Solution Overview

Problem

Existing pharmaceutical packaging systems lack efficiency in verifying the accuracy of medication packaging and provide limited opportunities for pharmacists to identify and correct errors, leading to inefficiencies and potential breaks in the packaging process.

Innovation Solution

A pharmacy management system incorporating an electronic processor, pre-counter, and automatic packager with verification capabilities to count, package, and verify medications, utilizing barcode scanning, camera systems, and RFID technology to ensure accurate packaging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual verification of medication packaging is performed, then packaging accuracy can be maintained, but productivity decreases and time loss increases

Engineering Contradiction:

Improvepackaging accuracyVSAvoidpackaging throughput

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The packaging system performs self-verification through integrated verification units that automatically check medication packaging parameters without requiring external manual inspection, enabling the system to maintain accuracy while operating autonomously at high speed

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Manual verification processes are replaced with automated verification units that use optical sensors, cameras, and computer vision algorithms to detect and verify medication packaging, substituting human mechanical inspection with automated sensing and processing systems

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If multiple verification points are implemented, then packaging accuracy improves, but device complexity increases

Engineering Contradiction:

Improvepackaging accuracyVSAvoidsystem complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The verification system is divided into multiple independent verification units, each responsible for specific verification tasks at different stages of the packaging process, allowing complex verification functions to be modularized and managed separately

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Verification checks are performed at multiple preliminary stages before final packaging completion, allowing errors to be detected and corrected early in the process rather than requiring complex post-packaging verification systems

Inventive Principle:

Principle #10Preliminary action

3Productivity

If automated verification is implemented, then productivity increases, but measurement precision requirements increase

Engineering Contradiction:

Improvepackaging throughputVSAvoidverification accuracy

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

Image processing algorithms and computer vision systems serve as intermediaries between the physical packaging and the verification system, enhancing the precision of automated detection by converting physical packaging parameters into analyzable digital data that can be accurately measured and verified

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Automatic packager for pharmaceuticals and method of operating the same. The method includes receiving a prescription to be filled by a pharmacy management system and identifying one or more bulk containers that contain medications to fill the prescription. The method also includes counting, using a pre-counter, medications from the one or more bulk containers to fill the prescription and depositing the counted medications in one or more cartridges. The method also includes placing the one or more cartridges including the counted medications at an automatic packager and dispensing the medications in the one or more cartridges. The method also includes packaging medications dispensed from the one or more cartridges into packages and verifying whether the medications are correctly packaged.
