Smart Cap for Medication Pen Dose Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of automated and reliable methods for tracking and communicating medication doses administered via injection pens, particularly for chronic conditions like diabetes, leading to potential missed or incorrect doses, which can have serious health consequences.
Innovation Solution
A smart cap device that can be attached to medication pens to track delivery events, including dose size and time, and transmit this data to a companion device, such as a smartphone, using sensors like audio transducers and tactile sensors to detect mechanical feedback, and a data processing unit for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual tracking of medication doses is used, then device complexity is low, but reliability of dose tracking deteriorates due to potential missed or incorrect doses
Solution Approach 1:
The medication delivery pen is equipped with sensors and data processing capabilities that enable it to automatically detect and record delivery events, dose sizes, and timestamps without requiring user intervention. The device self-monitors its own operation and transmits data to companion devices, eliminating the need for manual tracking while maintaining simplicity of use.
Solution Approach 2:
The system implements automated feedback mechanisms where the pen device detects delivery events through sensors, processes the data locally, and transmits it to companion devices for verification and analysis. This closed-loop feedback system ensures accurate tracking and provides immediate confirmation of dose administration.
2Measurement precision
If automated tracking with sensors is implemented, then measurement precision of delivery events is improved, but device complexity increases due to additional components
Solution Approach 1:
The pen device integrates multiple functions into a single platform: it maintains its primary medication delivery capability while incorporating sensors for detection, data processing unit for analysis, and communication module for data transmission. This multi-functional integration achieves precise measurement without requiring separate dedicated devices for each function.
Solution Approach 2:
The system merges the medication delivery mechanism with tracking and communication capabilities into a unified device. The sensors, data processing unit, and companion device communication are integrated with the existing pen structure, combining therapeutic and monitoring functions in one device to minimize overall system complexity.
3Loss of information
If data transmission to companion device is added, then loss of information about medication adherence is reduced, but device complexity and energy consumption increase
Solution Approach 1:
The device performs preliminary data processing and filtering before transmission, preparing data packets in advance and only transmitting when necessary or when communication opportunities arise. This reduces the frequency and volume of transmissions, thereby lowering energy consumption while ensuring that critical adherence information is captured and communicated.
