Locking Canister with Worm Gear Shutter for Medication Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to secure and monitor high-value medications, particularly narcotics, to prevent diversion and unauthorized use, as they are prone to theft and misuse due to their monetary value and potential for abuse.
Innovation Solution
A locking canister system with a medication release mechanism and multiple locking mechanisms, including a retractable rotating shutter and worm gear, that can only be unlocked when connected to a base unit and authorized, ensuring secure storage and controlled dispensing of medications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is implemented to prevent unauthorized access to medications, then security and theft prevention are improved, but device complexity increases
Solution Approach 1:
The locking canister is divided into separate functional components: a canister housing for medication storage, a canister cover with locking mechanisms, and a base unit with control electronics. This segmentation allows each component to be optimized independently while maintaining overall security functionality.
Solution Approach 2:
The patent introduces a base unit as an intermediary component that mediates between the locking mechanism and the medication canister. The base unit contains the control electronics and communication interfaces, separating the security control functions from the simple mechanical locking structure.
2Reliability
If multiple locking mechanisms are used to secure the canister, then unauthorized access prevention is improved, but ease of operation deteriorates
Solution Approach 1:
The locking mechanism incorporates a spring-loaded shutter that automatically returns to the closed position after medication dispensing. The biasing mechanism provides self-service by automatically resetting the locking state without requiring manual intervention, simplifying operation while maintaining security.
Solution Approach 2:
The locking system operates in periodic cycles: locked during transit and storage, temporarily unlocked for authorized dispensing, then automatically re-locked. This periodic operation pattern simplifies user interaction by eliminating the need for manual re-locking after each dispensing event.
3Reliability
If the canister is locked during transit and storage, then theft prevention is improved, but medication dispensing speed deteriorates
Solution Approach 1:
The canister is pre-configured with an authorized unlocking mechanism that can quickly transition from locked to unlocked state when proper authorization is provided. The spring-loaded shutter is pre-positioned to rapidly open upon unlocking, enabling fast medication dispensing immediately after authorization without manual manipulation delays.
Solution Approach 2:
The shutter mechanism transitions dynamically between locked and unlocked states. During transit and storage, the shutter remains firmly locked. Upon authorized unlocking, the spring bias rapidly drives the shutter open, providing quick medication access. This dynamic behavior allows the system to optimize for both security during transport and speed during dispensing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively prevents unauthorized access and theft by locking the canister during transit and storage, allowing controlled dispensing only when properly connected to an automated dispensing unit, ensuring secure and compliant medication distribution.
Implementation Method 1
At least one of the one or more locking mechanisms may comprise a worm gear for selectively rotating the retractable portion between the closed position and the retracted position. At least one of the one or more locking mechanisms may comprise a worm gear for selectively locking the retractable portion in at least one of the closed position and the retracted position.
Implementation Method 2
The one or more locking mechanisms may comprise one or more movable tabs each comprising: a locked position for locking the retractable portion in the closed position; an unlocked position for permitting the retractable portion to be selectively moved between the retracted position and the closed position; and a biasing mechanism for biasing the one or more movable tabs in the locked position.
Data Source
AI summary
In certain embodiments, a lockable canister for retaining and selectively dispensing medications is disclosed. To prevent drug diversion, a plurality of doses of medication may be loaded into the locking canister at a central pharmacy and then the canister may be locked to prevent unauthorized removal of medication in transit to a remote automated dispensing unit that may be located in a remote pharmacy. The lockable canister may include a canister housing and a canister cover that may be locked to the canister housing to enclose the plurality of doses of medication. The canister cover may include tamper evident or tamper resistant features. The canister may include one or more locking mechanisms to prevent unauthorized access to the medication in the canister in transit or before it is specifically authorized for dispensing.
