Rolling Cones is a soft e-paper screen. It can change the message and display on the screen, and also be transported in large quantities. After being pushed in a push-up manner, skeleton-cut out can reduce the wind drag and support foot to stand on an uneven road. The bottom can add heavy objects as a medium and long-term construction.
Rolling Cones can stretch the e-paper display into the next Rolling Cones to form a warning fence or wrap the e-paper display on itself. With the App, it can transmit the selected or input information on the e-paper screen to enhance the warning effect. The E-paper also can enhance the visibility at night.
