Eyeglasses with Integrated Heart Rate Sensor and Flexible Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyeglasses with heart rate monitoring systems are cumbersome and impractical due to non-integrated sensors that require separate accessories, leading to inaccurate and unreliable measurements, especially during physical activity, and limit personalization options.
Innovation Solution
The eyeglasses integrate a compact heart rate monitoring system with an adjustable, elastically flexible support element for the sensor, securely attaching it to the anatomical area, ensuring accurate and repeatable measurements, and allowing for easy lens replacement and personalization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the sensor is positioned to accurately measure heart rate, then measurement precision is improved, but the sensor moves during physical activity causing measurement errors
Solution Approach 1:
The temple piece is designed with flexible portions that allow dynamic adjustment and movement accommodation. The flexible portion enables the sensor to maintain contact with the anatomical area despite head movements and physical activity, resolving the contradiction between initial positioning accuracy and sustained measurement reliability during dynamic conditions.
2Reliability
If the measuring system is integrated into all functional parts of the eyeglasses, then measurement capability is ensured, but personalization and aesthetic customization are limited
Solution Approach 1:
The measuring system is segmented and integrated only into the frame portion of the eyeglasses, specifically in the temple piece, while the lenses remain separate and interchangeable. This segmentation allows the measurement system to maintain functionality while enabling independent lens replacement for aesthetic and technical customization, resolving the contradiction between system reliability and personalization flexibility.
3Ease of manufacture
If separate accessories are used for the measuring system, then functional components can be distributed, but the system becomes cumbersome and impractical
Solution Approach 1:
The measuring system components (sensor, microcontroller, display) are merged and integrated into the frame structure of the eyeglasses, specifically within the temple piece. This consolidation eliminates the need for separate accessories and external mounting devices, resolving the contradiction by providing manufacturing flexibility while significantly improving wearer comfort and practicality through a unified, compact design.
