Solution Overview

Problem

Current methods for inducing pluripotent stem cells often require the introduction of exogenous genetic materials or chemicals, which pose safety concerns and complexity, and do not efficiently differentiate cells into three germ layers without external stimulation.

Innovation Solution

A method involving the application of energy, such as ultrasound, lasers, or heat treatment, to differentiated cells mixed with a culture medium, forming spheroids that exhibit pluripotent characteristics without the need for reprogramming factors or chemicals, allowing for stable expression of undifferentiated markers and three germ layer markers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If exogenous genetic materials or chemicals are introduced to induce pluripotent stem cells, then reprogramming efficiency is improved, but safety and complexity deteriorate due to cancer risks and procedural complexity

Engineering Contradiction:
Improvereprogramming efficiencyVSAvoidsafety
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent removes exogenous genetic materials and chemicals from the reprogramming process, using only physical energy stimuli (ultrasound, laser, heat) to induce pluripotent stem cell formation. This extraction of harmful substances resolves the safety contradiction while maintaining reprogramming efficiency through alternative physical mechanisms.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces chemical and genetic reprogramming methods with physical energy fields (ultrasound waves, laser radiation, heat treatment). This substitution eliminates the need for exogenous materials while achieving similar or better reprogramming outcomes, thereby improving safety without sacrificing productivity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If exogenous genetic materials or chemicals are introduced to induce pluripotent stem cells, then reprogramming efficiency is improved, but device complexity deteriorates due to multiple components required

Engineering Contradiction:
Improvereprogramming efficiencyVSAvoidprocedure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the complex delivery systems, vectors, and chemical compounds required in traditional reprogramming methods. By using simple physical energy application (ultrasound, laser, or heat), the device complexity is dramatically reduced while maintaining high reprogramming efficiency.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent substitutes complex biochemical reprogramming systems with simple physical energy delivery systems. This replacement reduces device complexity from multiple interconnected components (vectors, chemicals, delivery mechanisms) to basic energy generation and delivery apparatus.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If traditional reprogramming methods are used, then pluripotent cells are formed, but differentiation into three germ layers is insufficient without external stimulation

Engineering Contradiction:
Improvepluripotent cell formationVSAvoiddifferentiation capability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent applies periodic or pulsed energy delivery (ultrasound pulses, laser pulses, or cyclic heat treatment) to simultaneously achieve pluripotent cell formation and enhance differentiation capability. The periodic nature of the energy application provides rhythmic stimulation that promotes both cell reprogramming and subsequent differentiation into three germ layers.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The patent changes physical parameters (energy intensity, frequency, duration, temperature) of the applied stimuli to control both pluripotent cell formation and differentiation. By optimizing these parameters, the system achieves dual functionality: generating pluripotent cells while simultaneously enhancing their differentiation potential into ectoderm, mesoderm, and endoderm.

Inventive Principle:
Principle #35Parameter changes
