Digital Twin Updating via Personalized Parameter Model
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital twin models for patients are often incomplete or inaccurate due to limited initial data, necessitating updates that typically require controlled medical tests, which can be inconvenient and costly.
Innovation Solution
A method using sensor data collected over time to create a personalized parameter model that evaluates dynamic behavior and lifestyle factors, allowing for the digital model to be updated without requiring the patient to visit a medical facility, by linking observed parameter trends to behaviors and updating test protocols and digital models accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If controlled medical tests are used to update digital twin models, then measurement precision and reliability are improved, but ease of operation and loss of time increase due to patient visits to medical facilities
Solution Approach 1:
The patent creates a digital twin (digital copy) of the patient that can be updated remotely using sensor data from the patient's environment, eliminating the need for the patient to physically visit medical facilities while maintaining model accuracy through continuous data collection and processing
Solution Approach 2:
The patent introduces sensors and a digital model as intermediaries between the patient and the medical update process. These intermediaries collect and process physiological data remotely, allowing model updates without direct patient involvement in the testing process
2Measurement precision
If controlled medical tests are used to update digital twin models, then measurement precision is improved, but loss of time increases due to scheduling and visiting medical facilities
Solution Approach 1:
The patent implements continuous data collection through sensors that monitor the patient's physiological parameters in real-time during daily activities, allowing the digital twin to be updated continuously without interruption, eliminating the discrete time loss associated with scheduled medical visits
Solution Approach 2:
By using the digital twin as a copy that can be updated remotely, the system eliminates the time required for patients to travel to and from medical facilities, as all updates occur in the digital domain using data collected from wearable or environmental sensors
3Measurement precision
If comprehensive sensor data collection is implemented, then manufacturing precision and measurement precision improve, but device complexity increases
Solution Approach 1:
The patent segments the data collection and processing system into multiple independent components: sensors for data collection, a digital model for processing, and update mechanisms for refinement. This modular approach manages complexity by allowing each component to be developed and maintained independently while working together to achieve high measurement precision
