Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disinfectants have limited long-term effectiveness against a broad spectrum of pathogens, often requiring repeated applications and contain toxic compounds that are harmful to humans and the environment.
Innovation Solution
A composition comprising quaternary compounds, alcohols or polyols, inorganic or organic acids, and essential oils, which provides broad-spectrum antimicrobial activity with long-lasting protection for at least two days without using high concentrations of toxic quaternary ammonium compounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high concentrations of quaternary ammonium compounds are used to achieve broad-spectrum biocidal effect, then antimicrobial activity is improved, but toxicity to humans, animals and environment increases
Solution Approach 1:
The patent combines multiple quaternary compounds with different structures ( Formula I and Formula II) in specific low concentrations (0.05-2.0 wt% each), creating a synergistic mixture that achieves broad-spectrum biocidal effect without requiring high concentrations of single toxic compounds. The combination of different quaternary structures targets multiple microbial mechanisms simultaneously.
Solution Approach 2:
The invention creates a composite biocidal formulation containing multiple quaternary compounds (Formula I and Formula II), alcohols/polyols, and other auxiliary substances. This composite approach distributes the biocidal load across multiple components, reducing the toxic burden of any single compound while maintaining effective broad-spectrum activity.
2Adaptability or versatility
If additional differently structured quaternary organic ammonium compounds are added to achieve sufficient biocidal activity against entire microbial spectrum, then antimicrobial coverage is improved, but environmental and oral toxicity increases
Solution Approach 1:
The patent merges quaternary compounds with nitrogen (Formula I) and phosphorus (Formula II) in specific low concentrations (0.05-2.0 wt% each), creating a multi-target formulation that covers enveloped viruses, normal viruses, yeasts, moulds, spores, encapsulated spores, and all bacterial species without exceeding safe toxicity thresholds.
3Duration of action of stationary object
If quaternary organic ammonium compound formulations are used to provide long-term retarding biocidal activity, then duration of protection is improved, but repeated application frequency increases
Solution Approach 1:
The patent formulates a composition where multiple quaternary compounds and alcohols/polyols work continuously to maintain biocidal activity on surfaces. The synergistic interaction between components ensures sustained protection against microbial contamination, reducing the need for frequent reapplication while maintaining effective concentrations over time.
