Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Detergent compositions face challenges with enzyme stability and high production costs due to limitations in enzyme solubility and the need for expensive formulation ingredients in liquid enzyme products, while granulates have high active enzyme content but are not efficient in uniform distribution.
Innovation Solution
An enzyme slurry composition comprising enzyme particles, water-soluble salts, viscosity regulating agents, and a carrier liquid, which maintains enzyme stability and uniform distribution, allowing for higher active enzyme content and reduced production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If liquid enzyme products are used, then enzyme solubility is improved, but formulation costs increase due to expensive ingredients needed to retain enzyme stability
Solution Approach 1:
The patent introduces a water-soluble salt as an intermediary substance that mediates between the enzyme particles and the aqueous carrier. The salt creates a stable slurry system without requiring expensive formulation ingredients, thus resolving the contradiction between maintaining enzyme stability and reducing formulation costs
Solution Approach 2:
The patent changes the physical state of the enzyme from dissolved (liquid) to suspended particulate form in a controlled slurry. By adjusting parameters such as particle size, salt concentration, and viscosity regulator content, the system achieves stability without the high costs associated with liquid enzyme formulations
2Quantity of substance
If granulate form is used, then active enzyme content is improved, but uniform distribution deteriorates
Solution Approach 1:
The patent segments the granulate form into smaller enzyme particles that are suspended in an aqueous slurry. This segmentation allows the high active enzyme content to be distributed uniformly throughout the liquid medium, combining the advantages of both granulate and liquid forms
Solution Approach 2:
The patent uses hydraulic principles by creating a liquid slurry suspension that flows and distributes uniformly. The aqueous carrier with appropriate viscosity ensures homogeneous distribution of enzyme particles, overcoming the distribution problems of granulate forms
3Productivity
If enzyme concentration is increased, then productivity is improved, but enzyme solubility limitations worsen
Solution Approach 1:
The patent utilizes phase transition by maintaining enzyme in a suspended particulate phase rather than dissolved phase. This allows high enzyme concentrations to be achieved while avoiding solubility limitations, as the enzymes remain as stable particles in the aqueous slurry
