Lamina Emergent Torsional (LET) Array for Origami-Inspired Mechanisms ID: 2024-052

A revolutionary invention that introduces a novel method for enabling folding or hinge-like movement in origami-inspired mechanisms, optimizing for space, weight, and volume.

Technology Overview

This technology, developed by Brigham Young University's Technology Transfer Office, features a lamina emergent torsional (LET) array made from composite materials. It is designed to act as a surrogate fold, providing a local reduction in stiffness to facilitate folding movements. This innovative approach aims to replace traditional pin joints in origami-based mechanisms, offering significant benefits for space applications by being lightweight, compact, and volume-efficient.

Key Advantages

• Enables extensive rotation during folding, minimizing weight, area, and volume
• Concealable joint beneath antenna panels, avoiding overlap with the effective center of rotation
• Supported by detailed technical analysis, including mathematical modeling for deflections and stresses
• Optimized for space applications, particularly beneficial for deployable antennas

Problems Addressed

• Reduces the need for traditional pin joints, overcoming limitations in weight, space, and complexity
• Improves the efficiency and compactness of folding mechanisms in space applications
• Addresses the challenge of integrating folding mechanisms without compromising on performance or volume

Market Applications

• Deployment mechanisms for space applications, such as satellites and spacecraft
• Folding phased array antennas for communication systems
• Origami-inspired mechanisms across aerospace, defense, and commercial sectors
• Potential licensing opportunities for companies specializing in deployable space structures
