Solution Overview

Problem

The existing production methods for microcarrier tablets face challenges in scaling up production to meet large market demand, with limited throughput and inefficiencies in material preparation and sterilization.

Innovation Solution

A method and apparatus for preparing microcarrier particles using a multi-hole plate to form liquid microspheres through a water-in-oil emulsion process, where the dispersed phase liquid containing synthetic polymers and natural biological macromolecules is sheared to create particles that are then cured and collected.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional microcarrier production methods are used, then microcarrier tablets can be produced, but the throughput is limited and cannot meet large market demand

Engineering Contradiction:
Improveproduction throughputVSAvoidmarket demand supply capacity
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The production process is segmented into multiple functional modules: a multi-hole plate with numerous micro-wells for parallel emulsion formation, a continuous phase liquid flow system for shearing and emulsion formation, and a separate curing system. This segmentation enables simultaneous production of thousands of microcarrier particles, dramatically increasing throughput to meet large market demand.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements continuous production through continuous phase liquid flow that continuously shears dispersed phase liquid through the multi-hole plate, forming emulsions in real-time. The curing process also continues continuously, transforming liquid microspheres into solid microcarrier particles without interruption, thereby maintaining high productivity throughout the production cycle.

Inventive Principle:
Principle #20Continuity of useful action

2Ease of manufacture

If conventional microcarrier production methods are used, then microcarriers can be manufactured, but material handling and sterilization operations become cumbersome

Engineering Contradiction:
Improvematerial handling efficiencyVSAvoidsterilization and processing complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges multiple functions into the multi-hole plate structure: it serves as both the emulsion formation template and the molding cavity for microcarrier particles. The continuous phase liquid flow system combines shearing, emulsion formation, and particle shaping in a single integrated process, eliminating the need for separate material handling and sterilization steps for each component.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system performs self-service through automatic emulsion formation where the continuous phase liquid automatically shears the dispersed phase liquid through the multi-hole plate without manual intervention. The curing process automatically transforms the liquid microspheres into solid particles, and the entire process can be sterilized as a single integrated unit, reducing material handling complexity.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If microcarrier particles are produced with high porosity and controlled size, then they are suitable for 3D cell culture, but the production process becomes more complex

Engineering Contradiction:
Improveparticle size uniformity and porosity controlVSAvoidemulsion formation process complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies local quality by controlling the properties of different phases: the dispersed phase liquid contains synthetic polymers and natural biological macromolecules with specific local properties for porosity, while the continuous phase liquid contains organic solvent and nonionic surfactant with specific local properties for emulsion stability. The multi-hole plate provides uniform local shearing conditions across all micro-wells, ensuring consistent particle size and porosity throughout the batch.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent controls particle size and porosity by changing parameters: adjusting the diameter of micro-wells in the multi-hole plate, controlling the flow rates of dispersed and continuous phase liquids, and adjusting the composition ratios of polymers and surfactants. These parameter changes enable precise control over microcarrier particle size (50-500 μm) and porosity (>90%) without complicating the overall process.

Inventive Principle:
Principle #35Parameter changes
