Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bio-information processing devices rely on indirect estimation methods, which can lead to inaccuracies in measuring bio-signals like blood pressure, necessitating correction using more reliable devices like sphygmomanometers for precise measurements.
Innovation Solution
A bio-information processing apparatus that measures bio-signals, synchronizes them with reference bio-information, and corrects estimated bio-information using an offset parameter adjustment based on measurement circumstances, including time synchronization and pre-generated correction models, to enhance accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If indirect estimation method is used to measure bio-information, then measurement convenience is improved, but measurement precision deteriorates
Solution Approach 1:
The system continuously monitors bio-signals and compares estimated bio-information with reference values, using the comparison results to dynamically adjust and refine the estimation algorithm, thereby improving precision while maintaining non-invasive measurement convenience
Solution Approach 2:
The system changes multiple parameters including offset parameters, gain parameters, and measurement conditions based on individual subject characteristics and environmental factors, allowing the estimation model to adapt and improve precision without requiring invasive procedures
2Measurement precision
If correction using reference device is applied, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The processing apparatus integrates multiple functions including bio-signal measurement, reference value reception, synchronization, offset correction, and continuous monitoring within a single device, eliminating the need for separate correction devices and reducing overall system complexity
Solution Approach 2:
The system uses a processing apparatus that acts as an intermediary between the bio-signal measurer and the reference device, automatically synchronizing and correcting data without requiring direct complex interactions between multiple independent devices
3Measurement precision
If synchronization and offset correction are performed, then measurement precision is improved, but processing time increases
Solution Approach 1:
The system performs preliminary synchronization and offset correction setup during initial calibration phases, so that subsequent continuous measurements can be corrected more quickly using pre-established parameters and models
Solution Approach 2:
The system performs continuous background processing and real-time correction during measurement, rather than performing corrections in separate batch processing steps, thereby minimizing interruption to the measurement flow and reducing effective processing time
