Solution Overview

Problem

Current methods for removing viruses, bacteria, and microbial components from surfaces are inefficient due to resistance issues and the use of harmful chemicals, which can lead to incomplete eradication and promote antibiotic resistance, and existing devices fail to effectively retain these pathogens for analysis or disposal.

Innovation Solution

A device comprising a carbohydrate-based polymer carrier material with a covalently attached binding agent, such as lectins or glycoproteins, that can strongly bind and retain biotoxins, viruses, and microbes, including resistant forms, for effective removal and potential analysis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If strong chemical disinfectants or extreme heat are used to destroy microbes and viruses, then the eradication effectiveness is improved, but harmful substances remain and can be damaging to users

Engineering Contradiction:
Improveeradication effectivenessVSAvoidharmful substances remaining
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and removes the harmful microbial targets from surfaces using a carrier material that binds to them, separating the pathogens from the surface without requiring destructive chemicals or heat that would leave harmful residues

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The carrier material acts as an intermediary substance that binds to microbial targets through specific interactions (such as lectin-carbohydrate binding), enabling removal without direct contact with harmful chemicals or extreme conditions

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If conventional adsorption methods are used to retain removed targets, then the removal process is simple, but the retention is insufficient and targets may be released when encountering another surface

Engineering Contradiction:
Improvesimplicity of retention methodVSAvoidretention stability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent applies preliminary action by pre-treating the carrier material with binding agents (such as lectins or other specific binding molecules) before use, so that when the carrier contacts microbial targets, strong specific binding occurs immediately, preventing subsequent release

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses composite materials combining a carrier material (such as cellulose or other substrates) with specifically selected binding agents that have high affinity for microbial targets, creating a material that provides both ease of use and strong retention through the synergistic combination of the carrier and binding agent

Inventive Principle:
Principle #40Composite materials

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution enables stable and efficient removal and retention of pathogens from surfaces, reducing the risk of re-release and promoting safer, non-toxic decontamination while maintaining the integrity of pathogens for diagnostic purposes.

Implementation Method 1

The binding agent is attached by one or more covalent bonds to the carrier material

Methodology Applied
Scientific EffectCovalent bonding: Chemical Bonding

Implementation Method 2
