Inhalation Device Data Transmission Limiting Battery Usage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drug delivery devices, particularly inhalation devices, face challenges in reducing battery usage while maintaining effective data transmission for adherence and compliance tracking, due to limited power sources and frequent data transfer requirements.
Innovation Solution
A system that limits the number of data transmissions from inhalation devices to external devices, utilizing a cloud-based system and mobile applications to manage data synchronization, ensuring that only the most recent data is transmitted, thereby reducing battery consumption and extending device life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the inhalation device frequently transmits inhalation data to external devices for adherence tracking, then the adherence and compliance tracking accuracy is improved, but the battery power consumption increases
Solution Approach 1:
The system performs preliminary actions by storing inhalation data locally in the inhalation device's memory and by having external devices check for new data before requesting transmission. This prevents unnecessary transmission cycles and reduces battery power consumption while maintaining accurate adherence tracking through local data storage and selective synchronization.
Solution Approach 2:
The system implements feedback mechanisms where external devices transmit feedback signals to the inhalation device indicating whether new data is available or if the device should enter low-power mode. This feedback loop optimizes the transmission frequency based on actual data changes, reducing unnecessary transmissions and conserving battery power while maintaining tracking accuracy.
2Adaptability or versatility
If the inhalation device transmits data to multiple external devices simultaneously, then the data availability for different users is improved, but the battery usage increases
Solution Approach 1:
The system segments the data transmission process by introducing a cloud-based intermediary that receives data from the inhalation device and distributes it to multiple external devices. This segmentation allows the inhalation device to transmit data only once to the cloud, which then handles distribution to multiple users, reducing battery usage while maintaining data availability for all users.
Solution Approach 2:
The cloud-based system acts as an intermediary between the inhalation device and multiple external devices. Instead of the inhalation device directly communicating with multiple external devices (which would increase battery consumption), all communications go through the cloud intermediary, which consolidates data requests and reduces the total number of transmissions from the inhalation device.
3Weight of moving object
If the inhalation device uses a portable power source like a small battery, then the device portability is improved, but the available power capacity is limited
Solution Approach 1:
The system employs periodic action by having the inhalation device enter low-power sleep modes between use periods and only activating sensors and communication components when data transmission is actually needed. This periodic operation pattern allows the device to use a small portable battery while maintaining sufficient operational life, as the device consumes power only during brief transmission intervals rather than continuously.

AI summary
A system may limit the number of times an inhalation device transmits inhalation data to a single time to reduce the battery usage of the inhalation device. The system may include an inhalation device that has medicament and an electronics module. The system may limit the number of times the inhalation device transmits new inhalation data to any mobile device to a single time by causing the server to receive the new inhalation data from one of the mobile devices and causing the server to transmit the new inhalation data to other of the mobile devices prior to the other mobile devices transmitting a request for the new inhalation data to the inhalation device. The inhalation device may include a Quick Response (QR) code, and a mobile application may determine at least one of a medication type or a number of doses of the inhalation device from the QR code.
