Laundry Detergent Sheet Manufacturing System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry detergents, whether in powder or liquid form, are inconvenient and inefficient, often resulting in wasted time measuring the correct amount for each load, and their packaging can lead to moisture issues, scattering, and environmental concerns.
Innovation Solution
A method and system for producing eco-friendly laundry detergent sheets using a composition of native corn starch, glycerin, polyvinyl alcohol, and other surfactants, which are mixed and processed into sheets, then packaged in compostable cellulose film and cardboard boxes, eliminating the need for external temperature control and minimizing waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid or powder laundry detergent is packaged in conventional containers, then the detergent can be stored and transported, but the packaging requires opening and closing operations that cause moisture ingress, lumping, and loss of cleaning power
Solution Approach 1:
The detergent is divided into individual unit-dose packets, each hermetically sealed independently. This segmentation allows each packet to remain sealed until use, eliminating the repeated opening and closing of a single large container that causes moisture ingress and lumping.
Solution Approach 2:
The detergent formulation is changed from conventional liquid or powder forms to a gel-based concentrated formula that can be hermetically sealed in thin-film packets. This parameter change enables the detergent to maintain stability and solvability while being packaged in a way that prevents moisture ingress.
2Reliability
If conventional detergent packaging is used, then detergent can be stored, but washing liquid automatically overflows from bottles due to repeated pushing
Solution Approach 1:
The detergent is packaged in individual unit-dose packets that are hermetically sealed. Each packet contains a precise amount of detergent and cannot overflow, eliminating the problem of liquid spilling from repeatedly opened and closed bottles.
Solution Approach 2:
The invention uses disposable hermetically sealed packets that are discarded after single use. This eliminates the need for reusable bottles that require opening and closing, thereby preventing overflow and contamination.
3Reliability
If washing powder is packaged in bags, then the detergent can be stored, but the powder scatters near the washstand while being taken and is challenging to clean
Solution Approach 1:
The detergent is packaged in individual unit-dose packets that contain the powder or gel in a sealed state. Users simply remove one packet at a time, eliminating the scattering of loose powder that occurs when opening and accessing bagged detergent.
Solution Approach 2:
The invention uses flexible thin-film hermetically sealed packets to contain the detergent. These packets are easy to handle and do not scatter contents, unlike open bags of powder detergent.
4Reliability
If conventional detergent packaging is used, then detergent can be transported, but plastic packaging creates environmental pollution and is not biodegradable
Solution Approach 1:
The packaging material is changed from conventional plastic to biodegradable and compostable thin-film materials. This parameter change maintains the protective and hermetic sealing functions while eliminating the environmental pollution associated with plastic waste.
Solution Approach 2:
The invention uses composite packaging materials that combine biodegradable polymers with functional coatings to achieve hermetic sealing and moisture barrier properties traditionally provided by plastic, but with environmental benefits.
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 detergent sheets are efficient, easy to use, and environmentally friendly, with stable cleaning performance, reduced water and energy consumption, and long-lasting preservation, while providing a plastic-free and biodegradable packaging solution.
Implementation Method 1
purifying water through a purifier that is installed on a tap
Implementation Method 2
pouring the mixture onto a hot belt to create a single flow of detergent that is cooked as the detergent progresses toward an end of a roller
Implementation Method 3
make a plurality of heat-sealed blisters from a compostable cellulose film

AI summary
A system, method, and composition for manufacturing sheets of laundry detergent includes purifying water through a purifier that is installed on a tap and collecting the water in a first production tank; preparing polyvinyl alcohol (PVA) in a second production tank; cooling the PVA and then transferring the PVA to a third production tank to prepare the composition for a mixture, then the mixture passes in a fourth production tank which is a mixer to complete the process; pouring a ready dough directly into the mixer where the ready dough is mixed worked until the production process is complete to obtain a mixture; receiving the mixture; pouring the mixture onto a hot belt to create a single flow of detergent that is cooked as the detergent progresses toward an end of a roller; and passing the detergent to a cutting bench where the sheets of laundry detergent are produced.
