Biometric Monitoring Device Heart Rate Gesture Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biometric monitoring devices require cumbersome user interactions for heart rate measurement, such as multiple gestures or continuous activation, which is energy inefficient and inconvenient, especially for portable devices with multiple functions and miniaturized sizes.
Innovation Solution
A biometric monitoring device with a heart rate monitoring function activated by a single user-gesture, utilizing a heart rate sensor, activator, processor, and memory connected for automatic data collection and feedback without additional user input, allowing energy conservation and simplified operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous or regular intermittent activation of heart rate sensor is used, then heart rate monitoring reliability is improved, but energy consumption increases
Solution Approach 1:
The system uses periodic activation of the heart rate sensor based on user gestures rather than continuous activation. The sensor is activated at specific intervals triggered by user interaction (wrist lift gesture), which reduces energy consumption while still providing reliable monitoring when needed.
Solution Approach 2:
The system automatically activates and deactivates the heart rate sensor based on detected user gestures without requiring manual user input to start or stop monitoring. The device serves itself by using motion sensors to detect wrist lifts and automatically initiating heart rate measurement, then stopping after a predetermined time period.
2Adaptability or versatility
If multiple user gestures are required to activate heart rate sensor and provide feedback, then device functionality is improved, but ease of operation deteriorates
Solution Approach 1:
The system combines multiple functions (heart rate sensor activation, data collection, and feedback provision) into a single user gesture. When the user performs one wrist lift gesture, the system activates the heart rate sensor, collects data for a predetermined period, and automatically provides feedback, eliminating the need for separate gestures for each function.
Solution Approach 2:
The single user gesture triggers multiple functions simultaneously - activating the heart rate sensor, initiating data collection, and preparing feedback mechanisms. This multi-functional response to a single input simplifies operation while maintaining comprehensive device functionality.
3Measurement precision
If heart rate sensor is activated frequently, then measurement precision is improved, but battery life deteriorates
Solution Approach 1:
The system activates the heart rate sensor periodically based on user gestures rather than continuously, reducing overall activation frequency while maintaining measurement precision during active periods. The sensor collects data for a predetermined time period after each gesture, ensuring adequate measurement quality without excessive battery drain.
Solution Approach 2:
The system activates the heart rate sensor for a predetermined time period that may be longer than the minimum needed for a single measurement, allowing for multiple measurements or extended monitoring in one activation cycle. This reduces the total number of activations needed, thereby extending battery life while maintaining or improving overall measurement precision.
