Solution Overview

Problem

Current cultured meat production methods are inefficient, costly, and fail to replicate the texture and appearance of real meat, requiring animal slaughter for tissue collection and taking a long time to produce stem cells, which reduces cell yield and increases production costs.

Innovation Solution

A method involving the formation of organized muscle tissue through a self-organizing technique by coating cell sheets with a nanofilm using electrostatic, van der Waals, hydrophobic, hydrogen, or covalent bonding, and stacking them to improve mechanical properties and maintain cell-to-cell junctions, allowing for mass proliferation and differentiation without polymer supports.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional scaffold-based self-organizing methods are used to produce cultured meat, then muscle tissue can be formed, but the production time is long and cell yield is reduced

Engineering Contradiction:

Improvecell yieldVSAvoidproduction time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The invention extracts and removes the scaffold component from the traditional cultured meat production system. By using a scaffold-free self-organizing method where cells directly form muscle tissue without external support structures, the production process is simplified and accelerated, resolving the contradiction between productivity and production time.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention enables cells to self-organize and self-assemble into muscle tissue structures without external scaffolds. The cells autonomously form the necessary tissue architecture through their own biological mechanisms, eliminating the need for time-consuming scaffold integration and improving both cell yield and production efficiency.

Inventive Principle:

Principle #25Self-service

2Quantity of substance

If long-term cell culture is used to produce cultured meat, then sufficient cell quantity can be obtained, but proliferation and differentiation efficiency is reduced

Engineering Contradiction:

Improvecell quantityVSAvoidproliferation efficiency

Core Design Contradiction:

Quantity of substanceVSProductivity

Solution Approach 1:

The invention uses growth factors and optimization techniques in the preliminary stages of cell culture to accelerate proliferation and differentiation. By providing the right conditions early in the culture process, sufficient cell quantity is achieved more quickly, preventing the efficiency loss that occurs with extended culture periods.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If current cultured meat production methods are used, then meat can be produced without livestock, but the appearance and texture are significantly different from real meat

Engineering Contradiction:

Improvemeat production capabilityVSAvoidtexture and appearance quality

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The invention enables cells to self-organize into realistic muscle tissue structures that replicate the appearance and texture of real meat. Through scaffold-free self-organizing, the cells naturally form the complex three-dimensional architecture and tissue properties needed to match conventional meat, resolving the contradiction between production capability and product quality.

Inventive Principle:
