Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern dishwashing detergents struggle to maintain high cleaning performance on stubborn stains at lower washing temperatures, leading to consumer dissatisfaction and increased water and energy consumption due to pre-treatment of stains.
Innovation Solution
A hand dishwashing detergent containing a specific combination of amylase and protease, where the amylase has an amino acid sequence identical to SEQ ID NO:1 and the protease has an amino acid sequence identical to SEQ ID NO:3, synergistically improves cleaning performance on enzyme-sensitive soils, particularly at lower temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If lower washing temperatures are used, then energy consumption is reduced, but cleaning performance on stubborn stains deteriorates
Solution Approach 1:
The patent changes the chemical parameters of the cleaning system by introducing specific enzyme combinations (amylase with specific activity ≥4000 U/mg and protease with specific activity ≥2000 U/mg) that maintain cleaning effectiveness at lower temperatures. This allows the washing process to operate at reduced temperatures while preserving cleaning performance through optimized enzymatic activity parameters.
Solution Approach 2:
The invention uses a composite enzymatic system combining multiple enzymes (amylase and protease with specific activity ratios) to achieve enhanced cleaning performance at low temperatures. This composite approach leverages the synergistic effects of different enzymes targeting various stain components, maintaining reliability while reducing energy input.
2Use of energy by stationary object
If conventional detergents are used at lower temperatures, then energy consumption is reduced, but cleaning performance on enzyme-sensitive soils deteriorates
Solution Approach 1:
The patent optimizes the enzymatic parameters by selecting amylase with specific activity ≥4000 U/mg and protease with specific activity ≥2000 U/mg, creating a chemically optimized system that maintains high cleaning performance on enzyme-sensitive soils at lower temperatures without requiring conventional high-temperature processing.
3Use of energy by moving object
If washing temperature is reduced, then energy consumption and water heating requirements are reduced, but cleaning effectiveness on stubborn soiling deteriorates
Solution Approach 1:
The invention changes the chemical action parameters by employing enzymes with optimized specific activities that function effectively at lower temperatures. The amylase (≥4000 U/mg) and protease (≥2000 U/mg) maintain catalytic efficiency at reduced temperatures, enabling effective removal of stubborn soiling without the need for high water heating energy input.
