Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing treatments for infections caused by Tropheryma whipplei, Salmonella, Mycobacterium, and Mycobacterium bovis bacillus are often ineffective and require high doses, leading to unnecessary side effects due to the immune system's insufficient activation.

Innovation Solution

Applying alternating electric fields (similar to TTFields) to shift macrophage phenotype from M0 or M2 to M1, enhancing the immune response, followed by administering a therapeutically effective dose of antibiotics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If standard antibiotic treatment is administered without immune activation, then treatment can be given, but the immune system is insufficiently activated leading to ineffective treatment and high doses are required

Engineering Contradiction:

Improvetreatment effectivenessVSAvoiddrug dose

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies alternating electric fields to skew macrophage phenotype toward M1 before antibiotic administration. This preliminary immune activation prepares the immune system to work more effectively with the antibiotics, thereby improving treatment reliability and potentially allowing for lower drug doses.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent changes the phenotypic parameters of macrophages from M0/M2 to M1 phenotype through application of alternating electric fields. This parameter change in immune cell characteristics enhances the overall immune response and improves the effectiveness of subsequent antibiotic treatment.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If high doses of antibiotics are administered to ensure treatment effectiveness, then treatment reliability improves, but unnecessary side effects occur

Engineering Contradiction:

Improvetreatment effectivenessVSAvoidside effects

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

By pre-activating the immune system with alternating electric fields to skew macrophages toward M1 phenotype, the body's natural defense mechanisms are enhanced before antibiotic administration. This reduces the reliance on high doses of antibiotics, thereby minimizing side effects while maintaining treatment effectiveness.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent leverages the body's own immune system by skews macrophage phenotype to enhance self-defense capabilities. This self-service approach reduces the need for high external drug intervention, minimizing harmful side effects while maintaining effective treatment.

Inventive Principle:

Principle #25Self-service

3Reliability

If alternating electric fields are applied to skew macrophage phenotype, then immune response is enhanced and treatment effectiveness improves, but the treatment protocol becomes more complex

Engineering Contradiction:

Improvetreatment effectivenessVSAvoidtreatment protocol

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses alternating electric fields as an intermediary mechanism to skew macrophage phenotype. This physical field serves as a non-invasive mediator that can be applied topically through adhesive patches, simplifying the overall treatment protocol while achieving the desired immune modulation effect.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces complex pharmacological immune activation strategies with a physical field approach using alternating electric fields. This substitution simplifies the treatment protocol by using a well-understood physical mechanism rather than complex drug combinations or administration protocols.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
