Solution Overview

Problem

Current therapies for kidney diseases, particularly end-stage renal disease, are invasive and costly, with stem cell collection methods posing significant risks, and there is a need for a less invasive and effective method to collect and utilize podocyte progenitor cells for kidney regeneration.

Innovation Solution

A method involving the collection, isolation, and culturing of podocyte progenitor cells and neural stem/progenitor cells from urine specimens, which includes centrifugation, cell marker expression analysis, and in vitro growth, followed by implantation into the kidney or central nervous system for treatment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If bone marrow cells are used as a source of stem cells, then stem cell therapy can be provided, but the procedure becomes invasive with significant risks

Engineering Contradiction:
Improvestem cell therapy effectivenessVSAvoidinvasiveness and risks
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the useful stem cell function from the harmful bone marrow collection procedure by identifying and isolating podocyte progenitor cells that naturally circulate in urine. This allows obtaining stem cells without the invasive bone marrow puncture procedure, thereby maintaining therapeutic effectiveness while eliminating the harmful invasive aspect.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses urine as an intermediary medium to access stem cells. Instead of directly accessing bone marrow, the method collects stem cells that are naturally excreted in urine, using the urinary system as an intermediary pathway to obtain therapeutic cells without invasive procedures.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If traditional stem cell collection methods are used, then stem cells can be obtained, but the procedure is invasive and carries significant risks

Engineering Contradiction:
Improvestem cell availabilityVSAvoidcollection procedure simplicity
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent employs a self-service approach where the patient's own body naturally excretes stem cells in urine, which can be collected without medical intervention. This eliminates the need for invasive collection procedures while maintaining adequate stem cell availability for therapy.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The method extracts stem cells from urine, a readily accessible bodily fluid, rather than requiring invasive procedures. This provides sufficient stem cell quantity through a simple urine collection process that any patient can perform.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If invasive procedures are used to collect stem cells, then stem cell therapy can proceed, but patient burden and healthcare costs increase

Engineering Contradiction:
Improvetherapy effectivenessVSAvoidtreatment procedure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the essential therapeutic element (stem cells) from a complex invasive procedure by obtaining them directly from urine. This simplifies the entire treatment pathway from collection to therapy while maintaining effectiveness, reducing both procedural complexity and associated costs.

Inventive Principle:
Principle #2Taking out (Extraction)
