Selective Vial Access Container With Curtain-Guided Secure Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated dispensing machines (ADMs) struggle to securely manage and dispense medicaments in vial form, particularly those with additional security measures, as they often lack configurations for devices that handle vials and other forms that differ from the standard containers, and there are some medications that require secure and efficient access to vials.
Innovation Solution
A container system with a housing, track, and curtain mechanism that allows selective access to a single vial, controlled by a drive mechanism and controller, ensuring secure and efficient dispensing of vials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lid is used to secure the container, then security is improved, but access efficiency deteriorates
Solution Approach 1:
The container is divided into two functional parts: a secure lid that remains closed during storage and a movable curtain that can be selectively opened. This segmentation allows the lid to maintain security while the curtain provides efficient access when needed, resolving the contradiction between security and access efficiency.
Solution Approach 2:
The curtain is designed as a dynamic, movable element that can transition between open and closed states. Unlike the static lid that requires unlocking mechanisms, the curtain can be quickly moved to provide access, maintaining security when closed while enabling rapid access when opened, thus resolving the efficiency-security tradeoff.
2Quantity of substance
If multiple vials are stored in the container, then storage capacity is improved, but access time deteriorates
Solution Approach 1:
The curtain is extracted as a separate access mechanism that can be opened to reveal specific vials in the track. This allows multiple vials to be stored in the container while the curtain can be selectively opened to access individual vials quickly, eliminating the need to open the entire container lid and thus reducing access time while maintaining high storage capacity.
3Manufacturing precision
If a track system is used to organize vials, then dispensing precision is improved, but device complexity deteriorates
Solution Approach 1:
The track system is merged with the curtain mechanism into a single integrated structure. The curtain runs along the track and can be moved to access vials at different positions. This combination provides precise dispensing capability through the organized track system while avoiding excessive complexity by integrating the access mechanism directly into the storage structure rather than adding separate complex retrieval systems.

AI summary
A container for a machine for dispensing vials containing a medicament includes: a housing including a receptacle with an internal compartment and a lid, the receptacle including a track in the internal compartment, the track configured to receive a plurality of medicament vials; a curtain connected with the housing, the curtain configured to form a gap above the track sized to permit access to a vial stored in the track; a drive mechanism mounted to the housing; and a controller operatively connected with the drive mechanism. The drive mechanism is configured to receive signals from the controller to selectively drive either the curtain or vials in the track so that a single vial is positioned below the gap.
