The team has been tasked with designing a compact mechanism capable of deploying and retracting the Rolatube horizontally and vertically at a controlled rate in confined spaces (i.e. tank housing structures). Because workers are confined to tight quarters, a mechanism to aid in common activities is at times required. The mechanism will allow for tool deployment with attachments for easily sending tools and utilizing cameras. It will also be used to assist workers in stringing lights, keeping wires organized, and delivering hoses and tubes. This design will allow workers at Newport News Shipbuilding (NNS) to save time and energy while working in the tight confines of modern naval vessels. Several constraints pertaining to the deployment methods must also be considered. The method in which the extension mechanism operates shall not interfere with mounting. The product shall mount to stainless steel surfaces. This mechanism shall withstand a wide range of conditions, including high temperatures, humidity, corrosive substances, and dirt/grime. In order to fulfill multiple roles, the design should allow for the tube to remain attached after deployment or allow it to be separated from the mechanism.
