Multiphase Washing Agent Shaped Body Production via Segmented Injection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multiphase washing or cleaning agent dosing units face challenges in achieving good dissolution behavior, attractive product appearance, and appealing feel, while also being easy to store and transport under mechanical loads.
Innovation Solution
A method involving the use of an injector to introduce two free-flowing washing or cleaning agents into a mold, where one agent is solidified to form a multiphase shaped body with distinct phases, ensuring dimensional stability and aesthetic appeal, using a preferred embodiment where the agents are introduced through separate outlet openings in the injector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiphase dosing units are designed with separate phases for incompatible ingredients, then the functional performance and washing effect are improved, but the product appearance and feel may become less attractive
Solution Approach 1:
The washing agent is divided into multiple phases (e.g., hydrophobic and hydrophilic phases) that are spatially separated within the dosing unit. Each phase contains specific ingredients suited for different cleaning functions, allowing incompatible substances to coexist without premature interaction while maintaining distinct functional zones that dissolve separately during use
Solution Approach 2:
One phase is embedded within another phase structure, creating a nested configuration where inner phases are surrounded by outer phases. This nested arrangement allows multiple functional components to be integrated in a compact, aesthetically pleasing form factor while preserving phase separation and enabling sequential dissolution during the washing process
2Loss of time
If water-soluble multi-chamber pouches are used for packaging liquids or powders, then dissolution time is significantly shortened, but the packaging complexity and manufacturing difficulty increase
Solution Approach 1:
Water-soluble films are used as the pouch material, allowing the entire packaging structure to dissolve rapidly in water. The thin film design enables quick breakdown into the washing liquor, releasing the contained phases without requiring complex opening mechanisms or manual intervention, thereby significantly reducing dissolution time
Solution Approach 2:
Multiple chambers containing different phases are integrated into a single unified pouch structure. The separate phases are packaged together in one dissolvable container, allowing simultaneous dissolution of all chambers at once, which simplifies the overall packaging system while maintaining phase separation until use
3Ease of operation
If water-insoluble film is used for packaging dosing units, then handling is easier, but film seams may not be leakproof and product feel may be unpleasant
Solution Approach 1:
The packaging material transitions from water-insoluble to water-soluble film, fundamentally changing the material parameter. This change enables the film to dissolve completely in water, eliminating the need for leakproof seams and removing unpleasant tactile sensations, while the dissolvable nature provides inherent sealing through the continuous film structure
4Ease of manufacture
If multiphase tablets are produced by forming powdered premixes, then manufacturing is simplified, but dissolution behavior and product appearance are compromised
Solution Approach 1:
Instead of creating homogeneous powdered premixes, the washing agent is segmented into distinct phases that are separately contained within the dosing unit. This segmentation allows each phase to maintain its own dissolution characteristics, enabling controlled release patterns and improving overall dissolution behavior while preserving manufacturing simplicity through modular assembly

Implementation Method 1
introducing the first free-flowing washing or cleaning agent and the second free-flowing washing or cleaning agent, which is different from the first washing or cleaning agent, into a mold by means of the injector
Implementation Method 2
solidifying at least one of the free-flowing first and second washing or cleaning agents in the mold, thus forming a multiphase washing or cleaning agent shaped body
