Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional detergents struggle to effectively remove peptidoglycan, a sticky bacterial cell wall component that causes redeposition of soils and malodor on textiles, particularly in low-temperature washing and biofilm environments.
Innovation Solution
A cleaning composition comprising a peptidoglycan degradation enzyme, anionic surfactants, and additional cleaning components like builders and bleach, which targets and breaks down peptidoglycan, enhancing soil removal and malodor reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional detergent compositions are used, then general cleaning is achieved, but peptidoglycan removal is insufficient leading to redeposition and malodor
Solution Approach 1:
The patent extracts and targets peptidoglycan specifically using peptidoglycan-degrading enzymes (lysozyme and transglycosylase) that selectively break down bacterial cell wall components, separating this function from general cleaning to address the specific problem of peptidoglycan-induced redeposition and malodor
Solution Approach 2:
The patent introduces peptidoglycan-degrading enzymes as intermediary substances that mediate between the detergent formulation and peptidoglycan substrates, enabling effective degradation of this recalcitrant component without compromising other cleaning functions
2Use of energy by stationary object
If low-temperature washing is used, then energy consumption is reduced, but peptidoglycan degradation is insufficient
Solution Approach 1:
The patent replaces thermal energy (heat) with enzymatic catalysis as the primary mechanism for peptidoglycan degradation, allowing effective breakdown at low temperatures through the action of lysozyme and transglycosylase enzymes rather than relying on thermal energy
Solution Approach 2:
The patent changes the degradation mechanism from thermal-driven to enzyme-driven by introducing specific catalytic proteins, enabling peptidoglycan breakdown at low temperatures where conventional thermal methods would be ineffective
3Object-generated harmful factors
If perfumes are added to mask malodor, then odor is temporarily covered, but the underlying cause is not addressed
Solution Approach 1:
The patent converts the harmful peptidoglycan substrates into beneficial cleaned surfaces by using peptidoglycan-degrading enzymes to彻底 remove the root cause of malodor, transforming the problem into a solution that provides long-term odor control rather than temporary masking
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition effectively reduces redeposition of soils and malodor on textiles by enzymatically degrading peptidoglycan, improving cleaning efficacy and freshness.
Implementation Method 1
a peptidoglycan degradation enzyme, wherein the polypeptide has peptidoglycan lyase activity and preferably N-acetylmuramyl-L-alanine amidase activity
