ORIGAMI-INSPIRED MECHANISMS
EXPLAINED
What is a mechanism?
A mechanism is a mechanical device used to transfer or transform motion, force, or energy. Mechanisms typically use links and pin joints to achieve their motion.
What is Origami?
Origami is the Japanese term for the ancient art of folding paper. It typically involves patterns of creases arranged to create shapes and forms.

Origami-Inspired Mechanisms
While originally used as an art and craft, it has evolved to be a valuable inspiration for engineered systems. The images below show how a practical, engineered system can be created using a simple origami pattern.
In the left image, the mechanism is modeled as a simple origami paper pattern. The right image shows the pattern adapted as a barrier that can fold flat and then be rapidly deployed.
Research was recently published on origami-inspired mechanism design in the journal Mechanical Sciences.
To allow motion, the mechanism's folding lines must operate similarly to the paper pattern regardless of hinge used. Origami-inspired mechanisms can be created from a wide variety of materials. Below is an animation showing the evolution of an origami-inspired mechanism from paper prototype to finished design.
Advantages of Origami-Inspired Mechanisms
Prototyping is fast and cheap because it can be done with paper before using other materials. Instead of relying on laser cutting or 3D-printing, rapid prototyping is possible using only hands and paper.
Many resources and patterns already exist that can be adapted for engineering purposes. Books and papers have been written and published detailing how designs can be created and modified. Because it is such an ancient art, a lot of legwork has been done already.
Challenges of Origami-Inspired Mechanisms
Thick folding, which is the application of origami principles to thick materials like wood or plastic, can prove challenging. This is because considerations must be taken for the flexible segments to deliver the same motion their paper counterparts could easily achieve. This creates unique challenges in the design of panel and hinges. We (along with others) have discovered ways to overcome these challenges.
