Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for preparing solutions by dissolving solid molded bodies in a solvent lack flexibility in controlling the concentration of ingredients, especially when varying target concentrations of different ingredients are required, and are limited by the size and shape of tablets with fixed ingredient distributions.
Innovation Solution
A dosing device that allows for the controllable selective addition of solid molded bodies from storage containers with different ingredients and concentrations, using a code recognition system to identify the contents and an ejector unit to convey the correct amounts into a mixing container, where the tablets can be broken into parts for finer dosing and increased surface area, enabling precise control of ingredient concentrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If tablets with fixed ingredient distributions are used, then the device structure is simple, but the flexibility in controlling ingredient concentrations is limited
Solution Approach 1:
The invention divides the tablet into multiple segments or layers, each containing different ingredients or concentrations of ingredients. This allows the single tablet structure to provide multiple concentration levels and ingredient combinations, thereby improving adaptability without requiring multiple separate tablets or complex device structures.
Solution Approach 2:
Different regions or segments of the tablet are designed with different ingredient compositions and concentrations. This local differentiation enables the tablet to provide varied pharmacological effects or treatment parameters within a single unit, enhancing the device's versatility while maintaining structural simplicity.
2Manufacturing precision
If tablets of fixed size and shape are used, then the manufacturing is simple, but the precision in dosing and concentration adjustment is limited
Solution Approach 1:
The tablet is segmented into multiple portions or layers with different ingredient concentrations. This segmentation enables precise dosing control by allowing selective dissolution or extraction of specific segments, thereby improving manufacturing precision while maintaining the simplicity of producing a single tablet format.
Solution Approach 2:
The invention varies parameters such as tablet density, composition distribution, or segment size within the same tablet structure. This allows for precise dosing and concentration adjustment by changing physical or chemical parameters rather than requiring different tablet sizes or shapes, thus maintaining ease of manufacture while improving precision.
3Adaptability or versatility
If the solution volume is small, then the application is versatile (e.g., medical use), but the control of ingredient concentrations becomes more difficult
Solution Approach 1:
The tablet is divided into segments with different ingredient concentrations, allowing precise control even in small solution volumes. By selecting specific segments for dissolution, the system can achieve accurate concentration control in small volumes, maintaining versatility for applications like medical treatments while improving dosing precision.
Solution Approach 2:
Different segments of the tablet have locally optimized ingredient compositions tailored for small volume applications. This local quality differentiation enables precise concentration control in small solution volumes by ensuring that only the required amount of each ingredient is released, thereby maintaining application versatility while improving manufacturing precision.

Implementation Method 1
tablets are removed individually from a storage container by means of an ejector and conveyed into a mixing container, where the tablets dissolve, so that a homogenous solution is obtained
Implementation Method 2
a deflecting device which exerts a force on the solid molded body in a second direction after the solid molded body has been conveyed in the first direction

AI summary
An apparatus for preparing a medical solution by adding substances present in solid molded bodies to a solvent comprises a mixing container, which can be filled through an inlet with a solvent and from which the solution can be supplied to an application via an outlet, and which also has a feed port, through which the solid molded body can be introduced into the mixing container, as well as a dosing apparatus for controllable selective addition of solid molded bodies or parts thereof with different ingredients and/or different concentrations of ingredients from one or more storage containers, in which one or more corresponding receptacles of the apparatus are stored and in which the solid molded bodies are stored in such a way that they can be removed. The apparatus may also have a code detection device for detecting and analyzing a machine-readable code associated with a storage container, said code containing information about which ingredients are contained in the solid molded bodies stored in the respective storage container.
