Solution Overview

Problem

Conventional medication storage and dispensing workstations lack efficient and secure access mechanisms for discrete storage compartments, particularly in healthcare environments where secure and controlled distribution of medications is crucial.

Innovation Solution

A medication storage and dispensing workstation with a linear drawer assembly featuring discrete, extensible compartments and a dual-actuator system that allows for lateral movement of compartments without opening the main drawer cover, along with a host control module for controlled access and inventory management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional drawer assembly with a single cover is used, then the structure is simple and manufacturing is easy, but secure access to specific compartments is not achieved and unauthorized access cannot be prevented

Engineering Contradiction:
Improvesecure accessVSAvoiddrawer assembly structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The drawer assembly is segmented into multiple discrete compartments, each with its own cover and actuator mechanism. This segmentation allows independent control of each compartment, enabling secure access to specific compartments while maintaining overall structural organization. The cover for each compartment can be opened or closed independently, providing granular security control.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements a nested structure where discrete compartments are arranged within the drawer assembly, and each compartment contains its own cover and actuator mechanisms. The compartments are nested within the drawer body, creating a hierarchical structure that provides both security and organizational efficiency.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If the drawer assembly is opened to access medications, then all compartments become accessible, but unauthorized access to specific compartments cannot be prevented and security is compromised

Engineering Contradiction:
Improvecontrolled accessVSAvoidcompartment access
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

Each compartment has its own独立的 cover and actuator mechanism, allowing individual compartments to be accessed without opening the entire drawer assembly. This segmentation enables controlled access where only the specific compartment needed by the user is opened, maintaining security for other compartments.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The drawer assembly incorporates dynamic control through actuators that can independently open or close specific compartment covers based on user authentication or system commands. This dynamic control allows the system to adapt access permissions for different users and different compartments, providing flexible security management.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If multiple discrete compartments are added to the drawer assembly, then organized storage and controlled access are achieved, but device complexity and manufacturing difficulty increase

Engineering Contradiction:
Improvestorage organizationVSAvoiddrawer assembly production
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The drawer assembly is divided into modular discrete compartments that can be manufactured separately and then assembled together. This modular approach allows for standardized production of compartment units, reducing overall manufacturing complexity despite the increased number of components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The actuator mechanisms and cover designs are made universal across all compartments, allowing the same components to be used throughout the drawer assembly. This standardization simplifies manufacturing and maintenance while providing the versatility of multiple independently controlled compartments.

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

4Reliability

If a dual-actuator system is implemented for each compartment, then precise control and secure access are achieved, but device complexity and cost increase

Engineering Contradiction:
Improveaccess controlVSAvoidactuator system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The actuator system is segmented into modular units, with each compartment having its own actuator mechanism. This segmentation allows for independent control of each compartment while using standardized actuator designs, reducing overall system complexity through modularity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The actuator system implements dynamic control where actuators can be selectively activated based on user authentication, compartment type, or system requirements. This dynamic activation reduces the need for complex hardware in all compartments simultaneously, as actuators can be enabled or disabled based on current operational needs.

Inventive Principle:
Principle #15Dynamics

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.
