Parallel Guiding Ducts for High-Frequency Drug Portion Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing system for packaging dosed quantities of solid drug portions is limited by the longest drop time of drug portions in the fall duct, restricting the filling frequency and unable to meet the increasing demand for more packages per unit time.
Innovation Solution
A system with multiple dosing stations and guiding ducts, where guiding ducts and collecting containers move continuously along dosing stations, allowing simultaneous collection of multiple prescriptions, and using conveyors to maintain constant speed and alignment, enabling increased filling frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single fall duct is used to transfer drug portions from supply containers to packaging, then the system structure is simple, but the filling frequency is limited by the longest drop time
Solution Approach 1:
The single fall duct is divided into multiple parallel fall ducts, each capable of independently transferring drug portions. This segmentation allows multiple prescriptions to be filled simultaneously, increasing filling frequency while maintaining manageable structural complexity through modular design
Solution Approach 2:
The system transitions from a single vertical fall duct to multiple fall ducts arranged in parallel, utilizing horizontal spatial dimension to enable concurrent operations. This dimensional expansion allows simultaneous filling of multiple packages without proportionally increasing system height or complexity
2Adaptability or versatility
If the fall duct length is increased to accommodate more supply containers, then more drug types can be dosed, but the drop time increases and limits filling frequency
Solution Approach 1:
Multiple shorter fall ducts are used instead of one long fall duct. Each fall duct handles a subset of drug types, allowing parallel processing of different prescriptions. This reduces the maximum drop time for any single duct while maintaining the ability to dose multiple drug types through the segmented architecture
Solution Approach 2:
The system dynamically assigns different fall ducts to different prescriptions based on the required drug types. By flexibly routing different drug combinations through different parallel ducts, the system optimizes drop times for each prescription while maintaining versatility across all possible drug combinations

Function Achieved in This Case
This approach significantly increases the filling frequency of dosed drug portions by allowing parallel collection and packaging of multiple prescriptions, enhancing efficiency and capacity while maintaining the reliability and preservation of the drug portions.
Implementation Method 1
each guiding duct is adapted to receive drug portions dispensed from at least one of the dosing stations when the guiding duct is positioned at the at least one dosing station, and to guide the received drug portions to an passage opening of the guiding duct

AI summary
A system for packaging dosed quantities of solid drug portions comprises a plurality of dosing stations for dispensing a dosed quantity of solid drug portions, a plurality of guiding ducts, a plurality of collecting containers for receiving drug portions guided through the guiding ducts, and at least one discharge and packaging station for transferring drug portions collected by each collecting container to a packaging and for closing the packaging. The guiding ducts are coupled to a transport means for moving the guiding ducts along the dosing stations, wherein each guiding duct is adapted to receive drug portions dispensed from at least one of the dosing stations when the guiding duct is positioned at the at least one dosing station, and to guide the received drug portions to an passage opening of the guiding duct. The collecting containers are also coupled to the transport means so that each collecting container can be positioned at the passage opening of one of the guiding ducts to receive drug portions guided through the guiding duct.
