Medicament Package Motion Sensor Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medicament delivery device package assemblies face challenges in managing power consumption and tracking dosing schedules, especially for devices stored in refrigerators or used in emergency situations, where high power consumption and lack of clear indication or communication hinder efficient usage and location identification.
Innovation Solution
Incorporating a motion sensor to detect the opening of a storage unit door, which triggers indicators and communication units to provide user notifications and regulate power consumption, along with a reservoir sensor to track medicament usage and a temperature sensor to monitor storage conditions, within a package assembly designed for multiple medicament delivery devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a communication unit based on cellular wireless communication technology is added to provide user notifications and caregiver communication, then the functionality and user guidance are improved, but the power consumption increases significantly
Solution Approach 1:
The communication unit operates periodically rather than continuously, being activated only when the motion sensor detects door opening events. This allows the device to maintain communication functionality for user notifications while dramatically reducing overall power consumption by keeping the high-power communication module dormant during storage periods.
Solution Approach 2:
The motion sensor automatically triggers the communication unit based on detected door opening events without requiring manual user activation. The system self-regulates its power consumption by activating communication functions only when storage conditions change, eliminating the need for continuous user interaction or monitoring.
2Loss of information
If indicators and communication units are continuously active to provide clear indications and tracking, then user guidance is improved, but power consumption increases
Solution Approach 1:
The indicator and communication units are activated periodically only when the motion sensor detects door opening events, rather than operating continuously. This ensures dosing schedule information is communicated to users when they access the storage unit, while minimizing power consumption during extended storage periods when the device remains in the refrigerator.
Solution Approach 2:
The motion sensor provides feedback about storage unit access events, which triggers the indicator and communication unit to activate and provide dosing information. This feedback-based activation ensures information is provided exactly when users need it (upon accessing the storage unit) rather than continuously, optimizing both information delivery and power efficiency.
3Ease of operation
If multiple sensors and communication units are added to the package assembly, then the functionality and user guidance are improved, but the device complexity increases
Solution Approach 1:
Multiple functional components (motion sensor, indicator, communication unit, temperature sensor) are integrated into a single package assembly housing. This merging approach consolidates what could be separate complex devices into one unified system, reducing overall system complexity while maintaining advanced functionality for automated dosing tracking and notification.
Solution Approach 2:
The package assembly is designed as a multi-functional system where a single device performs multiple roles: storage container, temperature monitoring, motion detection, user notification, and communication with caregivers. This universal design eliminates the need for separate devices for each function, reducing overall complexity while providing comprehensive automated dosing management.
