Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Powdered laundry detergents face issues with dissolvability in cold water and messiness during measurement, and existing solid forms like tablets and sheets have limitations in performance and sustainability, particularly concerning environmental impact and pipe clogging due to undissolved materials.
Innovation Solution
A detergent composition comprising soda ash, an acid, a fatty alcohol ethoxylate, an anionic surfactant, a detergent polymer, and a binder, formulated as a powder without conventional fillers, which can be compressed into a tablet form that dissolves quickly in cold water, reducing environmental impact and improving aesthetics and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If powdered detergent is used, then it offers quick and easy laundry process with better efficacy, but it suffers from dissolvability issues in cold water and messiness while measuring
Solution Approach 1:
The detergent is formulated as pre-measured individual tablets, dividing the detergent into discrete units. Each tablet contains optimized concentrations of surfactants (10-25% anionic surfactant, 5-15% nonionic surfactant), soda ash (15-30%), and binders (5-15%), eliminating the need for user measurement while ensuring consistent dosing and improved dissolution characteristics.
Solution Approach 2:
The invention changes the physical and chemical parameters of the detergent formulation by using specific binder materials (sugars, starches, or polyols at 5-15% concentration) and controlling surfactant loading, which improves cold water dissolvability while maintaining cleaning efficacy. The tablet form factor and composition ratios are optimized parameters that enable both ease of use and effective dissolution.
2Ease of operation
If solid detergent forms like tablets and sheets are used, then pre-measured dosing is achieved, but performance is limited due to aesthetics, strength, and stability issues
Solution Approach 1:
The detergent tablet is formulated as a composite material system combining multiple components in specific ratios: anionic surfactants (10-25%), nonionic surfactants (5-15%), soda ash (15-30%), detergent polymers (1-5%), and binders (5-15%). This composite formulation ensures structural integrity for handling while maintaining stability and performance consistency across storage conditions.
3Quantity of substance
If conventional powdered detergent is used, then it provides cleaning performance, but undissolved materials can clog pipes and drains
Solution Approach 1:
The detergent is formulated to undergo complete phase transition from solid tablet to dissolved solution during the wash cycle. The binder system (sugars, starches, or polyols) and surfactant combination ensures complete dissolution of all components, including the 15-30% soda ash and 10-25% anionic surfactant, preventing any undissolved residue that could clog drainage systems.
4Productivity
If phosphates are used as additives in detergents, then cleaning performance is improved, but health problems and environmental hazards arise
Solution Approach 1:
The invention removes phosphates entirely from the detergent formulation, eliminating the harmful substance while maintaining cleaning performance through alternative components. The phosphate-free formula relies on optimized surfactant systems (anionic and nonionic), soda ash for water softening, and detergent polymers to achieve effective cleaning without environmental damage or health hazards.
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 provides a clear or semi-translucent solution upon dissolution, enhancing performance and stability, reducing the risk of pipe clogging, and offering improved handling and storage characteristics while being environmentally friendly by minimizing phosphate use.
