Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry processes at lower wash temperatures face challenges in fabric cleaning, care, and freshness due to impaired dissolution performance and reduced reaction kinetics, particularly with solid detergent products, and altered perfume release profiles.
Innovation Solution
A method of laundering fabric involves contacting a laundry detergent composition with water to form a wash liquor at temperatures between 0°C to 20°C, using a front-loading automatic washing machine with a specific detergent composition that includes catalytic ingredients, bleach catalysts, and other additives to maintain effective cleaning and freshness performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If wash temperature is lowered to improve environmental friendliness and energy efficiency, then energy consumption and environmental impact are reduced, but fabric cleaning performance, detergent dissolution, and reaction kinetics deteriorate
Solution Approach 1:
The patent changes the chemical parameters of the detergent composition by incorporating catalytic ingredients and specific detergent formulations that remain effective at low temperatures. This allows the washing process to operate at reduced temperatures while maintaining cleaning effectiveness, thus resolving the contradiction between energy savings and cleaning performance.
Solution Approach 2:
The patent introduces catalytic ingredients as intermediary substances that facilitate the cleaning process at low temperatures. These catalysts mediate between the low-temperature washing conditions and the requirement for effective fabric cleaning, enabling both energy efficiency and reliable cleaning performance to coexist.
2Object-affected harmful factors
If wash temperature is lowered to reduce environmental impact, then environmental friendliness improves, but detergent dissolution performance and reaction kinetics deteriorate
Solution Approach 1:
The patent modifies the detergent composition parameters by incorporating specific catalytic ingredients and formulations designed to dissolve effectively at low temperatures. This parameter change enables the detergent to maintain dissolution performance and reaction kinetics even under environmentally friendly low-temperature conditions.
3Loss of energy
If wash temperature is lowered to save energy, then energy efficiency improves, but fabric care profile and freshness profile deteriorate
Solution Approach 1:
The patent introduces specific detergent ingredients and catalytic components that act as intermediaries to protect fabric integrity and maintain freshness at low temperatures. These intermediaries enable the washing process to achieve both energy efficiency and reliable fabric care without requiring high temperatures.
