Solution Overview

Problem

Bone grafting procedures often face challenges with excessive growth factor leakage, leading to a destabilized microenvironment and reduced efficacy in promoting bone growth, as surgeons struggle to visualize and control the distribution of growth factors during matrix application.

Innovation Solution

An osteogenic composition is developed that includes a growth factor, a coloring agent, and a biodegradable porous collagen matrix, where the coloring agent imparts a visible color to the growth factor, allowing surgeons to monitor its distribution and prevent excessive leakage, thereby maintaining the matrix's efficacy over time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If growth factor is applied to promote bone growth, then bone formation is enhanced, but excessive leakage occurs causing microenvironment destabilization and reduced efficacy

Engineering Contradiction:
Improvebone growth promotion efficacyVSAvoidgrowth factor leakage
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent applies color changes by incorporating a coloring agent into the growth factor composition. This allows the growth factor to be visually tracked during application and release, enabling surgeons to monitor distribution and detect excessive leakage. The color change principle transforms an invisible biochemical process into a visible indicator system that provides real-time feedback on growth factor behavior.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent implements feedback by using the colored growth factor composition as a visual monitoring system. The color provides immediate feedback to the surgeon about where the growth factor is located and how it is distributing, allowing real-time adjustment of the application process to prevent excessive leakage and maintain optimal concentrations at the target site.

Inventive Principle:
Principle #23Feedback

2Stability of the object's composition

If growth factor distribution is monitored to prevent leakage, then microenvironment stability is improved, but visualization capability is initially insufficient

Engineering Contradiction:
Improvemicroenvironment stabilityVSAvoidgrowth factor visualization
Core Design Contradiction:
Stability of the object's compositionVSDifficulty of detecting and measuring

Solution Approach 1:

The patent directly addresses the visualization difficulty by incorporating a coloring agent that imparts visible color to the growth factor composition. This transforms the invisible growth factor into a visually detectable substance, allowing surgeons to easily monitor its distribution, concentration, and leakage in real-time during the procedure without requiring complex imaging equipment.

Inventive Principle:
Principle #32Color changes

3Difficulty of detecting and measuring

If coloring agent is added to growth factor, then visualization of distribution is improved, but composition complexity increases

Engineering Contradiction:
Improvegrowth factor distribution visualizationVSAvoidcomposition complexity
Core Design Contradiction:
Difficulty of detecting and measuringVSDevice complexity

Solution Approach 1:

The patent applies color changes by incorporating a coloring agent into the growth factor composition. This allows the growth factor to be visually tracked during application and release, enabling surgeons to monitor distribution and detect excessive leakage. The color change principle transforms an invisible biochemical process into a visible indicator system that provides real-time feedback on growth factor behavior.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The coloring agent serves as an intermediary substance that does not directly participate in the bone growth process but facilitates visualization and monitoring. This intermediary enables the surgeon to track the growth factor without interfering with its biological function, providing a passive optical indicator that simplifies monitoring while maintaining the primary therapeutic mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)
