Challenges & Opportunities
Reliable connectivity in all environments
The technology in the shoes is powered by a high-performance battery. VRaktion had long been on the lookout for the ideal connectivity solution to recharge it. First, they tried micro-USB connections. But these were not robust enough. On a trade fair visit in Germany, the VRaktion team visited Fischer Connectors’ booth with a prototype. Over the course of the conversation, they finally identified connectors from the Fischer Freedom™ Series as a possible solution. Since the Fischer FreedomTM Series connectors are not only very robust and easy to clean, but also very powerful in a highly compact form, they proved to be the ideal solution for the shoe.
Since the shoes are used primarily in dusty, damp or dirty environments and are exposed to vibrations and impacts, for example from objects falling on them, the technology also has to be suitably resistant. The shoes have to be able to withstand external influences as well. For example, if the shoes are worn while working on muddy ground, the connections need to be able to cope with such conditions. The Fischer FreedomTM connectors not only withstand mud and water, they are also easy to clean.
“While searching for the right connectivity solution for our smart work shoes, we visited Fischer Connectors’ booth with our prototype on a trade show visit. Over the course of our discussion we identified connectors from the Fischer Freedom™ Series as a possible solution. For example, when the shoes are worn on muddy ground during operations, the connectors have to be mud-resistant. The Fischer Freedom™ connectors not only withstand mud and water, they’re also easy to clean and, despite being highly compact, are very powerful. This makes them the ideal solution for our shoe”.Bernhard Schipper Co-founder and Product Manager of VRaktion UG
The Fischer FreedomTM Series connectors do without male-female poles, featuring surface contacts instead. A membrane protects the contacts fully from contamination and moisture up to the IP68 sealing level. At the same time, the membrane enables easy cleaning. Handling is very user-friendly too. Thanks to their lack of key code, the connectors provide a straightforward 360-degree mating capability. The blind-mate, 360-degree locking mechanism makes any false manipulations impossible and the mating process intuitive. This allows the shoe’s battery to be recharged quickly and easily after each use. Firmware updates can also be installed via the connectors. This is normally done ‘over-the-air’. However, some companies with particularly sensitive data prefer updates via cable. Both are possible.
