Solid Dosage Dispenser with Graphical Restocking Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing multiple medications with different consumption rules can lead to confusion, missed doses, overdoses, and noncompliance, especially for patients who need to take medications on the go, due to the complexity and non-intuitive operation of existing in-home dosage dispensers.
Innovation Solution
A solid dosage dispensing apparatus with a user interface, including a display and communication circuitry, that allows users to select and confirm medication types, quantities, and locations, provides alarms for incorrect placement, and updates inventory via internet or cellular connections, enabling intuitive restocking and travel pack dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated in-home dosage dispensers are used, then medication management is automated and dosing accuracy is improved, but the device complexity and difficulty of operation increase
Solution Approach 1:
The system enables self-service through automated dispensing mechanisms that automatically release medications at programmed times without requiring patient intervention. The electronic controller autonomously manages dosing schedules, container rotation, and dispensing operations, allowing the device to serve itself while maintaining high dosing accuracy.
Solution Approach 2:
The system incorporates feedback mechanisms including sensors that detect container presence, dosage dispensing status, and device operational state. This feedback is transmitted to the electronic controller which adjusts operations accordingly, ensuring accurate dosing while providing status information to reduce user confusion through clear visual or audible signals.
2Reliability
If complex refilling procedures are implemented, then inventory management is improved, but the refilling process becomes difficult and error-prone
Solution Approach 1:
The system performs preliminary actions by pre-programming dosing schedules and container configurations before refilling is needed. The electronic controller maintains an inventory database and pre-calculates refilling requirements, so when refilling occurs, the process is simplified by following pre-established protocols rather than requiring complex real-time decisions.
Solution Approach 2:
The system replaces manual mechanical refilling procedures with an electronically controlled process. The electronic controller manages container identification, location assignment, and dispensing mechanics through electronic signals rather than manual manipulation, reducing refilling errors while maintaining reliable inventory management through digital tracking.
3Stability of the object's composition
If the dispenser operates on a fixed schedule, then dosing consistency is improved, but flexibility for patient travel and schedule changes is reduced
Solution Approach 1:
The system incorporates dynamic capabilities by allowing the electronic controller to adjust dosing schedules in real-time based on user input or external communications. The programmed schedule can be modified remotely or locally, enabling the device to adapt to patient travel plans or medical schedule changes while maintaining consistent dosing through updated electronic programming rather than fixed mechanical timing.
Solution Approach 2:
The system achieves universality by integrating multiple functions: automated dispensing, remote communication capabilities, schedule modification, and travel mode operation. This multi-functionality allows the device to operate consistently on a fixed schedule when needed while also adapting to flexible requirements through remote programming or local adjustments, serving both stable and variable dosing needs.
4Ease of operation
If intuitive user interface is designed, then ease of use is improved, but device complexity increases
Solution Approach 1:
The user interface is segmented into simple, discrete interaction elements such as individual buttons for specific actions (dispense, refill, travel mode) rather than complex menus. This segmentation allows elderly or medically impaired patients to easily understand and operate the device without cognitive overload, while the underlying electronic controller handles the complexity of coordinating multiple containers and dosing schedules.
Solution Approach 2:
The system uses an intermediary electronic controller that translates simple user interface inputs into complex coordinated actions. When a user presses a simple button, the intermediary controller interprets the input, checks the current state, and executes the appropriate sequence of operations across multiple components, thereby providing intuitive operation while managing device complexity internally rather than at the user interface level.

AI summary
A solid dosage dispensing apparatus comprising a user interface including a display. A plurality of containers are provided from which solid dosages are dispensed. The apparatus includes a controller operative during a stocking mode to: (i) present on said display a list of different solid dosage types available for stocking; (ii) receive an indication of a selected solid dosage type; (iii) graphically indicate on the display a container location at which the selected dosage type is to be located; and (iv) confirm container removal from the container location and subsequent container replacement in that location. During a travel pack mode, the controller is operative to: (i) present on said display a prompt to indicate a duration for which a travel pack is to be stocked; (ii) receive an indication of the duration; and (iii) cause dispensing of dosage types for the duration that would otherwise be dispensed by said apparatus as they are to be administered. In some preferred embodiments, the solid dosage dispensing apparatus may include a readable indicia reader such as a RFID unit.
