a universal cloud-based processing platform that can handle multiple diagnostic functions through a single interface. The cloud system provides standardized AI-based analysis for various conditions (cardiac, respiratory, neurological) using the same handheld device, eliminating the need for multiple specialized devices and reducing overall system complexity while maintaining versatility
3Measurement precision
If AI algorithms with large datasets are processed on-device, then measurement precision and adaptability are improved, but processing power requirements and device complexity increase
Solution Approach 1:
The patent uses the cloud computing infrastructure as an intermediary to provide the necessary processing power for running sophisticated AI algorithms and deep learning models. The cloud servers possess the computational resources required to process large datasets and execute complex neural networks, enabling high measurement precision without requiring the portable device to have equivalent processing capability
Solution Approach 2:
The patent employs pre-trained AI models and diagnostic algorithms that are developed and maintained centrally in the cloud. These models are copied and executed remotely during diagnostic procedures, allowing the handheld device to access sophisticated analytical capabilities without housing the full computational infrastructure or large datasets locally, thereby reducing on-device processing power requirements
4Reliability
If biometric patterns are used for identification, then reliability is improved, but vulnerability to artificial replication increases
Solution Approach 1:
The patent combines multiple biometric verification factors (face recognition, gait analysis, voice recognition) into a composite authentication system. This multi-factor approach creates a composite biometric profile that is much more difficult to replicate artificially than any single biometric characteristic, thereby maintaining high reliability while reducing vulnerability to spoofing attacks
Solution Approach 2:
The patent replaces traditional mechanical biometric scanning with AI-based pattern recognition systems that analyze complex behavioral and physiological characteristics. The AI algorithms detect subtle nuances in gait, facial movements, and voice patterns that are extremely difficult to replicate, providing enhanced security against artificial biometric replication while maintaining identification accuracy

AI summary
An AI-based system and method for supporting differential diagnosis and standard of care in healthcare. The method involves receiving patient information from various sources, including patient-reported symptoms, physician notes, and sensor data from medical devices. The patient information is preprocessed and analyzed using deep learning models to generate a ranked list of potential diagnoses, each associated with likelihood scores and key contributing factors. The potential diagnoses are provided to physicians via an interactive interface, and physician feedback is collected to fine-tune the AI models using reinforcement learning. The method aims to enhance physician decision-making, improve diagnostic efficiency, and ensure adherence to the standard of care by leveraging AI's ability to analyze vast amounts of data more effectively than human physicians.
