Rotating Multi-Latch Drawer Release for Secure Medication Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Securable medication dispensing cabinets often require complex mechanics and motors, reducing storage space and increasing costs, while also posing risks due to uncontrolled access.
Innovation Solution
The use of independently actuated drawers with a radial activation member and actuator system that allows for rotational movement to open containers without requiring cabinet-mounted motors, providing secure access to individual containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex mechanics and motors are attached to the cabinet to lock medication containers, then security and access control are improved, but storage space is reduced and manufacturing cost increases
Solution Approach 1:
The actuation mechanism is extracted from the cabinet structure and integrated directly into the drawer. The drawer becomes an independent unit with its own motor and latch mechanism, eliminating the need for cabinet-mounted mechanics. This extraction allows the cabinet to maintain full storage space while the drawer provides localized security functionality.
Solution Approach 2:
The system is segmented into independent drawer units, each with its own actuation mechanism. Instead of a centralized locking system in the cabinet, each drawer is a self-contained module with separate motor, activation member, and latch components. This segmentation distributes the security function across multiple independent units, preserving cabinet storage volume.
2Reliability
If complex mechanics and motors are attached to the cabinet to lock medication containers, then security and access control are improved, but manufacturing cost increases
Solution Approach 1:
The drawer is designed as a modular unit with standardized components (motor, activation member, latch mechanism) that can be manufactured independently and assembled. This modular segmentation allows for economies of scale in component production and simplifies quality control, reducing overall manufacturing complexity and cost compared to integrated cabinet-mounted systems.
Solution Approach 2:
By extracting the actuation mechanism from the cabinet and placing it in the drawer, the patent creates interchangeable, standardized components that can be mass-produced. The drawer assembly becomes a replaceable module, simplifying manufacturing workflows and reducing tooling costs compared to custom cabinet-integrated mechanisms.
3Ease of operation
If a radial activation member with multiple actuators is used to access multiple containers, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The activation member is designed as a universal interface that can actuate multiple different latch mechanisms through rotational movement. A single activation member with multiple actuators positioned at different radial distances can engage with various container types and configurations, providing multi-functionality that simplifies operation across diverse storage needs while managing complexity through standardized actuation geometry.
Solution Approach 2:
The activation member operates in a radial dimension, with actuators positioned at different radial distances from the rotation axis. This dimensional arrangement allows multiple actuation points to be accessed through a single rotational motion, converting a potentially complex multi-axis problem into a simpler single-axis rotational interface that is easier to operate.

AI summary
A drawer that includes a container and an activation member is disclosed. The container includes a receptacle and a lid. The lid moves between an open position allowing access to the receptacle and a closed position restricting access to the receptacle. The container further includes a fastener, coupled to the lid, to fasten the lid to the receptacle when the lid is in the closed position. The activation member moves radially around a longest axis of the activation member, and includes an actuator. When the activation member is rotated in a first direction, the actuator is placed into a first orientation relative to the fastener. When the activation member is rotated in a second direction opposite the first direction, the actuator is placed into a second orientation relative to the fastener such that the actuator actuates the fastener to cause the lid to move into the open position.
