Solution Overview

Problem

The evolution of antibiotic-resistant pathogenic bacteria has necessitated the search for alternative antimicrobial agents, and existing antimicrobial compounds from natural sources have limitations in effectiveness against various bacterial strains and fungi.

Innovation Solution

An antimicrobial composition is derived from the marine copepod Calanus finmarchicus, involving a process that includes purification, isolation, and concentration of non-proteinaceous and non-nucleic acid compounds, which are then used to treat microbial infections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing antimicrobial compounds from natural sources are used, then antimicrobial activity is achieved, but effectiveness against antibiotic-resistant pathogens is limited

Engineering Contradiction:
Improveantimicrobial effectivenessVSAvoidbroad-spectrum activity
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The invention extracts and utilizes multiple different antimicrobial compounds (including peptides, proteins, and small molecules) from the copepod Calanus finmarchicus to create a composition that exhibits broad-spectrum activity against diverse bacterial and fungal strains, including antibiotic-resistant pathogens. This multi-component approach provides universal antimicrobial protection rather than targeting specific pathogens.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The antimicrobial composition comprises a complex mixture of various compounds extracted from the copepod, including antimicrobial peptides, proteins, and small molecules. This composite composition synergistically combines multiple antimicrobial agents to achieve enhanced and broad-spectrum effectiveness against resistant pathogens.

Inventive Principle:
Principle #40Composite materials

2Manufacturing precision

If purification and isolation processes are applied to obtain non-proteinaceous antimicrobial compounds, then composition purity is improved, but processing complexity increases

Engineering Contradiction:
Improvecomposition purityVSAvoidprocessing steps
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The purification process is divided into multiple sequential steps: initial extraction of compounds from copepod material, followed by fractionation to separate different compound classes, then further purification steps to isolate non-proteinaceous antimicrobial compounds. This segmented approach achieves high purity while making the complex process more manageable and systematic.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention specifically extracts and isolates non-proteinaceous antimicrobial compounds (small molecules and metabolites) from the copepod material, separating them from proteinaceous components. This extraction focus simplifies the overall process by targeting specific compound classes with known stability and antimicrobial properties.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If conventional antibiotics are used to treat microbial infections, then treatment effectiveness is achieved, but antibiotic resistance develops

Engineering Contradiction:
Improveinfection treatment effectivenessVSAvoidantibiotic resistance
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The invention converts the copepod's natural defense mechanism (production of antimicrobial compounds for self-protection) into a beneficial treatment for human infections. The same compounds that protect the copepod from microbial attacks are extracted and used to treat antibiotic-resistant infections in humans, effectively converting a natural survival mechanism into a medical solution.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The invention utilizes naturally occurring, renewable antimicrobial compounds from a sustainable marine source (copepods) rather than relying on synthetic antibiotics that face resistance issues. These natural compounds can be replenished through sustainable harvesting of copepod populations, providing a renewable alternative to depleting antibiotic effectiveness.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
