Introduction

Curventa, an award-winning industrial design consultancy has introduced a professional safety head gear, by combining its expertise and innovation in the field of product design.

In collaboration with Ogle Models, the company has created this functional prototype model with the help of breakthrough technologies and some Formula 1 pit crews, to provide extreme protection to snowboarders on the slopes.

Curventa’s Snowboarding Helmet – Key Technology

Curventa’s helmet, SCAR, was specifically designed to provide multi-functional protection to snowboarders at freezing temperatures and high altitudes.

The helmet was integrated with goggles, and a detachable face-mask to cover the head from extreme weather conditions. The face-mask is provided with air intake apertures to allow continuous air flow.

Curventa team collected precise information on human head dimensions for a proper fit, using in-house 3D laser scanning techniques. With this information, a full 3D CAD model was created in SolidWorks. Further, in association with Ogle Models & Prototypes, Curventa identified the best method of producing each component of the helmet.

The complex parts of the helmet were designed using a high resolution additive manufacturing technique - stereolithography (SL). Unlike other conventional additive methods, this technique enables convenient manufacture of complex forms within the helmet and produce superior surface finish of the product. In addition, Ogle’s skills and expertise in finishing ensure quality models and prototypes.

Design of Snowboarding Helmet

Upper shell of Helmet

Ogle’s 3D Systems SLA 7000 machine was used to produce the upper shell of the helmet using a clean material hand finished to a 2000 grit. The upper shell was chrome-plated. Following this, the plated shell was further hand-finished to 600 grit wet and dry by Graham Barton at 3DDC, to eliminate the build lines in the prototype. To improve adhesion property between the metal layer and substrate, the model was etched.

3DDC’s proprietary Metalise it... process designed for use in 3D printed parts, was used to make the model conductive suiting the needs of 3D printed parts. The component was then electroplated using copper at a low temperature to 120µm thickness, in order to avoid distortion of SLA materials. The electroplated layer was then polished to provide a glossy finish over which layers of nickel and decorative chrome were coated.

Lower Shell of Helmet

The lower shell of the helmet was fabricated using SL techniques and coated with a special paint that resembles rubber finish.

Firstly, the goggles were produced by forming the SLA model using the highly versatile SL technique. During SLA model creation, a silicon tool was used in a soft PU rubber to form the goggles, mimicking the manufactured parts. The lenses, however, was made of a transparent material and then coated with a clear lacquer layer to provide maximum clarity.

Model Stand for Demonstration

In order to exhibit the model, Curventa designed a strong, durable, head-shaped stand to place the final helmet model. The stand was manufactured by capturing the 3D scanned data of a head using a Laser Sintering (LS) system. Perspex containing uprights was machined to produce the stand base carrying the head model of the helmet.

Conclusion

The elasticated band used in the goggles was the only part Ogle has to outsource for designing, besides the upper shell sourced using 3DDC. Continuous investment in its personnel expertise and technology has proved Ogle as a suitable partner for creating exceptional prototypes and models. The remarkable product of Curventa and Ogle Models, SCAR helmet, is ready for launch in the coming weeks at various occasions worldwide.
