Elastic Stiffening Layer for Vehicle Blind Deformation

The patent applies composite materials by combining multiple layers with different properties: a decorative fabric layer for aesthetics, a foam layer for rigidity and insulation, and a mesh layer for structural support. This composite structure achieves the required resistance to deformation without increasing overall weight, as each layer contributes its specific strength characteristics.

The patent uses a foam layer as a flexible stiffening element that provides rigidity while maintaining flexibility for winding and unwinding operations. The foam layer acts as a thin film that resists deformation forces while keeping the overall canvas lightweight and manageable.

The foam layer serves as a flexible stiffening element that maintains canvas flatness when deployed but allows the canvas to be easily wound and unwound during operation. The foam's cellular structure provides rigidity while maintaining flexibility, resolving the contradiction between shape maintenance and ease of operation.

The combination of decorative fabric, foam, and mesh layers creates a composite structure where the fabric and mesh provide flexibility for handling while the foam maintains flatness. This multi-layer composite achieves both aesthetic flatness and operational ease.

The patent uses a multi-layer composite structure where each layer is thin but contributes specific mechanical properties: the decorative fabric provides surface strength, the foam provides core rigidity, and the mesh provides tensile strength. This composite approach achieves high mechanical resistance with minimal overall thickness compared to using a single thick layer.

Each layer in the composite is optimized for its specific function and placed where most needed. The foam layer provides localized rigidity where required, while the fabric and mesh layers provide surface and structural strength respectively, achieving high mechanical resistance with minimal overall thickness.
