Stabilized Antimicrobial Composition Using Segmented Water-Soluble Packets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current antimicrobial compositions for hospital surfaces are cumbersome and have varying results in effectively eliminating microorganisms, with existing products often losing efficacy quickly and having short shelf lives due to instability issues.
Innovation Solution
The development of stabilized antimicrobial compositions containing quaternary ammonium salts, trichloromelamine, and urea, packaged in dry, premeasured water-soluble packets to ensure accurate dosing and extended shelf life, providing improved stability and safety for workers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If liquid form antimicrobial compositions are used, then ease of operation is improved, but product stability deteriorates with shelf life of less than one month
Solution Approach 1:
The patent changes the physical state of the composition from liquid to dry powder form. This parameter change allows the composition to be stored stably for extended periods (over one month) while maintaining ease of operation through water-soluble packet formulation that dissolves readily in water for application.
Solution Approach 2:
The composition is segmented into water-soluble packets containing dry powder. This segmentation allows stable storage of the dry powder while providing convenient dosing and application by simply dissolving the packet contents in water, thus resolving the contradiction between stability and ease of operation.
2Manufacturing precision
If premeasured dosing is implemented, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The composition is divided into premeasured individual packets, each containing a precise amount of active ingredients. This segmentation achieves accurate dosing (manufacturing precision) while keeping the packaging system simple - merely requiring water-soluble packets without complex dosing mechanisms.
Solution Approach 2:
The patent uses disposable premeasured packets that are discarded after single use. This approach ensures precise dosing for each application while avoiding the need for complex reusable dosing devices, thus improving manufacturing precision without significantly increasing device complexity.
