Solution Overview
Problem
Existing aerosol delivery devices lack the capability to effectively determine the user's state based on biometric information, which is crucial for providing personalized and safe aerosol administration.
Innovation Solution
An electronic device equipped with biometric sensors, such as those in the mouthpiece and housing, measures biometric information like exhalation substances, heart rate, and blood oxygen saturation, and a server processes this data to determine the user's state, transmitting it to a user terminal for notification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If biometric sensors are integrated into the aerosol delivery device, then the capability to determine user state is improved, but the device complexity increases
Solution Approach 1:
The aerosol delivery device is designed to perform multiple functions: it delivers aerosol therapy while simultaneously monitoring biometric parameters (heart rate, respiratory rate, oxygen saturation) and determining user state. This multi-functionality approach allows the device to provide both treatment and monitoring capabilities without requiring separate dedicated systems, thereby improving adaptability while managing complexity through integration.
Solution Approach 2:
The patent combines the aerosol delivery mechanism with biometric sensing and processing systems into a single integrated device. The sensors for measuring heart rate, respiratory rate, and oxygen saturation are incorporated directly into the device structure, and the processing unit that determines user state is merged with the delivery system. This merging of functions resolves the contradiction by achieving multi-functionality while minimizing the increase in overall device complexity through unified design.
2Measurement precision
If multiple biometric sensors are used to measure comprehensive user state, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The device incorporates multiple biometric sensors (heart rate sensor, respiratory rate sensor, oxygen saturation sensor) that can simultaneously measure different physiological parameters. This multi-functional sensing capability enables comprehensive monitoring of user state with high measurement precision, as each sensor contributes specific data that complements the others, providing a complete picture of the user's condition without requiring overly complex individual sensor systems.
Solution Approach 2:
The biometric monitoring function is segmented into separate sensor modules, each dedicated to measuring specific parameters (heart rate, respiratory rate, oxygen saturation). This segmentation allows for modular design where each sensor can be optimized for its specific function, improving measurement precision for each parameter while keeping the overall device complexity manageable through standardized, interchangeable sensor components that can be independently selected and combined.
3Reliability
If real-time biometric monitoring is implemented, then the reliability of aerosol delivery is improved, but the use of energy increases
Solution Approach 1:
The biometric monitoring system operates continuously to provide real-time data on user state, ensuring that the aerosol delivery can be reliably adjusted based on ongoing physiological changes. The sensors continuously measure heart rate, respiratory rate, and oxygen saturation, and the processing unit continuously evaluates this data to determine user state. This continuous monitoring improves reliability by ensuring the system responds to changing conditions, while energy consumption is managed through efficient sensor operation and selective data processing rather than constant high-power operation.
Solution Approach 2:
The system implements feedback control where biometric data is continuously collected, processed, and used to adjust aerosol delivery parameters in real-time. The processing unit analyzes sensor data and provides feedback signals to control the aerosol delivery mechanism, ensuring reliable therapy delivery adapted to the user's changing physiological state. This feedback mechanism improves reliability by enabling dynamic adjustment, while energy efficiency is achieved through intelligent feedback loops that activate processing and adjustment only when necessary based on the monitoring data, rather than continuous full-power operation.
