Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for cartilage regeneration, such as surgical procedures and cell-based therapies, often result in low durability and insufficient regeneration into cartilage tissue, with challenges like scarring, fibrocartilage formation, and issues with cell differentiation and survival.

Innovation Solution

A peptide with an amino acid sequence of SEQ ID NO: 1 or SEQ ID NO: 2, engineered for enhanced stability and specificity, is used to induce production of glycosaminoglycan, COL2A1, COMP, COL11A, PCP, and aggrecan, promoting cartilage regeneration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If surgical procedures such as artificial joints, articular cartilage resurfacing, and microfracture are performed, then cartilage damage can be treated, but scars are left due to incisions and regeneration is into fibrocartilage with low durability

Engineering Contradiction:

Improvedurability of regenerated cartilageVSAvoidscarring and fibrocartilage formation

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent introduces a peptide compound as an intermediary substance that mediates between the surgical treatment and the cartilage regeneration process. This peptide acts as a biological modulator that guides the regeneration pathway toward native cartilage formation rather than fibrocartilage, thereby improving durability while reducing scarring effects

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the biological parameters of the regeneration environment by administering a specific peptide compound. This chemical parameter modification influences the differentiation of progenitor cells and the synthesis of extracellular matrix components, resulting in high-quality cartilage regeneration instead of fibrocartilage formation

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If intra-articular injectable solutions or hydrogels are used, then surgical procedure is simplified and quick therapeutic effects are achieved, but temporary pain relief is provided without sufficient induction of cartilage tissue regeneration

Engineering Contradiction:

Improvesimplicity of surgical procedureVSAvoidcartilage tissue regeneration

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent extends the useful action from temporary pain relief to continuous cartilage regeneration. The peptide compound maintains its biological activity over time, continuously promoting chondrocyte differentiation and extracellular matrix production, thereby transforming the treatment from a temporary measure to a regenerative process

Inventive Principle:

Principle #20Continuity of useful action

3Reliability

If autologous chondrocyte treatment is performed, then cartilage regeneration can be induced, but limitations exist when damaged area is large and treatment uses only cells collected and cultured from the patient

Engineering Contradiction:

Improvecartilage regenerationVSAvoidtreatment applicability to large damaged areas

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent extracts the essential regenerative function from whole cell-based therapy and isolates it into a peptide compound. This extraction allows the regenerative activity to be delivered in a concentrated, stable form that can be administered systemically, overcoming the limitations of autologous chondrocyte therapy for large damaged areas

Inventive Principle:

Principle #2Taking out (Extraction)

4Reliability

If stem cell treatment is performed, then cartilage regeneration can be induced, but issues arise such as differences in cell number and differentiation potential depending on collection area, changes in cell phenotype due to cell dedifferentiation during in vitro culture, and low differentiation rate into chondrocytes after in vivo transplantation

Engineering Contradiction:

Improvecartilage regenerationVSAvoidcell differentiation control

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The patent replaces the complex biological system of stem cell culture and differentiation control with a chemical system - a peptide compound that directly promotes cartilage regeneration. This substitution eliminates the variability and instability inherent in cell-based approaches, providing more precise and reliable treatment outcomes

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
