Automated Spooling System for Medication Cartridge Loading Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients, especially senior citizens and disabled individuals, face challenges in managing multiple prescriptions and adhering to medication regimens, leading to non-compliance issues such as missed doses, incorrect administration times, and dangerous interactions, resulting in significant healthcare costs and adverse outcomes.
Innovation Solution
A method for preparing medication cartridges that automatically wind a strip of medication pouches around a spool within a dispensing cartridge, collecting data on each pouch, and validating the cartridge, ensuring accurate and timely dispensing of medications, with features like secure locking and communication with a cloud system for adherence tracking and alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a strip of medication pouches is manually loaded into a dispensing cartridge, then the loading process is simple and requires minimal equipment, but the accuracy and efficiency of loading are reduced leading to potential errors and time consumption
Solution Approach 1:
The system performs preliminary actions by automatically positioning and aligning the medication strip within the cartridge before final insertion. The spool mechanism pre-loads the strip in a controlled manner, ensuring proper orientation and placement of each pouch before the cartridge is sealed and ready for dispensing.
Solution Approach 2:
The loading system utilizes self-service mechanisms where the spool automatically winds the medication strip onto itself under controlled conditions. The system self-regulates the loading process through integrated sensors and motors that monitor strip position, tension, and alignment without requiring external manual intervention for each step.
2Quantity of substance
If medication strips are wound tightly around the spool to maximize cartridge capacity, then the quantity of medication that can be stored increases, but the risk of damage to pouches and difficulty in dispensing increases
Solution Approach 1:
The system dynamically adjusts winding parameters such as tension force, winding speed, and spool rotation rate based on real-time feedback from sensors. The control system modifies these parameters to maintain optimal tension that secures pouches firmly while preventing excessive force that could damage the medication packaging or make dispensing difficult.
Solution Approach 2:
The loading system incorporates feedback mechanisms through sensors that monitor pouch position, strip tension, and spool rotation during the winding process. This feedback is used by the control system to automatically adjust winding parameters, ensuring that pouches are wound securely without excessive tension that could compromise their integrity or create dispensing problems.
3Productivity
If the loading process is fully automated to improve accuracy and efficiency, then loading precision and speed increase, but the device complexity and cost increase
Solution Approach 1:
The automated loading system is designed with multi-functional components that perform multiple operations. The spool mechanism not only winds the medication strip but also serves as a tensioning device, positioning mechanism, and storage element. The control system integrates loading, alignment, and verification functions into a single automated sequence, reducing the need for separate dedicated components for each function.
Solution Approach 2:
The system merges several loading operations into a single integrated process. The spool mechanism combines winding, tensioning, and positioning functions in one component. The automated system combines strip feeding, pouch alignment, and cartridge insertion into a unified loading sequence, reducing overall system complexity while maintaining high productivity.

AI summary
The present specification describes a system for automatically preparing medication cartridges for use in a pharmaceutical dispensing system. The system includes a spooler device that winds a strip of medicine pouches around a cylinder in a cartridge frame. When the cartridge has been loaded with the medication strip, the system validates that there is a match between the information on the cartridge cover and the mediation pouches.
