Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual mixing of multi-ingredient mixtures is inefficient, imprecise, and potentially hazardous, particularly for pharmaceuticals, due to the need for precise concentration and safety concerns.
Innovation Solution
A compounder apparatus with a manifold system that docks multiple reservoirs, extracts fluids, mixes them with a diluent in a controlled mixing chamber, and fills a destination reservoir, incorporating containment assemblies with elastomeric septa and variable-volume housing to ensure safety and precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual mixing of ingredients is performed, then operational simplicity is maintained, but mixing precision and safety deteriorate
Solution Approach 1:
The patent replaces manual mechanical mixing with an automated mixing apparatus that uses mechanical agitation mechanisms. The system automatically measures, transfers, and mixes ingredients according to predetermined formulas, eliminating manual intervention while ensuring precise mixing ratios and concentrations.
Solution Approach 2:
The mixing apparatus is designed to autonomously perform the complete mixing process without human intervention. The system self-regulates ingredient dosing, mixing speed, duration, and temperature control, making the process both simple to operate and highly precise through automated feedback mechanisms.
2Device complexity
If manual mixing of ingredients is performed, then device complexity is reduced, but productivity and efficiency deteriorate
Solution Approach 1:
The mixing apparatus is divided into modular functional units: ingredient storage modules, automated dosing mechanisms, mixing chambers, and control systems. Each module performs a specific function independently, allowing the system to maintain relatively simple individual components while achieving high overall productivity through coordinated operation.
Solution Approach 2:
The system pre-programmes mixing formulas, ingredient quantities, and process parameters before operation. Ingredients are pre-stored in designated containers, and the control system pre-calculates dosing requirements, enabling rapid execution of mixing tasks without complex real-time decision-making, thus improving efficiency without excessive complexity.
3Device complexity
If manual mixing of hazardous ingredients is performed, then equipment requirements are minimized, but safety deteriorates
Solution Approach 1:
The patent introduces containment chambers and sealed transfer mechanisms as intermediary barriers between hazardous ingredients and the operator. The automated system handles hazardous materials within enclosed environments, using sealed conduits and interlocked access points that prevent exposure while maintaining manageable equipment complexity through standardized safety components.

AI summary
A system including a containment assembly for enclosing a medication container may comprise a first housing portion or interface portion having a proximal end and a distal end. The interface portion may include a housing wall which defines a channel spanning from the proximal end to the distal end. The channel may be open at the proximal and distal end. The containment assembly may further comprise only two pierceable septa configured to form a barrier to the channel. The containment assembly may further comprise a variable-volume housing portion having a variable volume chamber. The variable-volume portion chamber of the variable-volume housing portion may be in fluid communication with the distal end of the channel.
