Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional exosome production methods are used, then exosome formulations can be obtained, but heterogeneity and low productivity limit therapeutic application

Engineering Contradiction:

Improveexosome production efficiencyVSAvoidexosome formulation homogeneity

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The patent transforms parental cells through genetic modification to alter the composition and properties of secreted exosomes. By changing the genetic parameters of parent cells (e.g., introducing specific genes, modifying expression levels), the exosomes produced exhibit enhanced therapeutic factors and more consistent characteristics, simultaneously improving productivity and homogeneity

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates engineered exosomes that function as composite therapeutic agents, combining multiple therapeutic factors (proteins, nucleic acids, lipids) within a single exosome structure. These engineered exosomes integrate multiple functional components that work synergistically to treat complex disorders, achieving both high productivity and functional consistency

Inventive Principle:

Principle #40Composite materials

2Reliability

If exosome delivery efficiency is improved for therapeutic application, then treatment effectiveness increases, but immune system activation may occur

Engineering Contradiction:

Improvetherapeutic delivery efficiencyVSAvoidimmune system activation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent utilizes the immune system's natural recognition mechanisms by engineering exosomes to display specific surface markers that guide immune cells to deliver therapeutic cargo precisely to target tissues. The immune system's phagocytic activity, normally a potential source of inflammation, is harnessed to enhance targeted delivery and reduce off-target immune activation

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The engineered exosomes serve as intermediary carriers that mediate between therapeutic agents and target cells. By modifying exosome surface properties and internal cargo composition, they facilitate controlled release of therapeutic factors at target sites while minimizing recognition by non-specific immune cells, thus improving delivery efficiency without triggering harmful immune responses

Inventive Principle:

Principle #24Intermediary (Mediator)
