Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infections pose a significant threat to human health, often requiring early medical intervention for optimal health outcomes, and existing technologies lack effective methods for rapid and continuous detection outside clinical settings.
Innovation Solution
Ear-wearable devices equipped with sensors and a control circuit analyze physiological parameters, such as heart rate, respiration, and temperature, to detect the risk of infections, including bacterial, viral, and fungal infections, by continuously monitoring and comparing data against baseline patterns and thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If continuous monitoring of physiological parameters is implemented, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The device divides the monitoring system into separate functional modules: temperature sensor, motion sensor, light sensor, and electroacoustic transducer. Each sensor independently measures specific physiological parameters, and the control circuit processes data from each module separately before integrating results for infection risk assessment.
Solution Approach 2:
The ear-wearable device integrates multiple sensing functions (temperature monitoring, motion detection, light detection, and acoustic transmission) into a single universal platform. The control circuit universally processes all sensor inputs and applies the same infection risk assessment algorithm across different physiological parameters.
2Reliability
If multiple sensors are integrated for comprehensive monitoring, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent combines temperature sensor, motion sensor, light sensor, and electroacoustic transducer into a single integrated ear-wearable device. All sensors and the control circuit are housed together, allowing users to operate one unified device rather than managing multiple separate monitoring tools.
Solution Approach 2:
The control circuit automatically processes sensor data, compares readings against baseline patterns, and generates infection risk assessments without requiring user intervention. The device self-calibrates and performs continuous monitoring autonomously, minimizing the operational burden on users.
