In this paper, when wheelchair user get into the vehicle, we have thorough grasp of the problems of loading wheelchair and give effect to suggest conceptual design in relation to develop manufactured goods. We choose 50 participants with disabilities who manual wheelchair or motor scooter users are able to drive own's vehicle, and the method practice in the direct survey. There are some limitations in this study especially in terms of the sampling population. The 88%(n=44) of the participant replied to the driver with disabilities need assistive devices for loading manual wheelchair. They prefer a system that robot arm brings the wheelchair out of the trunk to the driver's seat door.

An automated mechanical parking system with a dedicated multi-floor building has been studied for improvements. Among the major components of the system, study is focused on the trolly which is the most important to the overall reliability of the system. The trolley holds and moves a parked vehicle horizontally into a specified position for the next sequence of operations. Optimization of a trolly structure is presented for strength and simplicity. With optimization, the weight has been reduced by 30% with respect to the conventional design.
