Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for prescription drugs due to an aging population and rising number of medications exceeds the capacity of licensed pharmacists, leading to pharmacists spending more time on administrative tasks, increasing the likelihood of prescription errors and adverse drug events, as existing visual verification methods are unreliable for visually similar medications and fail with reused bottles lacking manufacturer bar codes.
Innovation Solution
An automated system that combines bar code scanning, vision station imaging, and spectroscopy to verify pharmaceutical identities, using a conveyor system to move vials through these stations for accurate verification and approval, reducing human error and reliance on visual distinctness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If visual verification methods are used to verify pharmaceutical identities, then the verification process can be performed with simple equipment, but the reliability of verification deteriorates because many drugs are not visually distinct and visual differences are very subtle
Solution Approach 1:
The patent replaces manual visual verification with automated optical scanning systems including cameras and spectroscopy devices. The system captures images of pharmaceutical containers and uses image processing algorithms to automatically identify and verify drug identities, eliminating reliance on human visual inspection and thereby significantly improving verification reliability while maintaining manageable system complexity through automation.
Solution Approach 2:
The patent transforms the verification approach by changing from visual parameter comparison (color, shape, size) to spectral parameter analysis. By using spectroscopy to obtain spectral signatures of pharmaceutical substances and comparing these against reference databases, the system achieves high reliability in identifying visually similar drugs through their unique chemical fingerprint characteristics rather than external appearance.
2Ease of operation
If bar code scanning is used to verify pharmaceutical identities, then the verification process is simplified, but the method fails when bottles are reused and lack manufacturer bar codes
Solution Approach 1:
The patent creates a multi-functional verification system that can handle multiple types of pharmaceutical containers and identification methods. The system is designed to work with bar-coded containers by scanning and verifying manufacturer codes, while simultaneously being capable of imaging and verifying reused containers that lack bar codes through alternative identification methods such as container shape analysis, label recognition, and spectral fingerprinting, thereby achieving universal applicability across different container types.
Solution Approach 2:
The patent introduces an intermediary imaging and analysis system that bridges the gap between bar code scanning and direct pharmaceutical verification. When bar codes are present, the system scans them for quick identification. When bar codes are absent (reused bottles), the intermediary imaging system captures container characteristics and spectral data to serve as an alternative identification pathway, ensuring continuous verification capability regardless of bar code presence.
3Measurement precision
If manual verification by pharmacists is performed, then the verification accuracy can be maintained, but the time required for each prescription increases, reducing pharmacy productivity
Solution Approach 1:
The patent implements a self-verification system where the pharmaceutical verification process is performed automatically without requiring pharmacist intervention. The system autonomously captures images of dispensed medications, compares them against prescription requirements using image processing and spectral analysis, and generates verification results. This self-service capability maintains high verification accuracy through automated quality control while eliminating the time-consuming manual inspection process, thereby significantly increasing pharmacy productivity.
Solution Approach 2:
The patent replaces the manual verification process with automated optical and spectral analysis systems. Cameras capture images of pharmaceutical containers and contents, while spectroscopy devices obtain chemical fingerprints. Image processing algorithms and spectral analysis software automatically compare these data against the prescription and reference databases, substituting human visual inspection with automated computational verification that maintains accuracy while dramatically reducing verification time per prescription.
4Reliability
If multiple verification methods are combined to improve verification reliability, then the accuracy of pharmaceutical identification increases, but the device complexity and cost increase
Solution Approach 1:
The patent combines multiple verification methods including bar code scanning, digital imaging, and spectroscopy into an integrated verification system. These different verification approaches are merged into a single coordinated process where each method complements the others: bar code scanning provides quick initial identification, imaging captures visual characteristics and container features, and spectroscopy obtains chemical fingerprints. The combined approach achieves high verification reliability by cross-validating results across multiple modalities while managing system complexity through integrated hardware and software architecture.

AI summary
A system for verification of dispensed pharmaceuticals includes: a housing; a bar code scanning station mounted on the housing; a vision station mounted on the housing; a spectroscopy station mounted on the housing; an offloading station mounted on the housing; one or more conveyors mounted on the housing to convey pharmaceutical vials between the bar code scanning, vision, spectroscopy and offloading stations, and a controller associated with the bar code scanning, vision, spectroscopy and offloading stations and the conveyors to control their operations. A system of this configuration can use both vision and spectroscopy to verify the identity of the pharmaceutical in the container.
