Background

Our company is seeking innovative approaches to better understand and predict how flat, soft, and flexible sheet materials and articles, such as those used in diapers and menstrual pads, behave when compressed or squeezed into 3D shapes, particularly when in contact with the body. These compressible, deformable materials often face performance issues like bunching during use, which compromises their effectiveness. A deeper understanding of how such materials transition from flat sheets to complex 3D shapes under mechanical stresses and conform to complex geometries like the crotch would enable better product design and optimization to improve user comfort and functionality.

What we're looking for

We are seeking innovative models, research, tools and methodologies to simulate the compliance and deformation of soft materials in contact with the body. The goal is to predict how these materials bend, compress, and conform to the body's complex geometries, particularly in the crotch area. These simulations should help in assessing product fit and comfort.

Solutions of interest include:

Predictive and 3D mathematical models, including differential geometry and topology
Tools for classifying and categorizing 3D shapes
Simulation tools or models for bending, compression, buckling analysis and material behavior prediction
Simulation focusing on how materials conform to complex body geometries, especially the crotch region
Tools for assessing compliance (ability to bend, flex, or conform) of soft deformable materials in contact with the body
Origami and kirigami-inspired methodologies for understanding material behavior
Physical models to study material deformation in 3D
Digital tools for analyzing mechanical properties and 3D deformations
Experimental setups to observe and test deformation dynamics
Graphical models that simulate the behavior of compressible, bendable, and deformable materials
Real-time or fast simulations that complement traditional mechanical analysis and modeling approaches such as Finite Element Analysis (FEA)
Validation approaches for graphical models, including physical measurements to ensure accuracy

What's out of scope:

General studies on material properties that do not focus on deformation into 3D shapes and compliance
Solutions that do not apply advanced mathematical or modeling techniques
Approaches that apply only to rigid materials
Solutions aimed at creating movies or games
Models without validation or physical measurement components
FEA simulations alone

Acceptable technology readiness levels (TRL):

Levels 3-9
