Solution Overview

Problem

There is a global demand for animal protein, particularly collagen, which is constrained by ethical and economic concerns related to slaughtering animals, and animal-derived collagens often contain undesirable materials like xenobiotics and high caloric ingredients.

Innovation Solution

Collagens naturally occurring extracellularly in animal species are expressed in non-animal organisms such as plants, fungi, and bacteria, providing a source of collagen without the need for animal slaughter, allowing for posttranslational modifications and various forms of expression.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If collagen is obtained from slaughtered animals, then high quality collagen is produced, but ethical concerns and economic constraints arise

Engineering Contradiction:
Improvecollagen qualityVSAvoidethical concerns
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies the copying principle by using genetic engineering to transfer animal collagen genes into non-animal organisms (plants, fungi, bacteria). These host organisms then produce collagen that is identical or highly similar to the original animal collagen, eliminating the need for animal slaughter while maintaining product quality and purity.

Inventive Principle:
Principle #26Copying

2Quantity of substance

If collagen is obtained from slaughtered animals, then sufficient quantity is produced, but undesirable materials such as xenobiotics and hormones are present

Engineering Contradiction:
Improvecollagen quantityVSAvoidundesirable materials
Core Design Contradiction:
Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The patent applies the extraction principle by isolating and transferring only the specific collagen gene sequences from animals into non-animal host organisms. This selective extraction ensures that only the desired collagen protein is produced without co-producing other animal-derived substances such as xenobiotics, hormones, or other contaminants that would be present in traditional animal-derived collagen.

Inventive Principle:
Principle #2Taking out (Extraction)

3Object-affected harmful factors

If non-animal organisms are used for collagen expression, then ethical concerns are addressed and purity is improved, but production efficiency may be reduced

Engineering Contradiction:
ImprovepurityVSAvoidproduction efficiency
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The patent applies parameter changes by optimizing various expression parameters in non-animal host organisms, including selecting appropriate promoters, optimizing culture conditions, choosing suitable host strains, and modifying gene sequences for better expression. These parameter optimizations enable high-level collagen production in plant, fungal, and bacterial systems while maintaining the purity advantages of non-animal sources.

Inventive Principle:
Principle #35Parameter changes
