UAV(unmanned aerial vehicle), which is commonly known as a drone is enlarging its applications in the many different fields. The drone was originally developed for military use, but it is now used for various purposes such as photography, traffic control, leisure, and delivery (Kim, S.-H., 2016).
Drone delivery not only reduces the cost of maintenance than using traditional delivery transportation such as trucks or scooters but also reduces the labor cost by saving manpower for driving. Since the drones are less limited by obstacles such as traffics, buildings and infrastructures, it also saves time than delivering on the ground (K. Dorling, J. Heinrichs, G. G. Messier, and S.Magierowski, 2016). Thus, major shipping companies like Amazon, UPS, DHL are increasing investment in the drone industry to innovate their current delivery methods into the new delivery system. Also, transportation companies like Uber, Ehang, Audi, Hyundai aim to commercialize PAV(personal air vehicle)to shorten the travel time at the city roads in traffic hours. Although drones are developing as a means of transportation, it has a major technical issue. Most of them is the battery issue. Commercial drones have short flight time of about 5~20min, and it cannot deliver heavy objects weighting over 2~3kg for a long distance. This issue greatly reduces the potential of drone use by restricting the flight time range and limiting the weight of the objects to be transported. To solve this, first, this study aims to find a practical battery solution which can be applied in the current market. Focusing on the loadable drones, various fields such as agriculture, photography & inspection, light, and heavy weight delivery have been analyzed in terms of usage and its limitation by battery issue. Researching various battery solutions, it compares the pros and cons of each solution. Through this, it defines suitable solution for the current market available within 3~5 years. Second, utilizing flight time solution, it aims to suggest new drone applications. It aims to find various use contexts of wired battery solution. Through the ideation, it makes a context tree and defines design requirements for 3 selected contexts. By presenting a range of use contexts and scenarios, it aims to deliver new user value through the long-term flight and sufficient loads, which has not been possible with previous drone technology. Third, selecting 3 use contexts, it describes ideation, testing & refinement, development process and the output of 3D modeling and prototypes of a final concept.
