Blood Pressure Fluctuation Detection in Wearable Health Monitors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable blood pressure monitors do not effectively notify users of blood pressure fluctuations that occur due to environmental changes, such as rapid temperature changes, which are important for health management.
Innovation Solution
An information processing apparatus that acquires and compares blood pressure information over time, detects fluctuations exceeding a reference value, and outputs notification information, including environmental changes, to alert users of potential health impacts and encourage lifestyle adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If blood pressure measurement is performed easily in various situations using a wearable monitor, then measurement convenience is improved, but blood pressure fluctuations occurring in daily life are not noticed
Solution Approach 1:
The system automatically compares current blood pressure measurements with past measurements and provides feedback to the user when fluctuations exceeding a reference value are detected. This feedback mechanism ensures that users become aware of blood pressure fluctuations that occur during daily life, resolving the contradiction between easy measurement and fluctuation awareness.
Solution Approach 2:
The wearable blood pressure monitor performs self-service by automatically acquiring blood pressure information, comparing it with stored past data, detecting fluctuations, and notifying the user without requiring manual intervention. This enables the system to maintain measurement convenience while simultaneously providing fluctuation awareness through automated processing.
2Measurement precision
If manual comparison of past and current blood pressure values is required to notice fluctuations, then fluctuation detection accuracy is improved, but user burden increases
Solution Approach 1:
The system performs the comparison operation automatically by itself. The blood pressure measurement device acquires current measurements, retrieves past measurements from storage, compares them using the fluctuation detection unit, and notifies the user of detected fluctuations. This eliminates the need for users to manually perform comparisons, reducing operational complexity while maintaining detection accuracy.
Solution Approach 2:
The control unit acts as an intermediary that manages the entire process of data acquisition, storage, retrieval, comparison, and notification. It mediates between the blood pressure measurement function and the user, handling all complex operations internally and presenting simplified results to the user, thus reducing perceived complexity while maintaining precision.
