Rulers play an important role in measuring objects in our daily life. However, most conventional rulers we used perform poorly due to functional limitations such as measuring overlong objects and measurements might not be accurate. HOZO Design launched the first digital product, ROLLOVA, in 2018. HOZO provides the aesthetics of technology to global consumers through a variety of smart devices.



Part 1. What is Rollova?

ROLLOVA is a pocket-friendly ruler which takes the pain out of measuring surfaces, materials, and objects. It’s inspired by the circumference of the circle. ROLLOVA equip with an internal precision sensor that can record straight, curved, even uneven objects. With one easy roll at a time, ROLLOVA provides you with an accurate measurement on its digital and high-contrast OLED screen.

As China's leading digital additive manufacturing solution provider, Wenext has established a close relationship with HOZO Design since 2017. Wenext's mission is to help our clients transform their ideas into products and launch to market efficiently and effectively. Wenext worked with HOZO Design on the preliminary design verification.

Mr. Liang, founder and design director of HOZO Design, commented: “Using 3D printing during product verification is effective and helps to reduce the cycle of research and development. We could conduct product verification in the speed of light. We received the 3D printed model in the morning, redesign the part in the afternoon and submit for new order at night. We couldn’t have done that without the help of Wenext and 3D Printing.”

Wenext established a good and trusting relationship with HOZO Design through the preliminary product verification process. On this basis, HOZO Design awarded Wenext ROLLOVA mass production project. Wenext has the advantage of automated in-house supply chain hence Wenext completed the mass production of HOZO Design parts including molding, injection molding, CNC machining process, and more. Wenext produced more than 70% of the part.

ROLLOVA's popularity is expected as such subversive design deserves everyone's admiration. It heralds the beginning of HOZO Design's exploration of extraordinary technologies. We believe the collaboration between HOZO Design team and Wenext will create good products that could benefit people.
