Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable physiological measurement devices are limited by the number of measurements they can perform, ergonomics, and ease of use, which hinders their effectiveness in remote patient monitoring (RPM) and self-measurement applications.
Innovation Solution
A portable physiological measurement device with an elongated housing design, featuring physiological end sensors at each end and a finger sensor in between, allowing for easy gripping and operation with one or two hands, and enabling multiple physiological measurements without interfering with the user's grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple physiological sensors are integrated into a single device, then the measurement capability is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple physiological sensors (thermometer, stethoscope, oximeter, ECG electrodes, ultrasound transducer) into a single integrated device with a unified housing. This merging approach allows the device to perform multiple measurements while maintaining a compact form factor that does not significantly increase complexity for the user.
Solution Approach 2:
The device is designed as a universal measurement tool that can perform various physiological measurements through different sensors. The housing accommodates multiple sensor types, each accessible at different locations, allowing one device to replace multiple specialized instruments.
2Ease of operation
If the device is made compact for easy handling, then the ease of operation is improved, but the number of measurements is limited
Solution Approach 1:
The patent arranges sensors in different spatial dimensions and locations on the housing - end sensors at opposite ends, finger sensors on the surface, and electrodes on contact areas. This multi-dimensional arrangement allows multiple measurements to be taken simultaneously or sequentially without increasing the device's compact footprint, maintaining ease of handling while expanding measurement capability.
3Measurement precision
If sensors are positioned for optimal measurement, then the measurement precision is improved, but the ergonomics deteriorate
Solution Approach 1:
The patent positions different sensor types at specific locations on the housing optimized for their function: end sensors for contact with body extremities, finger sensors for finger placement, and electrodes on flat surfaces for skin contact. Each sensor location is optimized for its specific measurement type while the overall housing geometry maintains ergonomic gripability.
