Product Search amp Selection Analysis Problem Statement Q Low profile cars are difficult to raise and support Without incurring problems 9 Inability to properly raise and support these cars hinders service and maintenance 0 Current jacks on the market do not start low enough Q Current ramps are either too steep of a grade or theyvv do not allow enough clearance to perform service 397 Problem Solution Q The goal is to design a mechanism to raise and support a low profile car to adequately perform service 9 The product should be cost efficient and easy to operate Current Solution to Lifting
