Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients with chronic diseases face challenges in adhering to their prescribed medication regimens due to difficulties in tracking dosing schedules, especially for medicaments requiring specific storage and administration temperatures, and varying dosing intervals, which can lead to non-adherence and incorrect use of injection devices.
Innovation Solution
A user device and system that scans injection devices to determine the threshold time for transitioning from storage to operational temperature, alerting users and providing reminders, and integrating with storage devices and sharps bins to track usage and adherence, using RFID sensors and wireless communication for accurate temperature monitoring and medication management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the injection device is stored in a refrigerator at low temperature, then the medicament stability is improved, but the device requires additional warming time before use
Solution Approach 1:
The system performs preliminary actions by calculating the required warming time in advance based on the storage temperature and ambient temperature, and notifies the user before the warming period expires. This allows the user to plan accordingly and ensures the device is ready for use at the appropriate time, resolving the contradiction between maintaining medicament stability through refrigeration and minimizing warming time loss.
2Adaptability or versatility
If the user is provided with multiple types of injection devices for different dosages, then the treatment flexibility is improved, but the complexity of tracking and using the correct device increases
Solution Approach 1:
The system implements feedback by scanning the injection device, identifying its type and dosage, and providing real-time notifications to the user about which device should be used and when. The system tracks usage patterns and reminds users of upcoming doses, thereby simplifying the management of multiple device types while maintaining treatment flexibility.
Solution Approach 2:
The injection device itself performs self-identification through scanning, automatically providing information about its type, dosage, and usage requirements to the system. This eliminates the need for manual tracking by the user and reduces the complexity of managing multiple device types while preserving adaptability.
3Ease of operation
If the dosing interval is extended to reduce frequency of administration, then the patient convenience is improved, but the risk of non-adherence increases
Solution Approach 1:
The system provides continuous feedback through automated reminders and notifications that alert users when their next dose is due, even with extended dosing intervals. This maintains high adherence reliability by ensuring users are aware of their dosing schedule without requiring frequent administrative actions, thus preserving patient convenience while mitigating non-adherence risks.
