Solution Overview
Problem
Individuals taking multiple medications daily face challenges in distinguishing between them, leading to potential dosage errors due to the complexity of managing various tablets and medications.
Innovation Solution
A dosing method and device that stores active substances in liquid form in storage containers, allowing precise dosing through nozzles into a collecting vessel or onto a substrate, enabling the preparation of customized medications with separate nozzles for each substance to prevent mixing and ensure accurate dosing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple active substances are mixed into a single medicament, then the number of tablets the patient needs to take is reduced, but the precision of dosing each active substance becomes more difficult to control
Solution Approach 1:
The device segments the dosing process by providing separate nozzles for each active substance, allowing individualized dosing control while still delivering multiple substances in a single administration event. Each nozzle can be independently controlled to deliver precise amounts of specific active substances.
Solution Approach 2:
The control device monitors and regulates the dosing process for each active substance independently, enabling precise control of the amount delivered through each nozzle while maintaining the ability to mix multiple substances in a single medicament preparation.
2Manufacturing precision
If separate nozzles are provided for each active substance, then dosing precision is improved, but the device complexity increases
Solution Approach 1:
The device uses a universal nozzle design that can be configured for different active substances, with a control device that manages multiple nozzles through a unified interface. This multi-functional approach allows separate dosing control without proportionally increasing overall system complexity.
Solution Approach 2:
The control device integrates the control mechanisms for multiple nozzles into a unified control system, where the overall controller manages individual nozzle operations. This nested control structure allows precise control of each nozzle while maintaining a manageable level of overall device complexity.
3Manufacturing precision
If active substances are stored in liquid form in storage containers, then dosing flexibility and precision are improved, but the risk of substance mixing before dosing increases
Solution Approach 1:
The device physically segments different active substances into separate storage containers with dedicated nozzles, preventing premature mixing while allowing controlled delivery. Each substance remains isolated in its own container until the dosing moment, maintaining both flexibility and preventing harmful mixing.
Solution Approach 2:
The control device acts as an intermediary that manages the selective activation of different nozzles, ensuring that only the intended active substances are delivered at any given time. This intermediary control prevents unintended mixing while maintaining the benefits of liquid storage flexibility.

Function Achieved in This Case
Enables the precise preparation of medications, reducing the need for multiple tablets per day by allowing pharmacies to create tailored, medication-specific formulations that are easy to administer, minimizing errors and simplifying patient medication management.
Implementation Method 1
a number of drops corresponding to the desired quantity of the active substance is actively pressed through a nozzle onto a substrate or into a collecting vessel
Data Source
AI summary
The invention is directed to a method and a device for the dosing of active substances for the preparation of medicaments. In the context of the dosing method, one or more active substances dissolved in a liquid are stored in a storage container, and, in order to permit dosing, a number of drops corresponding to the desired amount of active substance are forced actively through a nozzle onto a substrate or into a collecting vessel; the device used for this purpose comprises at least one storage container for storage of a liquid, and one or more active substances dissolved therein, and also a nozzle through which a number of drops corresponding to the desired amount of active substance are forced out onto a substrate or into a collecting vessel.
