Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry products face challenges in providing a convenient and effective combination of hydrophobic fabric conditioning agents and perfume, as hydrophobic components often interact in a way that reduces the deposition of silicone on fabrics, leading to inefficiencies in softening and scent distribution.
Innovation Solution
A composition comprising separate particles of water-soluble carriers with perfume and silicone, where the onset of melt for both types of particles is between 25°C to 120°C, allowing for stable packaging and controlled release during washing, ensuring efficient deposition of silicone and perfume on fabrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hydrophobic fabric conditioning agents and perfume are combined in a single product, then convenience is improved, but deposition efficiency deteriorates
Solution Approach 1:
The invention divides the laundry treatment composition into separate particles: first particles containing perfume and second particles containing silicone fabric conditioning agent. Each particle type maintains its own composition integrity, preventing premature interaction between hydrophobic components while enabling combined functionality when used together in a single washing cycle.
2Strength
If hydrophobic fabric conditioning agents are used, then fabric softness is improved, but product formulation difficulty increases
Solution Approach 1:
The formulation is segmented into separate particle systems where silicone fabric conditioning agents are encapsulated in second particles with water-soluble carriers. This segmentation allows each particle type to be formulated and optimized independently, simplifying the overall product development process while maintaining effective fabric softness.
Solution Approach 2:
The invention changes the physical state and delivery mechanism of hydrophobic silicone agents by encapsulating them in water-soluble carrier particles with controlled melt temperatures (25-120°C). This parameter change enables the hydrophobic agent to be delivered through a hydrophilic system, resolving formulation compatibility issues.
3Strength
If liquid fabric enhancers are used, then fabric softness and scent are improved, but user care requirements increase
Solution Approach 1:
The particulate composition is designed for self-service use: users simply pour the particles into the washing machine drum or dispenser, and the particles automatically dissolve and release their contents during the wash cycle. The water-soluble carriers self-dissolve without requiring user intervention, eliminating the careful pouring and positioning steps required for liquid fabric enhancers.
4Manufacturing precision
If separate particles with different melt temperatures are used, then deposition control is improved, but product complexity increases
Solution Approach 1:
The invention utilizes parameter changes in melt temperature (ranging from 25-120°C) of water-soluble carrier materials to control the release timing of perfume and silicone agents. By selecting carriers with appropriate melt points, the formulation achieves controlled deposition during different phases of the washing cycle without adding mechanical complexity.
