Solution Overview

Problem

Current treatments for chlamydia infection are not effective for prolonged administration due to side effects and persistent infection challenges posed by intracellular parasites, and existing methods do not adequately address the risk of infertility and increased abortion/premature birth associated with the infection.

Innovation Solution

An oral agent containing dead or pulverized Lactobacillus casei cells is administered to prevent and treat chlamydia infection, improving fertility rates by reducing Chlamydia bacteria counts and preventing infertility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If antibacterial agents are administered to treat chlamydia infection, then bacterial infection is suppressed, but persistent infection occurs and side effects prevent prolonged administration

Engineering Contradiction:
Improveinfection suppression efficacyVSAvoidside effects and persistent infection
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces Lactobacillus casei as an intermediary organism that indirectly combats Chlamydia infection. Instead of directly killing Chlamydia with antibacterial agents, the probiotic Lactobacillus casei restores vaginal flora balance, creates an unfavorable environment for Chlamydia, and enhances immune response, thereby eliminating the need for prolonged antibacterial agent administration and avoiding its side effects

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the treatment approach from direct antibacterial action to probiotic-mediated ecological restoration. By administering Lactobacillus casei, the vaginal environment parameters (flora composition, pH balance, immune status) are modified to naturally suppress Chlamydia, allowing for safe prolonged administration without the harmful effects of continuous antibacterial therapy

Inventive Principle:
Principle #35Parameter changes

2Duration of action of moving object

If prolonged administration is used to completely eliminate Chlamydia, then infection is thoroughly treated, but side effects from continuous antibacterial agent use increase

Engineering Contradiction:
Improvetreatment durationVSAvoidside effects
Core Design Contradiction:
Duration of action of moving objectVSObject-affected harmful factors

Solution Approach 1:

Lactobacillus casei serves as a safe intermediary that can be administered prolongedly without the side effects associated with antibacterial agents. The probiotic continuously maintains vaginal flora balance and immune support over extended periods, enabling long-term treatment duration necessary for complete Chlamydia elimination while avoiding harmful side effects

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces long-term antibacterial agent therapy with prolonged probiotic administration. Lactobacillus casei, being a beneficial organism rather than a pharmacological agent, can be safely administered continuously without accumulating toxicity or causing resistance, effectively serving as a safe long-term treatment solution

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

3Ease of operation

If chlamydia infection is left untreated due to lack of symptoms, then patients avoid medical treatment, but infertility risk and transmission to others increase

Engineering Contradiction:
Improvetreatment accessibilityVSAvoidinfertility risk and infection spread
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent employs Lactobacillus casei that can be self-administered through oral supplementation, allowing individuals to restore their own vaginal flora balance without requiring medical procedures or prescriptions. This self-service approach makes treatment highly accessible while effectively reducing infertility risk and preventing infection spread through restored immune defense

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Lactobacillus casei provides multiple functions simultaneously: it restores vaginal flora balance, creates an unfavorable environment for Chlamydia, enhances immune response, and prevents both infertility and infection transmission. This multi-functional probiotic approach addresses multiple harmful outcomes through a single accessible intervention

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