Modular construction and origami unite in promising new research, resulting in MUTOIS.
Origami has always fascinated with its intricate designs, but turning these delicate paper folds into robust, practical structures has been a significant challenge, until now. Researchers at the University of Michigan have developed the Modular and Uniformly Thick Origami-Inspired Structure (MUTOIS), a system that offers a versatile and strong method for modular construction.

Innovative design for practical applications
MUTOIS overcomes the inherent limitations of traditional origami structures, which are often too thin to support heavy loads or too rigid to fold effectively. The researchers created uniformly thick panels connected by rotational hinges, allowing the structure to fold into various shapes and lock into place to support substantial weights.
“These origami-inspired systems offer new philosophies for how we design and envision our built environment,” said Evgueni Filipov, an associate professor of civil and environmental engineering at the University of Michigan. “They can enable adaptable buildings where floor plans, or the entire building, are reshaped, reconfigured and added-on for new use cases. The concept also enables deconstructability and long-term re-use of the same basic origami building blocks.”
Versatility and strength
The MUTOIS system consists of triangle-shaped panels that can be arranged in multiple configurations, such as columns, trusses, and walls. This flexibility allows for the creation of various structural forms, enhancing the adaptability of the system. The panels can be produced from different materials, including those with open or closed sides to serve distinct purposes.
In practical tests, a 4-metre-long pedestrian bridge built using MUTOIS supported five people with minimal deformation. A 1-metre-long column constructed from the same panels was capable of bearing over two tons of force. These results showcase the system’s significant load-bearing capacity and potential for various real-world applications.
Applications and future potential
The practical uses of MUTOIS are extensive. Its lightweight and adaptable nature makes it suitable for modular construction, constructing bridges, shelters, stages for live events, and even space structures. The system’s ability to transform and support heavy loads while maintaining structural integrity is a key advantage in these applications.
Deploying MUTOIS involves locking the hinges and lifting the structure at specific points, also making it a practical solution for civil engineering projects. According to the researchers, this method eliminates the need for specialised actuators, reducing construction costs and complexity.
The ongoing research aims to explore the potential of higher-order vertices (an origami pattern where more than four folds meet at a single point) with more links and specialised connectors, such as self-latching devices. These developments are aimed at enhancing the system’s load-carrying performance and speed up assembly processes.
Industry implications
The researchers are optimistic that MUTOIS will deliver a new approach to modular construction techniques. By integrating origami principles with practical engineering solutions, the University of Michigan team has created a system that may well address many of the challenges associated with traditional construction methods.
