Code-Based Tampon Dispensing Device With Sensor Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coin-operated tampon vending machines are cumbersome, prone to mechanical issues, and difficult to maintain, often leaving women without access to tampons in public restrooms due to coin availability problems and stock management challenges.
Innovation Solution
A tampon dispensing device with a display, actuator, and controller that uses a code-based system for dispensing tampons via a server connection, allowing users to text a code to receive a tampon, and includes sensors for stock monitoring and maintenance notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a coin-operated vending machine is used to dispense tampons, then the dispensing function is provided, but the ease of operation deteriorates due to coin availability issues and mechanical activation problems
Solution Approach 1:
The patent replaces the mechanical coin-operated system with an electronic code-based dispensing system. Instead of requiring physical coins and mechanical pushbuttons, the system uses a display to show a code, receives verification through a communication interface, and triggers dispensing through an electronic controller that actuates the spindle structure, eliminating mechanical failure points and coin handling requirements
Solution Approach 2:
The patent introduces a communication interface as an intermediary between the user and the dispensing mechanism. The system displays a code to the user, receives the code through text message or other communication methods, verifies it through the communication interface, and then triggers dispensing. This intermediary layer provides a more reliable and user-friendly interaction method compared to direct mechanical operation
2Productivity
If a coin-operated vending machine is used, then tampon dispensing is enabled, but the device complexity increases due to coin slots, mechanical pushbuttons, and registration systems
Solution Approach 1:
The patent extracts and removes the complex mechanical components from the dispensing system. The coin slot, mechanical pushbutton, and coin registration system are completely eliminated. Only the essential dispensing function remains, simplified to a code display, communication interface for verification, and an electronic actuation system that directly controls the spindle structure
Solution Approach 2:
The patent substitutes mechanical components with electronic and software-based systems. The mechanical coin handling and pushbutton activation are replaced by an electronic code verification system that communicates through text messages or other digital means, significantly reducing mechanical complexity while maintaining or improving productivity
3Ease of repair
If a coin-operated vending machine is deployed, then tampon access is provided, but the ease of repair deteriorates due to difficulty in monitoring stock levels and diagnosing mechanical failures
Solution Approach 1:
The patent implements feedback mechanisms through sensors that monitor stock levels and detect dispensing status. The system provides real-time information about tampon availability and operational state, enabling maintenance staff to remotely assess machine status, diagnose issues, and determine when intervention is needed, significantly improving ease of repair and reducing information loss

AI summary
Tampon dispensing devices and methods for using the same are provided. In some embodiments, a tampon dispensing device includes a display that presents one or more codes for receiving a tampon, an actuator that is connected to a spindle structure that dispenses the tampon from a plurality of tampons stored in a storage unit, and a controller that is connected to the display and the actuator, where the controller is configured to: receive, from a server, a code for dispensing one of the plurality of tampons; present the received code on the display; receive, from the server, a request to dispense one of the plurality of tampons from the storage unit; and transmit an instruction to the actuator that causes the actuator to rotate a spindle structure such that the tampon is dispensed from the storage unit into a dispensing area.
