Detergent Portion Segmentation for Solubility and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detergents, particularly liquid forms, face challenges in providing both effective cleaning performance and attractive appearance, with solid forms lacking in visual appeal and liquid forms requiring preservatives, while single-use portions in water-soluble pouches are gaining popularity for their convenience and aesthetics but struggle to combine these benefits.
Innovation Solution
A detergent or cleaning agent portion comprising a water-soluble wrapping with a continuous circumferential sealing seam, featuring a granular mixture of a solid composition as a free-flowing powdered phase combined with a dimensionally stable polyvinyl alcohol and polyethylene glycol phase, allowing for improved solubility, storage stability, and visual appeal through texture and color differentiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If liquid detergent format is used, then quick solubility and quick availability of active ingredients are improved, but preservatives are required and visual appearance is less attractive
Solution Approach 1:
The detergent is divided into multiple discrete phases (liquid phase and granular solid phase) within a single-use pouch, allowing each phase to maintain its inherent advantages while being contained together. The liquid phase provides quick solubility without requiring bulk preservatives for long-term storage stability.
Solution Approach 2:
The invention combines liquid detergent components with granular solid components in a composite formulation. This composite structure allows the liquid phase to dissolve quickly while the granular phase provides stability, eliminating the need for preservatives while maintaining visual appeal through phase differentiation.
2Object-generated harmful factors
If solid tablet format is used, then preservatives are not required, but solubility speed and visual appearance are reduced
Solution Approach 1:
The tablet is segmented into multiple phases including a liquid phase and granular solid phase. This segmentation allows the liquid components to dissolve rapidly while the granular components provide structural integrity and visual appeal, achieving both preservative-free formulation and quick solubility.
Solution Approach 2:
The invention changes the physical parameters of the solid phase by using granular material instead of compressed tablet form. This parameter change increases surface area and porosity, significantly improving solubility speed while maintaining the preservative-free advantage of solid formats.
3Ease of operation
If compressed tablet format is used, then dosing is convenient, but visual appearance and solubility are compromised
Solution Approach 1:
The detergent portion is segmented into distinct liquid and granular phases within a single-use pouch, maintaining dosing convenience while dramatically improving solubility. The pre-portioned pouch ensures accurate dosing, while the granular-liquid composition enables rapid dissolution.
Solution Approach 2:
The invention changes the physical state parameters from compressed solid to a combination of liquid and granular phases. This parameter change maintains the convenience of pre-portioned dosing while achieving superior solubility through the liquid component and enhanced surface area of granular particles.
4Shape
If granular mixture with different particles and colors is used, then visual appearance is improved, but manufacturing complexity increases
Solution Approach 1:
The detergent is segmented into distinct phases with different visual characteristics (liquid phase and granular phase with varying particle sizes and colors). This segmentation creates an attractive visual appearance while simplifying manufacturing, as each phase can be prepared separately and combined without requiring complex mixing processes.
