Sensor-Equipped Pill Case for Context-Aware Medication Reminders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medication reminder systems do not effectively integrate reminders with eating schedules, locations, or movements, making it difficult for dialysis patients to take their medication at appropriate times.
Innovation Solution
A pill case and medication reminder system that includes sensors to detect medication levels, a global positioning system for location awareness, and an accelerometer to sense movement, generating reminders based on eating activities, time of day, and proximity to pharmacies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If medication reminder systems use simple time-based alerts, then the system is easy to operate, but it cannot correlate reminders with eating schedules and activities
Solution Approach 1:
The patent combines multiple functions (medication reminder, activity tracking, location monitoring, and communication) into a single integrated device. The pill bottle incorporates sensors, transmitters, and processors that work together with mobile devices to provide context-aware reminders based on eating schedules, location, and activity data, resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The system serves multiple functions: it monitors medication intake, tracks eating schedules, monitors physical activity, provides location-based reminders, and enables two-way communication between patient and healthcare provider. This multi-functionality allows the system to adapt to various patient needs while maintaining a unified device architecture.
2Measurement precision
If the pill case includes multiple sensors and tracking technologies, then reminder accuracy improves, but the device becomes more complex
Solution Approach 1:
The system employs a nested architecture where the pill bottle contains sensors and transmitters that communicate with a mobile device, which in turn connects to healthcare provider systems. This nested structure allows multiple tracking technologies (sensors, GPS, accelerometers) to be integrated without overwhelming the user interface, maintaining ease of use while improving measurement precision.
3Reliability
If the system uses two-way communication capabilities, then patient compliance monitoring improves, but energy consumption increases
Solution Approach 1:
The system uses periodic communication rather than continuous transmission. The pill bottle transmitter communicates with the mobile device at scheduled intervals or when specific events occur (medication taken, bottle opened), and the mobile device communicates with the healthcare provider periodically. This periodic action maintains reliable compliance monitoring while significantly reducing energy consumption compared to continuous communication.
Data Source
AI summary
A pill case and medication reminder system is provided. A pill case and a reminder system are in data transfer communication with one another. The system can also include a global positioning system, an accelerometer, or both. A pill case compartment is configured to hold a medication. The pill case has a sensor or sensor array configured to detect the amount of medication in the pill case. A pill case processor is configured to generate a data signal pertaining to the amount of medication in the pill case. The system can generate medication reminders, for example, pertaining to refilling a subscription or taking medication with food. The pill case can include or connect to a phone case for a smartphone, or can be integrated into a smartwatch.
