Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing superposed unit dose automatic dishwashing detergent pouches face challenges in incorporating a sufficient amount of chemistry while maintaining ease of use and ensuring proper performance, with the size and dimensions of the pouch impacting dissolution rate and release from the dispenser drawer.
Innovation Solution
A superposed multi-sectioned water-soluble unit dose automatic dishwashing detergent pouch with specific dimensions and configurations, comprising a first section with one or more internal compartments and a second section with one or more internal compartments, each section having defined dimensions and containing different components, such as a powder and liquid, to enhance formulation strategies and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If more chemistry is incorporated into the pouch, then improved formulation strategies and performance are achieved, but the size and dimensions of the pouch increase, impacting dissolution rate and release from the dispenser drawer
Solution Approach 1:
The pouch is divided into multiple sections (first section and second section) with different internal compartment configurations. This segmentation allows different detergent components to be organized in separate compartments, enabling optimized volume distribution that balances chemistry content with controlled dissolution rate and dispenser drawer release performance.
Solution Approach 2:
The patent employs a superposed configuration where the first section is superposed onto the second section, creating a multi-dimensional arrangement. This vertical stacking approach allows increased chemistry volume without proportionally increasing the horizontal footprint, thereby maintaining dissolution rate and dispenser compatibility while incorporating more detergent composition.
2Quantity of substance
If the pouch size and dimensions are increased, then improved formulation strategies and performance are achieved, but ease of use and stability are compromised
Solution Approach 1:
By segmenting the pouch into multiple sections with specific dimension ranges (first section: major axis 42-90mm, minor axis 30-54mm, height 10-39mm; second section: height 2-31mm), the design maintains manageable size while accommodating increased detergent volume. Each section's dimensions are optimized for ease of handling and stability in the dispenser drawer.
Solution Approach 2:
The patent specifies precise parameter ranges for the pouch dimensions and internal compartment volumes to optimize the balance between detergent composition volume and ease of use. The total internal compartment volume is controlled within 18-199ml, with specific allocations to each section, ensuring the pouch remains easy to use while incorporating sufficient chemistry for improved performance.
3Quantity of substance
If the pouch size and dimensions are increased, then improved formulation strategies are achieved, but dissolution rate and release from dispenser drawer are impacted
Solution Approach 1:
The pouch is segmented into multiple sections with controlled internal compartment volumes. This segmentation creates multiple dissolution interfaces and controlled release zones, allowing the detergent composition to dissolve at an optimized rate while maintaining sufficient total volume for improved formulation strategies. The specific dimension ranges ensure appropriate surface area to volume ratios for controlled dissolution.
Solution Approach 2:
The superposed configuration creates a vertical arrangement that optimizes the surface area to volume ratio. By stacking sections vertically rather than expanding horizontally, the design maintains a compact footprint while providing sufficient internal volume. This dimensional arrangement facilitates controlled dissolution rate and ensures proper release from the dispenser drawer mechanism.
