Apertured Film Wall Pouches Resolve Slow Dissolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pouches with film wall materials exhibit long Average Rupture Time and Dissolution Time, leading to incomplete dissolution, which results in remaining film material attaching to cleaned items and disposal issues, while also failing to effectively release active agents during use.
Innovation Solution
Development of pouches with apertured film wall materials that are water-soluble, designed to rupture quickly and completely dissolve, ensuring efficient release of contents and maintaining containment of active agents during distribution and use, while maintaining sufficient Geometric Mean Tensile Strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single hole is added to the film wall material for degassing, then processing capability is improved, but dissolution performance remains insufficient
Solution Approach 1:
The patent applies porous materials by creating multiple apertures (0.5-5.0 mm in diameter) in the film wall material. These apertures enable water to penetrate through the pouch wall during use, significantly improving dissolution performance and reducing dissolution time from hours to minutes, while maintaining containment integrity during distribution.
Solution Approach 2:
The patent segments the film wall material by creating multiple discrete apertures distributed across the pouch surface. This segmentation allows water to enter at multiple points simultaneously, accelerating the dissolution process and enabling complete breakdown of the pouch material, thereby resolving the contradiction between processing ease and dissolution performance.
2Reliability
If film wall material is used for pouch construction, then containment during distribution is achieved, but Rupture Time and Dissolution Time are excessively long
Solution Approach 1:
The patent applies local quality by creating specific regions of apertures in the film wall material while maintaining intact film in other areas. The apertured regions (with 0.5-5.0 mm holes) allow rapid water penetration and dissolution during use, reducing dissolution time significantly, while the overall pouch structure maintains containment integrity during distribution and handling.
Solution Approach 2:
The patent applies dynamics by designing the pouch to transition from a contained state during distribution to a dissolving state during use. The apertured film wall material remains stable during storage and transport but rapidly dissolves when exposed to water, achieving complete breakdown in minutes rather than hours, thus resolving the time loss contradiction.
3Stability of the object's composition
If film wall material remains after use, then pouch structure is maintained, but consumer experience deteriorates due to attachment to cleaned items
Solution Approach 1:
The patent applies parameter changes by modifying the film wall material to include apertures that control water penetration. This creates a dynamic system where the pouch maintains structural integrity during distribution but transforms during use by allowing water to penetrate through apertures, facilitating complete dissolution and eliminating residual film material that could attach to cleaned items.
4Loss of time
If apertures are added to film wall material to improve dissolution, then Dissolution Time is reduced, but Geometric Mean Tensile Strength decreases
Solution Approach 1:
The patent applies porous materials by incorporating apertures with specific diameter ranges (0.5-5.0 mm) in the film wall material. This porous structure enables rapid water penetration and dissolution while maintaining sufficient tensile strength for containment during distribution. The aperture size and distribution are optimized to balance dissolution performance with structural integrity.
Solution Approach 2:
The patent applies local quality by creating apertured regions in specific areas of the pouch wall while maintaining film integrity in other regions. This localized aperturing allows the pouch to achieve rapid dissolution where needed while preserving overall structural strength for containment during storage and transport, resolving the contradiction between dissolution speed and tensile strength.
