Alarm Clock Interface Vital Sign Sensor for Stress Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stress-measuring systems are obtrusive, require active user participation, and lack mobility, making it difficult to accurately and unobtrusively monitor vital signs for early burnout detection.
Innovation Solution
A stress-measuring system integrated into an alarm clock that measures vital signs, such as heart rate, through a sensor embedded in the interface, allowing for unobtrusive and mobile monitoring without additional user action, using photoplethysmography, electrocardiography, or remote photoplethysmography, with a processing unit to determine stress levels and provide feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a stress-measuring system uses dedicated measurement devices, then measurement precision is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The alarm clock interface is designed to serve multiple functions: it acts as both a user interaction interface for switching off the alarm and as a sensor for measuring vital signs. This multi-functionality eliminates the need for separate measurement devices, reducing device complexity while maintaining measurement precision through integrated photoplethysmography or electrocardiography sensors.
2Measurement precision
If a stress-measuring system requires active user participation, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system automatically measures vital signs during the user's natural interaction with the alarm clock interface without requiring additional user actions. The sensor captures photoplethysmography or electrocardiography signals passively while the user presses the interface to switch off the alarm, eliminating the need for active participation in the measurement process while maintaining measurement precision.
3Ease of operation
If a stress-measuring system uses portable devices, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The patent combines a portable alarm clock device with integrated vital sign sensors (photoplethysmography or electrocardiography) to create a mobile stress-measuring system. This merging maintains measurement precision by incorporating medical-grade sensing capabilities into a portable consumer device, eliminating the trade-off between mobility and accuracy.
