Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current treatments for ocular and systemic infections, particularly viral conjunctivitis, are limited by narrow spectrum effectiveness, emerging resistance, and significant ocular toxicity, with no effective treatments available for viral conjunctivitis and other pathogens.

Innovation Solution

Development of sodium chlorite compositions activated in buffers with pH less than or equal to 5, combined with non-ionic surfactants, for broad-spectrum antimicrobial, antiviral, and antifungal activity, applied topically or via delivery devices to treat ocular and non-ocular infections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional antimicrobial treatments are used, then some pathogens are treated, but treatment spectrum is narrow and resistance emerges

Engineering Contradiction:

Improvetreatment spectrumVSAvoidresistance emergence

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies universality by formulating a broad-spectrum antimicrobial composition that effectively treats multiple types of pathogens including viruses, bacteria, fungi, and parasites simultaneously. The composition combines several active ingredients (chlorhexidine, povidone-iodine, hydrogen peroxide, and surfactants) to create a multi-functional solution that addresses diverse microbial threats with a single treatment, eliminating the need for multiple specialized treatments and reducing the risk of resistance development through multi-target action.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If potent antimicrobial agents are used, then infection efficacy is improved, but ocular toxicity increases

Engineering Contradiction:

Improveinfection treatment efficacyVSAvoidocular toxicity

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by carefully optimizing the concentration ranges and pH levels of each active ingredient to achieve maximum antimicrobial efficacy while minimizing ocular toxicity. The composition specifies precise concentration parameters for chlorox (0.01-0.1%), povidone-iodine (0.1-1%), hydrogen peroxide (0.1-1%), and surfactants (0.1-1%), along with pH adjustment to maintain physiological compatibility. This parameter optimization allows the use of potent antimicrobials while protecting ocular tissues from harmful effects.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent applies the intermediary principle by using surfactants (Tween 80, Brij 35, or Pluronic F-127) as mediators that enhance the penetration and distribution of active ingredients while reducing their direct toxic interaction with ocular tissues. These surfactants act as protective intermediaries that facilitate therapeutic action while mitigating harmful effects, allowing potent antimicrobials to work effectively without causing excessive ocular irritation or damage.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Speed

If rapid-onset antimicrobial agents are used, then infection control is improved, but application frequency must be increased

Engineering Contradiction:

Improveantimicrobial onset speedVSAvoidapplication frequency

Core Design Contradiction:

SpeedVSProductivity

Solution Approach 1:

The patent applies continuity of useful action by formulating a composition that maintains sustained antimicrobial activity over an extended period, allowing for less frequent applications. The combination of multiple active ingredients with different mechanisms of action and persistence characteristics creates a continuous therapeutic effect that persists throughout the day. The surfactants and pH buffers further stabilize the formulation to maintain consistent activity levels, reducing the need for frequent reapplication while ensuring continuous protection against infections.

Inventive Principle:

Principle #20Continuity of useful action

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 compositions provide effective treatment and prevention of infections with minimal ocular toxicity, suitable for frequent application, including ocular and respiratory uses, and are up to 50,000 times more effective than povidone-iodine as a rapid-onset antimicrobial agent.
