Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If complex fluidic connections are used to connect multiple microfluidic devices and reservoirs, then the system can perform versatile bioprocess operations, but the device complexity and dead volumes increase leading to unreproducible results

Engineering Contradiction:

Improvebioprocess operation versatilityVSAvoidfluidic connection complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fluidic connection system is segmented into modular components: reservoirs with ports, buffer tanks, microfluidic devices, and intermediate connection elements. Each segment can be independently configured and connected through standardized interfaces, reducing overall system complexity while maintaining versatility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Buffer tanks serve as intermediary elements between reservoirs and microfluidic devices, simplifying the fluidic connection architecture. These intermediaries manage fluid distribution and reduce the number of direct connections needed between reservoirs and devices, thereby reducing dead volumes and improving reproducibility.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Quantity of substance

If batch size is scaled up from screening to industrial manufacturing, then quantitative production is achieved, but protocol parameter consistency deteriorates leading to performance decrease

Engineering Contradiction:

Improveproduction batch sizeVSAvoidprotocol parameter consistency

Core Design Contradiction:

Quantity of substanceVSManufacturing precision

Solution Approach 1:

The bioprocessing device is designed with universal components and standardized fluidic connections that can operate consistently across different batch sizes. The same device architecture used for screening can be scaled for industrial manufacturing, maintaining protocol parameter consistency through modular replication rather than redesign.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system allows for controlled parameter changes during scaling by using buffer tanks to maintain consistent fluidic conditions. Key parameters such as flow rates, pressures, and volumes can be precisely controlled and adjusted while maintaining protocol integrity across different production scales.

Inventive Principle:

Principle #35Parameter changes

3Quantity of substance

If minimal quantities of material are used in microfluidic devices, then high-throughput screening is enabled, but fluidic connection complexity increases

Engineering Contradiction:

Improvematerial quantityVSAvoidfluidic connection architecture

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

Multiple fluidic functions (fluid storage, distribution, control, and waste management) are merged into integrated components such as buffer tanks with multiple ports and combined valve systems. This consolidation reduces the number of separate connection elements needed, simplifying the overall fluidic architecture while supporting minimal material quantities.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A system for processing biological particles including bioprocessing microfluidic devices, reservoirs, buffer tanks and two fluidic connection systems. A first fluidic connection system includes valves and connecting elements between valves, so that each reservoir or port configured to connect a reservoir may be in fluidic connection with each buffer tank, and a second fluidic connection system includes valves and connecting elements between valves, so that each bioprocessing microfluidic device may be in fluidic connection with each buffer tank.
