Packaging Assembly With Device Detection for Dosing Reminders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients with chronic diseases often struggle to keep track of scheduled dosing times for refrigerated medicaments, which are stored alongside food and other items in a household fridge, making it difficult to remember when to administer doses.
Innovation Solution
A packaging assembly that stores multiple injection devices, including pen-injectors and auto-injectors, with integrated electronics to provide audio and visual reminders at scheduled dosing times, and includes a door open sensor to conditionally activate reminders, ensuring discreet and intuitive use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the packaging assembly provides audio and visual reminders at scheduled dosing times, then the patient can be alerted to administer medicament on time, but the reminder may be accidentally activated when the fridge door is opened
Solution Approach 1:
The door open sensor provides feedback about the fridge door state to the controller. The controller uses this feedback to conditionally activate reminders only when the door is closed, preventing false alarms while ensuring timely notifications when the door is opened
Solution Approach 2:
The reminder activation is made dynamic by conditioning it on the real-time state of the door open sensor. The system transitions between different operational states (reminder active/inactive) based on the door state, allowing adaptive behavior
2Ease of operation
If the packaging assembly includes integrated electronics for reminders, then dosing time tracking is improved, but the device complexity increases
Solution Approach 1:
The packaging assembly serves multiple functions: it stores injection devices, tracks dosing schedules via the controller, provides audio/visual reminders, and monitors door state via the sensor. This multi-functionality consolidates what would otherwise require separate devices into one integrated system
Solution Approach 2:
The controller integrates the door open sensor, reminder generation, and display functions into a single control unit. This merging reduces the number of separate components and simplifies the overall system architecture while maintaining ease of operation
