Medication Receptacle Alignment Detection for Automated Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated dispensing systems for unit dose medications face challenges in handling and dispensing medications of varying shapes and sizes, requiring manual intervention and alignment adjustments, which can lead to inefficiencies and errors.
Innovation Solution
A mechanism that includes a processing circuitry and alignment detection system to determine the alignment state of medication receptacles, enabling automatic handling and dispensing by using optical or sensing techniques to identify alignment errors and facilitate proper alignment of unit dose blister packages within a storage and retrieval system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual intervention is used for alignment adjustments of medication receptacles, then handling flexibility is improved, but time consumption and labor intensity increase
Solution Approach 1:
The system employs optical sensors and alignment detection mechanisms that automatically detect and correct the position of medication receptacles without requiring manual intervention. The receptacles self-align through automated guidance systems, eliminating the need for human operators to physically adjust each item while maintaining handling flexibility through programmable correction algorithms.
Solution Approach 2:
Manual mechanical alignment adjustments are replaced with optical sensing systems and automated positioning mechanisms. The system uses light sensors, cameras, or other detection devices to identify misaligned receptacles and activates robotic arms or conveyor adjustments to correct positions automatically, substituting human mechanical actions with automated electromechanical systems.
2Productivity
If automated picking means is used for medication retrieval, then productivity is improved, but measurement precision of alignment state deteriorates
Solution Approach 1:
An intermediary alignment detection system is introduced between the automated picking mechanism and the medication receptacles. This intermediate layer uses high-precision optical sensors, laser scanners, or vision systems to accurately measure the position and orientation of receptacles before they are picked, providing precise feedback data that guides the automated picker while maintaining high retrieval speeds through pre-positioning.
Solution Approach 2:
The system performs preliminary alignment detection and correction of medication receptacles before the automated picking process begins. By pre-positioning and verifying the alignment of all receptacles in advance, the system ensures high measurement precision is achieved during the detection phase, allowing the subsequent automated picking to proceed rapidly without compromising accuracy.
3Extent of automation
If repackaging medications with barcodes is implemented, then automation capability is improved, but device complexity increases
Solution Approach 1:
The system merges the barcode reading function with the existing optical sensing infrastructure used for alignment detection. The same optical sensors and image processing algorithms that detect receptacle positions are also used to read and verify barcode information, combining multiple functions into a unified system rather than adding separate dedicated barcode scanning equipment, thus reducing overall system complexity.
Data Source
AI summary
A method for facilitating storage and/or retrieval of unit dose medications may include receiving an indication that a medication receptacle is positioned proximate to an alignment pin, determining a position of the alignment pin relative to an alignment guide disposed in the medication receptacle, and providing an output indicative of an alignment state of the medication receptacle based on the position determined.
