Blister Pack Sensor for Pill Removal Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pill reminder systems are inadequate as they rely solely on timers and do not monitor or record pill removal from blister packs, making it difficult for users, especially the elderly, to remember to take medications on time.
Innovation Solution
An apparatus attached to the blister pack that uses sensors, such as cameras, to detect pill removal and communicate with a remote device to issue reminders via output devices like speakers or displays, ensuring timely medication intake based on prescription schedules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If timer-based reminder systems are used, then the device complexity is low, but the reliability of medication adherence monitoring is insufficient
Solution Approach 1:
The patent replaces mechanical timer-based reminder systems with an optical sensing system using cameras and image processing to detect pill removal. This substitution enables reliable monitoring of actual medication adherence by detecting whether pills have been taken, rather than merely providing time-based reminders.
Solution Approach 2:
The system automatically detects pill removal through camera-based monitoring and self-issues reminders without requiring user intervention to set timers or track medication. The apparatus autonomously monitors the blister pack and communicates adherence status, enabling the system to serve itself in monitoring medication intake.
2Measurement precision
If camera-based pill removal detection is implemented, then the measurement precision of pill intake monitoring is improved, but the device complexity increases
Solution Approach 1:
The system uses camera-based optical copying to create visual records of the blister pack state and pill removal events. Instead of complex mechanical sensors, the apparatus captures images that serve as copies of the physical state, enabling precise detection of pill intake through image analysis.
Solution Approach 2:
The camera component serves multiple functions: detecting pill removal, verifying blister pack integrity, and providing visual documentation of medication status. This multi-functionality reduces the need for separate specialized sensors, thereby managing device complexity while maintaining high measurement precision.
3Loss of information
If remote communication capabilities are added, then the loss of information about medication adherence is reduced, but the device complexity increases
Solution Approach 1:
The patent introduces a remote communication device as an intermediary between the local monitoring apparatus and the user or healthcare provider. This intermediary transmits adherence information wirelessly, reducing information loss by enabling remote access to medication tracking data without requiring complex direct integration between all system components.

AI summary
The invention is related to an apparatus that includes: a housing attachable to a blister pack, at least one sensor attached to the housing and capable of sensing removal of a pill from an attached blister pack and a controller. The controller is configured to: determine a timing parameter for taking a pill, receive from the at least one sensor a signal, determine based on the signal if a pill was removed from the blister pack, and if a pill was not removed from the blister pack within a time period based on the timing parameter issue to an output unit a reminder signal for taking the pill.
