Solution Overview

Problem

Existing plasma radical solutions face challenges in maintaining sterilization and antibacterial effects due to instability of radicals, particularly peroxynitrite, which is difficult to synthesize and loses properties quickly when dissolved in solution.

Innovation Solution

A plasma radical solution is developed that generates and maintains peroxynitrite by adjusting pH and NO3- concentration using NaH2PO4, ensuring stability and effectiveness against bacteria, fungi, and viruses, with a solvent of distilled or purified water, and storage at 85° C or less.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If peroxynitrite is generated by dissolving plasma radicals in solution, then sterilization and antibacterial effects are achieved, but the radicals become unstable and lose their properties quickly

Engineering Contradiction:
Improvesterilization effectVSAvoidradical stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent applies preliminary action by adjusting the pH to weakly acidic conditions (pH 5-6) and adding phosphate buffer (NaH2PO4) before the radicals fully decompose. This pre-adjustment creates a stable environment that preserves peroxynitrite and other reactive species, extending their effective lifetime in solution while maintaining sterilization capability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent changes the pH parameter to weakly acidic conditions (pH 5-6) and controls the concentration of phosphate buffer to stabilize the radicals. By adjusting these parameters, the solution maintains peroxynitrite stability without sacrificing the sterilization effectiveness that requires certain levels of reactive oxygen and nitrogen species.

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If the pH and NO3- concentration are adjusted to maintain sterilization effects, then the solution stability improves, but the solution composition becomes more complex

Engineering Contradiction:
Improvesolution stabilityVSAvoidsolution composition complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent uses phosphate buffer (NaH2PO4) as an intermediary substance that mediates between the unstable radicals and the solution environment. The buffer captures excess protons and stabilizes the pH, indirectly protecting the peroxynitrite from decomposition while adding only a single, well-characterized chemical component to the solution.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If peroxynitrite is synthesized naturally in solution, then the solution can be prepared simply, but peroxynitrite is difficult to synthesize and maintain

Engineering Contradiction:
Improvesolution preparation easeVSAvoidperoxynitrite maintenance
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent performs preliminary pH adjustment and phosphate buffer addition before the radicals fully decompose, creating optimal conditions for peroxynitrite stabilization. This pre-preparation step is simple to execute and ensures that when peroxynitrite forms from plasma radical dissolution, it remains stable in solution rather than rapidly decomposing.

Inventive Principle:
Principle #10Preliminary action
