Multiphase Cleaning Agent Pouch With Liquid-Absorbing Particles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Solid detergents and cleaning agents exhibit high stickiness and poor flow properties, leading to poor dispensing and larger volume requirements for equivalent cleaning performance, limiting their compactness and processability.
Innovation Solution
A washing or cleaning agent portion comprising a chamber with a water-soluble coating and a particulate phase directly contacted by a liquid composition, allowing the liquid to be absorbed into the particulate phase, enhancing flowability and compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If solid detergent formulations with high surfactant content are used, then cleaning performance is improved, but flow properties and dispensing characteristics deteriorate
Solution Approach 1:
The detergent is divided into distinct solid particles (beads, granules, or tablets) with specific size ranges (0.1-5mm). This segmentation allows high surfactant content within each particle while maintaining overall flowability of the particulate mixture, resolving the contradiction between cleaning performance and dispensing characteristics.
Solution Approach 2:
The invention changes the physical state and size parameters of the detergent from conventional bulk solid formulations to controlled particulate forms with specific size distributions. This parameter change enables both high surfactant loading for improved cleaning and optimal flow properties for better dispensing.
2Reliability
If larger volumes are used to achieve equivalent cleaning performance, then cleaning effectiveness is maintained, but compactness and storage efficiency deteriorate
Solution Approach 1:
By changing the physical form to dense particulate structures with controlled size and morphology, the invention achieves higher cleaning performance per unit volume. The particulate form allows efficient packing and reduced volume while maintaining or improving cleaning effectiveness.
3Volume of moving object
If pre-portioned detergent portions are made more compact, then storage and handling are improved, but dosing precision and visual differentiation deteriorate
Solution Approach 1:
The detergent is portioned into discrete particles with controlled size ranges that enable both compact packing and precise dosing. The segmented structure allows individual particles to be accurately measured and dispensed while maintaining overall compactness of the portioned product.
Solution Approach 2:
The invention incorporates visually distinguishable particles that can be differentiated by color, shape, or other visual characteristics. This allows consumers to easily identify and dose the correct amount of detergent while maintaining compact portioning for storage and handling.
