ABSTRACT
Dropping a heavy object due to having a slippery grip on it could lead to all kinds of unfortunate events, including broken toes or a damaged device. These are two of the arguably more obvious consequences of slippery conditions. But, consider the potential consequences of a slippery seat on a tractor, a slippery surgical instrument, or a slippery handle on a stroller. When it comes to people “losing their grip,” smooth surfaces are a common culprit, suggesting the need to roughen them up somehow. One solution is to add texture, such as knurling or ridges on a tool’s handle, but a popular alternative is overmolding with a high-friction material, such as thermoplastic elastomer, that can feel quite smooth but also provides a good grip. One approach is to give an object a shape that helps keep hands, feet, and bottoms in place.
