Medication Drawer Assembly With Discrete Compartments for Secure Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medication storage and dispensing workstations lack efficient and secure access mechanisms for discrete storage compartments, particularly in decentralized medication management systems, where multiple dispensing sites are remote from centralized locations, leading to potential misaccess and inefficiencies in medication distribution.
Innovation Solution
A medication storage and dispensing workstation with a linear drawer assembly featuring discrete, laterally extendable compartments, actuated by first and second actuators, and a host control module for controlled access, ensuring secure and efficient retrieval of medications, with sensors and locking mechanisms to prevent unauthorized access and facilitate correct compartment identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional storage assemblies with simple drawer structures are used, then device complexity is reduced, but access control precision and security are insufficient
Solution Approach 1:
The drawer assembly is segmented into multiple discrete compartments, each with independent access control mechanisms. This segmentation allows precise control over which compartments can be accessed by authorized users, thereby improving access control precision without requiring complete redesign of the entire storage system.
Solution Approach 2:
The patent implements a nested drawer structure where discrete compartments are positioned within the drawer assembly. This nesting arrangement allows multiple levels of access control - the main drawer can be locked while individual compartments within it can be independently accessed or locked, resolving the contradiction between security and operational complexity.
2Adaptability or versatility
If discrete compartments are added to the drawer assembly, then medication organization and security are improved, but device complexity increases
Solution Approach 1:
The drawer assembly is divided into multiple discrete compartments that can be independently configured for different medication types. This segmentation improves medication organization and adaptability while maintaining a relatively simple overall structure through modular design.
Solution Approach 2:
The discrete compartments are designed to be extensible laterally, allowing dynamic adjustment of compartment sizes and configurations based on medication storage needs. This dynamic capability enhances adaptability without requiring a completely complex fixed structure.
3Productivity
If lateral extension of discrete compartments is enabled, then access efficiency and security are improved, but mechanical complexity increases
Solution Approach 1:
Instead of requiring full drawer extraction for accessing any medication, the system enables partial action by allowing individual discrete compartments to extend laterally only when needed. This improves access efficiency for specific medications while avoiding the mechanical complexity of moving the entire drawer assembly.
Solution Approach 2:
The actuator mechanism serves as an intermediary between the control system and the discrete compartments, enabling automated lateral extension of only the required compartments. This intermediary approach improves access efficiency while containing mechanical complexity to specific actuation points rather than the entire drawer structure.
4Reliability
If automated actuators are implemented for compartment access, then access control precision is improved, but device complexity and cost increase
Solution Approach 1:
The discrete compartments are designed to be self-extending through integrated actuators that automatically position the compartments when access is required. This self-service mechanism improves access control precision by eliminating manual intervention while keeping the overall system relatively simple through decentralized actuation.

AI summary
A storage device having discrete drawers includes a housing having a frame assembly. A drawer assembly is movably received in the housing. A cover is fixedly mounted atop the drawer assembly preventing access to the contents of the drawer assembly. The drawer assembly is further divided into at least two discrete compartments. An actuator is connected to the frame assembly, the actuator operating to move the drawer assembly along a drawer slide slidably outward from the housing. At least two second actuators are connected to said drawer assembly, each actuator operating to move one of the at least two discrete compartments outward from the drawer assembly such that the cover does not move along with the compartment.
