Solution Overview

Problem

Existing single-use disposable separation equipment in pharmaceutical and biotechnology fields is manufactured and delivered as a single entity, limiting flexibility and increasing complexity, as both rotating parts and tube connections are integrated into one unit, making it difficult to manage and reuse.

Innovation Solution

A modular centrifugal separator system is designed with an exchangeable separation insert and tube kit, allowing these components to be handled and supplied separately, reducing complexity and enabling different combinations for various applications, with a removable sealing member ensuring sterility and ease of assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If disposable separation equipment is manufactured as a single entity integrating rotating parts and tube connections, then sterility is maintained and handling is simplified, but flexibility is limited and complexity increases

Engineering Contradiction:
ImprovesterilityVSAvoidflexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The disposable separation equipment is divided into separate modules: an exchangeable separation insert (containing the rotor casing and separation elements) and an exchangeable tube kit (containing fluid connections). This segmentation allows each module to be optimized independently and enables flexible recombination for different applications while maintaining sterility through separate packaging and assembly protocols.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If disposable separation equipment is manufactured as a single entity, then assembly is simplified, but device complexity increases and manufacturing becomes less efficient

Engineering Contradiction:
Improveassembly simplicityVSAvoidequipment complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

By segmenting the equipment into standardized modules with defined interfaces, the overall system complexity is reduced. Each module can be manufactured independently using optimized processes, and the standardized interfaces simplify assembly instructions and handling procedures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base unit is designed as a universal platform that can accommodate different types of separation inserts and tube kits through standardized interfaces. This multi-functionality reduces the need for multiple specialized devices, thereby reducing overall equipment complexity while maintaining ease of operation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If rotating parts and tube connections are integrated into one unit, then handling is simplified, but manufacturing efficiency decreases and supplier logistics become less flexible

Engineering Contradiction:
Improvehandling simplicityVSAvoidmanufacturing efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

Separating rotating parts (in the separation insert) from tube connections (in the tube kit) allows parallel manufacturing processes for each module. Different suppliers can manufacture different modules simultaneously, improving overall productivity and enabling more flexible logistics and inventory management.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The separation insert and tube kit are designed to combine easily through standardized interfaces during final assembly. This merging maintains handling simplicity by creating a complete functional unit at the point of use, while the modular approach upstream improves manufacturing efficiency.

Inventive Principle:
Principle #5Merging (Combining)
