Solution Overview

Problem

Current systems for filling and dispensing pharmaceutical prescriptions lack automation, leading to inefficiencies and safety concerns in handling and administration of medications, particularly in selecting and loading unit doses into compartments for patient-specific prescriptions.

Innovation Solution

An automated apparatus with a telescopic manipulator and barcode reading system that selects and picks up unit doses from a matrix, allowing for direct loading into compartments of a cart, ensuring safe and efficient dispensing, and managed by dedicated software for inventory control and urgent needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automated manipulator systems are introduced to pick and place unit doses, then productivity and safety are improved, but device complexity increases

Engineering Contradiction:
Improvedispensing speedVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The automated dispensing system is divided into separate functional modules: a manipulator unit for picking unit doses, a reader unit for barcode scanning, and a cart with compartments for storage. This modular segmentation allows each component to perform its specific function efficiently while reducing the overall system complexity through independent, standardized interfaces between modules.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The manipulator unit is designed with universal functionality to handle various types of unit doses (blister packs, sachets, bottles) through a standardized picking mechanism. The reader unit can scan different barcode types on different packaging formats, and the cart compartments can accommodate multiple medication types, making the entire system versatile and adaptable to different dispensing needs without requiring separate specialized equipment for each medication type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If barcode reading systems are integrated for unit dose identification, then measurement precision and reliability are improved, but device complexity increases

Engineering Contradiction:
Improveidentification accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The barcode reading functionality is merged directly into the manipulator unit, combining the mechanical picking function with the optical identification function in a single integrated component. This merging eliminates the need for separate identification stations, reduces the number of components, and streamlines the workflow by performing both picking and identification in one automated action, thereby improving efficiency without proportionally increasing system complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Loss of time

If direct loading into cart compartments is implemented, then loss of time is reduced, but ease of operation may be affected

Engineering Contradiction:
Improvepreparation timeVSAvoidoperational simplicity
Core Design Contradiction:
Loss of timeVSEase of operation

Solution Approach 1:

The system is designed to be self-sufficient by automatically performing the complete sequence of operations: the manipulator picks unit doses, the reader verifies identification, the software determines correct placement, and the system loads doses directly into the appropriate cart compartments without requiring manual intervention. This self-service capability eliminates time-consuming manual steps while the intuitive software interface and automated decision-making maintain operational simplicity by removing complex manual decision-making from the nurse's workflow.

Inventive Principle:
Principle #25Self-service
