Aerosol Nebulizer Control for Real-Time Sensor Data Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol nebulizer systems face challenges in providing real-time therapy-related feedback due to limited data transmission rates in low-capacity wireless connections, which are exacerbated by the increasing amount of sensor data generated by multiple sensor units, hindering effective patient training and support during inhalation therapy.
Innovation Solution
A control device with a sensor data control unit that prioritizes and selects a subset of sensor data for transmission during inhalation, using algorithms and thresholds to ensure real-time feedback, while temporarily storing non-essential data for later transfer, thereby optimizing data transmission and maintaining real-time functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all sensor data from multiple sensor units are transmitted wirelessly during inhalation therapy, then the completeness of therapy data is improved, but the data transmission rate is exceeded and real-time feedback capability is lost
Solution Approach 1:
The patent segments sensor data into priority levels (first priority for real-time feedback, second priority for later transfer). The control device selectively transmits only high-priority sensor data during inhalation therapy to maintain real-time feedback capability, while storing lower-priority data for subsequent transfer when transmission capacity is available.
Solution Approach 2:
The patent dynamically adjusts data transmission parameters based on operational state. During inhalation therapy, the system changes transmission behavior to prioritize real-time data, modifying which sensor data parameters are transmitted and at what frequency, thereby adapting to the limited wireless communication capacity.
2Loss of information
If a high-capacity wireless connection is used to transmit all sensor data, then real-time feedback capability is improved, but energy consumption increases
Solution Approach 1:
The patent applies partial action by transmitting only the necessary subset of sensor data (first priority data) required for real-time feedback during inhalation therapy, rather than transmitting all sensor data. This reduces the data transmission volume and associated energy consumption while maintaining the essential real-time feedback capability.
3Speed
If sensor data is prioritized and selectively transmitted during inhalation, then real-time feedback is maintained, but data completeness is reduced
Solution Approach 1:
The patent performs preliminary action by storing second priority sensor data in the memory unit during inhalation therapy for later transfer. This ensures that while real-time feedback uses only essential data, the complete dataset is preserved and can be transmitted subsequently when wireless communication capacity is available, thereby maintaining overall data completeness.
