Origami-inspired deformation for flexible materials in hygiene products
This research explores the use of origami-inspired crease patterns in flexible materials to achieve predictable 3D deformation, enhancing the fit and performance of diapers and menstrual pads. Experimental validation will confirm its effectiveness in improving material conformance to complex shapes.
Overview
The proposed solution leverages origami-inspired crease patterns to enable predictable 3D deformation of flexible sheet materials. This innovative approach is designed to enhance the fit and performance of hygiene products such as diapers and menstrual pads by improving their ability to conform to complex body shapes. The incorporation of these patterns allows for controlled deformation under compressive forces, potentially leading to better product functionality and user comfort.
Technical specifications
Key features:
- Origami-inspired crease patterns enable predictable and controlled 3D deformation.
- Enhanced material conformance to complex shapes, improving fit and performance.
- Focus on applications in hygiene products like diapers and menstrual pads.
- Experimental validation includes 3D-scanned geometries and realistic, skin-like fixtures.
The research involves defining target geometries using molding or 3D scanning, characterizing material properties such as folding and bending stiffness, and developing a framework for predictable deformation. Experimental tests will validate the patterned sheets' performance on fixtures replicating body shape and texture.
Technology readiness level
This technology is currently at TRL 3, indicating it has been validated experimentally in a lab setting. The next steps involve further validation and refinement for potential commercial applications.
