Dispenser Magnetic Latching System to Prevent Unauthorized Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensers for consumable products face issues with unauthorized access and tampering due to easily pickable or forceable locks, and traditional robust locks are costly and not feasible.
Innovation Solution
A dispenser with an internal locking mechanism using ferrous pins and a magnetic key that allows secure locking and unlocking from outside without physical contact, where the pins engage or disengage the hinge to open or close the door.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional robust locks are installed to prevent unauthorized access, then security is improved, but cost increases significantly
Solution Approach 1:
The patent replaces traditional mechanical locks with a magnetic field-based locking mechanism. A magnet is positioned inside the dispenser body to attract a ferromagnetic material in the door, creating a locking force without mechanical contact. This eliminates the need for expensive mechanical lock components while maintaining security, directly resolving the contradiction between security and cost.
2Reliability
If traditional locks with key holes are placed on the exterior, then security is provided, but dirt accumulation increases and hygiene deteriorates
Solution Approach 1:
The patent nests the magnetic locking mechanism entirely within the dispenser body. The magnet is positioned inside the dispenser and the ferromagnetic material is embedded in the door, creating an internal locking system. This eliminates external key holes and protruding lock components that would otherwise trap dirt, resolving the contradiction between security and hygiene.
Solution Approach 2:
The patent extracts the key hole and external lock components from the dispenser exterior, removing the source of dirt accumulation. The locking function is maintained through the magnetic field acting through the dispenser wall, eliminating the need for external access points that would compromise hygiene.
3Ease of manufacture
If simple locking mechanisms are used to reduce cost, then manufacturing cost decreases, but security against picking and forcing deteriorates
Solution Approach 1:
The patent replaces vulnerable mechanical lock components (which can be picked or forced) with a magnetic field-based system. The magnetic attraction between the magnet and ferromagnetic material creates a secure locking force that cannot be easily picked or forced, while the components remain simple and cost-effective to manufacture.
