Liquid Droplet Composition Outer Wall Layer Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid droplet-making compositions are prone to bursting upon contact with dry surfaces or due to moisture evaporation, resulting in a short lasting period.
Innovation Solution
A liquid droplet-making composition comprising 100 parts of water, 1 to 15 parts of surfactant, 60 to 110 parts of drying agent, 1.5 to 3 parts of cellulose ether, 5 to 70 parts of saccharide, and 0.01 to 10 parts of surfactant stabilizer, which forms an outer wall layer on liquid droplets, enhancing their retentivity and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If conventional liquid droplet-making composition (surfactant and glycerin) is used, then liquid droplets can be formed easily, but the lasting period is very short due to bursting by contact with dry surface or moisture evaporation
Solution Approach 1:
The patent uses a composite material system consisting of cellulose ether (hydrophilic polymer) and saccharide (hydrophobic agent) combined with surfactant. This composite approach creates an outer wall layer with balanced hydrophilic-hydrophobic properties that prevents both excessive water absorption and moisture evaporation, thereby extending the lasting period and improving reliability of liquid droplets
Solution Approach 2:
The patent optimizes specific parameter ranges: cellulose ether at 1.5-3 parts by weight, saccharide at 5-70 parts by weight, and drying agent at 60-110 parts by weight based on 100 parts of water. These parameter adjustments create the optimal outer wall layer structure that enhances droplet stability and longevity without causing bursting
2Duration of action of moving object
If drying agent is added to prevent moisture evaporation, then lasting period may be extended, but liquid droplets may burst upon contact with dry surface
Solution Approach 1:
The patent creates a localized protective outer wall layer on the surface of liquid droplets with specific hydrophobic properties. The saccharide component concentrates at the outer surface to provide water-repelling characteristics, while the bulk composition maintains appropriate hydrophilicity. This local quality differentiation allows the droplet surface to resist dry surface contact without causing bursting, while the interior maintains moisture balance for extended longevity
