Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a large-scale reactor is used for decellularization, then mass production capability is improved, but the ability to process small quantities of xenogeneic organ tissue deteriorates

Engineering Contradiction:
Improvemass production capabilityVSAvoidability to process small quantities
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The reactor is divided into multiple independent reaction vessels (first reaction vessel and second reaction vessel), each capable of processing small quantities of tissue separately. This segmentation allows the system to handle small samples effectively while maintaining the infrastructure for scalable processing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The reaction vessels are designed with universal functionality to accommodate different types of xenogeneic organ tissues (cornea, heart, etc.) and process them through the same decellularization protocol. The mesh chambers and circulation systems can handle various tissue types and quantities flexibly.

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

2Quantity of substance

If a large-scale facility is used for decellularization, then processing capacity is improved, but the ease of operation for small samples deteriorates

Engineering Contradiction:

Solution Approach 1:

By dividing the large-scale facility into multiple smaller, independent reaction vessels, each vessel becomes easier to operate and manage. The mesh chambers can be individually accessed, cleaned, and maintained, simplifying operations for small sample processing while the overall system maintains high processing capacity through parallel operations.

Inventive Principle:

Solution Approach 1:

The reaction vessels are designed with universal components including mesh chambers that can accommodate different tissue types, circulation systems that handle various fluids, and heating/cooling systems that work across different processing protocols. This universality enables the system to process detailed tissues from various xenogeneic organs without requiring separate specialized equipment for each tissue type.
