Solution Overview

Problem

Current technologies lack effective methods to probe and understand the biological mechanisms underlying non-communicable diseases such as Type 2 diabetes, hypertension, and chronic kidney disease, limiting early diagnosis and treatment to symptom management.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional diagnostic methods are used, then symptom management is possible, but early diagnosis and treatment of non-communicable diseases cannot be achieved

Engineering Contradiction:

Improvedisease detection capabilityVSAvoiddiagnosis timing

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent changes the physical-chemical parameters of the diagnostic approach by using nanoparticle probes with specific surface properties (charge, hydrophobicity, ligand density) that interact with glycocalyx variations. This enables detection of subtle cellular changes associated with non-communicable diseases before symptoms manifest, achieving early diagnosis through parameter-based differentiation rather than conventional symptom-based methods

Inventive Principle:

Principle #35Parameter changes

2Strength

If nanoparticle probes with high affinity binding are used, then strong binding to target cells is achieved, but reversibility and controlled targeting are compromised

Engineering Contradiction:

Improvebinding strengthVSAvoidbinding reversibility

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by designing nanoparticle probes whose binding characteristics are not fixed but can be modulated. The probes exhibit dynamic binding behavior where affinity can be adjusted through surface functionalization, allowing the system to transition between strong binding (for stable targeting) and reversible binding (for controlled release and retargeting), thus achieving both strength and adaptability

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The binding parameters of the nanoparticle probes are optimized through controlled surface functionalization, where ligand density, molecular weight, and surface charge are precisely adjusted. This parameter control enables tuning of binding strength and reversibility to match specific diagnostic and therapeutic requirements, resolving the contradiction between strong binding and adaptability

Inventive Principle:

Principle #35Parameter changes

3Measurement precision

If nanoparticle probes target based on glycocalyx thickness variations, then disease-specific targeting is achieved, but complexity of probe design and characterization increases

Engineering Contradiction:

Improvecell differentiation accuracyVSAvoidprobe structure complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies local quality by functionalizing specific regions of the nanoparticle surface with different ligands or properties. This localized functionalization allows the probes to interact with specific glycocalyx components in a controlled manner, enabling precise differentiation of cells based on glycocalyx thickness without requiring complex overall probe structures

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The nanoparticle probes are designed with universal core structures that can be adapted for different applications through surface functionalization. This multi-functionality approach allows a single probe platform to target various cell types and disease states by simply changing surface ligands, reducing overall system complexity while maintaining high differentiation accuracy

Inventive Principle:

Principle #6Universality (Multi-functionality)
