Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reusable hygiene articles face challenges in balancing user friendliness, functionality, and minimizing waste generation, while also addressing issues of absorbent capacity, bulkiness, and incompatibility with skin-friendly additives due to washing requirements.
Innovation Solution
A reusable article chassis with a liquid intake zone and a separate absorbent pad system, designed for efficient fluid handling and compatibility with skin-friendly additives, allowing easy replacement and customization, and featuring materials that withstand multiple wash cycles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If reusable hygiene articles are designed with washable materials, then environmental footprint is reduced, but absorbent capacity and skin-friendly additives become incompatible due to washing requirements
Solution Approach 1:
The hygiene article is divided into two separate components: a reusable chassis that can be washed and reused, and a disposable absorbent pad that is replaced after use. This segmentation allows each component to be optimized for its specific function without compromise - the chassis for environmental sustainability and the pad for absorbent performance.
Solution Approach 2:
The absorbent pad is extracted as a separate removable component from the chassis. This allows the absorbent materials and skin-friendly additives to be concentrated in the disposable pad, which can be optimized for maximum absorbency without concern for washing durability, while the chassis remains washable and reusable.
2Quantity of substance
If reusable products are designed with high absorbent capacity, then liquid handling performance is improved, but product bulkiness increases
Solution Approach 1:
The absorbent pad is designed with localized high-absorbency zones positioned at the crotch region where liquid exudates are most likely to occur. This allows maximum absorbent capacity to be concentrated where needed, rather than uniformly distributed throughout the entire product, thereby reducing overall bulkiness.
3Reliability
If reusable hygiene articles are designed to be washed frequently, then hygiene maintenance is improved, but skin-friendly additives and bacterial growth inhibitors become ineffective
Solution Approach 1:
The absorbent pad is designed as a disposable component that is replaced rather than washed. This eliminates the need for washing the pad, preserving the effectiveness of skin-friendly additives and bacterial growth inhibitors throughout the product's use life. The disposable nature ensures hygiene maintenance through replacement rather than washing.
4Ease of operation
If reusable hygiene articles are designed for easy replacement, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The clear separation between the chassis and absorbent pad creates a simple replacement mechanism. The absorbent pad can be easily removed and replaced without complex operations, while the segmentation itself provides the simplicity needed for easy user operation.
