Stackable Pill Tray Dispensing for Multi-Regimen Medication Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pill dispensers are not modular, stackable, or scalable, making it difficult to manage multiple medication regimens efficiently.
Innovation Solution
An automated modular pill dispensing device with stackable trays and a base unit, featuring a controller, user interface, and communication ports, which selectively dispenses pills according to a regimen, using actuators and sensors to manage pill compartments and notify users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional non-modular pill dispensers are used, then the device structure is simple, but the device cannot be expanded to manage multiple medication regimens efficiently
Solution Approach 1:
The pill dispenser is divided into modular components: a base unit and multiple stackable pill trays. Each tray is an independent module that can be stacked vertically on the base unit. This segmentation allows the system to scale from a single tray to multiple trays depending on the number of medication regimens needed, resolving the contradiction between versatility and complexity by allowing incremental expansion.
Solution Approach 2:
The base unit is designed with universal communication interfaces and control capabilities that can manage any number of pill trays. Each tray uses standardized communication ports that interface with the base unit's controller, allowing the same base unit to handle multiple different medication regimens across different trays. This multi-functionality enables the system to adapt to various medication management needs without requiring completely different device structures.
2Ease of operation
If multiple separate pill dispensers are used for different regimens, then each regimen can be managed independently, but the device occupies more space and is harder to manage
Solution Approach 1:
Multiple pill trays are nested vertically by stacking them on top of each other on the base unit. This vertical nesting arrangement allows multiple medication regimens to be managed within a compact footprint, significantly reducing the horizontal space occupied compared to using separate dispensers. The nested structure maintains independent management of each regimen while consolidating the overall device space.
Solution Approach 2:
The system transitions from a horizontal arrangement of separate dispensers to a vertical stacking configuration. By utilizing the vertical dimension, multiple pill trays can be arranged one above another, each accessible through the centralized base unit interface. This dimensional change reduces the area occupied on surfaces while maintaining the capability to manage multiple regimens independently through the unified controller.
3Reliability
If manual pill tracking is used, then the device is simple, but users lose track of medication timing and regimens
Solution Approach 1:
The base unit includes a controller that receives status information from each pill tray through communication ports and provides feedback to users via a user interface. The system tracks the position and status of pills in each compartment, monitoring medication dispensing in real-time. This feedback mechanism ensures accurate medication timing by notifying users when pills are due, resolving the contradiction between reliability and complexity through automated monitoring.
Solution Approach 2:
The system performs automated tracking and monitoring of multiple medication regimens without requiring user intervention. The controller automatically manages the dispensing schedule, tracks pill consumption, and provides notifications. This self-service capability eliminates the need for manual tracking while maintaining simple operation through centralized control, allowing the system to reliably manage complex multi-regimen schedules autonomously.

AI summary
The automated modular pill dispensing device is for selectively dispensing pills of a pill regimen to a patient. The dispensing device includes a base unit having a pill dispensing chute leading to a pill receptacle area. A plurality of stackable pill trays each include a series of pill compartments. The plurality of stackable pill trays each include communication ports for communicatively interfacing with the pill tray communication interface of the base unit and adjacent stackable pill trays above and below. Each stackable pill tray includes an opening in the tray base, aligned with the pill dispensing chute of the base unit, and an actuator configured to selectively advance the series of pill compartments towards the pill hopper in response to the controller so that pills therein will be dispensed, in accordance with the pill regimen, through the pill hopper and via the pill dispensing chute to a pill receptacle positioned at the pill receptacle area.
