Water-Repellent Envelope Detergent for Wet Laundry Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing envelope-type detergent dissolves at low temperatures when wet, leading to instability and inconvenience in storing laundry, and users struggle to accurately measure detergent amounts due to variable laundry loads.
Innovation Solution
Incorporating a water-repellent component, such as fluorine-based or silicone-based compounds, into the detergent's water-soluble film to enhance water resistance and stability, allowing for improved shape retention and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a water-soluble polymer film structure is used for manufacturing the envelope-type detergent, then the detergent can dissolve and wash the laundry effectively, but the detergent bag loses shape stability when wetted by water during storage
Solution Approach 1:
The patent applies different properties to different parts of the film structure by incorporating water-repellent components (fluorine-based or silicone-based compounds) into the water-soluble polymer film. This creates a dual-function film where certain regions maintain water repellency for shape stability during storage, while other regions remain water-soluble for effective dissolution during washing.
Solution Approach 2:
The patent creates a composite film structure by combining water-soluble polymer materials with water-repellent additives (fluorine-based compounds, silicone-based compounds, or their mixtures). This composite material exhibits both water solubility for detergent function and water repellency for shape stability during storage, resolving the contradiction between these two opposing requirements.
2Reliability
If the envelope-type detergent is made fully water-soluble for effective washing, then the detergent dissolves well during washing, but it dissolves prematurely at low temperatures during storage causing instability
Solution Approach 1:
The patent modifies the chemical parameters of the film material by adding water-repellent components (fluorine-based compounds, silicone-based compounds) to the water-soluble polymer. This parameter change raises the water resistance threshold, allowing the film to maintain stability at low temperatures during storage while still dissolving effectively at higher washing temperatures.
3Volume of stationary object
If users store laundry in piles before washing to save space and costs, then space utilization improves, but the laundry accumulates odor and causes discomfort during the classifying process
Solution Approach 1:
The patent extracts the washing function from a centralized batch process and distributes it to individual items through pre-packaged envelope-type detergents. Each envelope contains a precise amount of detergent, allowing users to wash smaller batches more frequently, thereby preventing odor accumulation while maintaining space efficiency.
Solution Approach 2:
The patent prepares detergent in individual envelope packages in advance, with each envelope containing the exact amount needed for a specific load. This preliminary preparation eliminates the need to store large piles of untreated laundry, as users can immediately process smaller batches using the pre-measured detergent envelopes.
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 water-repellent envelope-type detergent maintains shape stability even with wet laundry, facilitating convenient storage and enabling accurate detergent quantification through various envelope sizes.
Implementation Method 1
the fluorine-based compound and/or the silicone-based compound is applied alone or as a mixture of two or more thereof in the water-soluble film constituting the envelope-type detergent, or a method of adding them during mixing raw materials of detergent compositions is applied so as to exhibit a water-repellent effect upon forming a polymer film
