Solution Overview

Problem

Current medical treatments for wound healing and inflammation management lack effective, non-invasive solutions that utilize the therapeutic potential of placental tissue components, particularly the amnion and chorion layers, which are rich in bioactive factors and collagen types.

Innovation Solution

Development of micronized compositions comprising dehydrated amnion and chorion layers, where the amnion layer's epithelium is not substantially removed, formulated into liquids or gels, for topical or injectable applications to enhance wound healing and alleviate joint inflammation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If placental tissue is used for wound healing and inflammation management, then therapeutic effectiveness is improved through delivery of bioactive factors and collagen, but the complexity of preparing and formulating the tissue into usable compositions increases

Engineering Contradiction:
Improvetherapeutic effectivenessVSAvoidpreparation and formulation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The placental tissue is segmented into distinct micronized particles of amnion and chorion layers, each retaining their unique bioactive properties. This segmentation allows for standardized processing and formulation while preserving the therapeutic components in a manageable particle form that can be easily incorporated into various delivery systems.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tissue undergoes controlled dehydration and micronization processes that change its physical parameters (moisture content, particle size) while preserving its biochemical integrity. These parameter changes transform the fresh tissue into a stable, shelf-ready formulation that maintains therapeutic effectiveness without requiring complex cold chain storage or preparation infrastructure.

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If the amnion layer is dehydrated and micronized, then the composition becomes more stable and easier to formulate, but the epithelium layer may be damaged or lost

Engineering Contradiction:
Improvecomposition stabilityVSAvoidepithelium layer integrity
Core Design Contradiction:
Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

The epithelium layer is identified and protected as a critical component before the dehydration and micronization processes begin. Processing parameters are pre-optimized to ensure the epithelium survives the transformation, and quality control measures are implemented at each stage to verify epithelial integrity is maintained throughout formulation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The dehydration process uses carefully controlled parameters (temperature, humidity, time) that achieve composition stability without exceeding thresholds that would damage the epithelium. The micronization process similarly uses optimized mechanical stress levels that reduce particle size while preserving the delicate epithelial structures within the particles.

Inventive Principle:
Principle #35Parameter changes
